Your Insert’s Controls and What They Do
All Montpelier Medium Insert controls are conveniently located
on the front. (Figure 8)
Two controls regulate the performance of your Montpelier
Medium Insert:
The
primary air control
supplies oxygen for the fire.
The variable-speed
fan control
, or rheostat, regulates the
warm air flow into the room.
The Fans
The convection fan delivers a steady stream of warm air into
the room. Use the fan speed control to regulate the flow of air
into the room. A thermal switch will automatically de-activate
the fan when the stove cools down. When starting a fire in
a cold stove, this switch will typically energize the fan within
about 60 minutes depending on wood species and fuel load.
The fan speed should be set at “low” (fully closed) when
operating at low to medium burn rates and may be set
anywhere between “low” and “high” when operating at high
burn rates. (Refer to Figure 10 for fan access)
The Montpelier Medium Insert’s air supply is increased when
the control lever is moved to the left, and decreased when
moved to the right. It may be set anywhere between the
two extremes, depending on the amount of heat desired.
(Figure 9)
To complement the manual setting of the air control, the
Montpelier Medium Insert has an integral convection air
blower that ensures an even delivery of heat at the manual
setting you select.
Primary Air Control
A single air control regulates the amount of heat the fire will
produce and how long it will burn.
The
primary air control lever
is located on the upper left side
on the front of the insert. The lever regulates air for starting,
maintaining, and reviving the fire.
Generally, more air entering the stove makes the fire burn
hotter and faster, while less air prolongs the burn.
WARNING
!
This wood heater has a manufactured-set minimum low
burn rate that must not be altered. It is against federal
regulations to alter this setting or otherwise operate this
wood heater in a manner inconsistent with operating
instructions in this manual.
