Panels
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.
Firebrick
Install the firebrick horizontally on the angle bracket
above the burnpot.
Flame guide
Install the cast iron flame guide on top of the burn pot.
Make sure that the flame guide is fully seated on the
vertical sides of the burn pot and that the back of the
guide rests against the body of the stove.
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. The
principal of this sensor is much like that of a standard
wall thermostat. However, the thermostat is built in to
the circuit board and the optional sensor reads the
temperature from wherever it is located. Because it is
so small, the sensor can be hidden along the trim of a
doorway or even up the leg of a coffee table. The sensor
gets connected directly to two terminals on the back of
the circuit board. Standard 18-2 thermostat wire can
be used to extend the distance to any desired location
(within 25 feet).
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 recommended for consistent temperature
control.
note: since the control is capable of room
temperature operation, it is recommended that a
room sensor be installed to prevent accidental
shut-down. see (4-Blinks) page 15.
