PERFORMANCE
All hoses, hose connections, and hose fittings used for supply-gas plumbing must be designed for use
with the appropriate gas and pressure rating. Incorrect hoses, hose connections, or hose fittings can
crack or leak.
NEVER connect a supply gas to a hose, connection, or fitting that is not designed for that gas type or
pressure.
A replacement hose, connection, or fitting must meet all applicable regulations and codes.
Non-compliant hoses, hose connections, or hose fittings can crack or leak.The wrong fittings can cause
malfunctions with the internal valves because contaminants can enter the valves through damaged or
loose fittings.
CAUTION
INCORRECT SUPPLY-GAS FITTINGS CAN CAUSE VALVES TO MALFUNCTION
Do not change or replace the supply-gas fittings on the gas connect console.
If you alter or replace the fittings, it can cause the internal valves to malfunction if particulates get inside.
