– Turn on the gas su ly.
– Turn the boiler control on, and to maximum. Check the
boiler lights.
– Set the boiler control to the required tem erature for the
maximum boiler flow. Turning clockwise increases the set
oint tem erature.
– Make sure the external controls are fully o erational and
the com lete system is controlled correctly.
1.3.2 To turn the appliance off
The a liance may need to be switched off for short eriods.
If required the boiler control may be rotated to the ‘OFF’ osi-
tion (com letely anti clock wise) which will revent the a li-
ance from o erating in the event of a demand from any exter-
nal controls.
If the a liance is to be switched off for long eriods the boil-
er control should be rotated to ‘OFF’ and the electrical su ly
to the com lete system should be isolated.
If the a liance is to be switched off for a rolonged length of
time during severe cold conditions then it is recommended
that the com lete heating system and a liance is drained to
revent freezing. A service engineer would normally be
required for this.
If a frost thermostat is fitted to the heating system, no draining
of the system is required, leave the a liance switched on and the
tem erature control at its minimum setting and turn any external
timer controls off. This will allow the a liance to o erate via the
frost thermostat and revent the system from freezing.
1.4 MINIMUM CLEARANCES
The following MINIMUM CLEARANCES must be available for
servicing the a liance:
1.5 ROUTINE SERVICING
To ensure continued efficient o eration of the a liance, it is
recommended that it is checked and serviced as necessary
at regular intervals.
The frequency of servicing will de end u on the articular
installation conditions and usage but in general once a year
should be adequate. It is the law that any service work must
be carried out by a registerd erson (C.O.R.G.I.).
1.6 GENERAL IN ORMATION
1.6.1 Appliance overheat thermostat
The a liance is fitted with a safety cutout thermostat. In the
event of the a liance overheating this will revent the a li-
ance from functioning.
If this occurs, both the overheat warning lam and the ignition
lock out indicator will illuminate. Allow the a liance to cool,
de ress the ignition-reset button and turn the rotary control
to ‘OFF’. Switch the electricity su ly to the a liance off, this
will reset the overheat warning lam . Switch the electricity
su ly to the a liance on and reset the rotary control to its
original osition. If the external controls are calling for heat,
the a liance will erform an ignition sequence and the burn-
er will light.
If the situation is re eated, turn off the electrical su ly and
consult your installer or a service engineer.
1.6.2 Electrical supply
An interru tion in the electrical su ly whilst the burner is
alight may cause the overheat thermostat to o erate. If this
ha ens and the electrical su ly is restored whilst in this
condition, the warning lam s may illuminate after an ignition
sequence (refer to section 1.6.1). However should the electri-
cal su ly be restored after the a liance has cooled, normal
o eration will be restored.
1.6.3 Cleaning
Use only a dam cloth and mild detergent to clean the a li-
ance outer casing. Do not use abrasive cleaners. It is recom-
mended to clean the outer case when the a liance is cold.
1.7 SA ETY
It is essential that the instructions in this book are strictly fol-
lowed for the safe and economical o eration of this a liance.
The a liance functions as a fan assisted balanced flue unit.
The flue terminal MUST NOT BE OBSTRUCTED under any cir-
cumstances. If damaged, turn off the a liance and consult
the installer, service engineer or gas su lier. If it is known or
sus ected that a fault exists on the a liance it MUST NOT be
used until a com etent erson has rectified the fault.
WARNING: I A GAS LEAK IS SUSPECTED OR EXISTS,
TURN O THE GAS SUPPLY TO THE APPLIANCE AT THE
GAS SERVICE COCK. DO NOT OPERATE ANY ELECTRICAL
SWITCHES. DO NOT OPERATE ANY ELECTRICAL APPLI-
ANCES. OPEN ALL WINDOWS AND DOORS. DO NOT
