Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must nd out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors in
the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the

in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
Propane (LP-Gas) is a ammable gas which can cause res
and explosions. In its natural state, propane is odorless
and colorless. You may not know all the following safety
precautions which can protect both you and your family from
an accident. Read them carefully now, then review them point
by point with the members of your household. Someday when
there may not be a minute to lose, everyone's safety will depend
on knowing exactly what to do. If, after reading the following
information, you feel you still need more information, please
contact your gas supplier.

SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
SAFETY INFORMATION FOR USERS OF LP-GAS

28091-2-1212Page 6
When used without adequate combustion and ventilation
air, heater may give off CARBON MONOXIDE, an odorless,
poisonous gas.
Do not install heater until all necessary provisions are
made for combustion and ventilation air. Consult the
written instructions provided with the heater for information
concerning combustion and ventilation air. In the absence
of instructions, refer to the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation,
or applicable local codes.
This heater is equipped with a PILOT LIGHT SAFETY SYSTEM
designed to turn off the heater if not enough fresh air is
available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner and
control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO DEATH.
Early signs of carbon monoxide poisoning resemble the u,
with headache, dizziness and/or nausea. If you have these
signs, heater may not be working properly. Get fresh air at
once! Have heater serviced.
Some people – pregnant women, persons with heart or lung
disease, anemia, those under the inuence of alcohol, those
at high altitudes – are more affected by carbon monoxide
than others.
The pilot light safety system senses the depletion of oxygen
at its location. If this heater is installed in a structure having
a high vertical dimension, the possibility exists that the
oxygen supply at the higher levels will be less than that at
the heater. In this type of application, a fan to circulate the
structure air will minimize this effect. The use of this fan will
also improve the comfort level in the structure. When a fan
is used to circulate air, it should be located so that the air
ow is not directed at the burner.
DANGER: Indicates a hazardous situation which, if not avoided,
will result in death or serious injury.
WARNING: Indicates a hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION: Indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE: Addresses practices not related to personal injury.

appliance; possibly causing headaches or eye or lung irritation. This
is a normal and temporary occurrence.
The initial break-in operation should last 2-3 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 period 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

Water vapor is a by-product of gas combustion. An unvented room
heater produces approximately one (1) ounce (30ml) of water for

Unvented room heaters must be used as supplemental heat
(a room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application, including
ample combustion air and circulation air.

Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh
air for combustion and ventilation. However, in buildings of unusually
tight construction, you must provide additional fresh air.
Unusually tight construction is defined as construction
where:
a. Walls and ceilings exposed to the outside atmosphere have a
continuous water vapor retarder with a rating of one perm or
less with openings gasketed or sealed, and
b. Weatherstripping has been added on openable windows and
doors, and
c. Caulking or sealants are applied to areas such as joints around

You must secure the gas log heater to the replace oor. If
not, the entire unit may move when you adjust the controls.
Movement of unit may cause shifting of the gas logs which
leads to sooting and improper burning. Grate movement
could cause a gas leak.
Special care is required if you are installing the unit into a
sunken replace. You must raise the replace oor to allow
access to gas log controls. This will insure adequate air
ow and guard against sooting. Raise the replace oor
using noncombustible materials.
Assembly Procedure: (Figures 10 and 11)
1. Center the gas log unit in the fireplace or firebox. Make

codes allow copper tubing or galvanized.
Notice: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of
the unit. Where none exists, or where its size or location is not
adequate, contact your local authorized installer for installation or
relocation.

checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed ame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the gas
inlet. This should consist of a vertical length of pipe tee connected
into the gas line that is capped on the bottom in which condensation
and foreign particles may collect.

Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3.175mm)
N.P.T. plugged tapping, accessible for test gauge connection,
must be placed immediately upstream of the gas supply
connection to the appliance.
2. The appliance 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 psig (3.5 kPa).
3. The appliance 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
pressures equal to or less than 1/2 psig (3.5 kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will
result in a hazardous condition.

These chemicals are not harmful, 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 2-3 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.
