SWH
Accessories
1. Thermostat or aquastat calls for heat and starts the
Power Venter.
2. The Pressure Switch senses sufficient air flow and
allows burner(s) to start.
3. The Power Venter draws combustion air through the
system and forces gases outside through an external
Vent Hood.
4. Draft Hood or Barometric Draft Control between the
appliance(s) and the Power Venter maintains
consistent air flow.
5. After the thermostat is satisfied, the burner shuts
down and the Post Purge Control clears the venting
system of combustion gases.
6. The Power Venter shuts down.
The indoor mounted PVG and PVO Power
Venters provide an economical power venting
system for gas and oil appliances. All controls
are built into these units. A Vent Hood is required
to terminate the vent system.
