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.
