• Any safety screen or guard removed for servicing the heater
must be replaced prior to operating the heater.
• Installation and repair should be done by a qualified service
person. The heater should be inspected before use and at
least annually by a professional service person. More fre-
quent cleaning may be required due to excessive lint from
carpeting, bedding material, etc. It is important that control
compartments, burners and circulating air passageways of
the heater be kept clean.
• Allow the heater to cool before servicing. Always shut off the
gas to the heater while performing service work.

absence of local codes with the National Fuel Gas Code,
ANSI Z223.1/NFPA 54-latest edition.

-
nected from the gas supply piping system while performing
any tests of the gas supply piping system at pressures in
excess of 1/2 psig.
• The heater must be isolated from the gas supply piping

• Input ratings are shown in BTU per hour and are for elevations
up to 4,500 feet. Do not install this heater at an elevation
above 4,500 feet if the gas supply has not been derated for
that elevation. Consult your local gas supplier. (For operation
at elevations above 4,500 feet, equipment ratings shall be
reduced at the rate of 4 percent for each 1,000 feet above
4,500 feet before selecting appropriately sized equipment).
When installing any vent-free appliance at elevations above
4500 feet, nuisance pilot outages may occur.
• Ensure that the heater is clean when operating. Excessive
dust accumulation on the burner will increase the amount
of carbon monoxide formation and could lead to carbon
monoxide poisoning and/or death.
• This appliance is intended for supplemental heating. If the
appliance is used in a room as the sole source of heat, then
condensation may occur on colder surfaces within the room.
• Carbon monoxide poisoning – early signs of carbon monox-
ide poisoning resemble the flu with headaches, dizziness,
or nausea. If you have these signs, get fresh air at once!
Turn off the gas supply to the appliance and have the heater
inspected by a qualified service technician. Some people
are more affected by carbon monoxide than others. These
include pregnant women, people with heart or lung disease
or anemia, those under the influence of alcohol, and those
at high altitudes.

room.
