Eclipse Winnox Burner, WX Series, V2, Installation Guide 111, 2/26/2010
Checklist Before Installation
Intake
To admit fresh combustion air from outdoors, provide an
opening in the room of at least one square inch per 4,000
BTU/hr (1.17 kW). If there are corrosive fumes or
materials in the air, then supply the burner with clean air
from an uncontaminated area, or provide a sufficient air
filtering system.
Exhaust
Do not allow exhaust fumes to accumulate in the work
area. Provide some positive means for exhausting from
the furnace and the building.
Access
Make sure that you install the burner in such a way that
you can gain easy access for inspection and
maintenance.
Environment
Make sure the local environment matches the original
operating specifications. Check the following items:
• Voltage, frequency and stability of the electrical
power
• Type and supply pressure of the fuel
• Availability of enough fresh, clean combustion air
• Humidity, altitude and temperature of air
• Presence of damaging corrosive gases in the air
• Prevent direct exposure to water
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.
Ŷ
Connecting the flame sensor of a burner to the
electrical circuit of the wrong burner can result in
a fire or explosion.
There are two different types of flame sensors; UV
scanner and flame rod.
UV Scanner
The UV scanner must be compatible to the flame
monitoring control that is used. Refer to the manual of
your selected control for proper selection of the scanner.
Flame Rod
NOTE:
Only specific burner sizes with alloy or silicon
carbide combustors can use a flame rod (see specific
burner datasheets).
For detailed information on how to install and connect a
flamerod, refer to Info Guide 832.
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 or bad grounding of the spark plug may occur,
resulting in a weak spark.
Ŷ
If flame monitoring controls other than those
recommended in the Design Guide are used
contact Eclipse to determine how the burner
performance may be affected, adjustments may
vary from Eclipse published values. Consult with
the engineer who specified the alternate control
for limitations.
Burner Mounting
Chamber Opening
Provide an opening in the chamber wall at least 1/2"
(12 mm) larger in diameter than the outside diameter of
the combustor (1/4" - 6 mm per side). The combustor
diameter can be found in the Winnox datasheet, series
111.
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.
Figure 3.1 Chamber Opening
Mounting Pattern
Attach eight mounting bolts to the chamber wall. Position
these bolts to match the clearance holes
(C)
on the burner
mounting flange. Refer to Winnox datasheet, series 111.
