Saftey Features

• First is the OXYGEN DEPLETION SENSING system (Indoor Model Only). Emissions from the sampling burner are constantly analyzed for carbon monoxide gas. If necessary, the fan speed is adjusted by the on board CPU. If the fan speed adjustments do not resolve the combustion problem, the burner will be turned off and a potentially dangerous situation avoided. An error message will be displayed.


• Second is the FILM TYPE OVERHEAT SENSING. This senses high temperature at all positions surrounding the combustion chamber. Other manufactures only sense at one point on the combustion chamber.

Two remote controls (one main control and one bath remote control) can be installed together. One Main control comes with each unit.

Warranty

• 10 Year warranty on heat exchanger.
• 3 Year warranty on parts.
