Description
The Heatstar 21667-15 15′ Hose & Regulator Assembly DXH65FAV QBT2 supplies and regulates fuel gas for compatible heating equipment. Its 15-foot hose provides extended routing between the fuel source and heater connection, while the regulator controls gas delivery to the required operating level. The assembly connects between the fuel supply and heater with the hose and regulator fittings properly secured. HVAC systems use this arrangement where a compatible gas-fired heater requires a controlled fuel connection for operation. The regulated flow supports steady burner fuel delivery, while the flexible hose allows practical positioning of the heater relative to the fuel source. This assembly supports consistent combustion and controlled heating during normal equipment operation.
