Notes:
1. Model number suffix indicates pilot type (E = digital, M = millivolt) and fuel type (P = propane, N = natural gas). Example: Model number
CR-406A-EN indicates a unit with digital (11D) ignition using natural gas.
2. 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,
