Operation
Fig. 6
Fig. 7
Central Heating Mode
To be able to supply heating, the main switch 15 Fig. 6 must be turned fully clockwise to position. This will be
confirmed by the green indicator light 18 Fig. 6.
When there is a demand for heating (either from the room thermostat or the external programmer) and the boiler
temperature control is calling for heat. The pump starts and at a flow rate of 4 ltr/min the central heating flow switch
operates allowing the ignition sequence to begin..
The first stage solenoid a fig. 7 and safety solenoid c fig. 7 open together to allow gas to the burner. The ignition sequence
begins and a continuous high speed spark ignites the gas. As soon as a flame is detected the orange indicator bulb 19
Fig. 6 will light. After 45 seconds the second stage solenoid b Fig. 7 opens to allow the full gas rate. If a flame is not
detected, after 8 seconds, the security solenoid closes and shuts off the gas. The red lockout indicator bulb 20 Fig. 6 will
light.
The central heating flow temperature is controlled by the central heating control thermistor e Fig. 7. The boiler has been
designed to minimise cycling and will not attempt to relight for at least 3 minutes after the boiler thermostat has been
satisfied (this «TAC delay» can be set to 30 seconds if required, see maintenance and service guide). When the room
thermostat is satisfied the burner will switch off and the pump will remain running for a further 3 minutes.

Location
The boiler can be installed on any suitable internal wall. Provision
must be made to allow the correct routing of the flue and siting of the
terminal to allow the safe and efficient removal of the flue products. A
compartment or cupboard may be used provided that it has been
purpose-built or modified for the purpose. It is not necessary to
provide permanent ventilation for cooling purposes. Detailed
recommendations are given in BS 5440 pt 2. If it is proposed that it is
installed in a timber framed building then reference must be made to
British Gas Document DM2, or advice sought from CORGI.
Flue
Detailed information on flue assembly is contained in the appropriate
starter pack.
The boiler must be installed so that the flue terminal is exposed to
the free passage of external air at all times. It must not be allowed to
discharge into another room or space such as an outhouse or closed
lean-to. The minimum acceptable clearances are shown below:
- A Directly below an opening, window, etc
300 mm
- B Above an opening, window, etc 300 mm
- C Horizontally to an opening, window, etc 300 mm
- D Below gutters, soils pipes or drain pipes 75 mm
- E Below eaves 200 mm
- F Below balconies or car port roof 200 mm
- G From a vertical drain pipe or soil pipe 150 mm
- H From an internal or external corner 300 mm
- I Above ground roof or balcony level 300 mm
- J From a surface facing the terminal 600 mm
- K From a terminal facing the terminal 1200 mm
- L From an opening in the car port into the dwelling 1200 mm
- M Vertically from a terminal on the same wall 1500 mm
- N Horizontally from a terminal on the same wall 300 mm
- Q Fixed by Ubbink Rolux 4 GM flue terminal
It may be necessary to protect the terminal with a guard. Reference
should be made to the Building Regulations for guidance. Suitable
guards may be obtained from the following manufacturer:
Quinnel Barret & Quinnel Wireworks
Old Kent Road
London SE15 1NL
Tel: 0171 639 1357
Ventilation
The room in which the boiler is installed does not require specific
ventilation. If it is installed in a cupboard or compartment permanent
ventilation is not required for cooling purposes.
Gas Supply
The gas installation and soundness testing must be in accordance
with the requirements of BS 6891.The boiler requires a 22 mm
supply. Ensure that the pipe size is adequate for demand including
other gas appliances on the same supply.
Electrical Supply
The appliance requires an earthed 230V - 50 Hz supply and must
be in accordance with current I.E.E. It must also be possible to be
able to completely isolate the appliance electrically. Connection
should be via a 3 amp fused double-pole isolating switch with
contact separation of at least 3 mm on both poles. Alternatively, a
fused 3 Amp. 3 pin plug and unswitched socket may be used,
provided it is not used in a room containing a bath or shower. It
should only supply the appliance.

Fig. 9
Place the boiler on the wall on the hanging bracket.after removing the
pre-installation jig.
If required, there is space for all piping to pass behind the boiler. Using
fig. 11 for reference, connect the gas and water pipes and the valves to
the base of the appliance using the tails provided. There is a
190 mm space between the valves and the wall to make these
connections.
Provision must be made to fill and recharge the system pressure. This
can be achieved using a filling loop or other methods approved by the
local water authority.
The pressure relief should terminate below the boiler over a tundish or
22 mm pipe (see I fig 12) which should in turn discharge safely outside
the premises. Care should be taken that it does not terminate over an
entrance or window or where a discharge of heated water could
endanger occupants or passers by.
The system should be carefully checked for leaks, as frequent refilling
could cause premature system corrosion or unnecessary scaling of the
heat exchanger
Connecting the boiler to the system (fig. 11)
- Hinge down the electrical box to access to the valves connections.
Push in the tabs (P Fig 13) on either side of the boiler and pivot the
box forward.
- Remove the yellow caps from connecting pipes and connect the
boiler to the taps using washers provided in the plastic bag
2 x fibre washers for the water pipes
1 x washer mesh filter “F” CH return connection.
1 x rubber washer “R” for gas connection.
Provision must be made to fill and recharge the system pressure. This
can be achieved using a filling loop or other methods approved by the
local water authority.
Fitting the Horizontal Flue
The instructions for the vertical and biflux (twin pipe) flue options are
included with the relevant adapter kits.
The standard flue supplied with the appliance is suitable for lengths
from 300 mm minimum to 790 mm maximum. This means for rear
flueing, the standard kit will accommodate a maximum wall thickness
of 600 mm, and for side flueing a maximum wall thickness of 587 mm.
This takes into account the minimum appliance side clearances of 5 mm.
If the fixing is a rear exit flue, the template provides the position of the
centre for drilling the flue hole with a core drill.
If the flue is a side exit installation then calculate the position of the
hole with a slope of 5 mm / metre away from the boiler to the terminal.
The flue should fall slightly to the terminal.

System guidance
The boiler is suitable for sealed systems only. The
maximum working pressure for the appliance is 3 bar. All
fittings and pipework connected to the appliance should be
of the same standard.
Flushing and Water Treatment
The performance of the appliance could be impaired by
system debris or the effects of corrosion. The system must
be flushed thoroughly to remove metal filings, solder,
machining oils and other fluxes and greases before
connecting the boiler. An appropriate flushing and
descaling agent should be used, particulary if it is an
existing system. Refer to BS 7593 (1992) for guidance.
For more information on the use of corrosion inhibitors,
flushing and descaling agents, advice can be sought from
the manufacturers of water treatment products such as:

Tel: 01799 550811
System Controls
The boiler is electrically controlled and is suitable for most
modern electronic time and temperature controls.
The addition of such external controls can be beneficial to
the efficient operation of the system.
The boiler connections for external controls are 230V and
so only controls of 230V or that have voltage free contacts
should be used.
By pass and Pump
The boiler is fitted with a pre-adjusted by pass. Although
adjustment is not normally necessary, the by pass can be
reset by turning screw ( D Fig. 17 ) anticlockwise to open
the by-pass using the chart below for guidance.
If used on a system with thermostatic radiator valves, the
flow rate with the thermostatic valves closed should be
adjusted to at least 300 l/hr.The chart below indicates the
residual head of the pump available for the system.
Expansion Vessel
The expansion vessel is pre-charged to 0.7 bar (10 lb/in2).
The vessel is suitable for systems up to 145 litres
capacity. For systems of greater capacity an additional
expansion vessel will be required. Refer to the chart below
and BS 7074 pt 1 or BS 5449.
Filling Point
Provision must be made to be able to charge the system
on commissioning and to make up any subsequent
pressure loss.
The method of connection must utilise approved
equipment and must comply with the water regulations. A
