Lennox Hearth PI40

Shut Down

Normal - To turn the insert off, turn the heat selector knob to off. The

fans will continue to operate until the control board completes the shut

down cycle.

Power Outage - If the insert loses electrical power for less than 10 seconds

it will continue to operate. If the power loss is greater than 10 seconds,

the insert will go into the ignition sequence and normal operation when

the power is restored. If the insert is connected to a thermostat, the insert

will not start the ignition sequence until the thermostat calls for heat.

Paint Curing

This insert has been painted with a high temperature metallic paint. It

leaves the factory dry to the touch, but completes the curing process as

the insert is used. The paint will cure during the ﬁrst few times the insert

is burned. Also some parts of the appliance may be lightly coated with

machining oil. Ventilate the house during these ﬁrst ﬁrings as the paint

and oil give off carbon dioxide and unpleasant odors. It is recommended

that persons sensitive to an imbalance in the indoor air quality avoid the

insert during the curing process.

Convection Blower Operation

Your Winslow™ PI40 insert comes equipped with a temperature activated

convection blower that extracts heat from the insert. After the insert

warms up, a heat activated switch will turn the fan on. The speed of the

fan varies with the burn rate of the insert. The fan will continue to extract

heat after the insert shuts off and until it is cooled down.

Operating Sounds

As the Winslow PI40 insert is burning, a number of normal operational

sounds may be heard. Pellets can be heard sliding down the auger tube

and into the burn pot. Also, the motor powering the auger can be heard

as the control board calls for pellets. Occasionally a loud noise can be

heard as the auger cuts a pellet in half. When the blowers come on, the

sound of rushing air may be heard. The lower the burn rate the slower

the fan operates. Hourly, the combustion fan will blow at a high speed

to clean ash from the burn pot.

Pellet Fuel

Pellet fuel is made from sawdust and scrap wood from many different

species of wood. Pellets are either 1/4” or 5/16” in diameter and vary

in length (see Fuel Speciﬁcations on Page 5). The Winslow PI40 insert

will burn either diameter pellets. Pellets made from hardwoods contain

more ash than those made from softwoods. Minerals from ash and sand

in the pellets form clinkers under the extreme temperatures in the burn

pot. Try burning various brands of pellets until you ﬁnd one that burns

with minimum ash and clinkers.

Once you ﬁnd a pellet brand that burns well, continue using this brand.

High ash fuel increases the frequency of insert cleaning. Fuel with an

excessive moisture content may jam the auger assembly.

Corn Fuel

Shelled corn can be burned in the Winslow PI40 insert when it is mixed

with wood pellet fuel (see Fuel Speciﬁcations on Page 5). The mixture

can contain a maximum of 50 percent corn. Burning corn may create

more ash than wood pellets and may necessitate the need to clean the

burn pot and glass more frequently.

trafﬁc areas and away from furniture and draperies. Children

and adults should be alerted to the hazards of high surface

temperature and should stay away to avoid burns or clothing

ignition. Young children should be carefully supervised when

they are in the same room as the Winslow PI40 insert. Clothing

or any other ﬂammable material should not be placed on or near

the insert. Any grill, panel, or glass removed for service MUST
