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.
Readthemcarefullynow,thenreviewthempointbypointwiththe
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
slightestgasodor.Ifyoudetectanyodor,treatitasaseriousleak.
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.

After the replace is turned off, the blower will continue to operate,
automatically adjusting its speed as the replace cools. Once the
replace cools sufciently the blower will turn off.
Note: When the replace is turned off, the blower speed will
not be displayed while it is running.
HumidierOperation
The Mantis Power-Vent High-Efciency Fireplace has an automat-
ic humidier designed into the replace. As the replace operates,
condensate is created and collected inside the replace. The col-
lected condensate is then transferred to a pan on top of the re-
place where it evaporates into the air stream. The humidier does
not operate with every cycle.
While the condensate is being transferred to the pan, it is normal
to hear a slight hissing sound. The “AUX” symbol will be displayed
while the condensate is being transferred.

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.

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.
