1. It is the responsibility of the installer to instruct the user in the
day to day operation of the boiler and controls and to hand over
the completed Benchmark Checklist at the back of this manual.
2. Set the central heating and hot water temperatures to the
requirements of the user. Instruct the user in the operation of the
boiler and system. The temperature on the boiler rotary knob must
be set to a higher temperature than the cylinder thermostat to
achieve the required hot water demand.
3. Instruct the user in the operation of the boiler and system
controls. Demonstrate to the user the action required if a gas leak
occurs or is suspected. Show them how to turn off the gas supply
at the meter control, and advise them not to operate electric light
or power switched, and to ventilate the property.
4. Show the user the location of the system control isolation
switch, and demonstrate its operation. Advise the user that they
may observe a plume of vapour from the flue terminal, and that it
is part of the normal operation of the boiler.
5. When installed on a sealed system the method of repressurising
the primary system should be demonstrated.
1. Switch on the boiler at the fused spur unit and ensure that the
time control is in the on position and any other controls (i.e.
room thermostat) are calling for heat. The boiler will begin it start
sequence.
1. If the CH system is shut down for remedial work requiring
either the electrical power to be switched off or the gas supply to
be turned off then any frost protection present will be inactive.
2. Switching off the boiler's power supply or turning off the gas
supply will disable any frost protection that has been
incorporated into the control system.
See Section 4.4 Control Panel Description
1. To prevent radiators and pipework from freezing in areas
where there is a risk of frost (e.g. a garage or storage room), a
frost thermostat should be connected to the control system.
The following arrangement is recommended:-
Utilise a room frost thermostat in conjunction with a
pipe thermostat. The pipe thermostat should be located
on the primary return close to the boiler.
The operating parameters for this boiler are factory set.
