Checking piping connections Check
Check that the water piping system is fully flushed and charged, and that all air has been
discharged through loosened bleed caps.
Note it is possible to switch all pumps on/off from the touchscreen without a call for heat.
This simplifies system filling and air bleeding (go to Installer Setup > System Settings > Site
Settings > change Manual Pump Purge to "ON". Loads must be assigned. When complete,
return to "OFF", or this will automatically occur with a call for heat). Use a minimum water
pressure of 12 psig. And confirm that the pressure relief valve is installed and safely drained.
Check to see that adequate gas pressure is present at the inlet gas supply test port.
Open the test port by turning its center-screw one full turn counterclockwise, using a small
(1/8" or 3 mm) flat screwdriver. Connect a manometer and open the gas control valve.
Requirements are minimum 4" w.c and maximum 14" w.c.
Check that there are no gas leaks.
All connections are pressure tested and leak free.
All piping flushed to ensure all air is removed.
Check valve is installed and the external pump is flowing in the correct direction.
Checking vent connections Check
All connections are pressure tested and leak free.
All vent pipe is sized correctly and joints are sealed.
Powering on the boiler Check
Perform a final check of electrical wiring, and provide power to the boiler to initialize
operation.
Warning
Fill the condensate trap with water before you first fire the boiler to prevent exhaust fumes
from entering the room. Never operate the boiler unless the trap is filled with water.
Failure to comply will result in severe personal injury or death.
