For L.P. Gas, correct the total Btu/hr by multiplying it by 0.6. The answer is the equivalent Btu on the above chart.
Table 6
High Altitude Burner Orifice Sizing
For proper operation at altitudes above 2000 feet [610 m], the gas
burner orifice size must be reduced to ensure complete combus-
tion. Refer to
Table 7
.
For CE models, consult local gas supplier.
