Notes:
- Model number suffix indicates pilot type (E = digital, M = millivolt), fuel type (P = propane, N = natural gas) and tube material (C = copper, X = cupronickel). Example: Model number B-R406A-EN-C indicates a unit with digital (IID) ignition using natural gas with copper tubes.
- Ratings are for natural gas and elevations up to 2,000 feet above sea level. Reduce input 4% for each 1,000 feet above sea level when installed at over 2,000 feet elevation.
