Description
The NTI Boiler 6000085536 LP Venturi Insert is a gas mixing component used to regulate the air-to-fuel ratio during combustion in compatible boiler equipment. It is installed within the burner and gas valve assembly, where the VM153 EBM 27453.3 configuration controls the flow properties required for propane operation. In HVAC systems the insert supports efficient combustion and stable burner performance by ensuring proper mixing before ignition occur. It plays an essential role in the combustion process and is commonly used during fuel conversion, maintenance, or replacement procedures to maintain heating operation, and consistent thermal output.
