The vent terminal of a direct vent appliance, with an input of 10,000
Btu per hour (3 kW) or less shall be located at least 6" (150mm)
from any air opening into a building, and such an appliance with an
input over 10,000 Btu per hour (3 kW) but not over 50,000 Btu per
hour (14.7 kW) shall be installed with a 9" (229mm) vent terminal
clearance and 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) feet (1.8m) from any
pressure regulator. In case of regulator malfunction, the six
(6) feet (1.8m) distance will reduce the chance of gas entering
the vent cap.
1. In selecting a location for installation, it is necessary to provide
adequate accessibility clearances for servicing and proper
installation.
2. Although certified for 0 clearance to the floor , the unit is held in
place by a wall bracket. Enough clearance [2" (51mm) suggested]
to allow changing or adding floor covering is recommended.
Other clearances to combustible construction:
Sides 1" (25mm) and 12" (305mm) from the top.
3. Note the position of the vent relative to the center of the unit.
The DV-210 has the vent in the center. The DV-215 vent is 2"
(51mm) off center to the right.
4. The minimum distance from the center of the outside vent to
the nearest outside corner or obstruction is 16" (406mm).
5. The DV-210/DV-215 minimum wall depth is 4 1/2" (114mm)
and maximum wall depth is 13" (330mm). The use of tubes
not supplied by the manufacturer result in unsatisfactory
performance.
The furnace is to be located on an outside wall. Locate wall studs
so that wall opening will be located between wall studs. One wall
stud can be used for attachment of inside wall plate. The wall
opening required as shown in Figure 3 is a minimum diameter
of 6 1/4 (159mm) inches. The inside wall plate and the outside
wall plate are large enough to permit a wall opening diameter of
8 inches (203mm).
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.
