An Ultimate Products inlet cap with bird screen must be fitted at the inlet of the duct. If the duct inlet is located above the roof the underside of the inlet terminal must be at least 2 ft. above roof level and at least 10 inches above any projection on the roof within 7 ft. of the inlet. See Appendix ‘A’ for typical installation drawing and Ultimate Products part numbers. Intake pipe, fittings, and sealant are not furnished by Manufacturer. 2319 Laurelbrook Street, Raleigh, NC 27604 · (800) 542-7221 · FAX (919) 834-4526 · -13 A.10 INSTALLATION CHECK OUT AND START UP Inspect installation and ensure that it has been carried out in accordance with these instructions. Ensure that electrical and gas supplies are isolated. The gas supply should be purged and tested for soundness in accordance with Local and National Safety codes. Open isolating gas valve and test gas connections for soundness using soap solution. Remove burner cover plate by unscrewing 6 screws. Take care not to damage the sealing gasket. Inspect the burner and electrode assemblies ensuring these are securely fixed and all electrical connections securely made. Replace the burner cover plate ensuring that the sealing gasket is correctly positioned and the six screws are fully tightened. The heater will not operate until this plate is refitted. Remove the control housing cover plate by unscrewing the five securing screws. Ensure all internal components are securely fixed and all connections securely made. Open the manual gas valve. Switch on the electrical supply to the heater and observe the correct start up sequence. Ensure that the settings of any time switch and thermostat are such that the heating system will be required to operate. The fan will start to run and “Power On” lamp will illuminate. Safe-start checks are carried out automatically. After the fan has run up to full speed and a satisfactory vacuum condition has been established, ignition sequence will commence. The spark ignition will be energized producing a spark at the ignition electrode. The gas valve will at the same time be energized. If the ignition is successful the flame sensing probe and the ignition spark is switched off. The ‘burner on” lamp indicates that the gas solenoid valve is energized. If ignition is unsuccessful the gas valve will close and the spark ignition de- energized after approximately 6 seconds. For approximately 10 to 20 seconds the fan will purge the system then re-ignition will be attempted. After three (3) attempts at ignition the control unit will “lock-out” - the “power on” lamp will remain illuminated and the fan will continue to run. To reset after “lock-out” switch off the power supply to the system and wait 5 minutes. Then turn the power on. If repeated “locked-out” occurs investigate the cause. 2319 Laurelbrook Street, Raleigh, NC 27604 · (800) 542-7221 · FAX (919) 834-4526 · -14 A.10 INSTALLATION CHECK OUT AND START UP (CONT.) To shut down the heater, switch off the power supply to the system. Automatic control of the heater or a series of heaters may be achieved by incorporating thermostats, time switches, manual over-ride switches etc. in the electrical supply to the heater(s). It is essential to allow a delay of 15 seconds after switching off the system before attempting to restart. If at any time after completion of the start up sequence, loss of flame should occur, the control unit will attempt to reignite. If this is unsuccessful lock out will occur. Set burner gas pressure as follows. Switch off the power supply to the heating system. Connect a ‘U’ tube manometer to the pressure test nipple provided on the combination gas control valve. Remove the cover from the pressure regulator revealing the adjustable screw. Start the heater and using a suitable screwdriver adjust the pressure regulator, turning the screw clockwise to increase the pressure or counter clockwise to decrease the pressure. Set the pressure to appropriate in w.c. from the table of dimensions for correct heater description. Switch off the power supply to the heating system. Disconnect ‘U’ tube manometer and securely replace screw in pressure test nipple. Replace cover screw on pressure regulator. Check the operation of the flame safeguard equipment as follows: With the heater running normally, switch off the gas supply at the shut off valve. The heater should attempt to relight and if the gas valve has been left off “lockout” should occur indicated by the “Power On” light only being illuminated and fan running. Check the operation of the vacuum proving switch as follows. With the heater running normally, pull off the silicone rubber tube connecting the vacuum switch to the combustion chamber. Within one second, the burner should shut off. Then replace the tube securely and observe that the heater proceeds to ignite in the normal way. Replace the controls cover securing the five fixing screws. 2319 Laurelbrook Street, Ra...
