1. In selecting a location for installation, it is necessary to provide
adequate accessibility clearances for servicing and proper
installation.
2. Unit is supported by a wall bracket secured to the wall.
3. The minimum clearances from casing to combustible construction
is 48" (121cm) on top, 6" (152mm) on each side and 4" (102mm)
from the floor or from the top surface of carpeting, tile or other
floor covering 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 24" (610mm).
5. The DV-25 and DV-35 minimum wall depth is 4 1/2" (114mm)
(and the maximum is 13" (330mm). The use of tubes not
supplied by the manufacturer results in unsatisfactory
performance.
The vent terminal of a direct vent appliance, with an input of
50,000 (14.6 KW) BTU per hour or less shall be located at least 9"
(229mm) from any opening through which flue gases could enter a
building. The bottom of the vent terminal and the air intake shall
be located at least 12" (305mm) above grade.
WARNING: The nearest point of the vent cap should be
a minimum horizontal distant of six (6) (1.83m) feet from
any pressure regulator. In case of regulator malfunction,
the six (6) (1.83m) feet distance will reduce the chance of
gas entering the vent cap.
Location of Furnace
Pick a location on an outside wall with a clear space of 28" (711mm)
high by 49" (124cm) wide in the room.
Locating Wall Opening
The furnace is to be located on an outside wall. Locate wall studs
so that wall opening will be located between wall studs. The wall
studs can be used for attachment of wall mounting bracket. The
wall opening required as shown in Figure 3 is a diameter of 7 1/2
inches (191mm).
A template is provided in furnace carton for positioning furnace
on the wall. Also, refer to Figure 3 for positioning the furnace on
wall and for locating gas line connection.
Figure 4 will position the furnace four inches off the floor. If it is
desired to position the furnace higher on the wall, add the difference
to the "A," "B" and "C" dimensions. Note: The vent opening is
not in the center of the furnace.
