General Information
• WARNING: If the fireplace contains glass doors,
In order to assure a safe and effective instal-
lation, only a qualified service person who is
familiar with the building codes and installation
techniques appropriate to your area may install
and service this appliance.
they must remain open at all times during the opera-
tion of the logset, allowing combustion air to circulate.
• In order to avoid any possible gas leaks, apply pipe
joint compound to all non-flared threaded connections
involved in this installation. For propane, the joint
compound must be resistant to the corrosive action of
propane.
• To check for leaks, always use a soapy water solu-
tion or a sniffer. Never test by using an open flame.
• The area around the gas logset must be free of all
combustible materials, especially gasoline or other
highly flammable, vapor producing liquids.
• Due to high temperatures, locate this logset away
from both high traffic areas and furniture and draper-
ies.
• Children and adults alike should be aware of the
high surface temperatures; to avoid the risk of burns
or ignition of clothing they should stay away.
• Do not touch any part of the logset other than the
controls while it is operating or immediately after you
turn it off.
• Supervise young children and pets carefully when
they are in the area where the logset is operating.
• Do not place clothing or other flammable material on
or near the logset.
•Make sure that any safety screen or guard, removed
during servicing, has been replaced before you use
the logset.
• It is imperative that you keep clear all burner areas,
control compartments and passageways for circulat-
ing air.
• Do not move the logset in any way that might dis-
lodge the logs from their fixed positions. If you bump
the logset check to see if you have dislodged any-
thing.
• Provide adequate clearances around air openings
into the combustion chamber and adequate acces-
sibility clearance for servicing and proper operation.
NEVER obstruct the front opening of the fireplace.
The Logsets have been designed and tested to oper-
ate safely when installed according to the installation
instructions contained in this manual. Read all instruc-
tions before starting the installation.
• For outdoor use only.
• The logset should be inspected before use and at
least annually thereafter. More frequent cleaning may
be necessary because of excessive lint from carpeting
or bedding material.
• In the United States, the installation and operation
must conform to local codes or, in the absence of local
codes, with the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, latest edition, CSA B149.1 Installation Code,
and with the National Electrical Code, ANSI/NFPA70
(latest edition).
• The gas logset and its individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 p.s.i.g. (3.5 kPa) The gas logset must be
isolated from the gas supply piping system by closing
its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pres-
sures equal to or less than 1/2 p.s.i.g. (3.5 kPa)
• Do not, under any circumstances, burn solid fuel
(wood, paper, coal) in the fireplace where you have
installed your logset. Do not use it for cooking. Put
nothing on top of the logs.
• The logset must be compatible with its fuel. Natural
gas requires different hardware than propane. Never
attempt to use natural gas with a propane logset or vice
versa.
• For a propane burning logset, the supply tank must
include a high to low gas pressure regulator. The tank
must be outdoors. Do not, under any circumstances,
locate supply tanks inside any structure.
• The fireplace must include a screen made of chain
mesh or a similar material. You must keep the screen
closed at all times during the operation of the logset; it
will protect you in the event of an explosion.

Leak Test Procedures
After connecting the gas supply, test for leaks. Use a 50/50 solution of liquid soap and water to test for
leaks at gas fitting and joints. Apply water/soap solution with brush only - do not over apply. NEVER test
with an open flame.
WARNING: DO NOT USE AN OPEN FLAME TO TEST FOR LEAKS!
NOTE: Always perform a leak test any time the appliance has been moved or disconnected from the
gas supply line.
Damper Stop Installation
The Damper Stop provided keeps your damper from
accidentally closing during operation of your set. This
Damper Stop must be installed onto your Damper at all
times. NOTE: The damper clamp is designed to hold
the damper plate open 3 inches. However, the damper
must be fully open when the log set is in operation.
Install the Damper Stop onto the edge of the damper plate.
Damper
Attach by securing the bolt provided to the damper plate
Plate
with an adjustable wrench. (Fig. 5)

If the Damper Stop does not fit, drill a 1/4” hole into the
damper plate and install an
Stop
anchor bolt with nut, at a 90 degree angle, so that the
damper plate will remain fully open.
DP104
Fig. 5 Attach damper clamp.
The proper finished installation of the Damper Stop is
shown in Figure 6. If the bolt fails to block the damper in
an open position, the damper should be removed from the
Chimney
chimney.
Clamp
To check your vent for proper drafting: Light a tightly
rolled newspaper on one end and place it at the inside
front edge of the fireplace. Observe the smoke and be
sure the vent is properly drawing it up the chimney. If
the smoke is drawn back into the room, extinguish the
Damper
flame and remove any obstruction until proper venting
is achieved. If that fails, check with a qualified chimney
sweep.

For Your Safety Read Before Lighting
WARNING: If you do not follow these directions exactly, a fire or explosion may result caus-
ing property damage, personal injury, or loss of life.
What To Do If You Smell Gas
• Do not try to light any appliance.
• Do not touch any electrical switch, do not use any phone in the immediate area.
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
Lighting Instructions
1. Turn the gas shut-off valve to OFF.
2. Wait five (5) minutes to clear out any gas. If you then smell gas STOP!
Follow the safety information above. If you don’t smell gas, go on to the
next step.
3. Light a match and lay it on top of the pan material, about 2” from the
end of the supply side of the pan. (Fig. 14)
4. Slowly turn the gas shut-off valve ON until the burner ignites. If the
burner doesn’t ignite within ten (10) seconds with the match burning,
turn the shut-off valve OFF and repeat steps 1 through 4 again.
LG175
Match
Fig. 14 Lighting the log set.
WARNING: Flame may flare up when ignited. Keep hands and face away from firebox.
Operation and Maintenance
To Adjust the Flame:
Adjust the flame to the desired level by rotating the gas valve counterclockwise to open or
clockwise
to close.
To Turn the Appliance Off:
Rotate the gas shut-off valve clockwise
to off.
Proper Maintenance:
• Keep the area around the log set clean and clear of debris.
• Occasionally, you may use a soft bristle brush to clean logs.
• Once every year, a qualified agency or certified chimney sweep should examine and clean the venting
system of the fireplace in which the log set is installed.
Appliance Break-in
During the 2-3 hour appliance break-in period, you may detect an odor from the appliance as the various
water-based paints used in the manufacture of this log set cure. This is a normal and temporary situation
that is not a cause for alarm.
To ensure proper curing of the logs:
1. Ignite a 2” flame and maintain it for 1/2 hour.
2. Burn the logs in consecutive 1/2 hour periods, raising the flame an additional 2” to full flame height for a
total of three hours.

Troubleshooting
Log Set Is Smoking/Sooting Excessively
It is natural and unavoidable for vented gas log sets to produce moderate levels of carbon (soot) where
flame contacts the logs. The logs can be cleaned using a soft-bristle brush. However, if soot is pro-
duced where there is no flame impingement, one of the following may be the cause:
Fireplace venting system not drafting properly: Make sure the damper is wide open at all times.
Preheat the flue in very cold weather by burning the log set at a very low level, then slowly increas-
ing the flame height over a matter of hours. Have the fireplace and the venting system professionally
cleaned.
Excessive flame impingement or blockage: Make sure there is proper spacing between the logs so
they are not smothering the flame. Rearrange the logs so they are touched less by the flames.
Excessive gas supply/pressure: Make sure the gas pressure coming into the fireplace does not ex-
ceed the maximum pressure allowed with this gas set (refer to tables on page 4). If you are using the
gas logs with a safety pilot kit, make sure you installed the correct orifice into the set.
Burner Is Excessively Noisy
Please note: The movement and combustion of gas will create low, unavoidable levels of noise.
Excessive gas pressure: Make sure the gas pressure coming into the fireplace does not exceed the
maximum pressure allowed with this gas set (refer to tables on page 4). If you are using the gas logs
with a safety pilot kit, make sure you installed the correct orifice into the set.
Passage of air/gas across irregular surfaces: There may be burrs, paint, or other blockages on the
burner bar ports. Check these ports and remove any blockage.
Gas Connector: Relieve any tight bends or kinks in the Flexible Gas Connector. Switch to a smooth
aluminum gas connector, which can be purchased at any hardware or home improvement store.
Burner Flame Is Too High (8-12” Above Top Logs) Or Too Low
(Below Top Logs)
Incorrect gas supply, pressure, or burner orifice used: Make sure the gas pressure coming into
the fireplace falls between the minimum and maximum pressures allowed with this gas set (refer to
tables on page 4). If you are using the gas logs with a safety pilot kit, make sure you installed the
correct orifice into the set.
Blocked ports (low flame only): Free the main burner orifice and burner bar ports of any burrs,
paint, or other blockage.
