Safety Features - Harman PELLET P61A Installation & Operating Manual

Maintenance - cleaning the Feeder body
Pellet fines may accumulate in the feeder body over
a period of time; therefore, a yearly inspection and
cleaning of this area must be performed.
To clean out fines:
1. Remove the rear cover panels.
DANGER
Disconnect electrical power to the unit
before removing cover.
2. Remove wing nut and feeder cover on the
side of the feeder.
3. Use a vacuum cleaner to remove all fines.
4. Reinstall feed cover, wing nut, and rear
cover panels.
Hopper Lid
Position Switch
The low draft sensor which is a vacuum differential switch, monitors the negative pressure (draft) in the firebox
through a port on the rear of the feeder. Poor draft will result in an interruption of power to the feeder and the
igniter. Poor draft can be caused by blockage in the exhaust, excessive build-up on the combustion blower fan
blades, a failed combustion blower, or a door or other opening to the firebox not sealed properly. The hopper lid
position switch, located in the right rear corner of the hopper opening, will also interrupt power to the feeder and
igniter if the hopper lid is not closed properly. The circuit board is monitoring the position of these switches. During
a feed cycle, if either of these switches were to open, the feed motor light on the control will stay illuminated
with the power being interrupted by the switch. If the switch opens when the cycle is at rest, the power lights for
the feed motor or igniter will not illuminate. Be sure all doors, including the hopper lid, are securely closed when
operating the appliance.
