Grate System Assembly Or Replacement:
The DVC500 grate system is composed
of four pieces: the grate holder, (2)-63 hole
grate inserts, and grate angle. The grate angle
is bolted to the grate holder with (2) 3/8 x 1 1/4
bolts. Before installing the grate holder, 3/8"
round gasket must be checked in the groove on
the bottom side of the grate holder, as shown
in Fig 31. Check to be sure the gasket has not
been damaged.
The grate holder must be installed through
the top door opening after the feeder has been
installed.
Locate the flange at the rear of the grate
holder into the slot on the feeder as shown
below. Bolt the front end down with the 1/4 x
20 allen bolt and nut provided. The rear end
will be locked in place by the flange. Before
tightening the bolt, be sure the grate holder is
back as far as possible and centered side to side
on the feeder opening.
Install grate inserts as shown at left. Seal
joints with high temp furnace cement caulking as
shown in Fig 30. Insert first grate and squeeze
into caulking. Caulk other grate insert, Fig 29,
on edge that joins grate already in place. Insert
caulked grate in remaining space and squeeze
together to make middle joint as tight as pos-
sible. Clean any caulking that has pushed out
from the joints on top of grates. Let caulking
cure before firing.
