Calculation of fuel constants are detailed in the APPENDIX. Fuel
constants will have to be calculated before a user fuel can be entered.
To enter the user fuel select
‘User Fuel’ and Press
Use and to select
the correct value.
Use to move to the next parameter, repeat above until all
parameters are correct. Press to return to SELECT menu.
O2 Ref : Toxic gas measurements can be referenced to defined
oxygen levels. Reference values can be set from 1-20%, to
AUTO or more normally to the default value - OFF. Setting to
AUTO uses the figure in the FUEL constants data.
Once AUTO is set it remains active until O2 Ref is set to OFF
or a user value. This means that if the fuel type is changed
the O2 Ref will always be set by the value stored in FUEL
Type.
Oxygen referencing is required by some regulations such as
TA-LUFT. If a reference value is selected then toxic gas
measurements will be displayed with the symbol (n) attached
to the reading. i.e. CO(n)
What does Oxygen reference mean ?
If 3 % O
2
reference is selected and 5 % O
2
is measured in the
flue then toxic gas values will be recalculated as if 3 % were
measured. The equation for referencing is detailed in the
Appendix.
Oxygen referencing prevents false readings being submitted,
e.g. allowing more air into the boiler will increase the oxygen
