This gas inlet supply connection tube kit is designed specifically for Martin MDV direct-vent wall heaters. It replaces the original supply tubes that connect the heater’s gas inlet system. This kit ensures proper alignment, secure gas flow, and safe operation when the original tubing shows signs of wear or misalignment.


Features

  • Precision-cut metallic tubes (two pre-bent supply tubes) and accompanying brass nuts and washers for a secure connection.

  • Manufactured to match the dimensions and orientation of Martin MDV direct-vent wall heater models (such as MDV8, MDV12, MDV20) to ensure proper fit.

  • Constructed of corrosion-resistant metal tubing and brass connection fittings for durability in heating system environments.

  • Clear, easy installation: remove the old tubing assembly, install the new pre-formed supply tubes, secure with included nuts and washers, reconnect gas supply and perform leak check.

  • Compatible with both natural gas and propane versions of Martin MDV direct-vent heaters — verify original configuration before ordering.

 

Maintaining the integrity of the gas inlet supply tubing in your Martin MDV heater is crucial for ensuring safe and reliable heating. When the original tubing becomes bent, corroded, or misaligned due to servicing, age, or vibration, gas flow can be impacted, leading to potential system failures during safety checks. This targeted, cost-effective supply connection kit offers a solution to restore the original factory-style gas inlet assembly without replacing the complete valve or heater. By doing so, you can keep your system operating efficiently and safely.


Installation & Compatibility

Ensure your heater is one of the Martin MDV series direct-vent wall heaters, such as the MDV8, MDV12, or MDV20. Before installation, shut off the gas supply, allow the unit to cool, and remove the heater’s cover. Disconnect the original inlet tubing and fittings, replace them with the new tubing set included in this kit, secure them using the included brass nuts and washers, and then re-connect the gas line. Restore the gas supply and check all connections for leaks using a soapy-water solution, as per the Martin installation instructions. 


Maintenance & Safety

Periodically inspect your heater’s gas inlet tubing and fittings for signs of corrosion, deformation, or leaking. Always ensure the system has been reassembled, with the pilot, burner, and vent pathways cleared of debris, as outlined in the Martin MDV manual.
