XXV Pellet Stove

3-90-00885R17_02/15

Automatic  Ignition

Room Temperature Mode: This setting, see above, will produce a room 

temperature of 70 degrees with the distribution blower at medium speed.

The XXV is a fully automatic stove that 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 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,  in  the 

AUTO  position,  has  the  added  advantage  of  turning  the 

stove off if no heat is required and turning the stove on again 

when the room temperature drops below your desired room 

temperature set point.

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  adjust 

size  and  heat  output  of  the  fire  so  that  a  constant  even 

temperature is maintained.  If the weather warms up and no 

heat is required the stove will gradually shut down. When 

the house cools down, the stove will automatically bring the 

room temperature to your desired setting
In the Room Temperature Mode you can select either 

Auto 

or Manual modes

 for the 

igniter

 using the igniter toggle 

switch.  When the toggle switch is in the Auto position the 

igniter, located inside the burn pot, is ready to automatically 

light the fire when required.  When the toggle switch is set to 

the Manual position, the stove can be lit manually with either 

a gel or a wax type fire starter.  (see lighting instructions on 

page 20.) With the igniter toggle switch set in the Manual 

position the stove will automatically adjust the heat output, 

but the stove will not automatically shut down if no heat is 

required.  Instead it will go to its lowest setting and remain 

there.   The Manual position on the igniter toggle switch lets 

you light the stove manually, should the igniter fail for any 

reason.    Secondly,  if  you  are  using  the  Harman®  battery 

back up system the Manual setting will prevent the stove 

from  turning  off  and  on  during  a  power  failure,  which  will 

drain the back up battery, and possibly cause damage to the 

back-up or the stove.
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 ensure that more heat is transferred out into the room.  

The distribution blower will shut off as the room reaches the 

set temperature, this will prevent overheating of the room.
