TIBURON PELLET - ASH PAN

OVERVIEW

The Thelin Pellet heater is equipped with a long life DC fan motor
(Figure 1). This motor utilizes a special brush material that may
require additional break in time to properly wear in or seat the
brushes. When the motor is new the brush has a contoured end
that allows for minimum contact initially to facilitate the break in.
As this wears the full width of the brush begins to contact the
armature allowing for proper operation.
We have found that a small quantity of motors have not
immediately seated the brushes. The fan motor condition is easily
corrected by dressing the brushes and reinstalling them.
Testing for a fan motor brush problem is accomplished by two
methods. After recycling the heater by unplugging and
reestablishing power. Press the "Fan" switch only. If the fan runs
push the Clean button and allow the motor speed to increase to
full speed. If the motor appears to be operating at less than full
speed cleaning and seating the brushes will be required.
Included in this kit: (2) P/N 00.0035.0213 motor brushes, (1)
instruction.
Tools Required: #2 Phillips screw driver, medium flat blade, small
flat blade, #200 or fine sand paper strip (Figure 2).
Accessing the motor for brush service: The fan motor is
accessed from the bottom of the heater by removing the phillips
screws on the Fan Cover. Remove the convection fan blade
retention clip and blade. Note the access varies based on heater
model and may require removing the fan motor at the housing
(Figure 3).
Removing the wire harness connections : Using care not to
bend the fan blade, carefully use a flat blade screw driver to help
pry off the red and black motor wire terminals (Figure 3). Note
the brush holders have a corresponding red and black base to
confirm wire connections.
Removing the brush caps: Using a small flat blade screw driver
remove one brush cap at a time. Care should be taken as the
brush holder has a spring that forces to the brush onto the
armature. This spring may cause the cap to pop out unless held
firmly (Figure 5).
Removing and dressing the brush: Remove the brush from the
holder by lifting up and sliding the brush and spring clear (Figure
4). Once the brush is clear hold the brush base and carefully take
a couple of swipes across the brush face with fine sand paper
(Figure 5).
