INSTALLATION

•
Optional bird screen may be placed in a termination fitting. Leave unglued,
and hold in place with a short nipple to allow easy access for cleaning.
•
For roof top venting of multiple unit sets, group all intake terminals together
for a common penetration through a custom cap. Alternatively, place in
the closest proximity achievable using commonly available pipe flashing.
Similarly, group the exhaust pipes and place the 2 separate groups of pipes
at least 3' apart (the closest intake and exhaust pipes must be 36" - or more -
apart). Use the same 12" (minimum) vertical separation for 2 pipe option.
•
DO NOT exhaust vent into a common venting system.
