SECTION 3 - SERVICING COMPONENTS

NOTE: Installations at higher altitudes have a lower ambient air pressure that disrupts the air-fuel mixture. To correct this

problem, smaller gas orifices are required. A general rule is a 4% reduction for each 1000 ft. (305m) above sea level. Refer

to the chart in the Appendices section (page 135) for a listing of orifice sizes showing this reduction.
