N.
Close Burner Swing Door and secure using (4) 5/8”
flat washers, (4) 9/16” lock washers and (4) 9/16 - 12
x 2” lg. cap screws as shown in Figure 34. There are
(4) points of internal contact around perimeter of BSD
and Front Section. These stop the door travel when
tightening hardware to prevent excess compression
of rope gasket. Therefore, continued tightening of
hardware will only bend the hinge pockets. Use a hand
wrench to tighten the hardware. Use an alternating
tightening method from right side to left side cap
screws to secure door until sealed without applying
excessive torque. Never tighten hardware on either side
100% without using the alternating tightening method.
Failure to follow the prescribed procedure could cause
thread damage, a crack in the casting or a leak in the
door seal.
O.
Mount Burner Adapter Plate to Burner Swing Door,
refer to Figures 35 and 36.
Also, refer to Burner Installation Manual for mounting
instructions specific to each burner (provided with
burner).
