End of Season Cleaning Of The Accentra Pellet Insert By Harman
During the heating season you should vacuum the inside of the stove 3 or 4 times per burn season or once
per ton of pellets burned (see steps 4 & 5 only). The insert is designed to be very easy to clean and it
should take about 15 minutes to do a good job.
A thorough cleaning is required at the end of each heating season. Keep in mind that
cleaning both your insert and venting system is essential. Cleaning boosts heat output and keeps
the stove running at maximum efficiency. Blazing Hot Stoves does offer annual cleaning services
for their customers or plenty of support for DIY.
TOOLS YOU WILL NEED:
Screw driver Putty knife
Dust Mask & Safety Goggles Paper towels
Shop vacuum w/fine dust (HEPA) filter Rubber gloves (soot really gets into pores)
Standard socket set or nut driver set Drop cloth
Tooth brush Flashlight or drop light
Hearth glass cleaner 4” Flexible chimney brush
TIPS BEFORE YOU START:
Be sure the stove is completely out and cool (and unplugged from electrical power!).
The stove must be completely out before cleaning. Check the burn pot for live pellets, they are a fire
hazard –especially if they get sucked into a vacuum cleaner. Every year there are stories of house
vacuums catching fire by inadvertently sucking up hot ashes. Worse still this can be the source of a
house fire! Remember, hot ashes should be stored in a metal container with a tight fitting
lid. When theashes are completely out they can be used as a soil conditioner for your lawn
or garden. Wear a dust mask! This is important! Don’t be fool hardy when it comes to
protecting your lungs. Wear a mask and protective goggles. Professional chimney sweeps
wear both while performing cleaning tasks.ALWAYS RUN ALL PELLETS OUT OF STOVE AT
END OF SEASON TO AVOID BINDING OF AUGER!!!
STEP #1: PREPARE THE WORK AREA AND STOVE
Lay out your drop cloth to protect your flooring and set out your tools. Remove the ash lip
(figure 1) by pulling it straight out with a tug to loosen it, there is nothing holding it in.
Also, undo the buckles that hold the stove in place (figure 2). Carefully slide the insert out being sure not to
damage any wiring. Protect your hearth with something sturdy like a piece of plywood. Make sure to allow
enough space to work on the back of the stove properly. You must gain access to the exhaust blower and once you
gain access you remove the blower turning the thumb screws(figure3). You have to clean the fans fins gently with
the paint brush then vacuum the blades as well as the cavity in the stove body that the
blower came out of, then reassemble.

STEPS 2 & 3 CLEANING THE ESP PROBE AND FINES COMPARTMENTOMPARTMENT
Remove the side access panel located on back right of insert (figure a above) and vacuum out the compartment
behind it. Be careful not to bend the ESP probe seen on the left side of photo. Any damage to probe caused by
bending or mishandling will result in having to replace item. You need only dust the probe during the service. If
there is excessive carbon build up you can loosen the screw and pull it out of the stove to lightly clean with a scotch
brite pad. Leave that panel open when done; we’ll come back to that later.
Located on the same side of the pellet insert is the fines compartment (figure b & c above) that is accessed by
removing the wing nut. Once removed, vacuum out and then reassemble.
STEP 4: CLEANING THE HEAT EXCHANGER
The above photos show how the heat exchanger is accessed for cleaning. These parts should be removed and
dusted as well as the accordion heat exchanger behind them. You can paint the front of the panels with high heat
paint if you like to cover over any rust. At this time you brush out the exhaust tubes thoroughly with the brush
that came with the stove and then clean out the residue from brushing at the side panel for esp probe that you left
open in step 2 (figure a). Once done you can seal up the esp access panel. Do not reinstall the heat exchanger
covers until step 6 has been completed to avoid a broken glass.
STEP 5: CLEANING THE BURN POT
The bottom cover to the burn pot should be removed. Aggressively scrape the burn pot with the Harman scraper
and then a putty knife or slotted screw driver. Tap on the burn pot with a hammer a few times using medium force
to loosen scale on igniter then inspect to make sure the small air holes are not impacted. Then vacuum burnpot
fully. If any air holes are clogged, use a thin nail or paper clip to clear. Note any unusual wear to burn pot or
auger. Call us if something doesn’t look right.

STEP 6: CLEAN CIRCULATING BLOWER
Located underneath the stove, this can be accomplished with a toothbrush. You will
need an extra pair of strong hands to tip the stove forward while you do this step.
You will usually encounter some dust that has gotten attached to the fan blades. In
extreme cases you may have to remove the fan. Once done you can reinstall the
heat exchange covers from step 4.
STEP 7: CLEANING THE CHIMNEY
You will need a good chimney brush system as pictured below (figure d) and your shop vac with hepa filter. Begin
sweeping your chimney with the vacuum running (figure e) to catch the dust. Repeat the procedure until clean.
Vacuum up the area and reassemble the stove being sure not to pinch any wires along the way. Be careful of your
temp sensing probe as well. Then buckle the latches and reinstall the ash lip. Touch up any of the panels that need
it with high heat paint, wash the glass and just wait for the cold weather.
