Mt. Vernon Pellet Stove
1. Convection Blower Replacement
• Frequency:
As needed
• By:
Qualified Service Technician Recommended
• Task:
a. Allow appliance to completely cool down before
unplugging the appliance.
b. The convection blower is located at the bottom rear
of the stove. If an outside air kit is also installed, you
will first need to remove the outside air flange by
removing the 2 screws using a Phillips head screw-
driver. You do not need to remove the flex pipe from
the flange.
Figure 29.4.
c. Remove the left side curtain by removing the 3
screws securing the panel to the unit. The 3 screws
are located on the side of the stove.
d. Disconnect the wires from the blower. The wires
coming from the wiring harness are purple and white
and the wires coming from the blower are black and
white.
e. The blower housing is attached to the firebox with 4
screws, 2 on each side. Loosen the screws on one
side and completely remove the screws on the other
side. The screw holes are slots and you can
now pull
the housing away from the unit.

B. High Ash Fuel Content Maintenance
• Frequency:
As needed
• By:
Homeowner
• Task:
Poor quality pellet fuel, or lack of maintenance, can create
conditions that make the firepot fill quickly with ashes and
clinkers. This condition makes the appliance susceptible to
overfilling the firepot with pellets which may result in smok-
ing, sooting and possible hopper fires.
Figure 29.1
shows an
example where the firepot overfilled, pellets backed up into
the feed tube and ash has accumulated in the firebox.
Figure
29.2
illustrates an inefficient and non-economical method of
burning of fuel caused by poor quality pellet fuel.
Figure 29.3
is showing the correct flame size when good quality, premium
pellet fuel is burned.
If the ash buildup exceeds the half way point in the firepot
IMMEDIATE ATTENTION AND CLEANING IS REQUIRED.
Follow the detailed instructions found in this section for each
step listed below.
• Shut down the unit by turning down the thermostat and
allow unit to completely cool down. (Do not unplug the unit, it
can cause smoke spillage in the room).
• Pull the heat exchanger cleaning rods.
Section 10.7
• Empty the firepot.
Section 10.2

Section 10.4
• Empty the ash drawer.
Section 10.3
