Classic LXRS, RS - Propane Installation 15INSTALLATION24 COMMISSIONING AND TESTINGA. ELECTRICAL INSTALLATION1. Checks to ensure electrical safety should be carried out bya competent person.2. ALWAYS carry out preliminary electrical system checks, i.e.earth continuity, polarity, resistance to earth and shortcircuit using a suitable test meter.3. Refit the control box.INSTALLATIONWARNING. Whilst effecting the required gas soundness test and purging air from the gas installation,open all windows and doors, extinguish naked lights and DO NOT SMOKE.repeatedly until the pilot is seen to light through thesightglass (B).6. Hold the gas control knob depressed for 15 seconds afterthe pilot burner has ignited, then release.7. If the pilot burner fails to remain alight at this stage, repeatthe procedure detailed above but wait longer than 15seconds before releasing the gas control knob.8. Check the appearance of the pilot flame to ensure that itenvelopes the tip of the thermocouple and isapproximately 25mm (1") long.The pilot flame is factory set and no adjustment is possible.If the pilot flame is incorrect refer to Frame 35 .9. Check that the electricity supply and all external controlsare ON.10. Set the boiler thermostat control knob to position 6 andcheck that the burner cross-lights smoothly from the pilotflame.11. Test for gas soundness around the boiler gas componentjoints, using leak detection fluid.12. Operate the boiler for 10 minutes to stabilise the burnertemperature.13. The boiler is pre-set at the factory to its nominal rating.Check the burner pressure against the values quoted inTable 2, page 3. The inlet pressure measured at the gascontrol valve must be 37mb.14. Set the boiler thermostat control knob to OFF. Remove thepressure gauge tube and tighten the sealing screw in thepressure test point. Relight and check for gas soundnessat the pressure test point.15. Deluxe Model (LX) - Refit the controls casing bottom paneland screws.Standard Model - Refit the controls pod and tighten thefront fixing screws.16. Deluxe Model (LX) - Lower the glass fascia to its closedposition.Standard Model - Close the pod door.1. Check that all drain cocks are CLOSED and any valvesin the flow and return lines are OPEN.2.

Loosen the screw in the burner pressure test point (E)and connect a gas pressure gauge via a flexible tube.4. Turn the gas control knob clockwise until resistance is feltand then release.WAIT FOR 3 MINUTES.5. Push in and retain fully depressed the gas control knob(A).

GAS INSTALLATION1. The whole of the gas installation MUST be inspectedand tested for soundness, and purged in accordancewith the recommendations of BS. 6891.2. Purging air from the gas installation may be expedited byloosening the union on the gas service cock on theboiler and purging until gas is detected.3. Retighten the union and check for gas soundness.
