NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
The following is a list of components and their functions.
Igniter
The Winslow™ PI40 insert comes equipped with an automatic igniter
for lighting the fuel when the insert is in the lighting mode. The igniter
superheats air that is pulled through the burn pot by the combustion
blower to light the fuel. The igniter remains energized for the first seven
minutes of the lighting sequence.
Vacuum Switch
The Winslow PI40 insert has a vacuum switch located behind the left door,
fastened to the base (see A in Figure 44). If there is a leak in the firebox
created by the front door being ajar or a blocked flue, the vacuum switch
will sense it and cause the insert to go into a shutdown mode.
Auger and Auger Motor
The 1.25 RPM auger motor (B in Figure 22) turns the auger lifting pellets
up the auger tube. The pellets are then dropped down a tube and into the
firepot. The auger is controlled by the control board.
Over Temperature Snap Switch
(Opens at 225F) This switch is installed on the convection blower (see C in
Figure 44
) and shuts the insert down if it senses excessive temperatures.
This snap switch has a reset button on it and will not allow the insert to
start up until the reset button has been pushed.
Proof of Fire Snap Switch
(Closes at 140° F) This switch is installed on the combustion blower and
shuts the insert down if it does not detect fire in the burn pot.
Convection Blower Snap Switch
(Closes at 120° F) This switch is installed on the right rear of the
firebox and turns the convection blower on when the insert gets up to
temperature.
