FROST PROTECTION
The boiler has a built in frost protection device that protects the boiler from freezing. If the
boiler is to be left and there is a risk of frost, ensure that the gas and electrical supplies are left
connected. The frost protection device will light the boiler when the temperature of the boiler
water falls below 6°C. When the temperature reaches 15°C, the boiler will shut down.
Note: This device works irrespective of any room thermostat setting and will protect the
boiler, but not necessarily the full system. Ensure that vulnerable sections of the circuit are
adequately lagged.
SYSTEM PRESSURE
On installation your installer will have fi lled the boiler and system to its effective working
pressure. The boiler's pressure gauge should be regularly checked to ensure that this pressure
is maintained between 1 and 2 bar. If there is a signifi cant loss in pressure the boiler will lock
out. The system may be re-charged by opening the fi lling loop to charge the system back up to
1.5bar as indicated on the LCD panel. DO NOT OVERCHARGE THE BOILER PRESSURE BEYOND
2BAR AS THE BOILER WILL NOT OPERATE. The fi lling loop, a fl exible hose with two valves,
should be located below the boiler connecting the second pipe on the right to either one of the
outer pipes, see fi gure 11. DO NOT CLOSE ANY OF THE THREE SERVICE VALVES.
DIRECTLY CONNECTING TO THE BOILER. If the boiler frequently loses pressure then your
installer should be consulted. Failure to have leakage repaired may cause corrosion within
your heating system.
OPERATING THE BOILER
Prior to operating the boiler, check that the pressure reading, on the LCD panel, lies between
1 and 2bar.
Set the boiler's 'Central Heating' temperature controls to maximum by turning fully clockwise
and set the external 'Room Thermostat' (if fi tted) to maximum. (To set the room thermostat
refer to its manufacturer's instructions.)
Switch the boiler's functional switch to the
now automatically carry out pre-ignition safety checks before fi nally igniting the burner.
The 'Central Heating' temperature control and 'Room Thermostat' can now be set to the
desired temperature settings.
When a demand for heat no longer exists, the burner will automatically shut down and the
fl ame symbol will be not shown at LCD display, it means boiler at Stand by. The boiler will be
ready for the next heating demand.
CLEANING
The boiler casing may be cleaned with a damp cloth followed by a dry cloth to polish. Do not
use abrasive or solvent cleaners.
