Eclipse ThermJet Self-Recuperative, V5, Installation Guide 208, 2/4/2013
Checklist Before Installation
Air Supply
Provide an opening in the burner room of at least one
square inch per 10,000 BTU/hr (6 cm
2
per 2.9 kW) to
supply the burner intake with fresh, outdoor, combustion
air.
If there are corrosive fumes or materials in the
surrounding air, find an uncontaminated source to supply
air to the burner, 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
• Fuel 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
Prepare the Burner
Several components must be installed on a burner before
it can operate.
Install the igniter in the burner before installing the burner.
See “Step 5: Igniter and Flame Sensor Installation”.
Furnace Wall Preparation
Make sure the furnace wall is capable of supporting the
weight of the burner to be installed. If necessary, reinforce
the mounting area. A round opening approximately 0.5"
(12.7 mm) larger than the OD of the ceramic exhaust tube
must be provided in the casing of the furnace. A larger
hole through the refractory is acceptable and should be
filled with insulation.
To verify proper burner position within the furnace wall,
determine the burner length. Measure from the exhaust
housing mounting face to the tip of the combustor. This is
the burner length. Compare the burner length to the
furnace wall thickness plus the mounting extension length
plus the exhaust tube flange thickness. The burner length
should be shorter by 0 to 1" (25 mm).
Figure 3.1 Burner Position Verification
Minimum gap is
1/8" (3mm). If this
gap is larger than 1/2"
(12mm) fill it with
insulation.
Position the tip of
the combustor tube
approximately in
line with the
furnace wall.
