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 precau
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
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!
• 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.
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 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
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 read
ing the following information, you feel you still need more
information, please contact your gas supplier.
• 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.
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.
-
SOME POINTS TO REMEMBER
• 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 performing 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
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 under
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.

Figure 5
Installing the 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 millivolt gas controls are 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.
When using copper or flex connector use only approved fittings.
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 Pressures
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) at the valve outlet
with the inlet pressure to the valve from a minimum of 4.5" w.c.
(1.120kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa). Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8" w.c.
(2.68kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa).
