Humidifier Operation
The Mantis Power-Vent High-Efficiency Fireplace has an auto-
matic humidifier designed into the heater. As the heater operates,
condensate is created and collected inside the heater. The con-
densate is then transferred to a pan where it evaporates into the
air stream. The humidifier does not operate with every cycle.
While the condensate is being transferred to the pan, it is normal
to hear a slight hissing sound. The Humidifier light will be illumi-
nated while the condensate is being transferred.
