If not, proceed tostep 5.5. Clean the main burner.6. Clean the heat exchanger.7. Check the main injector for blockage or damage.8. Check that the flue terminal is unobstructed.The servicing procedures are covered more fully in Frames48 to 53 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' when a frost thermostatis wired directly from the mains may leave a live feed to theboiler.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 goodseal.DO NOT OPERATE THE BOILER IF THE SEALINGPANEL IS NOT FITTED.48 BOILER SEALING PANEL REMOVAL3.

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 1 for CHoperation.3. Fully open a hot water tap. The pump should stop as theboiler switches to HW mode. When the boiler has settleddown check the gas rate, as in step 3, checking themeasured rate against the figures given in Table 1 for HWoperation.4. Check the percentages of CO and CO 2 in the flue gases atthe sampling point provided. Refer to Frame 48.Note.If your meter reads CO in parts per million the figure
