Refer to the burner instructions supplied with the heater
for information regarding replacement of individual
components within the burner.
If a burner has been replaced or substituted complete, the
burner must be set up correctly.
1. Remove the burner cover by undoing the two screws
either side of the housing.
Adjustment of the first stage air damper position is
carried out by setting the air damper motor.
2. Loosen locknut (clockwise) and adjust by turning screw
to the required setting as indicated on the adjacent
scale. Once the setting is achieved, tighten locknut
(anticlockwise). (When the burner stops, the air damper
closes automatically under its own weight)
Adjustment of the second stage air damper position is
carried out by setting the air damper indicator.
3. Slightly loosen locknut (clockwise) and adjust by turning
screw till the required setting is shown level with the
locknut. Once the setting is achieved, tighten locknut
(anticlockwise) (may require re-adjust when the nut is
locked down).
Head pressure is achieved by adjusting a screw which
moves a regulating rod. A test point on the burner casting
allows reading the air pressure in the combustion head.
4. Rotate the setting screw in a clockwise or anticlockwise
direction until set point marked on the regulating rod is
level with the outside plane of the head assembly.
Gulliver burners are manufactured to EN 676 standard
and fitted with a singular air pressure switch.
5. Turn the switch at the lowest setting. With the burner
working at the required output, adjust the dial clockwise,
increasing its value until the burner shuts down. Reduce
the value by one set point, turning the dial anti-clockwise.
6. Check for reliable burner operation, if the burner shuts
down, reduce the value by a half set point.
