4. Ensure that all wiring connections are correct and that all terminal screws are tight.
5. A barometric type draught stabiliser, if fitted in the flue, should be set for a draught of
- 0.025 mbar to - 0.05 mbar of water column pressure with the burner off.
6. Open all the valves in the feedwater line.
Close the isolating valve on the discharge side of the feedwater pump. Remove the priming
plug from the pump head and slowly fill the pump with water. Replace the priming plug and
tighten securely.
7. Check the correct rotation of the pump on the motor fan cover.
Start the pump and check the direction of rotation.
Vent the pump by means of the vent valve in the pump head. At the same time, open the
discharge isolating valve a little. Continue to vent the pump. At the same time, open the
discharge isolating valve a little more.
Close the vent valve when a steady stream of water runs out of it.
Completely open the discharge isolating valve.
The bypass valve located in the drain plug may be opened during the filling procedure, close
the bypass when the operation is stable.
DO NOT ALLOW THE PUMP TO RUN DRY.
8. Open all the valves in the water feed line.
Switch on the feedwater pump motor and fill 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.
WARNING
Gas purging by qualified persons only.
!
9. After purging the gas lines of air, start the burner.
For models 40J - 60J with an external pilot gas line, see
Section 2.13.2 - Setting the burner
controls
.
Note:
Prove the pilot flame by placing the PILOT HOLD / NORMAL switch into the Pilot Hold position, this will
hold the gas valve in the pilot gas position until the pilot flame has been verified.
10. Check the burner control is in the run position.
11. Adjust the gas and main air control gate located on the burner scroll, to obtain a clean
combustion. Measure the levels of CO
2
CO and O
2
in the exhaust gas and record the results.
See typical combustion values given in
Appendix A - TI 117
.
12. Observe the flame through the eye glass and adjust the secondary air control located on the
top of the boiler, so that the flame can be seen passing down the blast tube.
13. Check the operation of the low water safety controls.
14. Adjust the steam pressure control to suit the boiler application. It should be borne in mind that
boilers are designed to operate most efficiently 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 fitting of a pressure reducing set.
