Wall Thimble
(Not Supplied)
1. Locate the power vent termination following the clearance to combustible table, venting
confi guration diagram (Fig. #51), and terminal location diagram (Fig. #28).
2. Cut and frame an 11” x 11” opening. The centre of the square hole should line up with
the centre line of the horizontal pipe.
3. Install the Simpson Duravent (or equivalent) Wall thimble, part number 1247 (not
supplied with kit) in the opening to retain any insulation in the wall and maintain proper
clearances. If the wall being penetrated is constructed of noncombustible material only
(i.e.. Masonry block or concrete) the wall thimble is not required and a hole with zero
clearance is acceptable. (8” hole)
4. Drill an appropriate sized hole in the corner of the wall thimble that is in line with the
wiring hole in the back of the power vent and bring the 14-2 electrical wire (not supplied)
up through the holes in both the wall thimble and the back of the power vent.
5. Remove the Junction Box cover and join the 14-2 wire lead to the blower wires using
the appropriate connectors and attach the ground wire. Reinstall the junction box cover.
6. Attach the terminal to the outside wall. Ensure that the terminal is the right way up and
that only the outer fl anges that are used to secure the terminal to the building are covered
by the exterior wall or siding. (Fig.#52)
Note: No other part of the terminal can be
recessed into the exterior wall or siding.
7. Run the required Simpson Duravent GS / Secure Vent / Selkirk Direct-temp/ ICC Excel
Direct vent pipe from the unit to the terminal assembly. Assemble as per the vent pipe
manufacturer’s instructions including all shields and fi restops.
