WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance
connected to the venting system being placed into operation
could result in carbon monoxide poisoning or death.
The following steps shall be followed for each appliance
connected to the venting system being placed into operation,
while all other appliances connected to the venting system
are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and horizontal
pitch, as required in the National Fuel Gas Code ANSI
Z223.1/NFPA 54 or the National Gas and Propane
Installation Code CSA B149.1 and these instructions.
Determine that there is no blockage or restriction,
leakage, corrosion and other deciencies which could
cause an unsafe condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which
the appliance(s) connected to the venting system are
located and other spaces of the building.
4. Close replace dampers.
5. Turn on clothes dryers and any appliance not connected
to the venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they are
operating at maximum speed. Do not operate a summer
exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the thermostat
so appliance is operating continuously.
7. Test for spillage from draft hood equipped appliances

SAFETY INFORMATION FOR USERS OF PROPANE GAS
Propane 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 precau-
tions which can protect both you and your family from an ac-
cident. 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 informa-
tion, 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, 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.
• 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 reghters declare them to be safe.
• Use your neighbor's phone and call a trained Propane Gas
service person and the re 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 reghters 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 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 Propane Gas is colorless, and it can fade
under some circumstances. For example, if there is an under-
ground leak, the movement of the gas through soil can lter the
odorant. Odorants in Propane 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.
Propane 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 Propane Gas. Your lo-
cal Propane Gas Dealer can give you a "Scratch and Sniff"
pamphlet. Use it to nd 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 qualied, do not light pilot lights, perform
service, or make adjustments to appliances on the Propane
Gas system. If you are qualied, 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 lled and allowed to
set too long before relling. 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 ex-
ist, a periodic sniff test of the gas is advisable. If you have
any question about the gas odor, call your Propane Gas
Dealer. A periodic sniff 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. Then 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 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 orices. If this oc-
curs, 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 relled
before it is completely empty.

Each appliance should have its own manual gas shut-off valve.
A manual main gas shut-off valve 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 liqueed 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 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!
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 ex connector use only approved ttings.
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 (3.5 kPa).
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 (3.5 kPa).
CAUTION
If one of the procedures results in pressures in excess of
1/2 psig (14" w.c.) (3.5 kPa) on the stove 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. (.871 kPa) for maximum input or
1.7" w.c. (.423 kPa) for minimum input at the valve outlet with the inlet
pressure to the valve from a minimum of 5.0" w.c. (1.245 kPa) for the
purpose of input adjustment to a maximum of 10.5" w.c. (2.615 kPa).
Propane Gas models will have a manifold pressure approximately
10.0" w.c. (2.49 kPa) for maximum input or 5.9" w.c. (1.469 kPa)
for minimum input at the valve outlet with the inlet pressure to the
valve from a minimum of 11.0" w.c. (2.739 kPa) for the purpose of
input adjustment to a maximum of 13.0" w.c. (3.237 kPa).
A 1/8" (3 mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the outlet side of the gas control.

In selecting a location for installation, it is necessary to provide ad-
equate accessibility clearances for servicing and proper operation.
