Notes for the above tables:
Use caution in shaded areas.
Values above are calculated at sea level.
Temperature rise = Sea level temperature rise / (1−Elevation (ft.) x 0.0000334)
Gas inlet pressure required for natural gas minimum 5” w.c., maximum 13.5” w.c.; for propane minimum 11” w.c., maximum 13.5” w.c.
High altitude kit required for elevations over 2,000 feet.
