16.
All gas nipples are to be replaced and checked for tightness and checked with
leak detection fluid.
17.
A leak detection test is to be done with leak detection fluid and electronic leak
detector on the gas train while the burner is running, to see if there are any
leaks in the burner gas train and a soundness test is to be done on all gas work.
18. Finally make a full record of combustion data on commissioning sheet
provided; a copy is to be presented to the customer and to BMM Heaters on
completion of work. The commissioning sheet should include the following:-
(a)
Model and serial numbers.
(b)
Heater running temperature and over heat settings.
(c)
Full thermal input.
(d)
Governor pressure settings (pilot for start gas and main for full fire).
(e)
Gas flow rates for full fire.
(f)
Burner damper setting and pressure switch settings.
(g)
Flame signal strength on full fire.
(h)
Exhaust gas O², CO², CO and temperature.
19.
After setting all air pressure switches and valves etc, you must mark the
position or lock off if possible.
Please note BMM Heaters provide a full commissioning service if required. Also if
you require further information call BMM Heaters technical department.
