24 Nozzle bores in gas burners
The nozzle bores listed below apply for test flame tubes when using natural gas H to reach required burner
capacity at the burner mixing unit.
NOTICE:
An adjustment of the gas nozzles to specific system requirements (e.g. boiler layout, fuel consistency,
waste gas system, etc.) may be required within the scope of regular commissioning. The operator can on
his own responsibility permanently decrease the overall nozzle area by closing off some of the nozzle bores
with e.g. boiler putty or temperature-resistant screws. An increase of the overall nozzle area of more than
5% must only be done in agreement with a certified technician. In each case, all work may only be carried
out if it is to be permanent and then only by certified technicians.
