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
Propane (LP-Gas) 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.
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area.
Do that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-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 LP-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 LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
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 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
movement of the gas through soil can filter the odorant. Odorants
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.
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the odor
of LP-Gas prior to and while lighting pilot lights or perform-
ing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-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 LP-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 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.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is un-
der no vapor pressure), turn the tank valve off 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 off
at the container before it goes completely empty or having
it refilled before it is completely empty.

it is always best to consult your local authority and installation
code.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal
Tubing and Fittings
— ANS 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 state of Massachusetts requires that a
flexible appliance connector cannot exceed three feet in length.
Figure 1
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.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas 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 flame 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!
NOTE: The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8"
test point up stream of the control.
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.
When using copper or flex connector use only approved fittings.
Always provide a union so that gas line can be easily disconnected
for burner servicing.
The appliance and it's individual shut off valve must be disconnected
from supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5kPa).
The appliance must be isolated from the gas supply piping system
by closing its individual manual shut off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 psig (3.5kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the fireplace gas valve, it will
result in a hazardous condition.
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5" w.c. (.871kPa) for maximum input
or 1.7" w.c. (.423kPa) for minimum input at the valve outlet
with the inlet pressure to the valve from a minimum of 5.0" w.c.
(1.245kPa) for the purpose of input adjustment to a maximum of
10.5" (2.615kPa) w.c. Propane gas models will have a manifold
pressure approximately 10.0"w.c. (2.49kPa) for maximum input
or 5.9" w.c. (1.469kPa) for minimum input at the valve outlet
with the inlet pressure to the valve from a minimum of 11.0" w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of
13.0" w.c. (3.237kPa).
A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the outlet side of the gas control.
