Pick a location on an outside wall with a clear space of 28" (711mm) high
by 49" (124cm) wide in the room.
Clearances
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.
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 1 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 1 for positioning the furnace on wall and for
locating gas line connection.
Figure 1 will position the furnace four inches (102mm) 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.

Locating Gas Supply
The gas line can enter the unit either through the floor or outside wall. The
gas line opening should be made at this time. Location of the opening will
be determined by the position of floor joists and the valve and union used
for servicing.

Installing Wall Mounting Bracket
Locate and cut wall opening. If there is insulation above the wall opening
(air inlet tube) a barrier should be installed above the wall opening (air
inlet tube) to prevent insulation from coming in contact with the air inlet
tube. The barrier must not penetrate into the 7 1/2" (191mm) diameter
wall opening. Place the flat surface of the wall mounting bracket toward
the wall. Insert half round flange of wall mounting bracket into and at the
top of the wall opening. The half round flange of the wall mounting
bracket must be in contact with the sheetrock or wood at the top of the wall
opening. Level the wall mounting bracket in the wall opening.
On solid wall, when using wall studs for attachment of wall mounting
bracket, fasten wall mounting bracket to wall studs with (2) #10 x 1 1/2"
(38mm) screws provided and fasten (2) additional #10 x 1 1/2" (38mm)
screws provided through the wall mounting bracket and into the solid
wall.
On sheet rock, when using wall studs for attachment of wall mounting
bracket, fasten wall mounting bracket to wall studs with (2) #10 x 1 1/2"
(38mm) screws provided and by using wall opening for access, fasten 2
additional #10 x 1 1/2" (38mm) screws and (2) Tinnerman nuts provided
through the wall mounting bracket and into the sheet rock.
Attaching Furnace To Wall Mounting Bracket
Hang furnace on wall mounting bracket by aligning (2) tabs on wall
mounting bracket with (2) slots located on inner casing top.
The inner casing bottom is to be fastened to the wall. On solid wall,
fasten inner casing bottom with (2) #10 x 1 1/2" (38mm) screws
provided. On sheet rock wall, fasten inner casing bottom with (2)
toggle bolts provided.
Cutting Vent Tubes
This is the most important part of the installation. With the furnace
installed on wall the 6" (152mm) diameter air inlet tube and the 4"
(102mm) diameter flue outlet tube are to be marked and cut using the
following procedure.
