ROUTINE CLEANING
Unplug and Ensure Stove is Cold Before Performing
Any Maintenance Work.
The following areas need to be inspected and cleaned
during Routine Cleaning:
• UltraGrate (burn grate)
• Ash Pan
• Heat Exchange Tubes / Tube Scraper
• Photoeye
• Exhaust Passages and Vent Pipe
• Ash Clean-out Ports
• Gaskets
• Window Wash
• Rear Stove / Insert Compartment
UltraGrate
 (Burn Grate for All Models)
The UltraGrate  should be inspected periodically to as-
sure that the air holes have not become clogged with ash
or clinkers. The UltraGrate
 can easily be cleaned with
the grate scraper / ash pan tool, or it can be removed for
cleaning. It is very important to monitor the ash build up
under the UltraGrate
, as excessive amounts of ash will
block combustion air from entering the grate, causing
pellets to pile-up in the grate. The grate cleaning proce-
dure is the same for all models.

ing on the amount of fuel consumed. To access follow

scraper tool, lift the UltraGrate® out and sweep the
