• Adjust heating temperature to maximum .
• Check that any external controls, if fitted, are calling for heat
(set room thermostat to maximum).

the gases contained in the water of the central heating system.
• Gases driven towards the boiler will be automatically released
through the automatic air vent.
• The gases trapped at the highest point of the system must be
released by bleeding the radiators. Check the burner gas rate
required, ten minutes from lighting. Refer to Data Label on
electrical controls box. Should there be any doubt about the gas
rate it should be checked at the meter.
On reaching maximum temperature, the boiler should be turned
off and the system drained as rapidly as possible whilst still hot.
• Refill system to a pressure of between 1 and 2 bar and vent as
before.
• Restart boiler and operate until a maximum temperature is
reached. Shut down boiler and vent heating system. If necessary,
top up heating system and make sure that a pressure of at least
1 bar is indicated when system is COLD.

of the boiler it is recommended that it is checked and serviced
at regular intervals. The frequency of servicing will depend upon
the installation conditions and usage, but in general, once a
year should be enough.

Safety (Installation and Use) Regulations, Section 35, which
imposes a duty of care on all persons who let out any property
containing a gas appliance.
It is the Law that any servicing is carried out by a competent
person.
Advise the user of the precautions necessary to prevent damage
to the system, boiler and the building, in the event of the heating
system being out of use during frost or freezing conditions.
Advise the user that the permanent mains electrical supply
SHOULD NOT be switched off, as the built in frost protection
and pump saver program would not be operable.
Reminder, leave these instructions and the 'Benchmark' logbook
with the user.
