9. COMMISSIONING

Warning

If you do not follow the commissioning instructions exactly, a re or explosion may result causing property damage,

personal injury or loss of life.

9.1 Pre operational checks

1. Check power supply ensure fused and service disconnect provided as required by local code or authorities having

jurisdiction.

2. Check gas connection to boiler and check for gas leaks, purge gas according to local codes or authorities having

jurisdiction.

3. Check gas supply pressure on inlet of gas valve test point ID # 3, a test port with plug has been provided, loosen

set screw and connect a manometer and conrm greater than 3.5 inch w.c. gas pressure is measured.

4. Check ue and air vent connections

5. Ensure boiler is fully lled with water and all air is purged, the boiler pressure shall be at least 11 psig.

6. Check pumps for correct ow capacity and ow direction

7. Ensure relief valve is properly connected, sized and piped to nearby drain

8. Fill condensate P trap assembly, if Ph neutralizer used, ensure no obstructed ow through neutralizer to drain.

Ensure all piping of condensate is gravity feed to drain.

9. Check water connections to the system are correct and all isolation valves are open

10. Check to ensure boiler drain connection is provided.

11. Ensure boiler has been installed and properly mounted to the boiler pad if provided, anchoring of boiler per local

codes and seismic

12. Ensure required service area has been provided around boiler as recommended.

9.2 Safety checks and lighting instructions

1. Turn ON main power supply

2. Turn OFF Firing gas valve

3. Open the main gas valve.

4. Check the gas connections for gas leaks.

5. Ensure boiler is open to system, pumps ON and adequate ow is provided through boiler.

6. Adjust the boiler controls to heat demand.

7. The boiler should start and check start interlocks and start purge to pre-ventilation purge position

8. The boiler will automatically go into the ignition phase and then shutdown on ignition/ame failure

9. Reset control

10. Open ring valve

11. Check ignition quality, and ame stability and ame signal, the minimum ame signal shall be at least 5µA/V,

nominally the ame signal shall range from 8 to 32µA/V
