Nominal boiler rating at normal operating temperature using Kerosene (Class C2)
Smoke readings may be inaccurate until the smoke from
the burning organic binder in the access door insulation
has ceased.
If the flue gas temperature is too high and the baffles are
correctly fitted, then reduce the oil pump pressure [3]
fig. 75, 5-10 p.s.i. to compensate for nozzle variations.
If the pump pressure has been changed, the CO2 levels
must be rechecked and air shutter adjusted if necessary.
