Operation Instruction Manual

Light Up & Adjustment

• Make sure all fuel shut-off valves are closed. Open furnace door and dampers.
• Start blower and check direction of rotation. Care should be taken that discharge or the suction on the blower is closed during start-up.
• Start outflow heater, oil pumps and line heaters and circulate oil through the ring main. temperature should be in the range of 100 to 110Deg.C. for 1500 secs. Redwood No.1 oil and oil pressure at the Ratiotrol 25 to 30 psi.
• Open burner air valves and zone control valves wide for purging the furnace.
• When the Furnace is purged of all combustible gases, turndown the air control butterfly valve to 1/4 or less open (Low Fire Position), leaving individual main and atomizing air butterfly valves fully open.
• Insert a torch through the pilot hole opening in the mounting plate and gradually open sensitrol oil valve till burner lights up.
• After burner is lit, gradually open zone air butterfly control valve till the burner has reached high fire condition. Set air/fuel ratio by adjusting the sensitrol oil valve. This is the ‘HIGH FIRE’ setting. Gradually the sensitrol valve if required. Lock the sensitrol oil valve by tightening grub screw provided on the valve bonnet. Also move indicator to sensitrol handle position. This act as high fire position indictor close the zone air butterfly valve to 1/4 or less open, loosen the spring catridge lock-nut and adjust spring cartridge of the Ratiotrol to set air fuel ratio. This is “LOW FIRE” setting. Gradually increase to high fire and adjust. The air-fuel ratio of the burner is now set.

Note: If burner does not light up within 15 to 20 seconds, close sensitrol oil valve and Purge the furnace before trying to light up again.
