EOGB X500 - Air Damper Adjustment for Output

Revision 1 01/01/16
Burner Operation and Commissioning
8.6 Low and high output air damper adjustment
The air damper is set in the factory. This regulation is purely indicative.
Each installation however, has its own unpredictable working conditions: actual nozzle output; positive or nega-
tive pressure in the combustion-chamber, the need of excess air, etc.
All these conditions may require a dierent air damper setting.
The X400 comes tted with the LOW output air adjuster, this is to be used with a burner output of up to 25kW
(85,000 BTU). If you require a higher output, then t the HIGH output air adjuster.
The X500 comes tted with the HIGH output air adjuster, this is to be used with a burner output of over 40kW
(136,500 BTU). If you require a lower output then t the LOW output air adjuster.
WARNING
Low output adjuster High output adjuster
• To t, simply unscrew the spring loaded securing
screw (see A diagram below).
• Remove air intake and air adjuster (B & C).
• Replace with preferred air adjuster (C or D).
• Ret the air intake and tighten screw.
