SIDEWALL VENT HOODS (Model SWH-1)
Sidewall vent hoods are available in the following sizes. The vent hood should be chosen that matches the
outlet size of the Power Venter. (See Figure 2) NOTE: When using diff erent sizes, consider reducers and
specifi c size pipe when determining equivalent length of vent pipe.

SYSTEM OPERATION

1. The thermostat (wall thermostat, or aquastat) calls for heat and energizes a relay which activates the
power venter. After the venter motor has come up to speed, the pressure switch closes. This completes the
circuit to the burner and allows the burner to fi re.
2. For millivolt controlled water heaters, the gas pressure switch on the gas valve activates the power venter
at the same time as the burner fi res.
3. After the heating requirement has been satisfi ed, the thermostat circuit will open and de-activate the
burner and power venter circuit.
4. The post purge timer continues to run the power venter for a period of time after the burner has shut off to
purge remaining fl ue gases.
