Venting Straight Up Through Roof; Roof Flashing - Kingsman “Zero Clearance” ZDV1001 Installation Instructions Manual

Venting Straight Up Through Roof

1. An Attic Insulation Shield must be installed where the vent passes
from a lower living space into an attic space where the chimney is
not enclosed. It is designed to keep insulation materials away from
the chimney. See Fig. 1.
2. When installing the Attic Insulation Shield where the chimney pass-
es from a living space to an attic space, install the shield from
below and nail in place using 1" spiral nails.
3. A fire stop must be installed on the bottom side of the joists when
passing through a ceiling or floor. If an attic insulation shield is to
be used, a fire stop is not required.

Using Flex Bends
4. Avoid cutting joists by offsetting the flex pipe. See Fig. 2.
5. Maximum horizontal offset when using 45˚ bends is 6 feet.
6. When using 45˚ bends an bend support is required directly above
the highest bend.
7. Never install a bend in a joist area. Vent sections must pass vertical-
ly through framed joist areas.
8. Maximum vertical height of system should not exceed 20 feet.
9. Use roof support and 7" ridge pipe at roof level. Flex not permitted
with in roof support.
10. When penetrating the roof a ridge 7" pipe must be used. Attach the
7" flex to the 7" ridge with high temperature sealant, clamp security
with adjustable clamp, and use two screws/washers either above or
below camp assuring the flex and ridge pipe are secured. 4" flex
pipe must be secured the same way with 2 screws and washers
either above or below the clamp but must penetrate the 4" flex and
4" section of termination. Attach 7" ridge to 7" termination with
sealant and screw with 3 sheet metal screws. (See Fig. 3).

Roof Flashing

Ensure that you have the proper roof flashing by checking your roof
pitch using a level and two rulers, or by using a roof pitch card. See fig-
ure below.
Slide a Roof Flashing suitable to your roof slope over the vent. Place
the edge of the flashing plate that will be on the higher part of the roof
slope under the shingles. Both the sides and the lower edge lay on top
of the shingles.
NOTE: At the top edge of the flashing plate, lift the shingles and
nail the plate to the roof deck, then cement the shingles to the plate
with a suitable waterproof mastic.
FIG. 2
Ensure that the chimney is plumb. Square up the flashing plate and nail
in place to the roof deck. Use 12 nails with neoprene washers or cover
the heads with a suitable waterproof mastic.
Wrap the storm collar around the vent above the flashing. Secure the
ends together loosely with nut and bolt supplied. Slide the collar down
the vent until it comes in contact with the flashing. Tighten the bolt and
seal the Storm Collar to the vent with a suitable waterproof non-com-
bustible mastic.
The flashing and storm collar should be painted to match the roof shin-
gles. This will extend its life and improve the appearance. Clean, prime
and paint the suitable painting products.
Continue adding lengths of vent until the proper height is achieved (See
diagram above). Slide raincap into vent.
