6.1 Cleaning the Outer case
The painted panels should be wiped with a damp cloth and
then dried completely. DO NOT USE ABRASIVE
CLEANING AGENTS.
6.2 Protection & Precaution
1. The boiler incorporates an integral frost protection feature
that will operate when the selector switch is in the ( )
position. If the boiler temperature falls below 5° C, then the
boiler will operate until the water temperature has been
raised.
2. If a system frost thermostat has been fitted (your installer
will be able to advise you), then to operate correctly and
protect your system, the gas and electricity must be left on and
the appliance set in the central heating mode.
3. The boiler incorporates an integral pump protection feature
which continually monitors the time since the pump last
operated. To prevent seizure, the pump will operate for
approximately 1 minute if it has not run in the last 24 hours.
6.3 To Shut Off the Boiler (Fig. 9)
1. For short periods: Turn the selector switch to the Off
position.
2. For long periods: Turn off the selector switch, electricity
and gas supplies.
If your home is to be left unoccupied for long periods
during cold weather the boiler and whole system should be
drained unless there is additional frost protection.
3. Your installer will advise you about frost protection and
draining the system.
