9. Open all the valves in the water feed line.
Switchonthefeedwaterpumpmotorandlltheboiler(seeSection 4.5 - Filling the boiler).
The operation of the pump controls should be checked by using the boiler blowdown valve
(located at the rear of the boiler). When the water level gauge (sight glass) is reading two
thirds full, the pump will stop.
10. Open the boiler blowdown valve and slowly drain the boiler. When the water level falls below
the PUMP ON probe, the pump should start. If the pump does not start, check the probe
connections.
11. Close the boiler blowdown valve.
12. After purging the gas lines of air, start the burner as detailed in Section 3.6 - Boiler Start-Up.
For models with an external pilot gas line, see Section 3.2 - Setting the burner controls.
13. Aftertheburnerhasbeenringforapproximatelyveminutes,adjustthegasandmainair
control gate located on the burner scroll, to obtain a clean combustion. Measure the levels of

in the exhaust gas and record the results.
See typical combustion values given in Appendix A - TI 128.
14. Observetheamethroughtheobservationglassandadjusttheprimary/secondaryaircontrol

15. Check the operation of the low water safety controls (see Section 5.4.2 - Low Water Level
Check).
16. Adjust the steam pressure control to suit the boiler application (see Section 4.2.3 - Steam
Pressure Controls). It should be borne in mind that boilers are designed to operate most
efcientlyattheirmaximumoperatingpressure.Whenboilersaretobeoperatedbelowa
pressureof80psi(5.5bar)considerationshouldbegiventothettingofapressurereducing
