Mt. Vernon Pellet Stove (AE)

17. Power Supply

The power supply is located at the rear of the appliance.  It 

converts 10 volt AC current to 15 volt DC current to power 

the appliance.

18.  Overheat Sensor (Snap Disc)

The  overheat  sensor  is  mounted  on  the  back  of  the  drop 

tube in the center of the appliance and has a reset button.  

To access it remove the right side panel.  If the fire tries to 

burn back into the feed system or push exhaust up the feed 

tube, this sensor will shut the appliance down, however the 

wall control will still display messages.  This sensor must be 

manually re-set.  Disconnect power before resetting.

19.  Thermocouple - Firepot

This  thermocouple  is  located  on  top  of  the  firepot  inside 

the  thermocouple  cover  (ceramic  protection  tube).  The 

thermocouple  sends  a  millivolt  signal  to  the  control  board 

telling the control board there is a fire in the firepot.

20.  Thermocouple - Drop Tube

This  thermocouple  is  located  on  the  bottom  of  the  drop 

tube on the right side and attached with a wing nut.  It turns 

the  convection  blower  on  and  off,  varies  the  speed  of  the 

convection  blower  and  will  shut  down  appliance  if  internal 

heat exceeds set temperature.

21.  Vacuum Switch

The  vacuum  switch  is  located  on  the  right  side  of  the 

appliance under the feed motor behind right side panel and 

connects to the drop tube with a hose.  This switch turns 

the feed system on when vacuum is present in the firebox. 

The vacuum switch is a safety device to shut off the feed 

motor if the exhaust or the heat exchanger system is dirty,  

plugged or if the firebox door is open. 

22.  Wall Control Thermostat

The appliance is designed to run on a custom designed . 

volt DC thermostat wall control.  It will not operate on any 

other wall control.  Refer to the instructions supplied with 

the appliance located in the component pack.
