21 P68 Pellet Stove 3-90-00688R24_06/13
The room sensor is a small temperature sensor on the end of
a 60" wire. This sensor is installed much like a standard wall
thermostat. Because it is so small, it can be hidden along the
trim of a doorway or even up the leg of a coffee table. There
is a remote room sensor port on the rear of the unit for easy
external connection. Use standard 18-2 thermostat wire to
extend the distance to the desired location (50' maximum).
The room sensor should be installed in the location where
you want to control the temperature.
In most installations locating the room sensor behind the
stove near the distribution fan works well because the sensor
monitors the room air being drawn into the distribution fan.
note: Distances of more than 25 feet from the unit or in
another room are not recommended. The room sensor is
essential for the P68's excellent efficiency.
note: it is recommended that the room sensor be
installed, even if only installed on the rear of the unit as a
return air sensor.

Each shield has (3) 5/16" hex head screws. Two (2) that only
need to be loosened, and one (1) that needs to be completely
removed, to allow the shield to slide away from the unit.
note: it is not recommended that the unit be operated
with the shields removed, due to the hot and moving
parts which they protect.
