Which power venter is better, the SWG series or the PV series?
The SWG series power venter is the safest of the power venters to use since it will keep the venting system under a negative pressure. With the system under a negative pressure, if a crack occurs in the flue pipe it will draw air in through the crack instead of leaking the flue gases out, which is what happens with a positive pressure system. Both power venters work just as well in venting flue gases, but the SWG is the safest.
