monoxide poisoning are similar to the u with headaches,
dizziness and/or nausea. If you have these signs, the re-
place may not have been installed properly. Get fresh air
at once! Have the replace inspected and serviced by a
qualied service person. Some people are more affected
by carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia,
those under the inuence of alcohol, and those at high
altitudes.
Propane/LP gas and natural gas are both odorless. An
odor-making agent is added to each of these gases. The
odor helps you detect a gas leak. However, the odor added
to these gases can fade. Gas may be present even though
no odor exists.
Make certain you read and understand all warnings. Keep
this manual for reference. It is your guide to safe and proper
operation of this replace.
1. This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases unless a certied
kit is used.
2. For propane/LP replace, do not place propane/LP
supply tank(s) inside any structure. Locate propane/LP
supply tank(s) outdoors. To prevent performance prob-
lems, do not use propane/LP fuel tank of less than 100
lbs. capacity.
3. If you smell gas
• shut off gas supply.
• do not try to light any appliance.
• do not touch any electrical switch; do not use any
phone in your building .
• immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.

comply with the established standards for DIRECT VENT
GAS FIREPLACE HEATERS in the USA and Canada as
follows:
TESTED TO:
ANSI Z21.88-2009 / CSA 2.33-2009 STANDARDS
A manufactured home (USA only) or mobile home OEM
installation must conform with the Manufactured Home
Construction and Safety Standard,
or when such a standard is not applicable, the
, or
.
It is normal for replaces fabricated of steel
to give off some expansion and/or contraction
noises during the start up or cool down cycle.
Similar noises are found with your furnace heat
exchanger or car engine.
It is not unusual for gas replace to give off
some odor the rst time it is burned. This is due
to the manufacturing process.
It is recommended that you burn your replace
for at least ten (10) hours the rst time you use
it. Place the fan switch in the “OFF” position
during this time.

There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
It is important to select the proper length of vent pipe for
the type of termination you choose. It is also important to
note the wall thickness.
Select the amount of vertical rise desired. All horizontal run
of venting must have 1/4" rise for every 12" of run towards
the termination below 7Z\x' of vertical rise from oor of re-
place. With 7Z\x feet or more of vertical rise from the oor
of the replace, the horizontal run may be level. NEVER
run vent piping down.
You may use up to three 90° elbows in this vent congura-
tion. Refer to Vertical/Horizontal Termination Congurations
on Page 21.
Horizontal venting which incorporates the twist lock pipe
must be installed on a level plane without an inclining or
declining slope.
Measure the distance from the replace oor to the ceil-
ing. Add the ceiling thickness, the vertical rise in an attic
or second story, and allow for sufcient vent height above
the roof line.
NOTE: You may use two 45° elbows in place of a 90°
elbow. You must follow rise to run ratios when using
45° elbows. The appliance is approved for use with
three 90° elbows maximum or a combination of 90°
and 45° elbows up to a maximum of 270°.
Z\x
For two-story applications, restops are required at each
oor level. If an offset is needed in the attic, additional pipe
and elbows will be required.
You may use a chase with a vent termination with exposed
pipe on the exterior of the house. See Installing Vent
System in a Chase below. If pipe is enclosed in chase, it
is not exposed.
It is very important that the venting system maintain its bal-
ance between the combustion air intake and the ue gas
exhaust. Certain limitations apply to vent congurations
and must be strictly followed.
A chase is a vertical boxlike structure built to enclose
venting that runs along the outside of a building. A chase
is required for such venting.

The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between the vertical and horizontal dimensions
of the vent system.
1. Determine the height of the center of the horizontal vent
pipe exiting through the outer wall. Using this dimen-
sion on the Sidewall Vent Graph below, locate the point
intersecting with the slanted graph line.
2. From the point of this intersection, draw a vertical line
to the bottom of the graph.
3. Select the indicated dimension, and position the re-
place in accordance with same.
Example: If the vertical dimension from the oor of the
replace is 11' (3.4 m) the horizontal run to the face of
the outer wall must not exceed 16' (4.9 m).

1. Rigid vent pipes and ttings have special twist-lock
connections. Assemble the desired combination of pipe
and elbows to the appliance adapter.
The female ends of the pipes
and ttings have three (3) locking lugs (indentations).
These lugs will slide straight into matching slots on
the male end of adjacent pipes and ttings. Push the
pipe sections together and twist one section clockwise
approximately one-quarter turn until the sections are
fully locked. Figure 20

The Vent Graph, showing the relationship between vertical
and horizontal side wall venting, will help to determine the
various dimensions allowable. Figure 18
Minimum clearance between vent pipes and combustible
materials is 3" on top and 1" from bottom and sides unless
otherwise noted (Exception: Outside wall with restop: 1"
all around pipes are allowed). If the vertical run is 7.5 feet
or more, from the oor of the replace, the clearance is 1"
on all sides of the horizontal run.
When vent termination exits through foundations less than
20" below siding outcrop, the vent pipe must be ush with
the siding.
It is best to locate the replace in such a way that minimizes
the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the ue collar of the replace (or the top of the
Transition Elbow) to the face of the nished outside wall
or the mounting ange of the termination.
• The maximum number of 90° elbows per side wall
installation is three (3). Figure 25
• If a 90° elbow is tted directly on the top of the replace,
the maximum horizontal vent run before the termination
or a vertical rise is 36” (914 mm). Figure 26
• If a 90° elbow is used in the horizontal vent run (level
height maintained) the horizontal vent length is reduced
by 36". Figure 23. This does not apply if the 90° elbows
are used to increase or redirect a vertical rise. Figure
27
According to the vent graph (Page 19) the
maximum horizontal vent length in a system with a 7.5'
vertical rise is 20’ (6 m) and if a 90° elbow is required in the
horizontal vent it must be reduced to 17' (5.2 m).
In Figures 27 and 28 dimension A plus B must not be
greater than 17' (5.2 m).

When it is not possible to meet the required vent terminal
clearances of 12" above grade level, a snorkel kit is recom-
mended. It allows installation depth down to 7" (178 mm)
below grade level. The 7" (178 mm) is measured from the
center of the horizontal vent pipe as it penetrates through
the wall.
If installing a snorkel, a minimum 24" vertical rise is nec-
essary. The maximum horizontal run with the 24” vertical
pipe is 36". This measurement is taken from the collar of
the replace (or transition elbow) to the face of the exterior
wall. Refer to the Sidewall Venting Graph for extended
horizontal run if the vertical exceeds 24".
1. Establish vent hole through the wall.
2.
Remove soil to a depth of approximately 16" below base
of snorkel. Install drain pipe. Install window well (not
supplied). Rell hole with 12" of coarse gravel leaving a
clearance of approximately 4" below snorkel. Figure 32
3. Install vent system.
4. Ensure a watertight seal is made around the vent pipe
coming through the wall.
5. Apply high temperature sealant caulking (supplied)
around the 5" and 8" snorkel collars.
6. Slide the snorkel into the vent pipes and secure to the

This gas replace has been approved for,
• Vertical installations up to 40' (12 m) in height. Up to
a 10' (3 m) horizontal vent run can be installed within
the vent system using a maximum of two 90° elbows.
Figure 35
Horizontal sections of this vent system require a
minimum of 3" clearances to combustibles at the top of
the ue and 1" clearance at the sides and bottom until the
ue penetrates the outside wall. A minimum 1" clearance
all around the ue is acceptable at this point of penetration.
Unless the vertical run is 7Z\x feet or higher form oor of
replace, the clearance for the horizontal run is 1" on all
sides.
Vertical sections of this vent system require a minimum of
1" clearance to combustibles on all sides of the pipe.
• Up to two 45° elbows may be used within the horizontal
run. For each 45° elbow used on the horizontal plane,
the maximum horizontal length must be reduced by 18"
(457 mm).

1. Determine the route your vertical venting will take. If
ceiling joist, roof rafters or other framing will obstruct
the venting system, consider an offset. Refer to Figure
32 to avoid cutting load bearing members.
Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shown on Page 19, Figure 18.
2. Set replace in desired location. Drop a plumb line down
from the ceiling to the position of the ue exit. Mark the
center point where the vent will penetrate the ceiling.
Drill a small locating hole at this point.
Drop a plumb line from the inside of the roof to the locat-
ing hole in the ceiling. Mark the center point where the
vent will penetrate the roof. Drill a small locating hole
at this point.

1. Cut a 10Z\x" (267 mm) square hole in the ceiling using
the locating hole as a center point The opening should
be framed to 10Z\x" x 10Z\x" (267 x 267 mm) inside
dimensions as shown in Figure 39 using framing lumber
the same size as the ceiling joist. If the area above the
ceiling is an insulated ceiling or a room, nail restop
from the top side. This prevents loose insulation from
falling into the required clearance space. Figure 39.
Otherwise, install restop below the framed hole. The
restop should be installed with no less than three (3)
nails per side. Figure 38 or 39.
2. Assemble the desired lengths of pipe and elbows nec-
essary to reach from the burner system ue up through
the restop. Be sure pipe and elbow connections are
fully twist-locked. Page 20, Figure 20.
3. Cut a hole in the roof using the locating hole as a center
point. (Cover any exposed open vent pipes before cut-
ting hole in roof). The 10Z\x" x 10Z\x" (267 x 267 mm)
hole must be measured on the horizontal. Actual length
may be larger depending on the pitch of the roof. There
must be a 1" minimum clearance from the vent pipe to
combustible materials. (Insulation should be considered
a combustible material). Frame the opening as shown
on Page 20, Figure 21.
4. Connect a section of pipe and extend up through the
hole.

If an offset is needed to avoid obstructions, you
must support the vent pipe every three (3) feet. Use wall
straps for this purpose. Refer to Page 26, Figure 37.
Whenever possible, use 45° elbows instead of 90° elbows.
The 45° elbow offers less restriction to the ow of the ue
gases and intake air.
5. Place the ashing over the pipe section(s) extending
through the roof. Secure the base of the ashing to
the roof and framing with roong nails. Be sure roong
material overlaps the top edge of the ashing. There
must be a 1" clearance from the vent pipe to combus-
tible materials.
6. Continue to add pipe sections until the height of the
vent cap meets the minimum requirements below.
You must increase vent height for steep roof
pitches. Nearby trees, adjoining roof lines, steep pitched
roofs, and other similar factors may cause poor draft or
down-drafting in high winds. Increasing the vent height
may solve this problem.
If the vent pipe passes through any occupied areas
above the rst oor, including storage spaces and closets,
you must enclose pipe. You may frame and sheetrock the
enclosure with standard construction material. Make sure
to meet the minimum allowable clearances to combustibles.
Do not ll any of the required clearance spaces with
insulation.

1. Flexible UL1777 listed venting may be used in any
venting application where rigid direct vent components
can be used.
Flex kits may not be modied. Flex
kits may be added to the end of a vent run made of rigid
vent sections using pipe manufacturer's approved ex
to pipe adapters. This may occur only if doing so does
not violate any of the venting length, height, routing,
horizontal to vertical ratio requirements or clearance
considerations detailed in this manual.

Use proper gas type for the replace you are installing.
If you have conicting gas type, do not install replace.
See dealer where you purchased the replace for proper
replace according to your gas type.
When using copper or ex connectors use only ttings
approved for gas connections. The gas control inlet is
3/8" NPT.
Before installing replace and burner system, make sure
you have the items listed below.
• External regulator • Tee joint
• Piping (check local codes) • Pipe wrench
• Sealant (resistant to propane/LP gas)
(supplied by installer)
• Test gauge connection*
• Sediment trap (recommended)
• Equipment shutoff valve*
• approved exible gas line with gas connector (if
allowed by local codes — not provided)
* A CSA design-certied equipment shutoff valve with
1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA design-certied equip-
ment shutoff valve from your dealer.
For propane/LP connections only, the installer must supply
an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas
pressure to between 11 and 13 inches of water. If you do
not reduce incoming gas pressure, burner system regula-
tor damage could occur. Install external regulator with the
vent pointing down as shown in Figure 50. Pointing the
vent down protects it from freezing rain or sleet.

The gas line connection may be made using 1/2"
rigid tubing or an approved ex connector. Since some
municipalities have additional local codes it is always best
to consult your local authorities and the current edition of
the National Fuel Gas Code ANSI.Z223.1, NFPA54. In
Canada CSA-B149 (1 or 2) Installation Code.
A listed manual shutoff valve must be installed upstream of
the appliance. Union tee and plugged 1/8" NPT pressure
tapping point should be installed upstream of the appli-
ance. Figure 51
Install main gas valve (equipment shutoff
valve) in an accessible location. The main gas valve is for
turning on or shutting off the gas to the replace.
Check your building codes for any special requirements for
locating equipment shutoff valve to replaces.
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess seal-
ant in pipe could result in clogged burner system valves.

We recommend that you install a sediment trap/drip leg
in supply line as shown in Figure 51. Locate sediment
trap/drip leg where it is within reach for cleaning. Install
in piping system between fuel supply and burner system.
Locate sediment trap/drip leg where trapped matter is not
likely to freeze. A sediment trap traps moisture and contami-
nants. This keeps them from going into the burner system
gas controls. If sediment trap/drip leg is not installed or is
installed wrong, burner system may not run properly.

1. Check gas type. The gas supply must be the same as
stated on the appliance’s rating decal. If the gas supply
is different from the replace, Do not install the
appliance. Contact your dealer immediately.
2. To ease installation, a 24" (610 mm) ex line with manual
shut-off valve has been provided with on this appliance.
Install and attach 1/2" gas line onto shut-off valve.
3. After completing gas line connection, purge air from
gas line and test all gas joints from the gas meter to the
replace for leaks. Use a solution of 50/50 water and
soap solution or a gas sniffer.
4. To check gas pressures at valve, turn captured screw
counter clockwise 2 or 3 turns and then place tubing
to pressure gauge over test point. Turn unit to high.
Figure 52. After taking pressure reading, be sure and
turn captured screw clockwise rmly to reseal. Do not
over torque. Check test points for gas leaks.

All System conguration/setup is done on the Command
Center.
When using On/Off wall switch, the switch must be
in the ON position to perform all conguration set ups at
the command center.
Choose the Mode That Best Suits Your Needs
The Signature Command System is designed to operate
in either Standing Pilot or Intermittent Pilot mode.
• The Standing Pilot Mode is best for colder climates
when the pilot must remain on continuously to prevent
condensation and ensure reliable operation.
• The Intermittent Pilot Mode is ideal for maximum ef-
ciency, igniting the pilot only when needed to start your
replace, lowering fuel consumption and reducing your
carbon footprint.
Either mode benets from the instantaneous battery back-
up, so you never have to worry about a power outage.
The Signature Command System comes stan-
dard in the Intermittent Pilot mode, so you must follow
the instructions below to switch to Standing Pilot Mode if
needed.
1. Holding the ON button on the Command Center while
turning on the master switch will toggle between stand-
ing pilot and intermittent pilot.
2. After the above operation, one beep (for standing pi-
lot) or two beeps (for intermittent pilot) will be given as
conrmation.

The ames from the burner should be visually checked
as soon as the heater is installed and periodically
during normal operation. In normal operation, at full
rate, and after operating for about 15 to 30 minutes,
the ame should be yellow and slightly taller than the
rear log. Figure 67
If the ame is blue and only in the center, turn off unit
and let cool. After unit is cool, remove logs and check to
make sure the back holes in the burner are not covered
with rock wool. If the back holes are clear, add more
rock wool to the center of the burner. Replace logs.
The type of installation, vent system
conguration, and wind effects may cause the ame
patterns to vary.
Keep the control compartment, logs, and burner areas
surrounding the logs clean by vacuuming or brushing at
least twice a year. Make sure the burner porting, pilot air
opening and burner air opening are free of obstructions
at all times.
The ames from the pilot should be visually checked as
soon as the heater is installed and periodically during
normal operation.
Figure 66. The
pilot ame has four distinct ames, one engulng the
thermopile, one engulng the sensor, and the other two
reaching to the main burners.
Inspect area around the injector. Remove any lint or foreign
material with a brush or vacuum.

The replace and venting system should be inspected
before initial use and at least annually by a qualied eld
service person. Inspect the external vent cap on a regular
basis to make sure that no debris is interfering with the
airow. Inspect entire venting system to ensure proper
function.
Thoroughly clean the inside of the glass door after using
the replace for ten hours. Periodically clean the glass
door as necessary.
When cleaning the glass, remember:
• Allow glass to
cool before removal.
• NEVER use abrasive materials.
• Keep children and pets a safe distance away.
• Never operate the replace without the glass door
properly secured.
• Never operate the replace if the glass is broken.
• Replace any glass that is chipped, cracked, or broken.
Replacement glass door assemblies MUST be supplied
by the replace manufacturer –
• Handle glass door with care to avoid striking or scratch-
ing it on hard objects.
To clean glass door, follow “Glass Removal” procedure
outlined in the Final Installation section. Film deposit on the
inside of the glass should be cleaned off using a nontoxic,
non-corrosive, non-abrasive, mild-cleaning solution. Simply
apply an adequate amount to the glass and wipe off with
a damp cloth. After all maintenance has been completed,
re-install glass door.
Leave logs installed in the replace for cleaning. Vacuum
surface of the logs with a brush attachment. If logs must be
removed for cleaning, handle carefully by holding gently at
each end. Gloves are recommended to prevent skin irrita-
tion from ceramic bers. If skin becomes irritated, wash
gently with soap and water. Vacuum surface of logs with
brush attachment or brush logs with a soft bristle brush
(i.e. clean, dry paintbrush). To place logs back in the re-
place, see “Log Placement” found in the Final Installation
section.
Replace or add rock wool as required following installa-
tion instructions in the Final Installation section of this
manual.
