Testing - Gas
With the boiler on proceed as follows:
Test for gas soundness around the boiler
gas components using a suitable leak
detection fluid, in accordance with the
current issue of BS6891.
Check the main burner gas pressure at
least 10 minutes after the burner has lit,
refer to Data Label.
If necessary, adjust the gas pressure to
obtain the required setting (screw at rear
of the gas valve) turning anti-clockwise,
viewed from the front, to decrease the
pressure.
Should any doubt exist about the gas rate,
check it using the gas meter test dial and a
stop watch, at least 10 minutes after the
burner has lit, making sure that all other
gas burning appliances and pilot lights are
off.

Turn the boiler thermostat knob fully
anti-clockwise to “Off”. Remove the
pressure gauge from the test point and
refit the screw, making sure that a gas
tight seal is made.
When the boiler thermostat is turned to
the “Off” position, by hand, wait at least
30 seconds before turning “On” again.
There may be an initial smell given off
from the boiler when new, this is quite
normal and it will disappear after a short
period of time.
Refit the electrical controls box cover
with the four screws previously removed.

printed circuit board are an aid to fault
finding, for details refer to Section 11.
