ables).

ROUTINE CLEANING
Stove will need to be shut off and cooled enough to han-
dle before routine cleaning is performed. All ash removal
and cleaning should be done while stove is cold. Always
disconnect power before doing any routine cleaning.
Proper Disposal of Ashes
Ashes should be placed in a metal container with a tight fit-
ting lid. The closed container of ashes should be placed on a
non-combustible floor or on the ground well away from all
combustible materials pending final disposal. If the ashes
are disposed of by burial in soil or otherwise locally dis-
persed, they should be retained in the closed container until
all cinders have thoroughly cooled.
The following areas need to be inspected during Routine
Cleaning:
• UltraGrate
TM
• Ash Pan
• Ash Trap and Baffles
• Heat Exchange Tubes
• Exhaust Passages and Vent Pipe
UltraGrate
TM
The UltraGrate TM should be inspected periodically to assure
that the air holes have not become clogged with ash or
clinkers. The UltraGrate
TM can easily be cleaned with the
grate scraper tool, or it can be removed for cleaning. It is
very important to monitor the ash build up under the Ultra-
Grate
TM , as excessive amounts of ash will block combus-
tion air from entering the UltraGrate TM , causing pellets to
pile-up in the UltraGrate TM . The ash build-up under the Ul-
traGrate TM is easily dumped into the ash pan by pulling out
the ash slide weekly as shown below. The UltraGrate TM
cleaning procedure is the same for all models.
UltraGrate TM
Minimum Frequency of 1 day – 2 weeks
ASH PAN (Advantage II-T C FS)
The ash pan will have to be emptied periodically, de-
pending on the amount of fuel consumed. To access fol-
low steps one through four:
1. Open the glass door, then, using the ash pan / grate
scraper tool, lift the UltraGrate TM out and sweep the
top ash into the pan below.
2. Remove the ash pan cover located below the door
by pulling forward until magnets release.
3. Pull the ash pan door knob and swing open.
4. Remove the ash pan using the ash pan / grate
scraper tool. (See picture below)
5. Place ashes into a non-combustible container. When
finished, close the glass door and slide the ash pan
back into the stove and close the ash pan door. Re-
install ash pan trim piece.
