NOTES:
1. If the appliance flue outlet is greater than
4'', install a tapered reducer after the
draft hood, draft diverter or barometric
draft control, reducing vent pipe diame-
ter to 4''. All vent pipe from the appliance
to the Power Venter may be 4''.
2.Table is based on straight vent pipe. 90
degree elbows are equivalent to 6 feet of
straight vent pipe.
3.Determine maximum pipe length from
type of equipment being vented and
GPAK Model. Column A pipe runs
over 30 linear feet should use Type
“B” vent. Column B & C pipe runs
over 15 linear feet should use Type
“B” vent.
