PRESSURE GAUGE
The pressure gauge on the control fascia panel indicates the central
heating system pressure. If the normal running pressure is seen to
decrease from the original installation pressure of around 1 bar (cold)
over a period of time, then there may be a water leak. In this event
consult a CORGI registered installer.
Do not attempt to fire the boiler if the pressure has reduced
to zero from the original setting.
To ensure continued efficient operation of the appliance, it is recommended
that it is checked and serviced as necessary at regular intervals. The
frequency of servicing will depend upon the particular installation
conditions and usage but in general once a year should be adequate. It is
law that any service work must be carried out by a competent person such
as British Gas or other CORGI registered personnel.
GENERAL CARE
The front panel, being a powder coated white finish should be cleaned
with a damp cloth and mild detergent. Do not use abrasive cleaners.
ROUTINE SERVICING
WARNING
If a gas leak is suspected or exists, turn the gas OFF at the
incoming mains (adjacent to the meter). Do not operate any
electrical switches. Do not operate any electrical appliances.
Open all windows and doors. Do not smoke. Extinguish all
naked lights. Phone the Transco 24 hour emergency number
immediately on 0800 111 999. (Do not call from a mobile
phone).
The boiler is fitted with a condensate trap.
The condensate drain point must not be modified or blocked (see
section 4.6 of the installation manual).
Like all condensing boilers this appliance will produce a plume
of condensation from the flue terminal. This is due to the high
efficiency and hence low flue gas temperature of the boiler. It
is normal and not a fault indication.

CONTROL OF WATER TEMPERATURE
DHW:
Hot water temperature is limited to a maximum of 55°C at low draw-off
rates and is not adjustable.
CH:
Adjustable via the CH temperature control knob to give radiator
temperatures of between 30°C and 80°C. To operate the boiler more efficiently it
is recommended to set the CH temperature about half way (between '+' and '-').
To avoid setting the control knob temperature to ‘STANDBY’ in summer when CH
is not required, switch the clock over-ride switch to the OFF position OR turn the
room thermostat off.
Note:
If the digital display shows a flashing '
C
' the
boiler is in a service mode and the boiler will fire
continuously at minimum input. (See fig.2)
This setting is for the convenience of the
Service Engineer ONLY.
5.3
TO TURN THE BOILER OFF
For short or long periods
Switch the programmer and/or room thermostat switch to the
OFF
position.
Note:
The appliance is fitted with a frost protection device. In the event
of very cold conditions, the pump may operate and the boiler light for a
few minutes to protect the appliance from potential frost damage. This
can only function if the gas and electricity supplies are maintained and
the control knob on the appliance is set to the ‘STANDBY’ position.
This function automatically operates the boiler when the heating system
water reaches temperatures below 5°C.
If either the gas or electricity services are to be isolated during a period
when frost is likely, the water circuits must be drained.
5.4
BOILER OVERHEAT PROTECTION
The appliance is fitted with two water temperature thermisters located on
the flow and return pipes. In the event of overheating, the boiler will shut
down and the digital display will show '
1
'. Allow the boiler to cool, then
briefly turn the control knob fully anti-clockwise to the RESET/STANDBY
position and then back to 'ON' within TWO seconds.
If the fault persists, consult a CORGI registered installer.
5.5
DIAGNOSTIC DIGITAL DISPLAY
Refer to Fig. 2
If the digital display shows an error code between 1 and 4 the boiler is in
lockout condition
To RESET the boiler turn the control knob fully anti-clockwise to the
RESET/STANDBY position and then back to 'ON' within TWO seconds.
For fault finding refer to diagnostic chart shown on the previous page,
together with the notes given in sections 8.3, 8.4 and 8.5 of the boilers
installation manual.
