Room size for which this heater is suitable will vary depending on outside temperature, house insulation,
window size, and other factors.
Flame Sensor
Heater will automatically stop all operations if ignition fails or if flame fails during combustion, in order to
prevent fuel overflow. Error code will be displayed on the Operation panel.
Fuel Strainer
Special strainer catches dirt and impurities present in the fuel before it is sent to the burner.
Overheat Protector
Automatically stops all operations if the heater's inside cabinet reaches abnormally high temperature due to
motor malfunction or abnormal combustion, in order to prevent fire.
Power Failure Recovery System
If power fails during heater operation, heater will automatically reignite and maintain the normal selected
temperature, when power resumes.
Fully Vented System
Flue pipe system uses outside air for combustion and vents all combustion products to the outdoors.
