B. Use hand wrench to tighten door hardware and start
with non-hinged side. Use alternating tightening
method from non-hinged side to hinged side to
tighten door equally until sealed without applying
excessive torque. Never tighten hinged side flange
bolt first or tighten either piece of hardware 100%
without using alternating tightening method
described above.
NOTICE
When securing burner swing door, make sure door is
drawn-in equally on both sides.
Failure to follow the prescribed procedure could
cause thread damage to casting or a leak in the
door seal. If hinged side is tightened before the
unhinged side, the hinged side of door cannot
be drawn to provide an air-tight seal. Applying
excessive torque will only cause thread damage.
