grates and Firebrick
Lay the two grate inserts into the grate holder as shown.
Divide the spaces between the grates equally and be sure
they are not tight. The spaces are needed for expansion.
The grate inserts can also be installed or removed after the
feeder is in place.
Place the two firebricks on the grate angle and make the two
bolts snug on the adapter plate as shown.
Apply 1 inch flat gasket around the feeder opening and insert
the feeder and adapter plate into the boiler and tighten.
NOTE: You will need a 3/4” socket to do this.
Blower
Remove one of the screws on the intake screen, and install
the blower restrictor plate. Install the blower on the bottom
of the feeder by sliding it into the bracket as far as it will go.
NOTE: The bolt holes on the blower flange are not used.
Control Box
Install the control box on mounting pad provided on the side
of the stoker with (4) #8-32 bolts and nuts.
Plug the gear motor into the top receptacle, and the
combustion blower into the middle receptacle on the control
box. The bottom receptacle is not used.

Push top of hopper under the hopper support, causing the slot
on the bottom side of the support to hook onto the hopper.
The hopper support will spring up slightly for the hopper to
go under. If you have difficulty getting the hopper under, you
can raise the top slightly
The feed motor cover can now be installed.
