CAUTION:  Always  ensure that plated surfaces  are clean and 
free of  fingerprints  before  lighting the  insert.    Fingerprints 
will leave permanent blemishes if left on plated surface when 
lit.  When installation  is complete, the trim should  be gently 
cleaned with  soft cloth and either alcohol or glass cleaner.  Do 
not overtighten nuts, overtightening can create visible dimples 
on the plated surface.
To Install Door Trim:
 1. Remove the trim pieces and hardware from its packaging and ensure 
that all pieces are present before beginning installation. Take care not to 
scratch  finished surfaces.
2. Open right and left side door.  The side doors swivel open towards the 
back of the insert. See Figure 16. 
3. Open front door. Put trim in place by inserting trim studs into the cor-
responding holes in the door (Figures 14 and  15). The top piece of 
trim will only fit in one direction, but the bottom piece can be installed 
incorrectly. When placing the bottom piece of trim,  make sure there 
is a 9/16” gap between the top of the trim piece and the glass in the 
door. See Figure 18.

Outside Air Installations
Connecting the Winslow PI40 insert to outside combustion air is optional, 
except in mobile home installations and when required by local building 
codes. The fireplace insert’s air intake will accept 2” ID pipe to accommodate 
outside air installations. The air intake on the exterior of the home should 
always be located substantially below the flue termination and terminate 
with a cover to keep out weather and pests. The outside air pipe may run 
up the chimney, horizontally, or down provided the structural integrity of 
the fireplace and chimney system are maintained.
Thermostat installation
The Winslow PI40  insert can be  operated manually  or by thermostat. 
The insert comes from the factory wired to operate manually, see control 
board operation on Page 18. A low voltage thermostat can be  installed 
on the insert. To install the thermostat:
1. Unplug the insert from the electrical outlet. Open the right side door 
and lift out the control board from its retaining  brackets. Locate the 
light green wiring block at the bottom back of the board (see Figure 
13), loosen the two  screws B at the back  of the block, and  remove 
the U shaped jumper wire A protruding from the block.
2. Insert a wire from the thermostat into one of the slots from which the 
jumper wire was removed. Repeat this process for the other thermostat 
wire.
Retain the jumper wire for  future reinstallation. See Page 18   for ther-
mostat operation instructions.
IMPORTANT NOTE:  Install the thermostat per the manufacturers 
instructions, provided with  the thermostat.  Failure  to follow 
manufacturers instructions could result in a  malfunction. Pay 
special attention to the thermostat location requirements. If the 
location requirements are not adhered to the appliance, erratic 
operation or failure may occur.  
Do not mount the thermostat where it may be affected by:
•  Radiant heat from the insert, fireplaces, sun or other heat 
sources.
•  Drafts or dead spots behind doors or in corners.
•  Hot or cold air from ducts.
