G- High Altitude
NOTE - In Canada, certification for installations at eleva
tions over 4500 feet (1372 m) is the jurisdiction of local au
thorities.
SLP98DFV units require no manifold pressure adjustments
for operation at altitudes up to 10,000 feet (3048m) above
sea level. However, units installed at altitude of 7,501 to
10,000 feet (2287 to 3048m) require a pressure switch
change per table 32. Table 32 also lists conversion kit re
quirements at all altitudes.
The combustion air pressure switch is factory-set and re
quires no adjustment.
