Natural gas is a separate part number, so confirm the fuel at the site before ordering. The heater is rated for indoor or outdoor installation, and as supplied it is rated for elevations from sea level to 2,000 feet. Ignition is electronic, so there is no standing pilot to relight after a windy night.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA 400,000 BTU gas heater needs a correctly sized gas line, proper venting if it goes indoors, and the clearances Lochinvar specifies.
