INSTALLATION INSTRUCTIONS (continued)
3. Attach 6" (152mm) diameter air inlet tube onto the collar of air
drop assembly. Attach caulked, outside mounting plate into the
6" (152mm) diameter air inlet tube. Position the outside mounting
plate so that 6" (152mm) diameter air inlet tube has a slight
downward slope to the outside. The downward slope is
necessary to prevent the entry of rainwater. Attach outside
mounting plate to exterior wall with (4) #10 x 1 1/2" (38mm)
screws provided.
4. Apply furnace cement or RTV silicone sealant to 4" (102mm)
diameter flue outlet collar on combustion chamber and to 4"
(102mm) diameter collar on vent cap. Attach 4" (102mm)
diameter flue outlet tube onto flue outlet collar on combustion
chamber. Attach vent cap into the 4" diameter flue outlet tube.
Attach vent cap to outside mounting plate with (3) #10 x 1/2"
(13mm) screws provided.
5. Reassembly and resealing vent-air intake system is completed.
Installing a Vent Near a Window Ledge,
Other Type of Projection or on Vinyl Siding
Direct vent furnaces are designed to be installed on a uniform
outside wall. When the wind comes from any angle (up, down or
from either side), it must hit the vent cap equally over both the
air inlet and the flue outlet portions of the vent. Any wall projection,
such as a door or window casing, which disturbs the wind on one
side of the air inlet section will result in back pressure on the flue
section smothering the flame and eventual pilot outage.
When the vent cap is to be installed on vinyl siding or it appears
that a projection within 6" (152mm) of any side of the air inlet
section could shield the air inlet section, the entire vent should be
supported away from the wall at least the distance of the projection.
2" x 4" (51mm x 102mm) framing whose outside dimensions
match the overall dimensions of the mounting plate is
recommended. The 2" x 4" (51mm x 102mm) framing protects
vinyl siding from possible warpage or discoloration. All joints can
then be sealed and painted. The wall depth plus the additional
depth of the 2" x 4" (51mm x 102mm) framing should not exceed
a total depth of 10" (254mm) for DVC-35. (See Figure 9) If it does
you will need to use the DV-1190 Extended Flue Kit.

Vinyl siding vent kit, DV-822, is available from Empire Comfort
Systems, Inc. The depth is 3" (76mm), which enables the vent cap
to be extended away from vinyl siding or projections. The wall
depth plus the additional 3" (76mm) depth of the vinyl siding vent
cap extension should not exceed a total depth of 10" (254mm) for
DVC-35. (See Figure 10)
Warning: When vinyl siding vent kit, DV-822 or 2" x 4"
(51mm x 102mm) framing is added to an existing
installation (furnace is installed) do not attempt to add
sections of pipe to the flue outlet tube or air inlet tube. An
air tight seal is required for both tubes. Refer to Parts List,
page 19 to order tubes.
