Control of water temperature
DOMESTIC HOT WATER
The domestic hot water draw-off temperature is normally limited
by the modulating gas control to approximately 60 oC at the
minimum water draw-off rate of about 3.5 litre/min. (0.75 g.p.m.).
It can be varied between 60 oC and 35 oC by adjusting the hot
water temperature control (C).
CENTRAL HEATING
The boiler modulating control automatically maintains the central
heating radiator temperature between 84 oC and 40 oC by
adjusting the variable heating temperature control (B).
If your system includes a room thermostat the heating
temperature control (B) may be left in its maximum position.
If your household includes very young or elderly people you may,
however, reduce this setting, for safety reasons.
To light the boiler (see illustration )
Summer Conditions - Domestic Hot Water Only
Set the main switch (A) to HOT WATER .
Note. Whenever domestic hot water is drawn off, the boiler will
fire to provide hot water at the tap.
Winter Conditions - Central Heating & Domestic Hot Water
Set the main switch (A) to HEATING & HOT WATER .
The boiler will fire and supply heat to the radiators but will give
priority to domestic hot water when required.
NOTE TO THE INSTALLER: LEAVE THESE INSTRUCTIONS WITH THE HOUSEHOLDER
Important Notes
1. THIS APPLIANCE MUST NOT BE OPERATED WITHOUT
THE INNER FRONT SEALING PANEL BEING CORRECTLY
FITTED.
2. Compartment Installations
If the boiler is installed in a compartment then the
compartment MUST NOT be used for storage purposes.
Ventilation provided for boilers installed in compartments
MUST NOT be blocked, and a check should be made
periodically that the ventilation areas are free from any
obstruction.
3. If it is known or suspected that a fault exists on the boiler then
it MUST NOT BE USED until the fault has been corrected by
a CORGI registered installer.
Escape of gas
Should a gas leak or fault be suspected contact your local gas
supplier without delay.
Do NOT search for gas leaks with a naked flame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains use a damp cloth and mild
detergent.
DO NOT use abrasive cleaning materials.
Maintenance
The appliance should be serviced at least once a year by a
CORGI registered installer.
IMPORTANT - DRAINING THE SYSTEM
It is not good practice to drain off radiators to decorate behind
them. In the case of sealed system boilers, such as this, it will
lower the system pressure AND MAY CAUSE THE BOILER TO
STOP WORKING.

absence from home, leave the heating control (B) at a reduced
temperature setting.
For longer periods, the entire system should be drained -
including the domestic water supply .
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF by selecting the OFF
programme at the time control.
