information can be found at
www.novaex.com, refer to page

CAUTION: Follow the vent
manufacturers installation
instructions as design might vary
om manufacturer to
manufacturer.
Only the 2.5” vent kit provided with the i12 or approved Z-Flex
Stainless Steel venting should be used for installation.
The wall thimble requires mechanical support from the wall suf-
fucuent to support any incidental loads on the system. If the wall is
not sucient enough to support the wall thimble, then appropri-
ate additional framing and/or blocking is required.
Installation Procedure:
Prepare an opening for the wall thimble in the wall. The opening
must be 6-1/2 inches in diameter for a 3” vent system. The opening
should be round.
The opening must be able to accommodate the 2” vent system and
wall thimble provided. Consult manual or building codes for distance
from amable materials.
The wall thimble is designed to adapt to any wall thickness from
3-1/2” to 6” thick. If the wall is thicker than 6” the wall thimble may
be extended using a piece of 6” diameter snaplock or welded seam
galvanized pipe up to 6” long.
Select the larger diameter half of the wall thimble for the outside of
the wall.
• Apply a continuous bead of high quality silicone or silicone/la-
tex caulk on the inside of the outer ange. This will be the only
weather seal to keep moisture outside the building. Ensure a
sucient seal is made.
• Position this portion of the wall thimble into the prepared hole
from the outside. Secure the assembly into the prepared open-
ing using fasteners as indicated by sheathing or structural mem-
bers, sealing the screw heads with more caulking.
Use 4 hollow wall anchors, at least 1/8” in diameter and of appropri-
ate length for the thickness of the sheathing, if sheathing is particle
board or other composite material. Use 4 #10x1-1/4” wood screws
for plywood, solid wood sheathing or members. Use suitable mason-
ry anchors when passing through solid masonry walls. Reinstall the
decorative sheathing around the wall thimble. This assembly may be
painted to match the exterior decor.
• Slide the interior portion of the thimble into the inside hole. Be
certain the interior and exterior thimble halves overlap at least
1”. If insucient overlap exists, extend the interior portion with
single wall galvanized pipe.
• Secure the vent section that protrudes through the wall thimble
to the 90 degree elvbow attached to the water heater.
• The exhaust pipe should be sloped downward at an approximate
3 degree grade in order to avoid rain (or condensation entering
the heater) through the exhaust pipe.
