INSTRUCTIONS FOR USE
If you experience any diffi culty with the
operation of the boiler, switch off the
boiler immediately at the fused spur iso-
lation switch and contact your Installer
or an approved Service Engineer.
Air introduced into the boiler during this fi ll-
ing process will vent through the automatic
air purger fi tted to the boiler. You may also
fi nd it necessary to vent air from your radia-
tor circuit using your radiator key, however
be aware that excessive venting will cause
the pressure in the system to drop.
Always ensure that the pressure gauge is
set at the required pressure.
