the air intake connection and drill a 1/8” tap hole into the PVC which lines up with the 7/32” clearance hole and secure
them together with a #10 x 1” sheet metal screw. Seal the joint between the intake pipe and the adaptor with RTV.
b. All intake piping may be PVC. There is a 0” minimum clearance between the air intake piping and all types of
construction.
c. To the extent possible, pitch horizontal air intake piping towards the outside.
4. Installation of Horizontal Fitting Terminals (Terminal Option A):
a. See Figure 7.42 for proper orientation of twin pipe horizontal terminals. Outer edge of exhaust coupling must be 10” or
less from the wall surface. (Figure 7.9)
b. Remove the gasket from the end of the integral exhaust coupling and insert Selkirk #2PF-HVST or #3PFHVST in its
place.
c. Add PVC intake per instructions from Part VII-F.
5. Installation of Vertical Fitting Terminals (Terminal Option H):
a. See Figure 7.43 for the proper orientation of twin pipe vertical terminals.
b. Remove the gasket from the end of the integral exhaust coupling and insert Selkirk #2PF-HVST or #3PFHVST in its
place.
c. A 180° bend (or two 90° elbows) are installed on the top of the air intake pipe. If two 90° elbows are used, the rodent
screen provided can be installed between them (Figure 7.43). If a 180° bend is used, install the rodent screen in the open
