1.If LP gas specify on order. Ratings are the same.

2.AGA Ratings shown are for installations at sea level and elevations up to 2,000 ft. For eleva tions above 2,000 ft. A.G.A. ratings should be reduced at the rate of four percent (4%) for each 1,000 ft. above sea level.

3.Net I=B=R ratings shown are based on normal I=B=R piping and pick-up allowance of 1.15. Consult the manufacturer for installations having unusual piping and pick-up requirements such as intermittent system operation, extensive piping systems, etc.

4.Maximum equivalent length cannot exceed the sum of the length of straight pipe and the equivalent length of any elbow used (90° and 45° elbows equal 5 equivalent feet).

5.The direct vent Minuteman II is designed to vent directly through the wall using Burnham's approved vent system, 3" AL29-4C® stainless steel pipe. Inlet air can be supplied using 4" 26 gauge galvanized or similar.
