SAFETY INFORMATION FOR USERS OF LP-GAS

Propane (LP-Gas) 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 precautions which can
protect both you and your family from an accident. Read them
carefully now, then review them point by point with the mem-

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

reghters 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 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 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 lter the odorant. Odorants

bers of your household. Someday, 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.

• Use your neighbor’s phone and call a trained LP-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 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.

• Learn to recognize the odor of LP-gas. Your local LP-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 LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.

• If you are not qualied, do not light pilot lights, perform

service, or make adjustments to appliances on the LP-Gas

system. If you are qualied, 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 lled and allowed
to set too long before relling. Cylinders and tanks which

SOME POINTS TO REMEMBER

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 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
orices. 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 com-

pletely empty or having it relled before it is completely

empty.

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 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!

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.

Pressure Testing of the Gas Supply System

1. To check the inlet pressure to the gas valve, a 1/8" (3 mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.

2. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).

3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff 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(14"w.c.)(3.5kPa)onthereplace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. (.872 kPa) 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. (2.614 kPa) Propane gas models will have a manifold

pressure approximately 7.0" w.c. (2.49 kPa) 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.

CLEARANCES FOR SINGLE FLUE

1. Pick a location on a wall with a clear space in the room.
In selecting a location for installation, it is necessary to
provide adequate accessibility clearances for servicing and
proper installation. Be sure to locate the unit close enough to a
115 VAC wall receptacle to properly power appliance.

2. When facing the front of the furnace, the minimum clearances
from casing to combustible construction are 0” (0 mm) on top,
0” (0 mm) on each side, recommend 4” (102 mm) for servicing

and 0” (0 mm) from the oor and 2” (51 mm) to rear wall for

servicing and installation.

3. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12” (305 mm).

HEATER INSTALLATION FOR SINGLE FLUE

The bottom of the exhaust vent terminal and the air intake shall
be located at least 12” (305 mm) above grade and must be vented
outside.

WARNING: The nearest point of the vent cap should be a

minimumhorizontaldistanceofsix(6)feet(1.83m)from

any pressure regulator. In case of regulator malfunction,

thesix(6)feet(1.83m)distancewillreducethechanceof

gas entering the vent cap.

Installation on Rugs and Tile

If this appliance is to be installed directly on carpeting, tile, or other

combustible material, other than wood ooring, the appliance shall

be installed on a metal or wood panel extending the full width and
depth of the appliance.

The base referred to above does not mean the re-proof base as

used on wood stoves. The protection is primarily for rugs that may
be extremely thick and light-color tile that can discolor.

Locating Wall Opening

The recommended location for this heater is on an outside wall
(the unit can be located on an inside wall but must not exceed 40’
(12.19 m) in exhaust vent length). Locate wall studs so that wall
vent opening will be located between wall studs. The wall opening
required for venting is a 1 7/8” (48 mm) minimum diameter
opening.

Refer to Pages 11 to 17 for positioning the heater on wall and for
locating gas line connection and vent opening. Heater can sit on

the oor.

Note: On horizontal runs, a P.V.C. support clamp needs to be in-

stalled every 3 feet. No “sags” in horizontal vent runs; water will
settle in the pipe.

When installing a single ue horizontal, the minimum vent length

protruding from the outside wall is 6” (15.2 cm). See Figure 23.

Minimum vent from the rear of the unit is 12”.

Note: Horizontal discharge 90° elbow must be pointed down­ward. See Figure 23. All horizontal runs require either a 1/4” per
foot rise to run condensation back to the heater, or a 1/4” per foot
downward slope to run condensation away from the heater.

Note: All PVC vent run piping can be purchased at a local hard­ware store. Schedule 40 PVC pipe should be used and cemented.
