P68 Pellet Stove

The P68 Pellet Stove is capable of manual operation. This also allows the operator 

to manually control operation during an emergency (i.e. igniter failure, or when using 

certain generators or other auxilliary power source.)

The  unit  can  be  switched  between  "AUTO"  and  "MANUAL"  at  any  time  during 

operation.

igniter Switch to "Manual"

room temperature Mode

The fire will have to be lit with starting gel and a match, 

or started automatically, see "Automatic Operation" on 

Page 15. Turn to "Manual" position after the ignition 

cycle begins.

The difference between "AUTO" Room Temperature 

Mode and "Manual" Room Temperature Mode is that 

the fire will not go out as the room temperature goes 

above the control board setting. The unit can only go to 

low burn and will remain there until it runs out of fuel or 

until more heat is needed and the feed rate increases. 

Feed rate adjustments and dial settings are the same 

as "AUTO" settings. The blower will shut off completely 

if the temperature on the ESP is too low. 

igniter Switch to "Manual"

Stove temperature Mode

The advantage of this mode is to allow the operator 

to have a large viewing fire without blowing extra heat 

into the room.

During operation, with the temperature dial set at #4 

or less, the distribution fan will not operate. A #4 on 

the temperature dial and a #5 on the feed adjuster is 

approximately 80% output. It is not necessary to operate 

the  distribution  blower  below  this  point. This  control 

setting allows a higher burn rate (a larger viewing fire) 

without an excess of hot air blowing into the room.

An  example  of  when  to  use  the  Manual  Stove 

Temperature Mode is if you want to watch a large fire 

and the room is already  up to temperature. The Stove 

Temperature Mode allows you to have a larger fire and 

a lower sound level, without the distribution blower.

note:  during  the  use  of  this  mode,  if  you 

keep  increasing  the  temperature  dial  setting  to 

increase the fire size, the distribution blower will 

automatically come on when the eSP temperature 

reaches 350

o

 F, or 81% output.

Manual  ignition/oPeration

Room Temperature Mode: 

This 

setting, see below, will produce a 

room temperature of 70 degrees 

with  the  distribution  blower  at 

medium speed.

This  setting  will  produce  a  large  viewing  fire 

without a distribution blower operating.
