2.04 Central heating adjustment
(not normally required)
To adjust boiler heat input (thus also regulating heat output to the central heating water) simply adjust
the main burner via the electronic control board (fig. 4 and 5).
The diagrams indicate the variation in heat output to the water as burner working pressure is varied.
Adjusting boiler output to the actual requirements of the central heating system will minimise boiler
cycling thus saving fuel, varying the output has virtually no effect on the efficiency and combustion
characteristics of the boiler.
