12. BURNER MOUNTING PLATE & TARGET WALL
The target wall used on 3-6 section boilers must be
positioned with the fl at side tight against the rear casting and
with the bottom side resting on the fl oor of the combustion
chamber. No glues or fasteners are used to secure the target
wall.
Each boiler is provided with a cast iron burner mounting
plate with an appropriate burner opening and tapped holes
for studs to accommodate burner fl ange. The mounting plate
is furnished with 1/4" diameter sealing rope and an insulation
block which should be installed on the plate before placing
the plate on the boiler. (See Figure 8)

The sealing rope should be placed in the groove on the
boiler side of the plate using adhesive to hold it in place.
The insulation block has a burner opening and a cutout for
the observation opening. Locate the block with the high
temperature facing on the fi re side in the opening in the
front section. The burner mounting plate insulating block
for Beckett burners is installed with the dished side facing
towards the combustion chamber.
Attach the block to the plate with the four 1/4" x 5" machine
screws and 1-1/2" O.D. washers, the washers on the insulation
block side. At the time of burner installation, the hole in the
insulation block may have to be enlarged.
NOTE: Tighten burner mounting plate screws evenly to
slightly compress rope gasket. Overtightening will cause
plate cracking at corners.
NOTE: Most large burners require support to the fl oor. See
burner manufacturer's manual for such specifi cations if
needed.
