Gas supply

Brava Slim BF boilers leave the factory specifically prearranged
for G20 gas or G30/G31. The G20 models can be converted to
function with G30/G31 using the "specific nozzle kit" (optional)
provided by Sime on request separately from the boiler.
If changing the type of gas to be used, carry out the entire "GAS
phase of the appliance.
CONVERSION"
Boiler connection to the gas mains must be carried out in full
compliance with installation Standards in force.
Perform the following checks before making the connection:
– check that the boiler is compatible with the type of gas supply
– the pipes are clean
– the gas supply pipe is the same dimension as or greater than
that of the boiler fitting (G3/4") and with a load loss less than
Fig. 12
or equal to that contemplated between the gas mains and the
boiler.
