8 Regency ® 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 sup-
ply. 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 indicates 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 acceptable. 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 recommend 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 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
hood is in the same atmospheric pressure zone
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.
