When installing the appliances, the gas supply pressures must be those given above in
order to have maximum burner efficiency.
Pressure mbar = 1 millibar = 1 mbar = 10 mm c.d.a. (water column millimetres)
Power = 1 kW = 860 kcal = 3.6 MJ = 3412 BTU
THESE VALUES ARE
APPROXIMATE - ALWAYS MAKE
SURE THE FLAME IS REGULAR.
