Installing collar to top:
To install hot air attaching
collar, simply bend all tabs right angle under
shroud. This may be possible with thumbs, if not,
remove top and use small hammer.
CAUTION: Any hot air plenum connection to a fur-
nace must be constructed of metal.
Installing Grates:
Install grates together, slip shaker
lug into hole and place grates into frame. Grate
arch faces upward. Check out grate rotation by
placing shaker handle on grate lug (3/4"). Grates
should rotate freely.
NOTE: Grates are designed to withstand high tem-
peratures, however, should you overfire the fur-
nace you may fuse or melt grates. This happens
if furnace receives too much air caused by leav-
ing the ash and feed doors open, draft fan cover
wide open, and hot coals or ashes are excessive
in ash pan.
