B. SIDEWALL VENT HOODS (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. Note: Different sizes may be used as long
as the reducers and specific size pipe are considered when determining equivalent length of
vent pipe.

C. CONTROL KITS:

The following are the most commonly used Control Kits.
CK-20F: For operation with 30 millivolt or 750 millivolt gas-fired water heaters, gas-fired

space heaters and gas-fired pool or spa heaters with an internally mounted
thermostat. Includes a non-adjustable post purge timer. Use the CK-22 for an
adjustable post purge timer.

CK-21: For operation with gas-fired instantaneous water heaters with a pressure tap port

in the burner manifold.

CK-41: For operation with gas-fired furnaces, boilers, unit heaters and water heaters

operating with a 24 VAC gas valve.

CK-43: For operation with draft induced gas-fired furnaces, boilers, unit heaters and water

heaters operating with a 24 VAC gas valve. Includes an adjustable post purge
relay/timer, and a draft control for draft induced appliances. Use the CK-43F for a
non-adjustable post purge relay/timer. Use the CK-44F for draft hooded
appliances.

CK-61: For operation with all 120 VAC oil-fired systems. Has electronic post purge. Use

the CK-62 for a thermally activated post purge.

CK-81: For operation with 750 millivolt operated boilers, furnaces, water heaters, pool or

spa heaters and gas-fired fireplaces when operating with a remote mounted 24
VAC thermostat. For operation with a 120 VAC thermostat or wall switch, use the
CK-80.

CK-91: For operation with a draft induced gas-fired furnace or boiler and a 30 millivolt

operated water heater. Includes an adjustable post purge relay/timer and a draft
control. Use the CK-92 for draft hooded appliances. Use the CK-91F or 92F for a
non-adjustable post purge relay/timer.

II. SYSTEM OPERATION

A. 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.

B. 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.

C. After the heating requirement has been satisfied, the thermostat circuit will open and de-

activate the burner and power venter circuit.

D. For venting systems equipped with a post purge device, the power venter operates for a

period of time after the burner has shut off to purge remaining flue gases.

III. 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 the following
sizing chart 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.

A. PROCEDURE FOR CALCULATING TOTAL EQUIVALENT PIPE LENGTH IN FEET:

1) Calculate the total equivalent feet for each type of fitting used in the venting system from
the chart below.

2) Calculate the total amount of feet for the straight lengths of vent pipe.

3) Add the equivalent feet for the fittings with the total amount of feet of straight lengths.
