VII. STEP 7 — ORIFICE CHANGE

This unit is factory assembled for heating operation using natural gas at an elevation from sea level to 2000 ft. This unit uses orifice type LH32RFnnn, where “nnn” indicates the orifice size based on drill size diameter in thousands of an inch.

A. High Elevation (Above 2000 ft)

Use accessory high altitude kit when installing this unit at an elevation of 2000 to 7000 ft. For elevations above 7000 ft, refer to Table 2 to identify the correct orifice size for the elevation. See Table 3 for the number of orifices required for each unit size. Purchase these orifices from your local Bryant dealer. Follow instructions in accessory Installation Instruc- tions to install the correct orifices.

B. Conversion To LP (Liquid Propane) Gas

Use accessory LP gas conversion kit when converting this unit for use with LP fuel usage for elevations up to 7000 ft. For elevations above 7000 ft, refer to Table 4 to identify the correct orifice size for the elevation. See Table 3 for the number of orifices required for each unit size. Purchase these orifices from your local Bryant dealer. Follow instructions in accessory Installation Instructions to install the correct orifices.
