of
the burner, it
is
impo

ant that the electrode be positioned
properly over the top of the burner. The electrode was set at the factory for proper
ignition and
should not need further adjustmen
t;
however, if you should experience
inconsistent ignition, reposition
electrode as
fo
ll
ows:
Equipment
needed: flashlight, black felt-tip
pen
, needle-nose pliers, measuring tape
NOTE: Furnace must
be
removed. (See instructions for removing unit.)
1.
Remove burner from combustion chamber by removing six (6) screws which
attach the burner to the chamber and air
baffles (plates

Using a black felt-tip pen, mark a line along top
of
burner 3/16'
in
