Over Temperature Limit Switch
The Mantis Power-Vent High-Efficiency Fireplace is
protected against overheating with a high temperature
switch, which protects the heat exchanger, plastic sump
and inducer.
If the over temperature limit activates, the gas supply will
shut off and both the inducer and circulating air blower will
run. Once the heater cools down, the limit will reset and the
heater will operate normally.
Circulating Air Blower
The circulating air blower should be checked and cleaned
annually by a qualified service person to ensure that your
appliance is operating efficiently. Any dirt or lint can affect
the operation of the blower.
RECOMMENDED MAINTENANCE
