A. Fire Safety
T
o provide reasonable re safety, the following should be
given serious consideration:
• Install at least one smoke detector on each oor of
your home.
• Install at least one carbon monoxide detector on each
oor of your home.
• Locate smoke detector away from the heating
appliance and close to the sleeping areas.
• Follow the smoke detector manufacturer’s placement
and installation instructions and maintain regularly.
• Follow the carbon monoxide manufacturer’s placement
and installation instructions and maintain regularly.
• Conveniently locate a Class A re extinguisher to
contend with small res.
• In the event of a hopper re:
- Evacuate the house immediately.
- Notify re department.
B. Combustible/Non-Combustible Materials
• Combustible Material
- Material made of or surfaced with wood,
compressed paper, plant bers, plastics, or any
material capable of igniting and burning, whether
ame-proofed or not, plastered or non plastered.
• Non-combustible Material
- Material which will not ignite and burn. Such
materials are those consisting entirely of steel,
iron, brick, tile, slate, glass or plasters, or any
combination thereof.
• Non-combustible Sealant Material
- Sealants which will not ignite and burn: Rutland,
Inc. Fireplace Mortar #63, Rutland 76R, Nuex
304, GE RTV106 or GE RTB116 (or equivalent).
C. Fuel Material and Fuel Storage
Pellet fuel quality can greatly uctuate. We recommend that
you buy fuel in multi-ton lots whenever possible. However,
we do recommend trying various brands before purchasing
multi-ton lots to ensure your satisfaction.
Fuel Material
• Made from sawdust or wood by-products
• Depending on the source material it may have a high
or low ash content.
Higher Ash Content Material
• Hardwoods with a high mineral content
• Fuel that contains bark
• Standard grade pellets or high ash pellets
Lower Ash Content Material
• Most softwoods
• Fuels with low mineral content
• Most premium grade pellets
D. Before Your First Fire
1. First, make sure your appliance has been properly
installed and that all safety requirements have been
met. Pay particular attention to the re protection
and venting.
2. Double check that the rebox is empty and the repot
is in place!
3. Close and latch the door.
Clinkers
Minerals and other non-combustible materials such as
sand will turn into a hard, glass-like substance called a
clinker when heated in the repot.
Trees from dierent areas will vary in mineral content. That
is why some fuels produce more clinkers than others.
Moisture
Always burn dry fuel. Burning fuel with high moisture
content takes heat from the fuel and tends to cool the
appliance, robbing heat from your home. Damp pellet fuel
can clog the feed system.
Size
• Pellets are either 1/4 inch or 5/16 inch (6-8mm)
in diameter
• Length should be no more that 1-1/2 inches (38mm)
• Pellet lengths can vary from lot to lot from the same
manufacturer
• Due to length variations, the feed rate may need
adjusting occasionally
Performance
• Higher ash content requires the repot and the ash
drawer to be emptied more frequently
• Hardwoods require more air to burn properly
• Premium wood pellets produce the highest heat output
• Burning pellets longer than 1-1/2 inches (38mm) can
cause an inconsistent fuel feed rate and/or missed
ignitions of feed jams.
Storage
• Wood pellets should be left in their original sealed bag
until using to prevent moisture absorption
• Do not store any pellet fuel within the clearance
requirements or in an area that would hinder routine
cleaning and maintenance

B. User Dial Control
The appliance has one dial control located on the side of
the unit used for daily operation.
There are four primary
settings on this dial.
• O:
- When the dial indicator is in the o position the unit
will go into a shut down and remain o until the dial
is turned to one of the other three settings. The
LED will ash green once per second when in the
o position.
• MIN:
- When the dial indicator is directed to the MIN
setting (small ame on the label) the unit will burn
on low until the hopper runs out of pellets or the
dial control is turned to a dierent setting. When
in this setting the LED will be amber in color and
continuously on. When burning in this mode, the
unit should be turned o at least once daily for
cleaning. If lower quality fuels are used, additional
daily shut downs may be required for cleaning.
• MAX:
- Similar to the MIN mode, the unit will run
continuously at the high burn rate until the unit has
run out of fuel or the dial is turned to a dierent
setting. To operate in this mode, turn the dial
clockwise until it stops. The dial indicator will point
to the large ame. When in this setting the LED will
be amber in color and continuously on. Follow the
daily cleaning recommendations when operating in
this mode. If lower quality fuels are used, additional
daily shut downs may be required for cleaning.
• AUTO:
- To burn in the Automatic mode, turn the dial
control clockwise to the desired comfort level.
When operating in the automatic mode, the unit
changes the burn setting based on the dierence
between the room temperature and the desired
set point. In other words, the unit will burn on High
if the dierence between the desired and room
temperature is greater than 8 degrees Fahrenheit.
As the room heats up and the gap closes, the unit
will automatically reduce the burn rate. When the
room temperature is close to the set point the light
will stop ashing stay solid green. At this time the
stove will be burning on the lowest burn rate. When
the desired temperature is achieved the unit will
shut down. As the room cools, the unit will restart
automatically. When burning in this mode the LED
will be blinking green. The number of green ashes
corresponds to the current burn rate.
C. Filling the Hopper
Slowly open the hopper lid by lifting the handle. The
medium and large units have a locking latch that will
engage when the hopper lid is fully opened. The hopper lid
for the cabinet will open past ninety degrees and stay open
automatically. Fill the hopper with fuel. FOR USE WITH
ONLY WOOD PELLET FUEL. Slowly close the hopper lid.
See gure below for releasing the latch.

E. Firepot Burn Down
A
feature of these pellet appliances is the repot burn down
cycle. The frequency of the cycle is once every hour the
appliance is burning. During this event, the feed is reduced
to the lowest setting and the exhaust blower ramps up to
the highest setting. The purpose of the burn down cycle
is to help remove debris from the repot and help the
appliance burn as ecient as possible. The cycle lasts 99
seconds. Please be aware that the burn down does not
replace daily cleaning activities but makes them easier.
F. Shutdown
To shut the appliance down, turn the dial control counter
clockwise to the OFF position. During the shutdown
process, the LED will ash amber or green rapidly just like
the ignition sequence. The repot burn down cycle will
begin but without the feed motor running. The feed will be
terminated during this shutdown process. The exhaust and
convection blowers will remain on during the shutdown
process until the exhaust has cooled.
If maintenance or daily cleaning is going to be conducted
immediately following a shutdown, please use caution as
components especially those inside the rebox may still
be hot.
Please note that if the dial control is turned to the o
position and back on even if by mistake, the appliance
will go through the shutdown sequence.
Return the repot to the appliance in the correct orientation.
See gure in Cleaning Fire pot in the General Maintenance
section of Owner’s Manual under Maintaining and Servicing
the Appliance.
Attempt relighting sequence (see Lighting
Instructions Guide).

CAUTION
Do not restart or manually add pellets or any type of fuel to
the burn pot during this process.
G. Starting Your First Fire
1. Turn the dial control to “OFF”.
2. Make sure the repot is clean, in place, and free
of debris.
3. Plug the appliance into the wall and ll the hopper
with wood pellets. Shut the hopper lid.
4. Turn the dial control to the desired burn setting.
The appliance will go into the ignition sequence followed
by start up (The green LED will ash rapidly). The ignition
sequence involves the exhaust blower turning on, the
igniter turning on, and the feed motor running in two
stages. The rst stage involves the feed motor running
continuously for about a minute to preload pellets into the
repot. Following the preload and a delay, the feed motor
will begin cycling on and o. When the pellets are warming
up and on the verge of igniting, it is not uncommon for the
rebox to ll with smoke. Once ignition actually happens,
the smoke should evacuate quickly. During this stage
as well as any part during the burn process, the front
door should not be opened. This cycle continues until
the appliance senses ignition by a rise in the exhaust
temperature or the appliance times out. Following the
ignition cycle the appliance begins to feed additional
pellets gradually for a few minutes to build up the re.
This is important to have a controlled start up to keep the
appliance in balance.
If the appliance does not ignite, the LED light will blink
red four times showing a missed ignition alarm. Turn the
appliance to o and remove and EMPTY the repot.

H. Fire Characteristics
The overall height of the ame will vary throughout the
burn for a couple of reasons. First is that the ame will vary
based on type of fuel or even batch of fuel. Secondly
, the
appliance adjusts the burn rate according to the how far
away the room temperature is from the set temperature.
This should not cause alarm. The third characteristic
that aects the re relates to general maintenance and
cleaning. Infrequent or poor general maintenance will
result is poorer performance. Indicators of the need for
additional maintenance activities include a lazy ame,
black sooted glass, pellets not igniting, or pellets falling
to the side of the repot. See the maintenance section for
additional information.
Odors, vapors, and smoke released during
initial operation.
• Curing of high temperature paint.
• Open windows for air circulation.
Odors may be irritating to sensitive individuals.
CAUTION
I. Ignition Cycles
1. At the beginning of each ignition cycle, it is normal to
see some smoke in the rebox. The smoke will stop
once the re starts.
2. The convection blower will automatically turn on after
your appliance has been burning for approximately
10 minutes.
3. This blower transfers heat from your appliance into the
room, and will continue to run even after the unit has
shutdown. It will turn o after the exhaust temperature
has cooled.
4. Occasionally the appliance may run out of fuel and
shut itself down. When this happens the empty hopper
alarm will be triggered.
J. Running in Minimum or Maximum
When the dial control is set to run on the minimum or
maximum setting, the appliance will continue to run without
regard to the actual temperature in the room. The appliance
will shut o only if the dial control is set to a dierent setting
or there is an error such as an empty hopper.
When running on minimum or maximum it is important to
follow the daily cleaning activities especially cleaning the
repot. Failure to do so will reduce the performance of
the appliance.
K. Running in the Automatic Mode
When the dial control is set to run in the automatic mode
the unit will adjust the actual burn rate based on the
dierence between the room temperature as sensed by the
probe located in the rear of the unit and the desired comfort
level as set on the dial control.
The comfort level range is from 65 degrees Fahrenheit to
82 degrees Fahrenheit.
M. Clear Space
NOTICE: Clearances may only be reduced by means
approved by the regulatory authority
having jurisdiction.
Mantel: Avoid placing candles and other heat-sensitive
objects on mantel or hearth. Heat may damage
these objects.
WARNING!
RISK OF FIRE!
Do NOT place combustible objects in front or to the sides
of the appliance. High temperatures may ignite clothing,
furniture or draperies.
WARNING!
RISK OF FIRE!
Keep combustible materials, gasoline and other
ammable vapors and liquids clear of appliance.
• Do NOT store ammable materials in the
appliance’s vicinity.
• Do NOT use gasoline, lantern fuel, kerosene,
charcoal lighter uid or similar liquids to start or
“freshen up” a re in this heater.
Keep all such liquids well away from the heater while it is
in use as combustible materials may ignite.
L. Trim Adjustment
Trim adjustment is the small dial located below the main
dial control. Rotating this dial will adjust the air/fuel ratio
and below are examples of when to use it:
• If the re is too large, lazy or producing black soot,
rotate the dial counterclockwise one level at a time
and allow 15 minutes for stabilization before making
another adjustment
• If your re is too small and sometimes goes out
when there are pellets in the hopper, rotate the dial
clockwise one level at a time and allow 15 minutes for
stabilization before making another adjustment.
Once the desired comfort level is achieved the appliance
will automatically shut down and turn o. When the
temperature in the room drops 3 degrees below the desired
comfort level, the appliance will automatically restart.

The type of fuel you are burning will dictate how often you
have to clean your repot.
If the fuel you are burning has a high dirt or ash content,
it may be necessary to clean the repot more than once
a day.
Poor quality fuel will cause clinkers to form in the repot.
A clinker is formed when dirt, ash or a non-burnable
substance is heated to 2000°F (1093°C) and becomes
glass-like. See section D following for more details on fuels
with high ash content.

The products of combustion will contain small particles
of y ash. The y ash will collect in the exhaust venting
system and restrict the ow of the ue gases.
At start-up if there is incomplete combustion, or if there is
a shutdown or incorrect operation of the appliance it will
lead to some soot formation. This will collect in the exhaust
venting system.
The venting (chimney) system may need to be cleaned at
least once a year or more often depending upon the quality
of your fuel or if there are any horizontal pipe sections.
Ash will build up more quickly in the horizontal sections
and elbows.

• Frequency: As needed
• By: Homeowner
Poor quality pellet fuel, lack of maintenance, or if the small
dial control is set to a less than optimum setting, poor
combustion conditions that make the repot ll quickly with
ashes and clinkers.
This condition makes the appliance susceptible to
overlling the repot with pellets which may result in
smoking, sooting and possible hopper res. The gure
below shows an example where the repot overlls, pellets
back up into the feed tube and ash has accumulated in
the rebox.

E. Frequently
Asked Questions
What causes my glass to become dirty?
If the glass has white ash build up it is normal and the glass should be cleaned. If it is a black soot build up airow through
the unit may be restricted. The most often cause is overdue maintenance and cleaning. See “Maintaining and Servicing
Appliance” in the owner’s manual and/or make adjustments to the trim control.
How can I get more heat out of the appliance?
The most often cause of diminished heat output is overdue maintenance and cleaning. See “Maintaining and Servicing
Appliance” in the owner’s manual.
What should I do if I smell smoke or there is ash/soot coming from the appliance?
While there will always be some smoke smell from wood burning appliances (including pellet) you should investigate all
venting to make sure it is sealed properly. Most venting requires silicone to seal the seams. In addition most homes are
built very tight today and with exhaust systems can create negative pressure in the home. See “Negative Pressure” under
“Getting Started” in the owner’s manual if you have checked the venting but still have smoke coming from the appliance.
For ash or soot check the above and the exhaust blower housing and seals.
Why would my appliance run ne last winter but not start this fall?
It is possible that the stove was not properly prepared for the Non-burn season. See “Troubleshooting” in the owner’s
manual.
Why would the metal on the inside of the appliance begin to ake?
There are some pellet mills that get their raw materials from lumber mills that purchase logs that are transported in
sea water. These pellets can have a higher salt content and cause the metals in the unit to corrode prematurely and
deteriorate. If you are seeing any components inside the rebox deteriorate it is recommended to change pellet brands
immediately.
Is there a place to lubricate the blowers to quiet them down?
The most often cause of noisy blowers is from the impellers becoming dirty over time. See “General Maintenance &
Cleaning” under “Maintaining & Servicing Appliance” in the owner’s manual. No form of lubrication should ever need
applied to the blowers.
What is the metal object with the bend in it for that came inside the plastic bag?
It is a clean-out tool used to help clean the repot and remove any jams in the rare event they occur in the feed tube.
Why is there a black residue building up on the outside of my home?
Wind can cause this to happen. If the appliance is operating correctly very little soot should ever exit the termination cap.
Also check to be sure the venting is installed per the owner’s manual and local codes.
Do I need an outside air kit?
Outside air is required for mobile home installs and in some jurisdictions. Refer to “Listing & Code Approvals”,“ Mobile
Home Installation” and “ Appliance Set-up” owner’s manual. Also refer to local building codes.
I am seeing sparks coming out of my pipe (termination cap) outside is this safe?
This is normal. As long as clearances to combustibles were followed this is safe.
I have no power to anything. Does this unit have a circuit breaker or fuse or a reset button?
This unit has one serviceable fuse on the control board and a resetable snap switch mounted to the feed tube.
Can I burn corn in my unit?
NO, corn is not an approved fuel.
Where is the serial # of my unit is located?
The serial # is located on the back of the stove.

A. Design, Installation & Location
Considerations
NOTICE: Check building codes prior to installation.
1. Appliance Location
NOTICE: Locating the appliance in a location of
considerable air movement can cause
intermittent smoke spillage from appliance. Do
not locate appliance near:
• Frequently open doors
• Central heat outlets or returns
Install Guide
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector,
re ocials or authorities having jurisdiction over
restrictions, installation inspection and permits.
It is a good idea to plan your installation on paper, using
exact measurements for clearances and oor protection,
before actually beginning the installation. Location of the
stove and chimney will aect performance.
Consideration must be given to:
• Safety, convenience, and trac ow
• Placement of the chimney and chimney connector and
to minimize the use of chimney osets.
• Place the stove where there will be a clear passage for
a listed chimney through the ceiling and roof (vertical)
or through exterior wall (horizontal).
• Installing the required outside air kit will aect the
location of the vent termination.
When locating vent and venting termination, the ideal
location is to vent above the roof line when possible. This
minimizes the aects of wind loading.
Since pellet exhaust can contain ash, soot or sparks, you
must consider the location of:
• Windows
• Air Intakes
• Air Conditioner
• Overhang, sots, porch roofs, and adjacent walls
• Landscaping, vegetation
• Horizontal or vertical vent termination
2. Floor Support
The supporting oor under the appliance must be able to
handle the weight of the appliance, fuel load and the weight
of the chimney.
Ensure that your oor will support these weights prior
to installation. Add sucient additional support to meet
this weight requirement prior to installation. The weight
of the stove is 195 pounds and with a full load of fuel the
maximum weight is 145 pounds.

B. Draft
Draft is the pressure dierence needed to vent appliances
successfully. When an appliance is drafting successfully,
all combustion by products are exiting the home through
the chimney.
Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
To measure the draft or negative pressure on your
appliance use a magnehelic or a digital pressure gauge
capable of reading 0 - .25 inches of water column (W.C.).
The appliance should be running on high for at least 15
minutes for the test. With the stove running on high you
should have a negative pressure equal to or greater than
the number given in the chart. If you have a lower reading
than you nd on the chart, your stove does not have
adequate draft to burn the fuel properly.
C. Negative Pressure
NOTICE: GHP assumes no responsibility for the
improper performance of the chimney system
caused by:
• Inadequate draft due to environmental conditions
• Downdrafts
• Tight sealing construction of the structure
• Mechanical exhausting devices

CAUTION
A. Chimney and Exhaust Connection
1. Chimney & Connector: Use 3 or 4 inch (76-102mm)
diameter type "L" or "PL" venting system. It can be
vented vertically or horizontally.
2. Mobile Home: Approved for all Listed pellet vent. If
using the 3 inch (76mm) vertical Top Vent Adapter Kit
or the 3 to 6 inch (76-152mm) Top Vent Oset Adapter,
use Listed double wall ue connector. An authorized
Outside Air Kit must be used with manufactured home
installations.
3. Residential: The 3 inch (76mm) vertical Top Vent
Adapter Kit and the 3 to 6 inch (76-152mm) Top Vent
Oset Adapter are tested to use 24 gauge single wall
ue connector or Listed double wall ue connector to

6. DO NOT INSTALL A FLUE DAMPER IN THE
EXHAUST VENTING SYSTEM OF THIS UNIT.
7. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVING ANOTHER APPLIANCE.
B. Venting Termination Requirements
1. Termination must exhaust above air inlet elevation. It
is strongly recommended that at least 60 inches
(1.5m) of vertical pipe be installed when appliance
is vented directly through a wall. This will create a
natural draft, which will help prevent the possibility of
smoke or odor venting into the home during a power
outage. It will also keep exhaust from causing a
nuisance or hazard by exposing people or shrubs to
high temperatures. The safest and preferred venting
method is to extend the vent vertically through the roof.
2. Distance from doors and opening windows, or gravity
or ventilation air inlets into building:
- Not less than 48 inches (1.2m) below;
- Not less than 48 inches (1.2m) horizontally from;
- Not less than 12 inches (305mm) above.
3. Distance from permanently closed windows;
- Not less than 12 inches (305mm) below;
horizontally from or above.
4. Distance between bottom of termination and grade
should be 12 inches (305mm) minimum. This is
conditional upon plants in the area, and nature of grade
surface. The grade surface must be a non-combustible
material (i.e., rock, dirt). The grade surface must not
be lawn. Distance between bottom of termination and
public walkway should be 7 feet (2.13m) minimum.
5. Distance to combustible materials must be 24 inches
(610mm) minimum. This includes adjacent buildings,
fences, protruding parts of the structure, roof overhang,
plants and shrubs, etc.
6. Termination Cap Location (Home Electrical Service)
- Side-to-side clearance is to be the same as
minimum clearance to vinyl inside corners.
- Clearance of a termination cap below electrical
service shall be the same as minimum clearance to
vinyl sots.
- Clearance of a termination cap above electrical
service will be 12 inches (305mm) minimum.
- Location of the vent termination must not obstruct
or interfere with access to the electrical service.
Vent surfaces get HOT, can cause burns
if touched. Non-combustible shielding or
guards may be required.
WARNING
NOTE: All pipe must be welded seam pipe whenever
possible. Seal pipe joints with high temperature
silicone (500°F [260°C] minimum rated only). Do
not put silicone inside of pipe.
WARNING
Fire Risk.
Follow Chimney Connector Manufacturer’s
Instructions for Proper Installation.
ONLY use connector:
• Within the room, between appliance and ceiling
or wall.

When describing the location of a component,
it is always
AS YOU FACE THE FRONT OF THE
APPLIANCE.
1. Control Board
The control board is located on the right side of the
appliance behind the lower right side panel.
2. Convection Blower
The convection blower is mounted in the rear of the
unit. It pushes air up the rear of the rebox, across the
top and out the front. As the air moves past the rebox
it is heated.
3. Exhaust Blower
The exhaust blower is mounted on the left side of the
appliance. The exhaust blower is designed to pull the
exhaust from the appliance and push it out through the
venting system.
4. Feed System
The feed system can be accessed in two areas. To
access the auger spring, remove the cover in the
hopper. To remove the feed motor, remove the side
panel and motor cover plate in the rear of the unit.
5. Firepot
The repot is made of a combination of stainless steel
and heavy duty cold rolled steel. It is removable to aid
in cleaning.
6. Fuse
The fuse is located on the control board. The fuse
will blow should a short occur and shut o power to
the appliance.
7. Dial Control
The dial control is attached to the right side of the
appliance. The large dial controls the heat output
where as the small dial below the large dial is the
trim feature. The LED blinks according to the state of
the appliance.
8. Hopper Switch
The hopper switch is located in the upper right hand
corner of the hopper. This switch is designed to
shut down the feed motor whenever the hopper lid
is opened.
9. Igniter
The igniter is mounted in the chamber in the rear of the
rebox below the convection blower. Combustion air
travels over the red hot igniter creating super heated
air that ignites the pellets.
10. Power Supply
The power cord connector in the rear of the unit.
Check the wall receptacle for 120 volt, 60 Hz
(standard current). Make sure the outlet is grounded
and has the correct polarity. A good surge protector
is recommended.
A. Component Function
11. Exhaust Probe
The exhaust probe is mounted to the side of the
exhaust outlet in the rear of the unit. It senses the
temperature of the exhaust and allows the control
system to make decisions.
12. Ambient Probe
The ambient probe is located in the back panel. It
has extra wire to increase distance from appliance
if needed.
13. Snap Disc (Back Burn Protector) 200°F
Snap disc is mounted on the back of the auger tube
in the center of the appliance and has a reset button.
There are two grey wires connected to it. To access it
remove the right side panel. If the re tries to burn back
into the feed system or push exhaust up the feed tube,
this snap disc will shut the entire system o. Unplug
the stove prior to resetting.
14. Vacuum Switch
The vacuum switch is located on the lower right side
of the appliance behind right side panel. There are
two red wires attached to it. This switch turns the feed
system on when vacuum is present in the rebox. The
vacuum switch is a safety device to shut o the feed
motor if the exhaust or the heat exchanger system
is dirty or plugged or if the rebox door is open or
exhaust blower failure.
15. Outside air inlet
The outside air tube can be attached to the 2” OD inlet
tube mounted to the rear of the rebox. To extend the
hose outside the unit there is a knockout plate that
must be removed.
