Includes: Pressure switch and post purge controls.
Used for sidewall venting of a single 24 VAC controlled furnace, boiler, or water heater which burns natural or LP gas. The PVG may also be used to vent a single 24 VAC controlled gas fired furnace or boiler and a 30 millivolt residential gas fired water heater.
How the PVG Works- 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.
