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.
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
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

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.
Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to

be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
out of service for a time may develop internal rust which will
cause odor fade. If such conditions are suspected to exist,
a periodic sniff test of the gas is advisable. If you have any
question about the gas odor, call your LP-gas dealer. A
periodic sniff test of the LP-gas is a good safety measure
under any condition.

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

damper.
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.

Check all local codes for requirements, especially for the size
and type of gas supply line required.
Notice:
your local 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 instal-
lation or relocation.
Compounds used on threaded joints of gas piping shall be
lines must be 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. Appli-
ance 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.

authority having jurisdiction. The state of Massachusetts
three feet in length.
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.

During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain oils,
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.
