ADJUSTING THERMOSTAT ANTICIPATOR

If connecting the Power Venter system to a gas appliance with a thermostat anticipator, refer to the following to make adjustments. Disconnect one side of the thermostat circuit at the gas valve or burner control, and connect an ampere meter into the circuit. With the system running, take an amperage reading on the circuit. Check the nameplate or instructions for the thermostat to obtain the proper amperage level. Adjust amperage level by moving the anticipator lever. Reconnect the thermostat to the gas valve and start the system operating. Time the burn cycles and adjust as follows; To make the cycle time longer, increase the amount on the anticipator (Example: .45 to .5 Amps); to decrease cycle time, reduce the amount on the anticipator. (Example: .45 to .3 Amps) (See Figure 8)
