1. Pick a location on a wall with a clear space of 36" (91.4cm)
high by 43" (109cm) wide in the room. In selecting a location
for installation, it is necessary to provide adequate accessibility
clearances for servicing and proper installation. Be sure to locate
the unit close enough to a 115 VAC wall receptacle to properly
power appliance.
2. Unit is supported by a wall bracket secured to the wall.
3. When facing the front of the furnace the minimum clearances
from casing to combustible construction are 10" (254mm) on
top, 3" (76mm) on each side, recommend 18" (457mm) on right
side for servicing and 0" (0mm) from the floor and 0" (0mm)
to rear wall.
4. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12" (305mm).
5. The minimum wall depth is 2" (51mm) and the maximum is
10"(254mm) [or 32"(813mm) using the extended vent terminal
kit accessory]. The use of vent tubes not supplied by the
manufacturer may result in unsatisfactory performance.
The vent terminal of a direct vent appliance, with an input of
50,000 BTU (14.6KW) per hour or more shall be located at least
12" (305mm) from any opening through which flue gases could
enter a building.
The bottom of the exhaust vent terminal and the air intake shall
be located at least 12" (305mm) above grade and must be vented
outside.
WARNING: The nearest point of the vent cap should be
a minimum horizontal distant of six (6) feet (1.83m) from
any pressure regulator. In case of regulator malfunction,
the six (6) feet (1.83m) distance will reduce the chance of
gas entering the vent cap.
Installation on Rugs and Tile
If this appliance is to be installed directly on carpeting, tile, or other
combustible material, other than wood flooring, the appliance shall
be installed on a metal or wood panel extending the full width and
depth of the appliance.
The base referred to above does not mean the fire-proof base as
used on wood stoves. The protection is primarily for rugs that may
be extremely thick and light-color tile that can discolo
r.
Locating Wall Opening (Figures 2, 3 and 4)
This furnace must be installed on an outside wall. Locate wall
studs so that wall vent opening will be located between wall studs.
The wall studs can be used for attachment of wall mounting bracket.
The wall opening required for venting is a 3 1/4" (83mm) diameter
opening.
Refer to Figures 2 and 3 for positioning the furnace on wall and
for locating gas line connection and vent opening. Furnace can
sit on the floor and should be secured to the wall through the wall
bracket secured to the rear top shroud.
