HIGH ALTITUDE OPERATION
This Unit heater is factory configured for altitudes from 0 – 2,000 ft above sea level. Above 2000 ft. (610m), manifold pressure must be adjusted
according to the following tables:

In case the manifold pressure is changed for this reason, the altitude label in the conversion kit must be completed and affixed to the unit:
This appliance was converted on ______ (day-month-year)
for operation at ____ ft.(___m) altitude by ____________
(name and address of the organization making this conver-
sion) which accepts the responsiblity that this conversion
has been properly made.
