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.
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.
Burner Installation
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.
The combustor shall not extend beyond the inside of the
furnace wall more than 1”. Beyond this length it is necessary
to add a spacer on the outside of the furnace to keep the
end of the combustor within 1” of the furnace wall.
CAUTION:
If the combustor is shorter than the furnace wall thickness the
combustor should be recessed into the wall. To prevent refractory
overheating, a 45° chamfer should be applied.
