appliance has been factory set and
does not require adjustment. To
check the main burner pressure
connect the U-Gauge as follows
depending on the gas type.
For natural gas appliances:
●
Slacken the sealing screw (
1
) at
test point on the gas valve and
attach one arm of a U-gauge (
2
) to
the test point.
●
Remove plastic sealing plug and
connect the other arm to the
combustion chamber sensing
tube (
3
).
For LPG appliances:
●
Slacken the sealing screw (
1a
) at
test point on the burner inlet gas
pipe and attach one arm of a
U-gauge (
2a
) to the test point.
●
Remove plastic sealing plug and
connect the other arm to the
combustion chamber sensing
tube (
3a
).
Set the DHW temperature control to
maximum and fire the boiler at full
rate by fully opening a hot water tap.
Check that the burner pressure is as
the maximum shown in table G2.
Measure the domestic hot water mode
burner operating pressure (mbar), the
heat input (kW), the inlet and outlet
domestic hot water temperatures (°C)
and flow rate (l/min) and record
details in the boiler logbook.
After completion of all tests tighten
sealing screw, replace the sealing
plug and check all test points for
