U38-1 ULTIMATE Freestanding Gas Stove
INSTALLATION
VENTING
This heater is a vented appliance and must be
connected to a chimney/fl ue 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 fl ow has
reversed. If this switch shuts the unit down, it in-
dicates a drafting problem that must be identifi ed
and rectifi ed 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 fl ue height of 12 ft. is used.
Flue Mounting Bracket
Attach the fl ue mounting bracket with the enclosed
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 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 U38-1 (with 40,000 BTU rating) is approved
in Canada for altitude 2000 ft. to 4500 ft. (CAN/
CGA-2.17-M91) with the orifi ce kit (Part # 591-975).
For Natural Gas installations above 4500 ft. follow
current CAN/CGA-B149.1.
In U.S.A., for installations above 2000 ft. refer to
current ANSI Z223.1 Sc8-8.1.2a appendix F, for
resizing orifi ce.
