easy after cutting the wall opening secure the vent terminal box
in place using the (4) 10 x 1" hex-head screws provided. Locate
the box so that the middle exhaust tube is directed toward the
furnace exhaust outlet opening. See Figure 8. Attach the black 2"
using a hose clamp. Secure the other end to the lower inlet air box
connector using the hose clamp. Do not kink hose. Attach the long
straight end of the 2" orange silicone exhaust elbow to the middle
vent terminal tube and rotate the elbow toward the furnace exhaust
outlet. Secure the hose to the vent box using a hose clamp. Carefully
push the furnace back closer to the wall and secure the exhaust
elbow to the 2" exhaust tube exiting the unit. Secure the elbow in
place using the last remaining hose clamp. The furnace can now
be secured to the wall.
The furnace can be vented with up to a maximum length of 15'
(4.6m) including termination vent and using 2 - 90° elbows. Also,
the furnace can be vented with up to a maximum length of 10' (3m)
including termination vent and using 3 - 90° elbows. For longer vent
lengths order the vent kit, Part Number DVE-1 and DVE-2. See
Figures 11 and 12 illustrating extended vent run and venting options.
NOTE: If the extended vent kit is used and the exhaust vent pipe
is run through a cold space, such as an attic or a garage, the pipe
condensation. Also, slope 1/4" (6mm) per foot (305mm) the vent
vent pipe runs of 5 feet (1.5m) or more in length may accumulate
condensation in the exhaust pipe and must, therefore, be sloped
downward to drain any condensate out of the end vent terminal.
Use straps or other suitable supports spaced every 5 feet (1.5m)
to adequately hold pipe. Be sure to avoid any low spots or sags in
pipe run. Be sure all connections are tight using the hose clamps
as shown in Figure 9, "Vent Coupling Connections."
For wall depths thicker than 10" (254mm) order the extended vent
terminal kit which will cover walls to 32" (813mm) thickness. The vent
pipes must be cut to length to assemble for desired wall thickness.
For extended venting, it is also acceptable to use 2" (51mm) diameter
PVC or ABS pipe for the combustion air intake supply piping only to
and ASTM Standards D1785 for SCH. 40 PVC, D2665 for PVC-
DWV, D2241 for SDR-21 and SDR-26 PVC, D2661 for ABS-DWV
and F628 for SCH. 40 ABS. Pipe cement and primer must be used
and conform to ASTM Standard D2564 for PVC or D2235 for ABS.
This PVC or ABS pipe must not be used for the exhaust vent
pipe run.
NOTE: Type SDR pipe is not approved for use in Canada.
For new construction installation, the intake and exhaust vent can be
wall. This can be done but not the preferred method of installation
due to the inability to perform periodic inspection of the vent system.
In doing this, it is important to securely seal the vent system and
toward the vent terminal outside to drain out any condensate. It is
also necessary to adequately support both the exhaust and intake
and to center the exhaust pipe in the wall.
Be sure to consult local codes prior to installation to verify allowable
procedures.
Installation of Shroud
To complete inside installation, secure furnace to the wall bracket
by attaching the two wall mounting brackets to the wall bracket by
using (2) 10 x 1/2" (13mm) hex-head screws provided. See Figures
4 and 6. To attach the right shroud and left shroud to the casing
the casing side. When positioned correctly, the (6) louvers on the
shroud will be facing up and the knock-out on the shroud will be
facing down. Attach the right shroud and left shroud to the casing
back with (3) 10x1/2" hex-head screws supplied in hardware package,
for each shroud. Attach top shroud to right shroud and left shroud
with (4) Phillips-head screws, supplied in hardware package. Insert
be able to be installed onto the side shrouds. The top shroud will
appear to be 2 inches, too narrow.
Vent Terminal (Figure 10)
Place the 6 3/8" x 6 3/8" (162mm x 162mm) black foam, wall plate
gasket within the mounting plate. The 4 3/4" (121mm) diameter hole
in the black foam gasket will allow for installation of the concentric
vent tube assembly. Slide the outside mounting plate into place on
the concentric vent tube assembly. The outside mounting plate should
seal against the face of the building and be secured in place using
(4) 10 x 1" hex-head screws. Be sure to caulk and seal around the
pipe on the exterior using high temperature exterior grade, silicone
caulk rated at 204°C/400°F. Wipe some silicone sealant on the 2"
(51mm) exhaust pipe extension. The end cap can be pushed into
place on the exhaust outlet tube.
Attention: The opening on the bottom of the end cap must be
positioned toward the ground. The opening on the bottom cannot
be pivoted to the right or left, it must be centered toward the ground.
