P61A Pellet Stove
These units are pre-tested at the factory with exactly
120 Volts A.C., 60 Hz. They are checked and adjusted
for rebox tightness, gasket leakage, motor operation
and igniter operation. The P61A is then factory set at a
mid-point adjustment and in most cases will not need any
adjustments.
The control board on the P61A is equipped with
a low draft adjustment port. Located on the control
face just to the right of the igniter light. This voltage
adjustment is provided to allow the unit to be adjusted
for the household voltage where the unit is going to be
in permanent operation.
The low draft voltage should be adjusted to achieve
the most efcient burn on low burn or "maintenance".
This voltage adjustment allows the installer to change
the low voltage set point approximately 10 volts. This
adjustment should be done by the installer during set
up because a draft meter reading is to insure
proper set up.
If the unit is not adjusted properly, it does not cause
a safety concern. If the unit is adjusted too high, only
efciency is lost. If the unit is adjusted too low, the low
draft pressure switch will not allow the feed motor or the
igniter to operate.
The small straight
screwdriver slot is
plastic; therefore,
the unit can be
adjusted while in
operation.

A simple draft test should be performed after
completing the ue pipe installation. To record the results
for future reference:
1. Plug unit into a 120VAC, 60 HZ outlet.
2. Close the hopper lid, front view door, and the ash pan.
Neither pellets or a re are required for this test.
3. With the mode selector in the "OFF" position, turn
the feed adjuster to "TEST".
4. Record the high draft_____in W.C. (Normal is -.50
to -.60) The control will be on the High Draft for a total
of 1 minute.
5. After the minute, the combustion motor will go down to
low draft and the distribution blower will go on high. Allow
approximately 15 seconds to pass for the combustion
motor to slow before checking the low draft.
6. If the low draft is between -.35 and -.45, record the
reading _____ in W.C. If the reading is higher, slowly
turn the set screw counter-clockwise until the draft
lowers. If the reading is lower, very slowly turn the set
screw clockwise until the draft increases.
