When using a moisture restoration system in cold regions, a source of hot air separate from the Humidaire Unit is helpful for pre-warming the Steamroller, Moisture Condenser, or lint slide jacket. The HG-1-1401A heater is built for this purpose. It includes PLC combustion controls with diagnostics. It has built-in temperature controls with a 2-HP fan and motor combination capable of delivering up to 3,000 CFM of tightly controlled, reliable hot air.

The STATUS light will remain on throughout this process. After approximately 20 seconds, the burner will attempt ignition. If ignition fails, the heater controls will automatically make two more attempts following appropriate air purge delays.
