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
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!
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
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell
the odor of the chemical stench 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 odor
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.
ant. 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.
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
12427-6-0707
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.
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.
A periodic sniff test of the LP-gas is a good safety

Ventilation and Combustion Air
WARNING: Danger of property damage, bodily injury or death,
this furnace and any other fuel burning appliance must be provided
with enough fresh air for proper combustion and ventilation of
flue gases. Most homes will require that outside air be supplied.
Do not draw air from a corrosive environment such as a workshop
or laundry room.
The requirements for providing air for combustion and ventilation are
listed in the National Fuel Gas Codes NFPA 54/ANSI Z223.1 (in Canada
- CAN/CGA B149).
Note: Air requirements for operation of exhaust fans, kitchen ventilation
systems, clothes dryers, fireplace and any other fuel burning or ventilating
equipment used in the space must be considered in determining combustion
air requirements.
Ventilation Air Openings and Ducts
In determining the free area needed consideration must be given to the
blocking effect of louvers, grills or screens protecting openings.
— If a screen is used to cover openings it must not be smaller than 1/4"
mesh.
— Use the free area of a louver or grill to determine the size opening
required to provide the free area specified. If the free area is not
known assume a 20% free area for wood and a 60% free area for a
metal louver or grill.
— Ducts must have the same cross sectional area as the free area of the
openings to which they connect.
— The minimum dimension of air ducts must not be less than 3
inches.
Installation in an Unconfined Space
An unconfined space is an area including all rooms not separated by
doors with a volume greater than 50 cubic feet per 1,000 Btuh of the
combined total input rates of all appliances which draw combustion air
from that space. For example, a space including a water heater rated at
40,000 Btuh input and a furnace rated at 40,000 Btuh requires a volume of
4,000 cubic feet (50 x (40 + 40) = 4,000) to be considered as unconfined.
If the space has an 8 ft. ceiling, the floor area of the space must be 500
sq. ft. In general, particularly in older homes, a furnace installed in an
unconfined space will not require outside air for combustion. However
in a "tight" newly constructed home, outside air may be necessary to
insure adequate combustion.
Installation in a Confined Space
A confined space is an area with volume less than 50 cubic feet per 1,000
Btuh of the combined input rates of all appliances drawing combustion
air from that space. Small areas such as equipment rooms are confined
spaces. Furnaces installed in a confined space which supply heated air
to areas outside the space must draw return air from outside the space
through tightly sealed return air ducts. A confined space must have 2
openings into the space for combustion air. One opening must be within
12 inches of the ceiling and the other must be within 12 inches of the
floor. The required sizing of these openings is determined by whether
inside or outside air is used to support combustion, the method by which
the air is brought to the space (vertical or horizontal duct) and by the total
input rate of all appliances in the space. See Figure 1.
All Air From Inside — Confined Space
If combustion air is taken from the heated space the 2 openings must
each have a free area of at least one square inch per 1,000 Btuh of total
input of all appliances in the confined space but not less than 100 square
inches (645cm2) of free area.
For example: for a 40,000 Btuh furnace only in the confined space each
opening must be 100 square inches (645cm2) each of free area.
Figure 1
Outdoor Air
Outlet and inlet air can be brought into the confined space via openings
into a ventilated attic and ventilated crawl space.
Figure 2
Confined Space
Outdoor Air Using Vertical or Horizontal Ducts
If combustion air is taken from outdoors through vertical ducts, the
openings and ducts must have a minimum free area of one square inch
(6.5cm2) per 4,000 Btuh of total appliance input. In installations drawing
combustion air from a ventilated attic both air ducts must extend above
the attic insulation.
WARNING: Combustion air must not be drawn from a heated space
which includes exhaust fans, fireplaces or other devices that may
produce a negative pressure in the space.

Figure 3
If combustion air is taken from outdoors through horizontal ducts the
openings and ducts must have a minimum free area of one square inch
(6.5cm2) per 2,000 Btuh of total appliance input.
