AUTOMATIC HUMIDIFIER OPERATION
Most gas heaters dry out the air in the room. The Mantis has in-
geniously solved this problem with an Automatic Humidifier.
Gas contains moisture which is normally expelled out the flue or
chimney after combustion. But the Mantis is so efficient by taking
92% of the heat out of the burnt gases that the moisture drops out
and condenses in the back of the heater. This water is collected
in a tank which is then pumped up to a stainless steel condensate
tray, where it evaporates in the stream of hot air which is blowing
into your home. Air humidity is automatically restored!
1. The amount of condensate build up in the water sump is dependent on outside temperature, length and height of the flue pipe. The
automatic humidifier can operate from approximately 10 minute to 6 hour intervals, depending on ambient temperature, style and
type of flue. Long single vertical flues can cause the humidifier to come on more often depending on heater settings.
2. When the automatic humidifier is engaged and is transferring the condensate into the holding tank, a hissing sound may be notice-
able. This occurs when the condensate enters the holding tank and is quite normal. The duration of the sound may vary from 3 to 30
seconds until the holding tank has been filled with the condensate.
3. When the automatic humidifier pump comes on to pump condensate into the stainless steal tray (located on the top of the heater),
the L.E.D. light (Page 36, Figure 43B) on the front panel will light up and flash while the condensate pump is operating, and then
extinguish after the pump has stopped operating. This means water has been pumped into the tank, and the automatic humidifier
operation will begin.
