Minimum Depth of
Fireplace/Firebox
No Restriction 14" (356mm)
0" to 3" (76mm) 16" (406mm)
Greater than 3" (76mm) *
*Any barrier greater than 3" placed in front of the gas log set is not
recommended by the manufacturer.
NOTE: Non-combustible material such as refractory brick
may be used to line the oor of the replace in order to raise
the height of the gas log set in relation to a restrictive barrier.
If the unit is raised, the minimum height dimension listed
in the homeowner’s manual must be met or exceeded.
NOTE: If the log set is equipped with a remote receiver, a
restrictive barrier may reduce the battery life by increasing
the ambient temperature inside the replace. Placement of
the receiver outside of the replace will extend the battery
life. (MV models only)
Barriers such as the bottom of a glass door frame
placed in front of a gas log set can change the air
ow characteristics of the replace which in turn
can cause the unit to overheat and malfunction when
installed as a vented log set.

Gas Information
A. Gas Line Connection
NOTICE: A qualied gas appliance installer must connect
the heater to the gas supply. Consult all local codes.
IMPORTANT: Hold heater valve rmly with a wrench to
prevent movement when connecting to inlet pipe.
Always use an external regulator for all propane/LPG
heaters and high pressure one to two-pound systems
only, to reduce the supply tank pressure to a maximum of
13" w.c. This is in addition to the internal regulator in the
heater valve.
The heater gas inlet connection is a 3/8" NPT at the valve.
On all control type units, the inlet connection is on the right
side of unit. To connect from the opposite side, route the
pipe around the back portion of the unit.
When tightening up the joint to the valve, hold the valve
securely to prevent movement.
Test all gas joints from the gas meter to the heater valve for
leaks using a gas analyzer or soap and water solution after
completing connection. DO NOT USE AN OPEN FLAME.
Check the gas pressure with the appliance burning and
the control set to HIGH.
Use new black iron or steel pipe. Internally tinned
copper or copper tubing can be used per National
Fuel Code, section 2.6.3, providing gas meets
hydrogen sulde limits, and where permitted by local
codes. Gas piping system must be sized to provide
minimum inlet pressure (Listed on Data Plate) at the
maximum ow rate (BTU/hr). Undue pressure loss
will occur if the pipe is too small.
A 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 appliance.
WARNING
Connecting directly to an unregulated propane/
LPG tank can cause an explosion.
WARNING
CHECK GAS TYPE: The gas supply must be the
same as stated on the heater’s rating plate. If the
gas supply is different, DO NOT INSTALL THE
HEATER. Contact your dealer for the correct model.

PLACE THE DECORATIVE ROCK
The volcanic rocks are shipped with your log set. The vol-
canic rocks may be placed around the unit on the oor of
the rebox. Be sure to avoid any areas on the burner itself.
DO NOT sprinkle volcanic rocks on the logs,
around the pilot, nor near the burners. This
may cause sooting. Place volcanic rocks
only on the oor of the replace.
During initial operation of the new heater,
new burning logs and/or rock wool will give
off a paper burning smell and orange ames
will be present. Simply open the windows
for a few hours to vent the odor.
CAUTION
21
Outdoor Lifestyles • Lumonessen Owner’s /Installation Manual • 4629-900 Rev. A • 02/23
E. Flame Appearance
Flames from the pilot and burner should be visually
checked as soon as the heater is installed. In addition,
periodically check the ames visually during operation.
Check the Pilot Flame (refer to lighting instructions)
The pilot ame must always be present when the heater is
in operation. It should just touch the top of the thermocouple
tip. Refer to Figure 6.14 for correct pilot ame.
If the pilot ame does not touch the thermocouple, then
the main burner cannot function reliably. Figure 6.15 for
incorrect shape of pilot ame.
Figure 6.14 - Correct Appearance of Pilot Flame
Figure 6.15 - Incorrect Appearance of Pilot Flame
F. Operating Instructions
Avoid any drafts that alter burner ame patterns. Do
not allow fans to blow directly into the replace. Do not
place a blower inside the burn area of the rebox. Ceiling
fans may create drafts that alter ame patterns. Sooting
and improper burning will result.
During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain oils,
lms or bonding agents. These chemicals are not harm-
ful, but may produce annoying smoke and smells as they
are burned off during the initial operation of the appliance,
possibly causing headaches or eye or lung irritation. This
is a normal and temporary occurrence.
The initial break-in operation should last four hours with the
burner at the highest setting. Provide maximum ventilation
by opening windows or doors to allow odors to dissipate.
Any odors remaining after this initial break-in will be slight
and will disappear with continued use.
This appliance must not be used with glass doors in the
closed position. This can lead to pilot outages and severe
sooting outside the replace.
CAUTION: After a 15 minute pre-heat period, observe all
yellow ames to ensure there is no impingement with any
log. If any yellow ame is contacting any log, turn off log
set and allow to cool. Remove all logs and carefully rein-
stall following log placement instructions precisely. Relight
burner and check again for impingement of any ame on
log. If ame impingement cannot be eliminated, contact
your installer or dealer for assistance. Flame impingement
on logs may create soot and possible property damage.
