Field controls cv-5 (CV5) combovent 46521802 power vent
NOTE: Control Kits are required for operation of the ComboVent see below for list of controls.
Please email us for pricing and availability
Designed for operation with natural gas, LP gas and #2 fuel oil appliances.
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 closes the circuit to the burner and allows the burner to fire.
2. For millivolt controlled water heaters using the CK-20 Series Control Kit, the gas valve pressure switch 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. 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.
