SAFETY INFORMATION FOR USERS OF LP-GAS

LP-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 precautions

which can protect both you and your family from an accident.

Read them carefully now, then review them point by point with the

members of your household. Someday, there may not be a

minute to lose, everyone’s safety will depend on knowing ex-

actly what to do. If, after reading the following information, you

feel you still need more information, please contact your gas

supplier.

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.

• 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 es-

caped 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.

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 odor-

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 nd out what the propane odor smells like. If you sus-

pect 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

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

completely empty or having it relled before it is

completely empty.

Cleaning the Glass Door

WARNING

Do not operated this appliance without the glass door in

place. Do not operate if the glass front is broken or dam-

aged. Do not use the glass door if the gasket is missing or

damaged.

Over time, the glass door will need to be cleaned. For best results,

it is recommended to clean the glass with high quality replace

glass cleaner.

If the glass needs to be replaced, contact a qualied service per-

son. Only glass approved by Empire Comfort Systems Inc. can be

used, any other product will void the warranty.

To clean inside the glass door, the door will need to be removed.

CAUTION

Do not attempt to clean the glass when it is hot. Do not

strike or hit the glass.

CAUTION

Be certain the glass is cool before handling.

1. For replaces equipped with the louvered front panel, remove

the lower louvered panel by lifting up, then pulling out. For

replaces equipped with the louverless surround, remove the

surround by lifting up, then pulling out.

31794-1-0115 Page 17

2. Release the two door latches on the underside of the rebox.

3. Hold the bottom of the glass door and lift, keeping a rm grip

on the door.

4. Keep the glass angled to the rebox, then gently pull the glass

door away from the heater. DO NOT damage or remove the

gasket from the door.

Service and Maintenance

Although most service should be conducted by a qualied service

person, there are several things that can be checked to ensure

safe and comfortable operation.

Keep the area surrounding the replace free from any types of

combustible materials. The lter should be checked and cleaned

on a monthly basis. All other maintenance should be conducted

by a qualied service person.

Circulating Air Blower

The circulating air blower should be checked and cleaned annu-

ally by a qualied service person to ensure that your appliance is

operating efciently. Any dirt or lint can affect the operation of the

blower.

Heat Exchanger

The heat exchanger is located on the backside of the replace.

The heat exchanger should be inspected and cleaned annually by

a qualied service person.

Porcelain Liners

Over time a lm may form on the porcelain liners. It is recommend-

ed to clean the liners with a high quality replace glass cleaner. To

clean the liners, the glass door will need to be removed. Follow the

directions for removing the glass door on pages 16 and 17.

If the liners need to be replaced, contact a qualied service person.

Only liners provided by Empire Comfort Systems can be used, any

substitute will void the warranty.

Filter

The lter is located on the inside of the lower louver panel (on

replaces equipped with FIK, FFK or FWK Surrounds) or on the

inside bottom ange of the surround (FHK Surrounds).

To clean the lter on replaces equipped with the lower louver

panel, simply remove the panel and disengage the lter rod from

its retaining holes.

For replaces equipped with louverless FHK surrounds, the en-

tire surround must be removed from the replace. This is accom-

plished by lifting and removing the surround from the support

bracket hooks. Remove the lter retainers and lters from the in-

side bottom ange by removing the screw holding the lter retainer

in place.

The lters may be rinsed with water or blown clean with com-

pressed air. Allow the lters to dry completely before reinstalling

them.
