VENTING
This heater is a vented appliance and must be
connectedtoachimney/flueinaccordancewith
the installation codes.
Note: The rear pedestal cover plate is
only required when outside air is
being used. If using room air for
combustion,removethisplatefrom
the back of the pedestal.
For your safety this heater is equipped with a
vent safety switch designed to sense incorrect
ventingandreactbyshuttingdownthegassup-
ply. This thermally actuated switch is located
within the draft hood and will detect either a
blocked chimney or backdraft condition where
the chimney flow has reversed. If this switch
shuts the unit down, it indicates a drafting
problem that must be identified and rectified
without delay - the thermally activated switch
must neverbe bypassedordisconnectedasa
hazardous or deadly condition can result.
Venting Requirements
A four inch diameter vent is required. B-Vent,
Class A or Masonry with an approved liner
are all acceptable. For cosmetic or aesthetic
purposes 6" outer vent can be used as long as
an approved inner vent is installed. Fasten but
donot penetrate theinner sleeve ofthe B-Vent
when tightening the screw.
Followallventingmanufacturer’srequirements
and local building codes. In cold climates,
we recommend the use of insulated B-vent,
chase, and liners. For altitudes above 2000
ft. we recommend that a minimum flue height
of 12 ft. is used.
Flue Mounting Bracket
Attach the flue mounting bracket with the en-
closed screw as shown in the diagram.
DRAFT HOOD
This heater has a draft hood built in. It must not
be altered, obstructed, or blocked in any way,
and the unit must be installed so that the draft
hoodis in thesame atmospheric pressurezone
as the combustion air inlet to the burner. This
heater must be properly connected to a vent-
ing system. This heater is equipped with a vent
safety shutoff system.
WARNING: Operation of this heater when
not connected to a properly installed and
maintained venting system or tampering
with the vent safety shutoff system can
result in carbon monoxide (CO) poisoning
and possible death.
HIGH ELEVATION
TheU38-1(with40,000BTUrating) isapproved
in Canada for altitude 2000 ft. to 4500 ft. (CAN/
CGA-2.17-M91) with the orifice kit (Part # 591-

10 minutes. If the heater turns off because
ofthisduringthespillagetest,checkforthe
cause of the lack of draft.
TEST FOR FLUE
SPILLAGE
A "spillage" test must be made before the
installed unit is left with the customer. Follow
the procedure below:
1) Start all exhaust fans in the home and any
other gas appliances. Then close all doors
and windows.
2) Light the unit and set controls to maxi-
mum.
3) After five minutes, test that there is a "pull"
on the flue by placing a smoke match,
cigarette or similar device which gives off
smoke, on the edge of the draft hood. See
diagrams.
LOUVER

Note: The door latch may require adjust-
ment as the door gasket material
compresses after a few fires and
after glass replacement. Turn the
latch catch inward or outward to
loosen or tighten.
The smoke should be drawn into the draft
hood. If the smoke is not drawn into the draft
hood, turn the unit off and check for the cause
of lack of draft.
