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 different sizes consider reducers and specific size pipe when determining equivalent length of vent pipe.

SWH-1-3 - 3 inch SWH-1-4 - 4 inch SWH-1-5 - 5 inch SWH-1-6 - 6 inch SWH-1-8 - 8 inch

SYSTEM OPERATION

Figure 1

Figure 2

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 fire.

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 fires.

3.After the heating requirement has been satisfied, 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 flue gases.

POWER VENTER SIZING

In order to choose the correct size power venter for a particular installation, the total input firing rate and total equivalent length of vent pipe to be used must be known. Refer to Table 2 to determine the maximum allowable equivalent feet of pipe for each model used with the pipe diameters shown. When venting multiple appliances, add the input of each appliance to determine the total input. Always choose a power venter that is capable of handling more than the system requires. The choke plate can be adjusted to compensate for the difference.
