Central Heating
To be able to supply heating, the selector switch 19 fig. 6 must
be turned fully clockwise to ‘ffff position.
This will be confirmed by the green indicator light 0 22 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 Itr/min the central heating
flow switch operates allowing the ignition sequence to begin.
The first stage solenoid 12a fig. 7 and safety solenoid 12c 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 0 23
fig. 6 will light.

After 45 seconds the second stage solenoid 12b 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 9 24 fig. 6 will light.
The central heating flow temperature is controlled by the central
heating control thermistor 16 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 <tTAC 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.
NB
It is possible to override the TAC delay by pressing the RESET
button (25 fig. 6).

Location - F From an internal or external corner 300 mm
- G Above ground roof or balcony level 300 mm
The boiler can be installed on any suitable internal wall. _H From a surface facing the terminal 600 mm
Provision must be made to allow the correct routing of the _f From another terminal facing the terminal 600 mm
flue and siting of the terminal to allow the safe and efficient
removal of the flue products. The appliance may be - J From an opening into the dwelling when
under a car port 1200 mm
installed in any room, although reference must be made to _K Vertically from a terminal on the same wall 1500 mm
the IEE regulations if it contains a bath or shower. A _L Horizontally from a terminal on the same wall 300 mm

been purpose-built or modified for the purpose. It is not M fixed by the flat roof ubbink rolux 4GM flue terminal
_
necessary to provide permanent ventilation for cooling N fixed by a pithed roof ubbink rolux 4GM flue terminal
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
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
- B Below gutters soils pipes or drain pipes
- C Below eaves
- D Below balconies or car port roof
- E From a vertical drain pipe or soil pipe

It may be necessary to protect the terminal with a guard if it is
accessible and could be damaged. Reference should be made to
the Building Regulations for guidance. Suitable guards may be
obtained from the following maufacturer:

Tel: [phone]
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. If vents are installed,
they must communicate with the same room or be on the same
wall to outside air.
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 the 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.

Please check that you are familiar with the installation
requirements before commencing work.(section 6)
Installation
The installation kit included with the flue components
comprise following items :
- Hanging bracket
- A paper template (showing the dimensions of the boiler with
5 mm side clearances, fitting instructions and
commissioning instructions)
- Connection tails
- Screws and wall plugs
- Connection washers
- Pre-piping jig
- Installation manual
Method of positionning the boiler on the wall.
The paper template can be used to ensure the correct
positioning of kitchen cabinets etc. It also details the
commissioning instructions.
The paper template is fixed to the wall and used to locate the
position of the hanging bracket, the centre for the flue hole
and, if required, the fixings for the pre-piping jig.
Drill and plug the wall and secure the hanging bracket using
the screws provided (refer to the paper template drawings~.
Remove the boiler from its packaging as shown in fig. 13 and
remove the outer case as shown in fig.14. 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
Fig. 13
Fig. 14

boiler. Using fig. 15 for reference, connect the gas and water
pipes to the valves located at 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 15) 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.
Fitting the Horizontal Flue
The instructions for the elevated horizontal, 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 610 mm maximum. This
means for rear flueing, the standard kit will accommodate a
maximum wall thickness of 490 mm, and for side flueing a
maximum wall thickness of 477 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 to the terminal.

Connecting of the boiler to the system
- Hinge down the electrical box to gain access to the valves
connections. Push in the tabs (P Fig 19) 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 gaskets provided in the plastic
bag.
