Installing the Igniter
Verify the gap between the center electrode and grounding
rod is no less than 1.5mm and no more than 2.0mm.
Install the igniter into the opening opposite to the flame
supervision in the rear cover (Refer to Figure 2.1)
CAUTION:
Do
NOT
apply any assembly compound to the threads of the
igniter. You can cause bad grounding of the spark plug if you apply grease
to it. Bad ground of the spark may result in a weak spark.
Chamber wall
Provide an opening in the chamber wall at least ½” larger in
diameter than the outside diameter of the combustor.
Provide an accessible pressure tap on the chamber wall to
measure the pressure inside the firing chamber. The
pressure tap should be located near the burner.
Verify that the wall of the chamber is strong enough to
support the weight of the burner. If necessary, reinforce the
area where you plan to install the burner to support the
weight of the burner.
Refractory furnace walls must allow for thermal expansion as
recommended by the refractory supplier – the wall should
apply no stress on the combustor or refractory layer
surrounding the combustor. Expansion joints built into the
furnace wall shall permit the furnace shell, combustor or
burner block surrounding the combustor to move as a unit in
the event of unequal expansion in the refractory wall and
furnace shell.
