PP38+ Pellet Stove 3-90-08422R27_09/12
Assembly and Installation
The optional Room Sensor
cable attaches to two bare
terminals on the rear of
the circuit board. These
connections are not polarity
specic.
Unpacking
The P38 is bolted (1/4 x 1" hex head bolts) to the skid
to prevent movement during shipping.
To free the stove from the skid you must remove the
hold-down bolts in the rear of the pedestal base.
Removing rear cover panels
The rear cover panels are secured to the stove with three
bolts each. Two of the bolts need only be loosened, not
removed, to remove the panels. It is recommended that
the rear covers are installed after the unit is in place
and the vent pipe is installed, to prevent contact with
hot or moving parts.

INSTALL EXHAUST VENT AT CLEARANCES
SPECIFIED BY THE MANUFACTURER. Most pellet
vent pipe requires a minimum of 3" of clearance to
combustible materials although some can be installed
at 1" clearance.
The optional room sensor (part #3-20-00906) is a small
temperature sensor on the end of a 60" wire. This sensor
is installed much like a standard wall thermostat. 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.
NOTE: Distances of more than 25 feet from the unit or in
another room are not recommended. The room sensor is
essentialfortheP61A'sexcellentefciency.
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.
