INTRODUCTION
The Combitek F 23 E is a wall mounted combination boiler providing central heating and instantaneous domestic hot water.
These instructions should be carefully followed for the safe and economical use of your boiler.
Gas leak or fault
If a gas leak or fault exists or is suspected, turn the boiler and gas supply off and consult the local gas company or your Installer/Service provider.
In case of power supply failure
The boiler no longer operates. As soon as power supply is restored, the boiler will restart automatically.
In case of loss of water in the system
CAUTION. The boiler is installed as part of a sealed system which must only be drained and filled by a competent person.
If the pressure shown on the pressure gauge is less than 1.5 bar the system must be filled up.
Important notice: A central heating system cannot operate satisfactorily unless it is properly filled with water and unless the air initially contained in the piping systems has been properly bled off. If these conditions are not satisfied, air noise will occur within the system and the boiler may fail to operate.
Air in the heating system
Persistent air in the heating system may indicate leaks in the system or corrosion taking place. Call your Installer/Service provider.
Overheating safety
In the event of problem, the overheat safety device causes safety shutdown of the boiler. If this happens, call your Installer/Service provider.

CONTROLS AND LIGHTING Make sure that:
The boiler is connected to the electrical supply. The boiler gas service cock is open. The pressure gauge reads between 1.5 and 2 bar. The boiler is now ready to start.
To start the boiler
Switch on using mains switch (4), see diagram 1. Place switch (2) in the Summer or Winter position
To stop the boiler Place switch (4) to the Off position (0).
Setting to ‘Summer’ mode (Hot water only)
Place switch (2) in the Summer position (see

DRAINING AND FILLING Caution: The boiler is installed as part of a sealed
system which must only be drained and filled by a competent person. Note: If there is persistent loss of system pressure, you must consult your Installer/Service Provider.
HEATING SAFETY VALVE CAUTION: A safety valve with a discharge pipe is
fitted to this boiler. The valve MUST NOT BE TOUCHED except by a competent person. If the valve discharges at any time, switch the boiler off and isolate it from the electrical supply. Contact your Installer/Service Provider.
SERVICING/MAINTENANCE
To ensure the continued efficient and safe operation of the boiler, it is recommended that it is checked and serviced at regular intervals. The frequency of servicing will depend upon the installation condi­tions and usage but, in general, once a year should be enough.

CLEANING
The boiler casing can be cleaned with a damp cloth followed by a dry cloth to polish. Do not use abrasive or solvent cleaners.
INSTALLATION INSTRUCTIONS
INTRODUCTION
The Combitek F 23 E is a wall mounted combination boiler providing central heating and instantaneous domestic hot water.
Note: this boiler requires no fixing jig and has top outlet flueing only ( there is no rear flue option ).
The boiler is of the II2H3+ category for use with Natural gas (G20). To convert to Butane (G30) or propane (G31), the following kit is required.
Gas conversion kit :part number 86161
The boiler has a fan assisted, balanced, flue which both discharges the product of combustion to, and draws the combustion air from, the outside of the building.
BOILER CASING CAUTION: Do not remove or adjust the casing in any
way, as incorrect fitting may result in faulty operation. If in doubt, contact your Installer/Service Provider.
Accessories
A range of accessories are available including, vertical flue components. For further information, contact you nearest stockist.
Gas Safety (Installation and Use) Regulations
In the interests of gas safety, it is the law that ALL gas appliances are installed and serviced in by a competent person in accordance with the above regulations.
Gas leak or fault
If a gas leak or fault exists or is suspected, turn off the boiler and gas supply and consult the local gas company or your Installer/Service Provider.

TERMINAL POSITIONS
The minimum acceptable spacings from the termi­nal to obstructions and ventilation openings are shown in diagram 6 :
Cupboard or compartment ventilation
The boiler can be fitted in a cupboard or compartment without the need for additional per­manent high and low level ventilation
HEATING SYSTEM DESIGN
The combitek F 23 E is compatible with any type of sealed system installation, i.e. radiators, fan convectors etc.
Pipe sectional areas shall be determined in accordance with normal practices, using the pump curve, refer to ‘Technical Data’. The distribution system shall be calculated in accordance with the output requirements of the actual system, not the maxi­mum output of the boiler. However, provision shall be made to ensure sufficient flow so that the temperature difference between the flow and return pipes is less than or equal to 20
o
C. The minimum flow is 500 l/h.
The piping system shall be routed so as to avoid any air pockets and facilitate permanent venting of the installation. Bleed fittings shall be provided at every high point of the system and on all radiators. The total volume of water permitted for the heating system depends, amongst other things, on the static head in the cold condition. The expansion vessel on the boiler is pressurised at 0,5 bar (corresponding to a static head of 5m wg.) and allows a maximum system volume of 140 litres for an average temperature of 75oC and a maximum service pres­sure of 3 bar. This pressure setting can be modified at commissioning stage if the static head differs.
Provision shall be made for a drain valve at the lowest point of the system.
DOMESTIC HOT WATER SYSTEM DESIGN
Copper tubing must be used for the domestic hot water system. Unnecessary pressure losses should be avoided. The domestic hot water supply pressure must be between 0.5 and 10 bar. If the pressure exceeds 3 bar, a pressure reducing valve must be fitted.
Hard water areas
In areas where the water hardness exceeds 200 mg/ litre, it is recommended that a suitable scale reducing device is fitted.
Heating system connections - Pipe Ø 22 mm. Hot water system connections - Pipe Ø 15 mm. Gas connection - Pipe Ø 22mm.
Safety valve discharge WARNING: It must not discharge above an entrance
or window or any type of public access area. Connect the safety valve discharge pipe to the valve, the discharge must be extended using not less than 15 mm o.d. pipe, to discharge in a visible position outside the building, facing downward, preferably over a drain. The pipe must have a continuous fall and be routed to a position so that any discharge of water, possibly boiling or steam, cannot create any danger to persons, damage to property or external electrical components and wiring. Tighten all pipe connection joints.
Gas connection
The supply from the governed meter must be of adequate size to provide a constant inlet working pressure of 20 mbar (8 in wg). To avoid low pressure problems, it is recommended that the supply is taken to the boiler using 22 mm pipe as far as possible. On completion, the gas installation must be tested using the pressure drop method and purged in accordance with the current issue of BS6891.
Thermostatic radiator valves are permitted.
A suitable WRC approved filling loop must be fitted to enable correct filling of the system. In all cases, it is ESSENTIAL that the system be thoroughly flushed prior to installing the new boiler.
Gas Safety (Installation and Use) Regulations.
In your interests and that of gas safety, it is the law that ALL gas appliances are installed and serviced by a competent person in accordance with the above regulations.

BOILER INSTALLATION
To install the boiler, proceed as follows:
· Allowing sufficient clearances for servicing/ repair, place the template on the wall Determine the position of the flue hole and drill hole for flue, preferably using a 120 mm core drill.
· Drill two holes for the hanging bracket, Plug and screw to wall.
· Fasten lower spacing brackets to boiler (see template)
· Remove template.
· Hang the boiler on the hanging bracket.
sheet metal parts to avoid the possibility of personal injury.
Installing the boiler
Prior to installing the boiler, the system must be thoroughly flushed to eliminate any foreign bodies and contaminents such as filings, solder, particles, oil, grease etc.
Note: Solvent products could cause damage to the system.
