-
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.
