Exhaust and intake opening
The temperature in furnace may not reach to the operating temperature when the unit is used
with its exhaust opening or air intake opening opened. In this case, close them as possible.

operation after a power failure. We recommend for you to turn off the switch of this unit if a
power failure occurs during operation.
