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 vlave and confirm greater than 3.5 inch w.c. gas pressure is measured
4. Check flue and air vent connections
5. Ensure boiler is fully filled with water and all air is purged, the boiler pressure shall be at least 20 psig.
6. Check pumps for correct flow capacity and flow 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 flow 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

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/flame failure
9. Reset control
10. Open firing valve
11. Check ignition quality, and flame stability and flame signal, the minimum flame signal shall be at least 5µA/V,
nominally the flame signal shall range from 8 to 32µA/V
