Note: The flange used for assembling the igniter is
easily breakable. The screws in
four positions should be slowly
fastened by turns. In case the
flange is broken, heated air is
contaminated with raw gas,
generating odors. If the broken
flange must be used, apply heat
resistive putty (which is a repair
putty for automobile muffler) to the
F-part for installing the igniter.

position, the heater consumes a
power of approximately 96W for ignition for approximately 3 minutes. As the
battery capacity decreases, the voltage decreases (lower than approximately
10V) at the same time as ignition is made, which causes heater operation to
stop. A heater operation similar to this failure may be caused by reduced
battery capacity while in operation. Check on the battery and recharge it if
necessary.
Note 2: In the event the motor speed is less than 2500rpm at High or 1200rpm at Low,
the heater will stop operation. At that time three lamps will flash in order turn.
