Confirm that your supply matches before ordering. Gas-heater BTU input is the fuel input rating; usable heat output also depends on thermal efficiency.

Indoor installations need the correct manufacturer-approved venting arrangement. Check the existing pad and plumbing connection positions when replacing another heater; matching BTU size alone does not guarantee a direct fit.\u003c\/p\u003e\u003ch3\u003eComplete the installation\u003c\/h3\u003e\u003cp\u003eSite-specific gas fittings, electrical work, venting accessories and installation labor are separate.
