SERVICING30 mini HE --- Installation & Servicing33 SERVICING SCHEDULETo ensure the continued safe and efficient operation of theappliance it is recommended that it is checked at regularintervals and serviced as necessary.The frequency of servicing will depend upon the installationcondition and usage but should be carried out at leastannually.It is the law that any service work must be carried out by aregistered CORGI installer.In IE, servicing work must be carried out by a competentperson.1 Turn the heating controls to maximum so that the boilerlights and remains running. Check that no other gasappliances in the house are in use or likely to be used.2 When the boiler has settled down check the gas rate atthe meter (if the meter is of the pointer type you shouldtime only complete revolutions of the pointer). Check thegas rate against the figures given in Table 2 for CHoperation.3 For a combination boiler, fully open a hot water tap. Whenthe boiler has settled down check the gas rate, as in step2, checking the measured rate against the figures given inTable 3 for HW operation.4 Run the boiler and check the percentage of CO and CO2in the flue gasses at the sampling point indicated in thefollowing drawing.Sampling pointsExhaust gasSampling pointsAir intakeNote. If your meter reads CO in parts per million the figuremust be divided by 10,000 to convert it to a percentage.5 If the ratio of CO/CO2 is less than ,004 and the gas ratesmeasured in steps 3 and 4 are close to nominal then nofurther action need be taken. If not, proceed to step 6.6 Clean the main burner.7 Clean the heat exchanger.8 Check the injectors for blockage or damage.9 Check that the flue terminal is unobstructed.The servicing procedures are covered more fully in Frames 34to 36 and MUST be carried out in sequence.WARNING.ALWAYS turn off the gas supply at the gas service cock, andswitch off and disconnect the electricity supply to theappliance before servicing.Switching the boiler on/off switch ‘off’ does not fullyisolate the boiler.ALWAYS test for gas soundness and carry out functionalchecks on reassembly.IMPORTANT. When work is complete the boiler inner frontsealing panel MUST be correctly refitted, making a good seal.DO NOT OPERATE THE BOILER IF THE SEALlNG PANELIS NOT FITTED.Complete the service section in the BenchmarkCommissioning Checklist.SERVICING
