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 hood
is in the same atmospheric pressure zone as the
combustion air inlet to the burner. This heater must
be properly connected to a venting 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

The U38E-11 is approved in Canada for altitude 0
ft. to 4500 ft. (CAN/CGA-2.17-2017). For Natural
Gas installations above 4500 ft. follow current CAN/
CGA-B149.1-15.
In U.S.A., for installations above 2000 ft. refer to
current ANSI Z223.1 Sc8-8.1.2a appendix F, for
resizing orifice.

Venting

This heater is a vented appliance and must be
connected to a chimney/flue in accordance with
the installation codes.
Note: The rear pedestal cover plate is only
required when outside air is being used.
If using room air for combustion, remove
this plate from the back of the pedestal.
For your safety this heater is equipped with a vent
safety switch designed to sense incorrect venting and
react by shutting down the gas supply. 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 never
be bypassed or disconnected as a 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 accept-
able. For cosmetic or aesthetic purposes 6" outer
vent can be used as long as an approved inner vent
is installed. Fasten but do not penetrate the inner
sleeve of the B-Vent when tightening the screw.
Follow all venting manufacturer's requirements and
local building codes. In cold climates, we recom-
mend 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 enclosed
screw as shown in the diagram.
