COMMISSIONING
5.3 - Commissioning the oil burner
- While the oil burner has been adjusted at the fac-
tory, it is recommended that the operating cha-
racteristics of the burner be determined at start-
up and readjusted if necessary. Run the unit long
enough at the burner maximum firing rate to
make sure the burner has reached a stable maxi-
mum operating temperature. THEN, check the
burner as follows:
- When commissioning the oil burner for the first
time:
• check that the smoke spot number does not
exceed 0.5 (BACHARACH control),
• check the CO2 rate - 11.5 to 12.5 %, CO < 100
ppm (watch out for secondary air inlets),
• check the temperature of the combustion pro-
ducts (under 230°F - 110 °C).
Remark:
- The air and oil inlet settings must be checked sys-
tematically on commissioning and after all main-
tenance operations on the burner by testing the
opaqueness of the flue gasses and of the % CO2
- See the burner technical instructions.
Ensure that the maximum heat flow is
respected.
Combustion inspection must be carried
out when the boiler is heated up. The
temperature of the air allowed to pass
to the burner increases notably when
the boiler is installed with a concentric
flue.
Combustion control is carried out on
the boiler through the opening (15) pro-
vided for this purpose after the cap is
removed. This opening must be closed
again after checking.
6 - CHECKING THE SAFETY DEVICES
At the time of commissioning, check the safety and
control devices.
- Thermostats :
• Check that the thermostat bulbs are correctly
positioned in their housing. Burner shut-off
through a temperature increase,
- Flame monitoring :
• Burner shut-down through the deactivation of
the flame monitoring device or the interruption
of the fuel inlet,
- 30 Psi safety valve (heating circuit),
