Floor Protection Requirements
•When the stove is installed directly on carpeting, vinyl or other combustible material other than
wood flooring, the stove must be installed on a metal or wood protection panel extending the full
width and depth of the pedestal (Minimum 24-1/2" (622 mm) wide by 20" (508 mm) deep).
Stove Placement Requirements
•Heater must be installed on a level surface capable of supporting the heater and vent
•Due to the high temperature of the heater, it should be located out of traffic and away from furniture
and draperies. Heater must be placed so no combustibles are within, or can swing within 36" (910
mm) of the front of the heater (e.g. drapes, doors)
?When placed in a location where the floor to ceiling height is under 7 feet (2130 mm), the
installation is considered an alcove and must meet the following requirements:
•The alcove floor to ceiling height must be at least 58" (1470 mm) tall
•The alcove must not be more than 48" (1220 mm) deep before the ceiling returns to 7' (2130 mm)
• The alcove must be at least 44-1/2" (1130 mm) wide
•The stove must not be placed so the vents below or above the door, along the sides of stove, or along
the back of the heater can become blocked.

•With the heater off, the inlet pressure must meet the requirements listed in the table below
?If the pressure is not sufficient, make sure the piping used is large enough and the total gas load for
the residence does not exceed the amount supplied.
?The supply regulator (the regulator that attaches directly to the residence inlet or to the propane tank)
should supply gas at the suggested input pressure listed below. Contact the local gas supplier if the
regulator is at an improper pressure.
Standard Input Pressure
Natural Gas 7" W.C. (1.74 kPA)
Propane 11" W.C. (2.73 kPA)

PAGE 12 STOVE INSTALLATION (CONT.)- For Qualified Installers Only!
Vent Requirements
!Always maintain the required 1" clearance (air space) to combustible materials to prevent a fire
hazard. Do not fill air spaces with insulation.
!The gas appliance and vent system must be vented directly to the outside of the building, and never
be attached to a chimney serving a separate solid fuel or gas-burning appliance. Each direct vent gas
appliance must use it's own separate vent system.
!If the stove is installed at an
altitude over 3,000 feet
(1,000 M) the flame quality
will need to be carefully
evaluated. See Addendum
#1, "Altitude
Considerations", on page 38.
•When the vent passes through
a wall, a wall thimble is
required. When the vent
passes through a ceiling, a
support box or firestop is
required. When the vent
passes through the roof, a
roof flashing and storm collar
are required. Follow the
instructions provided with the
vent (from Duravent®) for
installing these items.
Use a firestop spacer whenever
passing through a ceiling

estrictor Position
•A vent restrictor is built
into the appliance to
adjust the flow rate of
exhaust gases. This
ensures proper flames
for the wide variety of
vent configurations. The
restrictor consists of a
butterfly valve below the
starter section of pipe
and an adjustment plate
with index holes used to
hold the valve in a fixed
position. Depending
upon the vent
configuration, you may
be required to adjust the
restrictor position. The
charts for approved vent
configurations describe
which position the vent
restrictor must be in.
