ADDITIONAL INFORMATION

If the inlet air damper does not open to provide dilution air, the PVC vent will sag due to excessive

temperature.

Propane units do not have a bypass in the gas solenoid valve. This may result in occasional cycling stand by between calls for heat. If you experience more than two stand by cycles per hour, consider replacing the main gas control valve.

If hard wiring is required by local codes, use the knockout provided on the blower control box.
