Automatic Operation - Harman Stove Company XXV Installation & Operating Manual

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 18.) 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 insure 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.
