INSTALLATION

Control Board Installation

The Winslow PI40 insert is shipped with the control board wrapped and
placed behind the firebox. To install the control board, unwrap it and
the right side surround panel found in the surround kit. There are four
prongs protruding from the surround. Place the two slots in the bottom
and the two holes in the top of the control board over the four prongs
on the surround panel. Install the surround panels following the instruc-
tions on Page 10.

Venting

This fireplace insert is approved for venting with Type L and Type PL
pellet vent pipe (listed to UL 641 and ULC S609) or listed pellet flex liner
(2100HT [degree F.] liner listed to UL 1777 or ULC S635). We recom-
mend the use of venting products manufactured by Security Chimneys
International. The insert's flue collar is 3" in diameter. The insert's com-
bustion blower pressurizes and pushes flue gases out the pellet pipe. All
pipe joints should be locked together or screwed with three screws if the
pipe does not have a locking system. The pipe joints can be sealed with
high temperature silicone if there is a possibility of flue gases leaking
into the living area. The pipe should be fastened with three screws to the
insert's flue collar. The longer the run of pipe and the more elbows used,
the greater the resistance to the flow of flue gases. Four inch diameter
pellet pipe is recommended for pipe runs greater than 15 feet or when a
number of elbows are used. A 3-4" increaser can be used to connect the
4" pipe to the 3" flue collar. The outside air pipe may run up the chimney,
horizontally, or down provided the structural integrity of the fireplace and
chimney system are maintained. DO NOT INSTALL A FLUE DAMPER IN
THE EXHAUST VENTING SYSTEM OF THIS UNIT. DO NOT CONNECT THIS
UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

Vent Termination Requirements:

If the insert is not vented vertically, the following apply:
1. Do not terminate the vent in any enclosed or semi-enclosed areas
such as a carport, garage, attic, crawlspace, narrow walkway, closely
fenced area, under a sundeck or porch, or any location that can build
up a concentration of fumes such as stairwells, covered breezeway,
etc.
2. Vent surfaces can become hot enough to cause burns if touched.
Non-combustible shielding or guards may be required.
3. Termination must exhaust above the inlet elevation. It is recommended
that at least five feet of vertical pipe be installed outside when the
insert is vented directly through a wall. This will create a natural draft
to prevent the possibility of smoke or odor during appliance shut
down or power failure and avoid exposing people or shrubs to high
temperatures.
4. The vent should terminate no less than four feet below, no less than
four feet horizontally from, and no less than one foot above doors
and windows, or gravity/ventilation air inlets into the building.
5. The distance between the bottom of termination and grade should be
12" minimum. The distance between the bottom of the termination
and a public walkway should be a minimum of seven feet.
6. Locate the vent termination at least two feet away from combustible
materials such as shrubs, plants, grass, fences, roof overhangs, and
adjacent buildings.
