NOTE

SAFE LIGHTING AND OTHER PERFORMANCE CRITERIA WERE MET WITH THE GAS MANIFOLD AND CONTROL ASSEMBLY PROVIDED ON THE BOILER WHEN THE BOILER UNDERWENT THE TESTS SPECIFIED IN Z21.13.

Use the following procedure for initial start-up of the boiler:

1)Make sure that the boiler and system are filled with water.

2)Check all new gas piping for leaks and purge piping sections that are filled with air. See Part 4 of the National Fuel Gas Code for additional information on testing and purging gas lines.

WARNING

•NEVER USE A FLAME TO CHECK FOR GAS LEAKS.

•MAKE SURE THAT THE AREA AROUND THE BOILER IS CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND LIQUIDS.

3)Verify that vent system is complete and free of obstructions before attempting to fire boiler.

4)Inspect all wiring for loose or uninsulated connections.

5)Make sure the main burners are seated properly in the rear of burner tray and on orifices.

6)Adjust thermostat to the highest setting.

7)Start the boiler using the lighting instructions for boilers with standing pilot (page 24) or operating instructions for boilers with intermittent ignition (page 25).

8)Upon initial start-up, the gas train will be filled with air. Even if the gas line has been completely purged of air, it may take several tries for ignition before a flame is established. Once a flame has been established for the first time, subsequent calls for burner operation should result in a flame on the first try.

9)Observe pilot burner flame:

• See Figure 20 for standing pilot. Pilot burner should produce single steady medium blue flame covering around 3/8” to ½” of thermocouple tip.

•See Figure 21 for intermittent ignition. Pilot burner produces three flames. The center one should be a steady medium blue flame covering around 3/8” to ½” of spark electrode/flame rod.

10)Make sure vent damper is in open position when main burners are firing.

11)Inspect the main burner flames visible through the observation port in burner access panel. The flame should be stable and mostly blue (see Figure 22 or 23). No yellow tipping should be present; however, intermittent flecks of yellow and orange in the flame are normal.

12)Check entire gas train for leaks using soap and water or other approved leak detection method while boiler is firing. Fix any leaks found immediately.
