NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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.
