START-UP PROCEDURES
7. START-UP PROCEDURES
A.COMPLETING THE INSTALLATION
1.Confirm that all water, gas and electricity are turned off.
2.Inspect the boiler combustion chamber for foreign objects and remove if present.
3.Check physical condition of burners and pilot. Make certain that there are no unusual bends or perforations in the burners or pilot. Replace components if necessary.
4.Verify that water piping, venting, gas piping and electrical wiring and components are installed properly. Refer back to previous sections of these instructions as well as equipment manufacturer’s instructions as necessary.
5.Fill the boiler and system with water, making certain to vent all air from all points in the system. To check water level in the system, open and close each vent in the system. Water should exit from each vent when it is opened.
6.The pressure reducing valve on the fill line will typically allow the system to be filled and pressurized to 12 psi. (83 kPa). Consult the valve and expansion tank manufacturer for more specific information.
7.Check joints and fittings throughout the system for leaks. If leaks are found, drain the system and repair as required.
8.Connect a manometer to the gas valve inlet pressure tap. See Figure 7.2.
9.Confirm that the gas supply pressure to the boiler is above the minimum and below the maximum values for the gas being used. See the end of Section 5 for these values. If a supply pressure check is required, isolate the boiler and gas valve before performing the pressure check. If the supply pressure is too high or too low, contact the gas supplier.
10.Turn on electricity and gas to boiler.
11.Light the boiler by following the Lighting/Operating Instructions label mounted to the jacket panel. The initial ignition may require several tries as the piping is purged of air.
12.Use the sequence descriptions in Figures 6.2 and 6.3 in Section 6 (Electrical) to follow
13.The gas manifold and control assembly are made of
