For mounting on a different type of boiler, follow the dimensions from the table below. The fire chamber dimensions refer to natural draught boilers (the dimensions can differ with a margin of 10% from the mentioned values). If the L dimension is smaller, the H dimension must be bigger to obtain the necessary power.
If the mounting of the burner will be on a pressurized flame boiler (return flame), please contact the producer.
