Vermont Castings Defiant 1945 Service Manual page 30

22. Install the lower fireback (Fig. 33) . Lean it back against the secondary combustion
parts inside the retainers that position the bottom of the lower fireback. Slight
notches in the bottom edge of the fireback fit behind these cast retainers. Tap the top
of the lower fireback with a mallet to ensure the gasket makes good contact with the
upper fireback. Stand the five firebricks up in front of the lower fireback and join the
firebricks with the retainer clip. Notice the shallow rib on the rear of the air plate
(bottom) that locates the forward edge of the bottom of the firebricks. The bricks fit
behind this rib.
23. Use the left and right wedges to hold the lower fireback/firebricks in place ((Fig. 34).
There is a vertical rib on each left and right edge of the fireback; the wedges must
bear against the fireback between these ribs and the outermost edges of the fireback
while holding the bricks in place. Tap the wedges downward gently with a hammer.
The wedges should be snug, but not tight.
24. Tighten the four bolts holding the upper fireback in place on the back of the stove at
this time (Fig. 28).
25. Set the grate into place on the stove floor. Notice that the narrow side of the slots
faces upward, toward the firebox - this ensures that ashes can fall readily into the
ashpan. Be sure the grate fits flush into its recess in the stove bottom matching up
with the cast bosses on the rear sides of the grate cut out.
