6.0 Care of the Boiler

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.
