Installing the Flame Sensor
Figure 3.2. Installing the Flame Sensor
1. Install the flame sensor into the 1/2" NPT opening in the
rear cover.
2. Make sure that you connect the flame sensor of a
burner to the electrical circuit of that burner.
■
If you connect the flame sensor of a burner to the
electrical circuit of the wrong burner, then you can
cause fires and explosions.
There are two different types of flame sensors; UV
scanner and flamerod.
■
Adjustments may vary from Eclipse published
values if the flame controls other than those
recommended in the Design Guide are used.
Consult with the engineer who specified the
alternate control for limitations.
UV Scanner
For detailed information on how to install and connect a
UV scanner, refer to scanner information guide.
Installing the Spark Plug
Install the spark plug into the opening in the rear cover.
NOTE:
Do
not
apply any grease to the threads of the
spark plug. You can cause bad grounding of the spark
plug if you apply grease to it. Bad grounding of the spark
plug results in a weak spark.
Combustion Block Installation
For Hard Refractory Lined Furnaces:
• Allow approximately 1/2" (12mm) clearance all
around the refractory combustor.
• Be sure the gasket
is installed between the
burner
and the refractory combustor flange
.
• Install the gasket
between the refractory
combustor flange
and the furnace shell
.
• Support the weight of the refractory combustor
with hard brickwork anchored to the furnace shell
. Fill the 1/2" space between the refractory
combustor
and the three unsupported sides with
soft gasket material
.
