Following replacement the maximum and
minimum settings for natural gas must be
checked to Technical data, section 2.
Check the gas valve settings and re-calibrated by
the following method if required:
19.15 Maximum and Minimum setting
Connect a suitable pressure gauge to the pressure
outlet on the gas valve. (Figure 49)
Remove plastic cover from gas valve adjuster
Create domestic hot water demand by operating a
hot water faucet.
Adjust 10 mm brass nut to gain correct maximum
burner pressure ensuring the inner screw is held
in place with the use of a cross head screw driver
clockwise to increase, anti-clockwise to decrease.
(Refer to Technical Data for pressure settings)
Remove one lead from the modulating gas valve
coil. (Figure 50)
Adjust inner screw to give correct min burner
pressure whilst holding 10 mm nut on maximum
adjuster. Clockwise to increase,
Anti-clockwise to decrease.
Re-connect the lead of gas valve coil.
After adjustment refit plastic cap on gas valve
adjuster and remove gauge and leak test pressure
test point.
19.16 Expansion vessel
Drain the boiler’s hydraulic circuit as detailed in
(19.2)
Disconnect the pipe coupling on expansion vessel
(
Figure 52 ).
Release and remove the nut securing the expansion
vessel to the boiler.
Remove the side panels as described in section 18.4.
Lift the vessel out of boiler from the gap over the
chasis (
Figure 53 ) and fit the replacement vessel to
the boiler in reverse order to removal, ensuring that
sealing washer is fitted to pipe connection before
tightening, replace the washer if necessary.
Using a pressure gauge, ensure that expansion
vessel charge pressure is 0·5bar (7·5psi)
Open the isolating valves on the flow and return
connections, refill, vent and pressurise the boiler
ensuring all joints are sound.
