Classic FF - Propane Installation & Servicing 25INSTALLATIONCL1869B C E FA D J44 COMMISSIONING AND TESTINGA. ELECTRICAL INSTALLATION1. Checks to ensure electrical safety should be carriedout by a competent person.2. ALWAYS carry out preliminary electrical system checks,i.e. earth continuity, polarity, resistance to earth andshort circuit using a suitable test meter.WARNING. Whilst effecting the required gas soundness test and purging air from the gas installation open allwindows and doors, extinguish naked lights and DO NOT SMOKE.45 INITIAL LIGHTINGB. GAS INSTALLATION1. The whole of the gas installation, including the meter,MUST be inspected and tested for soundness, and purgedin accordance with the recommendations of BS. 6891.In IE refer to I.S.813:2002.2. Purging air from the gas installation may be expedited byloosening the union on the gas service cock on the boilerand purging until gas is detected.3. Retighten the union and check for gas soundness.TO LIGHT THE BOILER1. Check that all the drain cocks are closed, and any valvesin the flow and return are open.2. Check that the gas service cock (B) is OPEN and theboiler mains On/Off switch is OFF.3. Fitting the Boiler CasingThe boiler casing must be refitted with the controlssupport casing attached for alignment purposes. Liftthe boiler casing up to the boiler assembly, with thecasing top angled forward. Hook the top edge of theboiler casing into the channel on the top of the boilerassembly. Swing the bottom of the casing down andsecure with the 2 captive screws.The casing must seat correctly and compress thesealing strip to make an airtight joint.Visually check the side seals but, if side clearances arelimited, then check that the top and bottom edges of thecasing are correctly located.Note. If the Sealed System Unit is fitted remove the unitcasing in order to inspect the top casing seal.To gain access to the gas valve:a. Remove the controls support casing. Release thecontrols support front fixing screws 3 turns only.Remove the pod by pulling it forward to disengagefrom the keyhole slots.b. Remove the control box securing screws and swingit down into the servicing position. See diagram B,Frame 46.4. Slacken the screw in the burner pressure test point (F) andconnect a gas pressure gauge via a flexible tube.5. Swing the control box back into its working position.6. Press the overheat thermostat reset button (J).7. Switch the electricity supply ON and check that all externalcontrols are calling for heat.8. Set the boiler thermostat knob (D) to position 6 and theboiler Mains On/Off switch to ON. The fan will start. Afterthe fan has run for a few seconds the pilot solenoid valveshould open and the intermittent spark commence,continuing until the pilot is established. The main burnerwill then cross-light smoothly. If this sequence does notoccur, refer to the Fault Finding section.9. Test for gas soundness around ALL boiler gascomponents using leak detection fluid.10. Operate the for 10 minutes to stabilise the burnertemperature.The boiler is preset at the factory to its nominal rating.Check the burner pressure against the values quoted inTable 2 (page 2). The inlet pressure measured at the gascontrol valve must be 37mb.11. Set the main On/Off switch to OFF.12. Switch the electricity supply OFF.13. Swing the control box down into the servicing position.14. Remove the pressure gauge and tube. Retighten thesealing screw in the pressure test point. Ensure a gastight seal is made.LEGENDA Sightglass.B Gas service cock.C Inlet pressure test point.D Thermostat knobE Main burner pressure adjuster.F Burner pressure test point.H Boiler mains on/off switch.J Overheat thermostat resetbutton.The Benchmark Log Book or equivalent self certification should be completed and signed to demonstrate compliance withBuilding Regulations.INSTALLATION
