Lighting the boiler

Some products incorporate an anti cycling
time delay. It is normal when first switching
the boiler on for the boiler to operate on heat-
ing for a few seconds then switch off. After
3-4 minutes has elapsed the boiler will then
re ignite and operate perfectly normally. The
ignition delay cycle does not prevent normal
operation of the boiler to provide d.h.w.
If external controls are fitted (e.g. Timeclock,
room thermostat) ensure they "call for heat".
• Turn on the electricity supply to the boil-
er, switching on the fused spur isolation

The boiler will now go through an ignition
sequence and the burner will light.
If after four ignition attempts (about four
minutes) the boiler fails to light, the boiler
will go to lockout and the lock-out signal
lamp 6 will appear.
To reset the boiler press and release the
boiler reset button 7.
For the first lighting up and following main-
tenance procedures for the gas supply, it
may be necessary to repeat the resetting
operation several times so as to remove the
air present in the pipework.
After five consecutive resetting attempts the
reset button is inhibited. To restore its func-
tion it is necessary to switch the boiler off
and on from the electrical mains, using the
fused spur isolation switch fitted adjacent to
the appliance.
