The whole of the gas installation, including the meter, should be inspected, tested for soundness and purged in accordance with the current issue of BS6891 and in IE the current edition of I.S.813 "Domestic Gas Installations". SCREWS (4) 5.6 Control Box Access Slacken the control box securing screw, see diagram 5.10. Swing the box out on its hinge. 5.
5 Boiler Installation 5.8 Pump Connection 1. Test insulation resistance to earth. The pump must be connected to the external controls. 2. Test earth continuity and short circuit of all cables. 3. Test the polarity of the mains. 5.9 Testing The installer is requested to advise and give guidance to the user of the controls scheme used with the boiler. Checks to ensure electrical safety must be carried out by a competent person. Fit the casing.
6 Commissioning IMPORTANT NOTE: The warning notice attached to the front of the boiler casing must only be removed by the user. 7318 FASCIA Please ensure the “Benchmark” logbook is completed and left with the user. 6.1 All Systems Commissioning should be carried out by a competent person in accordance with the current issue of BS6798. Do not operate the boiler wthout water. UNDER ALL CIRCUMSTANCES the case must be correctly fitted and sealed, unless fault finding.
6 Commissioning 6.4 Testing - Electrical Table 2 Turn the boiler temperature control knob fully clockwise to the maximum setting, which is approx. 82OC (180OF). 30FF The lighting sequence is automatic as follows: APPROX. GAS RATE The fan will operate for 10 seconds prior to the start of the ignition sparks, the gas valve solenoids will open and the burner will light. This is shown by the "Burner Lit" LED on the control panel lighting up. MAX. m3/h ft3/h 1.00 35.
7 Instructions to the User Instruct and demonstrate the safe and efficient operation of the boiler, heating system and domestic hot water system. Advise the user, that 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 particular installation and usage, but in general once a year should be enough.
REMEMBER: When replacing a part on this appliance, use only spare parts that you can be assured conform to the safety and performance specification that we require. Do not use reconditioned or copy parts that have not been clearly authorised by Glow-worm. SAMPLING POINT 7231 8 Servicing Products of Combustion Check NOTE: To obtain a products of combustion reading, remove the cap from the sampling point, located on top of the inner casing, see diagram 8.1. Connect the analyser tube onto the nipple.
8 Servicing 6801 8.4 Injector With the burner removed the injector can be inspected and cleaned as necessary, see diagram 8.5. For cleaning do not use a wire or sharp instrument on the hole. If removed, use a little suitable sealant on the external thread when refitting to make sure a gas tight seal is made. 8.5 Operational Checks After completing a service and before fitting the case, check condition of the case seal and renew if necessary.
10270 9 Fault Finding Before carrying out fault finding, ensure that gas, electricity and water are available to the boiler. Ensure that any external controls are calling for heat and circuit water is cold. If Reset LED is lit - check water system for overheating, reset by turning temperature control knob off and on. If the LED coding is showing an ignition failure, reset the boiler by turning the control knob off and on. Do not operate the boiler without combustion chamber front fitted.
