COMPONENT INFORMATION
The following is a list of components and their functions.
Igniter
The Winslow™ PS40 stove comes equipped with an automatic igniter
for lighting the fuel when the stove 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 PS40 stove has a vacuum switch located behind the left
door, fastened to the pedestal base (see D in Figure 52). If a low pressure
is created in the firebox by a leak, opening the front door, a blocked flue,
or unsealed ash drawer, the vacuum switch will sense it and cause the
stove to go into a shutdown mode.
Auger and Auger Motor
The 1.25 RPM auger motor turns the auger, lifting pellets up the auger
tube. The pellets are then dropped down a tube and into the burn-pot.
The auger is controlled by the control board.
Over Temperature Snap Switch (Manual Reset)
(Opens at 225° F) This switch is installed on the convection blower (see F
in Figure 53) and shuts the stove down if it senses excessive temperatures.
This snap switch has a reset button on it and will not allow the stove 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
(see E in Figure 52) and shuts the stove down if it senses no 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 stove gets up to temperature.
