PP38+ Pellet Stove

oPeration

The P38+ features two operating modes; 

stove temperature 

Mode

 and 

room temperature Mode

. In Stove Temperature 

Mode, you select a burn rate and the stove will remain at the 

same burn rate regardless of the room temperature. 
In the Room Temperature Mode, with the optional room sensor 

attached, the stove constantly monitors the temperature in the 

room and adjusts the size of the fire and the heat output of 

the stove so that the room is kept at a constant temperature. 

room temperature Mode 

Most consumers use the stove in the Room Temperature 

Mode because it is the easiest and most efficient method 

of keeping the room at a given temperature. In the Room 

Temperature  Mode,  the  Room  Sensing  Probe  constantly 

monitors room temperature. As the weather changes outside 

and your home needs varying amounts of heat to be at a 

desired temperature, the stove will automatically increase 

fire size and heat output so that a constant even temperature 

is  maintained.  If  the  weather  warms  up  and  no  heat  is 

required, the stove will gradually slow down and hold at the 

minimum burn rate. When the house cools down, the stove 

will automatically bring the room temperature to the precise 

temperature you desire.
In the Room Temperature Mode, the distribution blower speed 

can be increased or decreased by adjusting the Room Temp/

Off/Stove Temp dial between L and H. As output of the stove 

increases, the speed of the blower will increase automatically 

to insure that more heat is transferred into the room.

room temperature Mode: 

This  setting,  see  above, 

will  produce  a  room  temperature  of  70  degrees  with  the 

distribution blower at medium speed.
