Ensure that the heater and all controls are suitable for the gas, pressure and electrical supply to which they are to be connected. 11.1.1 Louvres Where fitted, the air delivery louvres need to be set during commissioning to give the required air distribution. 11.1.2 Electrical Checks 1. Check that all site wiring is connected in accordance with the appropriate wiring diagrams on Page 17, Section 10.3 through Page 20, Section 10.6. 2. Check the correct fuse size is fitted; See Page 16, Section 10.1. 11.2 Gas Supply All aspects of the gas installation including the gas meter must be inspected, tested for soundness and purged in accordance with local and national codes. 11.3 Mechanical Checks 1. Check that the fan is free to run and that the fan rotates in the correct direction. To reverse rotation, transpose two of the incoming phase connections. 2. Check that the flue and air intake are installed in accordance with these instructions and local regulations. 3. Check that the settings of the Combination Fan/ Limit thermostat are correct - See Page 7, Section 4.3 and Page 8, Figure 4.4. NOTE: The second limit thermostat is preset and sealed at the factory and is not adjustable. 11.4 Begin Commissioning 11.4.1 Before Operating the Heater To ensure that all the controls are in safe working order, operate the heater for the first time with the isolating gas valve turned off. 1. Turn off the isolating gas valve 2. Using the installed external control, turn on the burner. The automatic sequence will now begin as described on Page 22, Figure 12. There will be no ignition of the burner and lockout will occur, proving the controls are operating correctly. . #+, . & " ! . !! . . ! ".

The Honeywell automatic gas valves are fitted with the Honeywell Modureg modulating regulator. See Page 22, Figure 13. The Modureg device provides the adjustments for maximum and minimum firing and is set using the two adjustments. See Page 22, Figure 13. The external control will operate the burner between these two limits depending on heat demand. The minimum set point must not be set lower than the minimum burner pressure stated on Page 6, Section 4...
