Raypak 335 Water Heater User Manual


 
6
The Raypak Power Vent operates with a positive vent static pressure and with a vent gas
temperature that avoids excessive condensate production in the vent and as such it is listed
as a CATEGORY III appliance.
Exception: When a Power Vent is connected to a vertical vent of sufficient height to generate
a negative draft in the system. Consult sizing guide or factory.
The D-2 Power Vent assembly is suitable for through the wall venting, and for connection
to smaller size vent pipes and breeching other than the standard atmospheric heater.
The D-2 Power Vent assembly includes a wire harness which provides quick connections with
the respective controls in the heater control box. The harness is of sufficient length to fit the
appliance for which it is sized.
Reference the wiring diagram supplied with each appliance for actual connections.
