SAFETY INFORMATION
Due to high temperatures, the appliance should be
located out of traffic and away from furniture and
draperies.
Children and adults should be alerted to the hazards of
high surface temperatures and should stay away to avoid
burns or clothing ignition.
Young children should be carefully supervised when they
are in the same room as the appliance.
Clothing or other flammable material should not be
placed on or near the appliance.
The glass and front frames must be put back in place
prior to operating the appliance if they have been
removed for servicing or cleaning.
Never operate with broken or damaged window glass.
This appliance should be installed and repaired by a
qualified service person.
The appliance should be inspected before use and at least
annually by a professional service person. More frequent
cleaning may be required due to excessive lint from
carpeting, bedding material, etc. It is imperative that
control compartments, burners and circulating air
passageways of the appliance are kept clean.
Keep curtains, clothing, furniture and other flammable
materials a safe distance from all parts of the appliance.
When operating your new furnace for the first time, some vapors may be released which may cause a slight odor and could possibly set off any smoke
detection alarms in the immediate vicinity. These vapors are quite normal on new appliances. They are totally harmless and will disappear after a few
hours use.
Keep the appliance area well clear and free from
combustible materials, gasoline and other flammable
vapors and liquids.
If any changes are made to the room construction in the
vicinity of the appliance after installation (e.g. additional
mantle etc.) make sure that the changes conform to the
installation requirements in this manual.
Never attempt to burn paper or any other material in the
appliance.
Keep the base of the appliance clear to prevent
obstruction of air flow to the appliance.
This appliance must be properly connected to a venting
system. Models 737AN and 737AP are equipped with a
vent safety shutoff system. Operating when not connected
to a properly installed and maintained venting system or
tampering with the shutoff system on models 737AN or
737AP can result in carbon monoxide (CO) poisoning
and possible death.
The venting system should be checked periodically.
Recent trends in home improvement and new tighter
construction techniques have contributed to problems
with venting. If you suspect that your appliance is not
venting properly, do not operate. Seek expert advice.
Do not use this appliance if any part has been under
water. Immediately call a qualified service technician to
inspect the appliance and to replace any part of the
control system and any gas control which has been under
water.

#776CFK Circulating fan kit
designed to boost the natural convection process
through the heater. This may be a desirable feature
dependent on the fireplace location and room
layout. The circulating fan may be installed during
initial appliance installation or as a retrofit at a later
date. Full installation and operating instructions are
included with the kit.
#770ZCK Zero clearance kit
constructed of combustible material. The kit must
be used in this form of enclosure. Enclosure framing
dimensions suitable for the kit are shown in section
2 of this manual. This zero clearance kit has been
designed to act as a “rough in” box with the
appliance model 737 purchased and/or fitted after
the walls of the enclosure and the hearth have been
fitted. Full installation instructions are included with
the kit.

national, state provincial or territorial building code
recognized by the authority having jurisdiction, or in
the absence of such a code, in accordance with the

fireplace checked for soundness before installation
of the appliance. The liner must be a type approved
by the enforcing authority and installed in
accordance with the manufacturer's instructions.
combustible floor. The floor must be sufficiently flat
and level to support the appliance satisfactorily.
Some fireplace constructions have a well in the
floor at the back that may need to be filled in. In the
USA it is mandatory that a hard surfaced noncombustible hearth area must be maintained at
least 16" in front of the fireplace. This may be
finished in brick, ceramic tile, marble
the hearth slightly will help to minimize dust and lint
accumulation under the unit.
In Canada, though not mandatory, we recommend
that carpet, soft vinyl or other combustible floor
coverings are kept at least 16” from the front of the
furnace since these types of materials may be
affected by the high radiant heat output from this
appliance.
The minimum clearances from any combustible
constructions at the front of the appliance are
shown in fig.1b. These front clearances apply for
all installations.
2.2
Enclosures constructed with combustible materials
#770ZCK Zero clearance kit must be installed
where the furnace is intended to be in an enclosure
made with wood studding or other combustible
materials.
The enclosure framing requirements are shown in
figures 1c through 1f.
Note that in Canada, though not mandatory, we
recommend that carpet, soft vinyl or other
combustible floor coverings are kept at least 16”
from the front of the furnace since these types of
materials may be affected by the high radiant heat
output from this appliance.
