Propane is a flammable gas which can cause fires 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.
PROPANE GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas
because of the odorant put in the Propane Gas. That’s your
signal to go into immediate action!
• Do not operate electric switches, light matches, or use your
phone. Do not do anything that could ignite the gas.
• IMMEDIATELY get everyone out of the building, vehicle,
trailer, or area.
• Close all gas tank or cylinder supply valves.
• Propane gas is heavier than air and may settle in low areas
such as basements. When you have reason to suspect a gas
leak, keep out of basements and other low areas. Stay out
until firefighters declare them to be safe.
• Use your neighbor’s phone and call a trained propane gas
service person and the fire department. Even though you
may not continue to smell gas, do not turn on the gas again.
Do not re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for
escaped gas. Have them air out the area before you return.
Properly trained propane gas service people should repair
the leak, then check and relight the gas appliance for you.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can aect 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 propane gas is colorless, and it can fade under
some circumstances. For example, if there is an underground
leak, the movement of the gas through soil can filter the odorant.
Odorants in propane gas are also 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 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.
SAFETY INFORMATION FOR USERS OF PROPANE GAS
Propane gas may stratify in a closed area, and the odor intensity
could vary at dierent 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.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of propane gas. Your local
propane gas dealer can give you a “Scratch and Sni”
pamphlet. Use it to find out what the propane odor smells
like. If you suspect that your propane gas has a weak or
abnormal odor, call your propane gas dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the
propane gas system. If you are qualified, consciously think
about the odor of propane gas prior to and while lighting
pilot lights or performing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the propane gas odor. Do not try
to light pilot lights, perform service, or make adjustments
in an area where the conditions are such that you may not
detect the odor if there has been a leak of propane gas.
• Odor fade, due to oxidation by rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks
or cylinders are placed in service. Odor fade can occur
in new tanks, or reinstalled old tanks, if they are filled
and allowed to set too long before refilling. Cylinders
and tanks which have been out of service for a time may
develop internal rust which will cause odor fade. If such
conditions are suspected to exist, a periodic sni test of
the gas is advisable. If you have any question about the
gas odor, call your propane gas dealer. A periodic sni
test of the propane gas is a good safety measure under
any condition.
• If, at any time, you do not smell the propane gas odorant
and you think you should, assume you have a leak. Take
the same immediate action recommended above for the
occasion when you do detect the odorized propane gas.
• If you experience a complete “gas out,” (the container
is under no vapor pressure), turn the tank valve o
immediately. If the container valve is left on, the
container may draw in some air through openings such
as pilot light orifices. If this occurs, some new internal
rusting could occur. If the valve is left open, then
treat the container as a new tank. Always be sure your
container is under vapor pressure by turning it o at the
container before it goes completely empty or having it
refilled before it is completely empty.

Vertical Sidewall Installations
Important! Minimum clearance between vent pipes and
combustible materials is 3 inch (76 mm) on top, and 1 inch (25
mm) on bottom and sides.
Important! When vent termination exits through foundation less
than 20 inch (508 mm) below siding outcrop, the vent pipe must
extend outward so that the horizontal vent termination is located
flush to, or beyond the outcrop siding.
Information on Various Venting Routes and Components
Important! It is always best to locate the fireplace in such a way
that minimizes the number of osets and horizontal vent length.
Since it is very important that the venting system maintain its
balance between the combustion air intake and the flue gas
exhaust, certain limitations as to vent configurations apply and
must be strictly adhered to.

The gas pipeline can be brought in through the right side of the
fireplace. Consult the current National Fuel Gas Code, ANSI
Z223.1 CAN/CGA-B149 (.1 or .2) installation code.
NOTICE: Never use plastic pipe. Check to confirm whether 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
The use of the following gas connectors is recommended:
• ANSI Z21.24 Appliance Connectors of Corrugated Metal
Tubing and Fittings.
• ANSI Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The Commonwealth of Massachusetts requires
that a flexible appliance connector cannot exceed three feet in
length.

GAS SUPPLY
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 leg 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.
Installing a New Main Gas Shut-O Valve (Check Local Code)
Each fireplace should have its own manual gas shut-o valve. A
manual main gas shut-o valve should be located in the vicinity
of the fireplace. Where none exists, or where its size or location
is not adequate, contact your local authorized installer for
installation or relocation.
WARNING
Never pressure test with fireplace connected; control valve will
sustain damage! To prevent damage or injury, the fireplace and
its individual shut-o valve must be disconnected from supply
piping system during any pressure testing of that system at test
pressures in excess of 1/2 psig (3.5 kPa).
NOTICE: The gas control is equipped with a captured screw
type pressure test point, therefore it is not necessary to provide
a 1/8 inch test point up stream of the control.
When using copper or flex connector use only approved
fittings. The fireplace and its individual shut o valve must be
disconnected from supply piping system during any pressure
testing of that system at test pressures in excess of 1/2 psig (3.5
kPa).
The fireplace must be isolated from the gas supply piping
system by closing its individual manual shut o 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 (14in w.c.) (3.5 kPa) on the fireplace gas valve, it will
result in a hazardous condition.
WARNING
This step is to be carried out first before further installation has
takenplace, failure todo so will result inthe appliancehaving to be
