Gas/Air ratio is not 1:1 at high fire
– For example:
at low fire the air control pressure is
2" WC (5 mbar),
the gas outlet pressure is also 2" WC (5 mbar)
at high fire the air pressure is 40" WC (100 mbar),
the gas outlet pressure is lower depending on the
flow rate.
– For the gas/air ratio for high fire use gas limiting orifice
valve for fine adjustments
