7. CONTROL & PRESSURE CHECKS7.1 Check control settings.7.1.1 If closed , open the isolating valve at the inlet ‘T’ connector.7.1.2 To check the control positions temporarily place the fascia loosely over theengine. Fit the control knob over the gas tap spindle.7.1.3 Manual ignition: Depress the control knob and turn anticlockwise partiallytowards the 1/IGN position until some resistance is felt. Keep depressed at thisposition for a few seconds to purge air from the system then, while keeping itdepressed, turn fully to the 1/IGN position. A spark should be generated at the pilotwhile turning. The spark should ignite the pilot. If it does not, keeping the knobdepressed, continue to turn the knob anticlockwise. A second spark should begenerated at the pilot while turning. This spark should ignite the pilot.7.1.3 Electronic ignition: Depress the control knob slightly and turnanticlockwise towards the 1/IGN position. Do not apply too much pressure as this willcause resistance to be felt. Depress the control knob. Sparks should be generated atthe pilot. The sparks should ignite the pilot. If the pilot does not light, turn the controlknob back to the‘OFF’ position and try again.7.1.4 When pilot ignition has been achieved, keep the control knob depressed forapproximately ten seconds to allow the thermocouple probe to warm up and thenrelease it. If the pilot does not remain alight, ensure that the air has been purged, thatthe pilot orifice is clear and that the thermocouple connections are sound. Replacethe pilot unit if necessary (See servicing section of this manual).7.1.5 Check all the control settings.

Set at position 5 and leave for one minute.7.2.2 Turn back to “OFF” to extinguish the pilot. Note the time when the pilot goesout. Listen for a snap sound at the gas tap. Note the time when the sound isheard. An electromagnetic valve shutting off the gas supply through the tap causesthis sound. The valve is located in the body of the tap. The valve should operatewithin 60 seconds of the pilot going out. If the valve does not operate within thisPage 22© Baxi Heating U.K. Limited 2008.Control KnobPosition Radiants Condition2 Centre radiants on low. Outer radiants off.3 Centre radiants fully on.
