The heat exchangers transfer heat from the exhaust system 
into convection air.  There are 2 clean out rods located under 
the heat exchangers.

The heat output switch is located on the lower right side of 
firebox, behind the right face above the reset button.  The 
function of the heat output switch is to regulate the burn rates; 
low, medium and high settings.

The igniter is mounted on the base of the firepot.  Combustion 
air travels over the red hot igniter creating super heated air 
that ignites the pellets. 

The junction box is located behind right cast side of the 
appliance.  The junction box and wiring harness are replaced 
as one component.

The power outlet is located behind the right cast side of the 
appliance behind the thermostat block on the junction box.  
Check the wall receptacle for 120 volt, 60 Hz (standard 
current).  Make sure the outlet is grounded and has the correct 
polarity.  A good surge protector is recommended.  When 
operating with a generator you need at least 600 watts of 
power, or with an inverter at least 800 watts of power available 
for the appliance during the start cycle.

The red call light is located behind the fuse behind the right 
cast side.   The function of the red call light is to indicate that 
the thermostat is calling for heat.

The reset button is located on the lower right side of firebox 
behind right face and below the heat output control switch.  The 
function of the switch is to momentarily open the thermostat 
circuit, which restarts the system.  

The thermocouple is located on top of the firepot inside 
the thermocouple cover (ceramic protection tube). The 
thermocouple sends a millivolt signal to the control box 
indicating the preset temperatures of the green and red lights 
have been obtained.

The appliance is designed to run on a 12 volt AC thermostat. 
The heat anticipator, if present, should be set on the lowest 
setting available. 

The convection blower is mounted at the bottom rear of the 
appliance.  There are 2 impellers, one on each side of the 
motor.  The convection blower pushes heated air through the 
heat exchange system into the room.  

The exhaust blower is mounted on the right side of the 
appliance behind the right cast side.  The exhaust blower is 
designed to pull the exhaust from the appliance and push it 
out through the venting system.  

The feed system is located on the right side and can be 
removed as an entire assembly.  The assembly includes 
the feed motor, mounting bracket, bearing and feed spring 
(auger).  The hollow feed spring (auger) pulls pellets up the 
feed tube from the hopper area and drops them down the 
feed chute into the firepot.  

The firepot is made of high quality ductile iron and has a 
cleaning pull-out rod.  The floor of the firepot opens for 
cleaning when you pull out the rod.  Be sure that the floor 
returns to a completely closed position or your appliance will 
not operate properly.

The fuse is located on the right side behind the control box.  
The fuse will blow should a short occur and shut off power 
to the appliance.

Do NOT open the control box.  This will void the 
warranty.  If you need to plug in or remove the control 
box you must first unplug the appliance.

 

a.  The control box is located on lower right side of 

appliance, behind cast side on top of the junction 
box.

 

b. There is a  light located inside of the control box. The 

internal light will turn green when the appliance has 
reached a temperature of 200

ο

F (93°C) in the firepot. 

and will turn red when it reaches 600

o

F (315°C).

 

c.  There is also an internal blue light located in the upper 

left corner of the control box.  When you plug in the 
appliance the blue light will automatically start blinking 
6 blinks every 10 seconds for 60 seconds and then will 
stop.
