Eclipse AirHeat v2.00, Installation Guide No. 135, 7/99

Air Supply

If there are corrosive fumes or materials in the surrounding

air, find an uncontaminated source to supply air to the

burner. Observe ambient temperature limits as stated in

Data 135.

• Combustion Air From Outside Duct

Provide an opening in the burner room of at least one square

inch per 4000 BTU/hr (6 cm

per 1 kW) to supply the

burner intake with fresh, outdoor, combustion air.

• Combustion Air From Inside Duct

There must be a minimum of 18% O

present in the process

air flow to ensure proper burner performance.

Exhaust

Do not allow exhaust gases to accumulate in the work area.

Provide a means for exhausting these gases from the building.

Access

Install the burner so it may be easily accessed for inspection

and maintenance.

Environment

Be sure the burner operating environment matches the

original operating specifications. Check the following items:

• voltage, frequency, and stability of electrical power

• fuel type and fuel supply pressure

• adequate fresh, clean, combustion air

• humidity, altitude, and temperature of the supply air

• presence of damaging corrosive gases in the air

• prevent direct exposure to water.

Note:

Mounting dimensions for all mounting options are found in

Data 135.

• Center the burner in the duct

•

Allow a minimum of 41” (1042 mm) from burner to nearest

point of possible flame impingement at an input of

1,000,000 Btu/hr. (961kW/m) and ∆P air = 1.0”w.c.

See Data 135 for more information about flame lenghts at

other burner settings.

• On burners longer than 36” (914 mm), use a hanger or a

pedestal to support the blower and motor.

• The duct structure must be strong enough to support the

weight of the burner. If necessary, reinforce the mounting

area.
