1. Vent and air piping must terminate out the sidewall or through
the roof of the building, using only one of the methods described
in this manual.
2. Sidewall options (see Figure12,page18, le side):
a. TOP: Weil-McLain termination cap (kit included with
boiler) — see page67 for instructions.
b. MIDDLE: Concentric PVC pipe (requires special kit,
page129).
c. BOTTOM: Separate air pipe and vent pipe.
3. Vertical options (Figure12,page18, right side):
a. TOP: Concentric PVC pipe (requires special kit, page129).
b. BOTTOM: Separate air pipe and vent pipe.

Step 3 Determine proper location for wall or roof penetration for
each termination.
Step 4 Install termination assembly as described in this manual.
Step 5 Install air and vent piping from boiler to termination.
Step 6 Install pipe supports and brackets as required.
