Maintenance
MAINTENANCE MUST ONLY BE DONE WHEN THE STOVE IS COLD AND THE POWER IS OFF AND
UNPLUGGED.
Ash Removal and Disposal
IMPORTANT:
While the amount of ash generated by this unit is very small compared to log-burning
woodstoves, keeping the unit clean and free of ash is essential for peak performance. Too much ash build-up
can hamper airflow and reduce the unit’s efficiency.
Smoke or fire outside of stove
If you see smoke coming out of your unit into the room and the power has not failed ,
DO NOT UNPLUG THE CORD. DO NOT TURN OFF THE REAR SWITCH. DO NOT OPEN THE HOPPER
OR DOOR TO YOUR UNIT. Immediately press the power button to initiate the off cycle, open the
nearest outside door and windows and wait for all signs of smoke to clear (at least one hour, although the
smoke should dissipate quickly once the door and windows are opened). Stand by with a fire extinguisher just
in case. If there is a soot or creosote fire, follow the above instructions for shutting down the unit and
extinguish fire is possible or call fire department and get all persons out of the house.
Daily Ash Maintenance: Remove material that has accumulated in the burn pot using a metal scraper and a
poker for material that is clogging the burn pot’s holes. Dispose of the scraped ashes from the burn pot and
from inside the frame the burn pot sits on into the ash pan to ensure proper air flow through the burn pot .
Clean the dust on the heat exchanger pipe nightly. Operate the heat exchanger wiper rod back and forth 2-4
times (6” of travel) in order to clean away any fly ash that may have collected on the heat exchanger tubes. To
understand how this works, open the viewing door and look up at the heat exchanger while operating the
wiper bracket. (The diverter bracket can be easily removed for better viewing or a more thorough cleaning with
a brush.)
Weekly Ash Removal:
Clean the burn pot weekly. Shut the unit down and allow it to completely cool. Take out
burn pot, remove ashes and clean holes. Vacuum any ashes that have accumulated in box underneath burn
pot.
Monthly Ash Cleaning: Shut the unit down and allow it to completely cool down and empty the ash drawer.
Use a scoop to reduce mess. Anytime ashes are removed from the stove they should be placed in a
non-combustible container with an airtight lid and should always be placed on a non-combustible surface or
on the ground until completely cooled and free of hot cinders before being disposed of.
Glass:
Clean the door glass and doorframe with a soft, wet cloth and mild cleanser daily. Do not use abrasive
cleaners or attempt to open the door and clean the glass while the unit is in operation or if glass is hot. Allow to
cool, use a soft cotton cloth and mild window cleaner, wood stove glass cleaner, or take a damp paper towel and
dip into the fly ash. This is a very mild abrasive and will not damage the glass. Surface scratches are
acceptable and normal. If the glass becomes cracked in any area, the unit must be shut down and the glass
replaced. Replacement parts must be purchased from your dealer or Nature’s Comfort.
To replace glass, refer to the viewing door parts list on page 25 and diagram on page 26 for the following:
1. Wear leather gloves (or any other gloves suitable for handling broken glass). Carefully remove any
loose pieces of glass from the door frame. Open door and remove gasket by pulling firmly with pliers.
2. Remove all fasteners that were under gasket, take off gasket frame and glass retainers and remove
remaining glass pieces. Dispose of all broken glass properly.
3. Inspect door gasket and glass gaskets that are between door frame and glass. Replace if necessary.
4. Glass dimensions are: (1) 11” x 14” (280mm x 350mm) & (2) 5” x 14” (127mm x 350mm) high
