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.
