5.1.1 Turning on the Burner
Turn ‘On’ the main electrical supply and turn on the burner demand interlock/switch
. The burner fan
will start and pre-purge. The burner Control will then drive the fan to a pre-set ignition speed. The
ignition spark is generated at this point and the Burner will ignite. The 0-10V temperature control (if
used) will then modulate the Burner to the desired output.
5.1.2 Commissioning operation
We recommend that the operating CO
2
is -0 +0.5 % higher at maximum fan speed than at
minimum.
Check this by driving the burner up and down using the 0
– 10V signal or alternatively, if available,
the dedicated Windows PC software to control the fan speed.
Ensure that all combustion readings are within the required tolerance and if an appropriate gas
meter is available to conduct a heat input measurement whilst operating at maximum rate to ensure
the rate is /-5% of that required for the appliance. If the heat input is outside the re/-
5% tolerance, adjust the fan speed until a satisfactory input is achieved.
Ensure all Combustion, Input and Working Gas Pressures are recorded and return the burner to
normal run condition.
5.1.2.1 Maximum rate CO2
The Maximum CO
2
may be adjusted by use of the Throttle screw on the venturi, turning clockwise
decreases the value and anti-clockwise will increase.
5.1.2.2 Minimum rate CO2
Minimum CO
2
should be adjusted by using the regulator on the gas valve (ideally with the use of a
Micromanometer) to help ensure that it is set accurately as this is a sensitive adjustment.
Remove the T40 Torx cap and turn the screw anti-clockwise to decrease the CO
2
and clockwise to
increase.
