If a part is required contact Glow-worm's own service organisation If this appliance is installed in a rented property there is a duty using the telephone number on the inside front cover of this of care imposed on the owner of the property by the current booklet.
Please quote the name of the appliance, this infomation will be on the name badge on the front of the appliance. Please be advised that the 'Benchmark' logbook should be completed by the installation engineer on completion of commissioning and servicing.
Both should be recorded in your benchmark Logbook. Check that all isolating valves on the boiler are open and that water flows from the hot water tap. If you are in any doubt about the boiler being filled with water contact your installer or Glow-worm's own service organisation using the telephone number on the inside front cover of this booklet.
Do not operate the boiler without water. Check that the electrical supply to the boiler is ON and set any remote controls as required.. With the User controls in their "OFF" 0 positions, turn the Mains Reset Switch to the ON 1 position, the running lamp will initially illuminate green then go off, the system pressure will be displayed and should read on the digital display, at least 0. Turn the central heating water temperature control "ON", the lighting sequence will begin, the running lamp will illuminate green to indicate the boiler has lit, the system temperature will now be displayed instead of system pressure.
The temperature of the central heating water can be adjusted by turning the central heating water temperature control to desired setting between 1 'Min' and 'Max'.
Set the control to '0' to switch off heating. If the boiler fails to light, reset the controls, see paragraph below, TO RESET If a fault occurs the running lamp will flash red and a fault code will appear on the digital display. Position 0 - hot water OFF. Turn hot water temperature control between 0 to for hot water 62oC with no pre-heat. Turn hot water temperature control between and for hot water, 40oC - 62oC with pre-heat.
Pre-heat is a function that provides hot water with minimum delay. The ECO setting is recommended and ideally suited to normal family use showers, washing up etc. Positions between ECO and are for occasional use, for water above 55oC approx.
Turn the gas supply OFF at the gas service cock if the boiler is to be out of use for some time. If the digital display shows pressure less than 0. A tap extension is provided to facilitate this. Ensure the tap is closed. However, it is preferable to leave the electrical supply on whenever possible to permit operation of the built-in frost protection see 'Protection Diagram 2 Against Freezing' and daily pump and valve exercise.
To turn off the central heating use the room thermostat or programmer. To turn off the domestic hot water turn the hot water temperature control knob to the minimum setting. For holiday mode turn both of the temperature knobs to the minimum setting. To turn off the boiler for servicing, isolate it from the electrical supply.
To turn it on again follow the instructions given in 'Operation of the Boiler'. The Current I. Wiring Regulations. The flue is supplied seperately. Where no specific instructions are given, reference should be This boiler is for use only on G20 natural gas, but the 30cxi may made to the relevant British Standard Code of Practice. In IE, the installation must be carried out by a competent person Where no British Standards exists, materials and equipment and installed in accordance with the current edition of I.
In GB the installation of the boiler must be carried out by a Manufacturer's instructions must not be taken as overriding competent person as described in the following regulations: statutory requirements. The manufacturer's instructions supplied.
W Max. Domestic hot water flow rate at 35OC rise 24 cxi 9. Diagram 1. It is important that no alteration is made to the boiler, without permission, in writing, from Glow-worm.
Any alteration that is not approved by Glow-worm, could invalidate the warranty and could also infringe the current issue of the Statutory Requirements. In GB this is BS The supply from the governed meter must be of adequate size to provide a steady inlet working pressure of 20mbar 8in wg at the boiler. On completion, test the gas installation for soundness using the pressure drop method and suitable leak detection fluid, purge in accordance with the above standard.
See diagrams 1. The data label is positioned on the inner door, refer to diagram 1. The test data from which it has been calculated has been certified by B. TABLE 2 1. A electromechanical or A digital. This boiler may be installed in any room, although particular attention is drawn to the installation of a boiler in a room containing a bath or shower where reference must be made to 5 5 the relevant requirements.
This boiler is suitable for installation in bathroom zones 2 and 3. In GB this is the current I. In IE reference should be made to the current edition of I. For flue installations where external access is not practicable, consideration should be given for the space required to insert the flue internally, which may necessitate clearance larger than those specified in diagram 2. If in doubt seek advice from the local gas undertaking or Glow-worm. Leave existing air vents.
The instructions for all other flues will be contained in those The flue can be installed from inside the building, when access packs. The diagrams 3. If necessary, it is permitted to increase NOTE. If necessary, it is permitted to increase this dimension to mm max.
If necessary, it is permitted to NOTE. For Ireland the minimum distances for flue terminal positioning must be those detailed in I. The terminal must be exposed to the external air, allowing free passage of air across it at all times. Being a condensing boiler some pluming may occur from the flue outlet. This should be taken into consideration when selecting the position for the terminal. These dimensions comply with the building regulations, but they may need to be increased to avoid wall staining and nuisance from pluming depending on site conditions.
Increased siting flexibility can be achieved by using the Glow- worm Plume Management Kit, A black or A white. NOTE: If necessary it is permitted to increase the terminal protrusion through the outside wall to greater than the minimum dimension of 87mm but no more than mm, see diagram 1.
Care is required to protect the roof if made of plastic sheeting. If it is necessary to alter the flow rate, the system can be fitted The safety valve is an integral part of the boiler and it cannot be with a lockable balancing valve in the main flow or return pipes adjusted. The flow rate through the boiler must not be allowed to fall below that given in table 3. The digital readout on the controls fascia indicates the system pressure when there is no central heating demand.
The boiler is fitted with an adjustable automatic bypass. Ensure that under no circumstances does the flow rate drop below the 4.
The boiler has an integral expansion vessel with a capacity of The installation of the boiler must comply with the requirements 8 litres 1. Table 3.
NOTE: The water pressure at the boiler must be at least 1. The boiler has a built in filling device, see diagram 4. A push- on extension is supplied in the loose items pack to ease access This is equal to 20OC differential at maximum heat input.
This filling device is designed to enable the re-pressurisation of the system in the event of loss of pressure. It is not intended to be used to completely fill the system.
If so used, it may take a long time to fill the system. To fill the system quickly provision should be made to include a proprietry filling loop external to the boiler. Suitable external filling systems are shown diagramatically, see diagram 4. The system should be pressurized to 1 bar, indicated on the digital display with no heating demand.
For optimum performance after installation of a new system, the boiler and its associated central heating system should also be flushed. Flushing should be carried out in accordance with BS using a cleanser such as Sentinel X or X, Fernox restorer or Salamander corrosion guard cleaner.
For long-term corrosion protection, after flushing, an inhibitor suitable for stainless steel exchangers should be used, refer to the current issue of BS and BS on the use of inhibitors in central heating systems. Examples are Sentinel X Fernox protector or Salamander corrosion guard inhibitor. See addendum. General - All domestic hot water circuits, connections, fittings must be in accordance with the relevant standards and water supply regulations.
For IE: The current edition of I. However, in areas where the water is 'hard' i. If the cold water supply pressure exceeds this, Refer to the manufacturer's instructions or consult the local then a pressure-reducing valve must be fitted in the supply to water company for additional advice.
Please check the boiler contents as shown in diagrams 6. NOTE: The fittings pack, pipe pack and document pack are located in the polystyrene packing on the top of the boiler. The flexible condensate outlet pipe is located in the base polystyrene packing under the boiler base. Remove the polystyrene end packing pieces then carefully lay the boiler on its back, remove the two front casing panel securing screws and lift off the panel from two retaining lugs.
Remove the transit packaging behind the front panel and discard. Carefully place front panel and screws to one side. Inclined Extended flue length 6. For standard side flues the horizontal flue centre line on the wall template should be extended to the side wall, and the Standard vertical centre of the flue hole marked at mm from the back flue length wall. For installations with internal access only a mm diameter core drill should be used.
Where this line reaches the side wall, a horizontal line should be marked. The vertical centre line of the flue should then be marked at mm from the back wall, see WALL diagram 6. TEMPLATE To allow for the flue passing through the wall at this angle a mm hole should be drilled irrespective of internal or external installation. Remove the wall template whilst drilling the flue hole. NOTE: Due to the varied site conditions we do not supply fixings and advise that the installer should supply those which are suitable.
Secure the fixing jig to the wall. All water and gas connections are on the fixing jig with before connecting to the boiler. Do not subject the isolation valves to heat. Make sure the drain point is accessible, refer diagram Make connections to fixing jig, gas, water and heating cocks with the tube assemblies supplied in fixing pack as shown in 7.
Before connection check supply of local gas. The appliance will contain a small amount of water, place a Refer also to section 1. Lower the boiler slowly and engage onto the hanging bracket. Make good the final connections. Diagram 7. 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. To ease future servicing it is advisable to use a compression type fitting to extend the safety discharge valve tube.
A flexible condensate outlet pipe Tighten half turn is supplied loose in the base polystyrene packaging and should past finger tight be used to fit on to the drain connection, if required, to discharge SAFETY condensate to a drain. If this is not practicable, discharge can be allowed into the external household drains or a purpose designed soak away, refer to diagram 8.
The condensate is discharged periodically in 'slugs' by siphonic action. It is not necessary to provide air breaks or extra traps in the discharge pipe as there is already a 75mm high trap inside the boiler. Fitting an extra trap may cause the boiler siphon to work incorrectly. Refer to BS or BS for advice on disposal of boiler condensate. Diagram 8. The components supplied in the Standard and Telescopic kit are shown in diagram 9.
