low  draft  voltage  adjustment

These units are pre-tested at the factory with exactly 120 VAC, 

60 Hz. They are checked and adjusted for firebox 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.  

note: the factory low 

draft setting may not be correct for the unit's permanent 

installation conditions.

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. 

note: the line 

voltage varies from area to area and often home to home.

The low draft voltage should be adjusted to achieve the most 

efficient  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 

required 

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 efficiency 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.

low  draft  voltage  adjustment

A simple draft test should be performed after completing the 

flue pipe installation. To record the results for future reference:
1.  Plug unit into a 120 VAC, 60 Hz outlet.
2.  Close the hopper lid, front view door, and the ash pan. 

Neither pellets or a fire 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.

note: in some cases, the draft may not go as low as 

-.35 to -.45 even with the set screw completely counter-

clockwise. ideally, you should just set it as low as 

possible.
