Pro-Tip: When using high-BTU heaters like the Tradesman 400, tank sizing is critical. A standard 100 lb cylinder may freeze up due to the rapid rate of vaporization required by a 400,000 BTU draw. For uninterrupted performance, always use a minimum 500 lb tank or manifold at least two 100 lb cylinders together.
