Unpacking
Cut straps holding box together and remove box from
skid.
The 38+ is bolted 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.
Installing Rear Cover Panels
The rear cover panels are removed from the stove to make it easier to get at the hold-down bolts.
The rear cover panels are packed inside the hopper and should be installed on the stove as shown. This should be done after the stove is in place and flue is connected.
Firebrick
Install the firebrick horizontally on the angle above the
burnpot.
Rear Cover Panels

Door Assembly/Installation Tips
P38+ Pellet Stove
Assembling the door |
|
Door Glass |
|
|
|
Referring to the diagram, note how the various components of the door system fit together. Lay the load door face down on a soft surface.
Clean the glass and gold door using a nonabrasive cleaner. Install the glass gasket around the outer edge of the front face of the door glass carefully to insure proper sealing. Set the glass pane gently onto the door. Install the hold-down clips and tighten with bolts as shown.
Install door on stove with hinge pins.
Install door handle as shown on the diagram. NOTE: With the flat surface of the paw bolt to the inside of the door.
Turn the paw bolt "in" for approx. (17) turns.
Turn the brass elbow onto the paw bolt approx. (5) turns. Align the set screw with the flat spot on the paw and
tighten.
After attaching the door handle, close and latch the door by turning the handle to the six o'clock position. Does the door rope compress? If not, loosen the set screw, turn the paw bolt one more turn into the door. Repeat as required to achieve a tight door fit.
NOTE: Remember to thoroughly clean the glass and the gold door frame before lighting the stove for the first time.
*Rope the glass carefully to insure proper sealing.
*Apply the rope exactly along the edge of the external face of the glass, not overhanging or pressed too far in from the edge.
* |
Make sharp 90o turns at the corners. |
|
* |
Overlap the ends of the rope at the upper left or right corners. |
|
|
|
|
|
Glass Retainer Clips |
|
|
|
|
*Use the glass retainer clips and screws supplied in the door kit.
*Use a 1/8" Allen wrench to tighten the glass clips to cast door with 10-24 x 3/8" screws supplied.
Paw Bolt
*The paw bolt should be turned into the door from the inside approximately 17 turns.
*With the set screw removed, turn the brass elbow onto the paw bolt approximately 5 turns, or until a 1/16" clearance is achieved between the elbow and the door face (make sure to stop on the flat spot of the paw bolt).
*The set screw on the brass elbow must be aligned to contact the flat spot on the paw bolt, then tighten using a 5/32" Allen wrench.
*After attaching the door handle, close and latch the door by turning the handle to the six o'clock position. During this process observe to see that the door rope is being compressed properly.
*If it does not compress, loosen the set screw and turn the paw bolt one additional turn into the door. Repeat as required to insure a tight seal.

Prior to installing flue pipe, connect a draft meter to the stove as shown in fig. 6 . (The draft meter must have a minimum range of 0-.5). Set control board to "1" on the feed rate dial. Record draft reading here _______ (should read at least
.15" cold. Allow combustion blower to operate for approximately 1 minute before recording or adjusting low draft.). See page 19 for low draft adjustment procedures.
After connecting the flue system, follow the above procedure. However, prior to taking the draft reading be sure all doors and windows in the home are closed. Record the draft reading_______. If this reading is more than .05" lower than the unconnected reading, check for possible restrictions or the need for outside air (see page 7).
