• Check the distance from the electrode to the burner; there should be
a 3/8" gap in between the two. If the existing electrode pins must be
adjusted for proper gap, caution must be exercised, as they will likely
be brittle from exposure to the flame; try to bend them as close to
the burner door insulation as possible using two pair of pliers; one
to support the rod, and one to bend with. New electrodes will be less
susceptible to breakage during adjustment. The metal surface
of the electrodes should also be carefully cleaned with emery cloth.
NOTE: Do not make any adjustments or cleaning with the electrode
still mounted to the burner door, as damage to refractory may
result!
• Dismantle the air gas mixing plate or chamber on the suction side of
the fan and check for fouling. If required, clean the fan blade wheel
and the air gas mixing box.
• Reassemble the burner chamber, making sure there is no moisture on
any of the fireside components.
