or

Quick Cleaning Cycle
Every hour the unit enters a quick cleaning cycle. The cleaning cycle is the same for every operating mode.
The cleaning cycle will last several minutes, and then the stove will return to the current operating setting.
During the cleaning cycle, the feed rate of the pellets decreases and the exhaust fan speed increases.
Shutdown Cleaning Cycle
After the unit runs for five hours, it enters a more extensive shutdown cleaning cycle. The stove cleans the burn
pot by stopping the pellet feed and increasing the exhaust fan speed allowing the fire to extinguish completely.
Once the fire is out completely, the stove will enter a normal startup cycle.
Power Outages
The stove does not have backup power to operate during power outages. If the unit is installed with no vertical
exhaust venting, it may cause smoke to backup into the room. To minimize the potential for smoke entering the
room Hearthstone suggests installing the unit with a minimum of three feet of vertical venting and the use of
outside air intake venting.
Once the power is restored, the stove will return to the operational setting active prior to the outage. If ignition is
required, the stove will enter a special ignition procedure.
If you live in an area that experiences frequent power outages, you can use an aftermarket backup power
supply for this stove, or you can use a generator. Contact your dealer for purchase options and assistance.
Frost Setting
This stove is equipped with a frost setting. To utilize the setting, the room sensor must be connected and the
stove must be turned off in the Automatic or Programmable Modes. If the room temperature drops below 42°F,
the stove will automatically turn on at its maximum heat output setting, and then turn off when the room reaches
55°F.
Note: This unit is a supplemental heat source. It will not operate without fuel or electricity therefore
unattended operation time is limited. Use extreme caution with this feature.
