Specifically designed for:
- Precise Natural Gas Flow Control: The #18 orifice size is chosen to regulate the precise amount of natural gas delivered to the burner. This item helps with maintaining the correct air-to-fuel ratio necessary for efficient and safe combustion.
- Optimal HVAC System Performance: By ensuring the correct gas flow, the orifice aides in maintaining the desired temperature output and overall efficiency of the heating system.
- Altitude Adjustment (in some cases): This particular orifice is also identified as being designed for use with natural gas furnaces installed at higher elevations (specifically, between 2000-2999 feet). It can replace a standard orifice to optimize performance at these altitude
