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 odorant.
Odorants in LP-Gas also are subject to oxidation. This fading can

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 re­enter 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.

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

R-1842 Page 3

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
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.

GENERAL INSTRUCTIONS

Follow a few simple rules and your Empire furnace will give you
years of trouble-free heating. When your furnace is ready for
installation, operation or repair here are a few DO's and DON'T's.

DON'T install the furnace yourself if you are not qualified in
working with gas piping, chimneys, flue pipes, and venting. Gas
appliances and gas piping should be installed or repaired only by
a qualified serviceman.

DO get a qualified installing agency to install your furnace. By the
term "qualified installing agency" is meant any individual, firm,
corporation or company which either in person or through a
representative is engaged in and is responsible for the installation
or replacement of gas piping on the outlet side of the meter, or of
the service regulator when a meter is not provided; or the
connection, installation or repair of gas appliances, who is
experienced in such work, familiar with all precautions required;
and has complied with all the requirements of the authority
having jurisdiction.

The installation must conform with local codes, or in the absence
of local codes, with the National Fuel Gas Code ANSI Z223.1.

*Available from the American National Standards Institute, Inc., 11 West 42nd
St., New York, N.Y. 10036.

DO consult your dealer and local gas supplier about qualified
installers and servicemen.

DO refer to your Empire Installer and Serviceman's Manual so
that you can make sure that all installation and service work was
done properly. You bought the best furnace, now make sure you
get the best service.

DO make sure your venting system and flue pipe were installed
as outlined in your Empire Installer and Serviceman's Manual.

DO see "Using Your Furnace" before you try to light the pilot or
turn your furnace on.

DO see "Using Your Furnace" for instructions on how to set the
register temperature control when children are present.

CAUTION

Floor register becomes hot when operating and can cause burns.
Keep children off!

DON'T adjust or repair the combination valve, and don't take it
apart.

DON'T try to make any repairs except the ones listed for you to
do in Service Checks.

DID YOU GET EVERYTHING?

After you have unpacked your Empire furnace, you should make
certain everything is in order. For example, did you receive the
model furnace you ordered? Is it the model for the type of gas
(Natural or Propane) you want? Did you get all of the parts you
are supposed to have? Look at picture A. It will tell you where
your furnace identification plate is. The plate has stamped on it
the model and serial number of the furnace you received. It also
tells if your furnace is supposed to use natural (NAT) or propane
(LP) gas. See if the serial number on your furnace is the same as
the number on the WARRANTY CARD. Be sure your dealer fills
out the WARRANTY CARD, then MAIL the purchaser's report

(bottom part) to us. Look at Picture A and also the list below to
see if you have received everything on the list. If anything is
missing or broken, or if the model or serial numbers are not right,
or if the furnace is for natural and you have propane (or the other
way around), contact your dealer or Empire Comfort Systems,
Inc.

HOW YOUR FURNACE WORKS

HEATING

Your Empire furnace uses air from two places; air from outside
the living area, and air from inside the living area. The air from
outside the living area is mixed with gas and burned inside a
chamber in your furnace. The burned gas and air is exhausted
through a flue pipe to the outside air again. This exhaust should
not be permitted to enter the living area.

Burning gas inside the furnace chamber makes the chamber hot.
Cool air from inside the living area is drawn into the furnace and
flows past the outside of the hot chamber. The chamber makes
this air hot and this hot air flows out of the furnace and back into
the living area. When enough air in the living area has been
heated, the thermostat turns the furnace off automatically.

Picture B shows the flow of air inside and air outside the living
area. You can see that the air inside is not mixed with air outside
the living area. The furnace does not burn air that is within your
living area, and burned air or exhaust should not enter the living
area.
