Feeder
Begin assembly by sliding the pusher block with the adjuster rod from the front through the slot shown in Fig. 1. Be sure the
pusher block is turned with the bolt hole to feed indicator side. Next, hold pusher block in the most rearward position and
slide the adjuster tube over the adjuster rod until it bottoms out on the pusher block. Thread the adjuster, then the wing nut
on the end of the adjuster rod.
Put gasket around the opening on the adapter plate. Slide the feeder through the plate and bolt together with two 5/16 x 3/4”
bolts. Next, install the grate holder.
grate
The grate is composed of four pieces: the grate holder, (2) grate
inserts, and firebrick angle. The firebrick 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. 4. Check to be sure the
gasket has not been damaged. Locate the flange at the rear of the
grate holder into the slot on the feeder as shown at left. Bolt the
front end down snug with the 1/4” x 20 allen bolt and nut provided.
The rear end will be locked in place by the flange.
Before completely tightening the bolt, be sure the grate holder
is back as far as possible and centered side to side on the
feeder opening.
