-Water control knob on (Min) position gives
minimum water flow and higher outlet water
temperature. On (Max) position it gives maximum
water flow and lower outlet temperature.
-Gas control knob on (Min) position gives
minimum gas flow and low water outlet
temperature. On (Max) position it gives maximum
gas flow and higher outlet water temperature.
-Summer/winter knob on Summer position to
decrease number of working flame rows to the
half to decrease gas consumption, and on Winter
position it will work all flam rows.
Temporary shutdown
