Ratings shown are for unit installations at elevations between 0 and 2,000 ft. (610m).

For unit installations in U.S.A. above 2,000 ft. (610m), the unit input must be derated 4% for

each

1,000

ft.

(305m)

above

sea

level; refer to local codes, or in absence of local codes, refer to the latest edition

of the National Fuel Gas Code, ANSI Standard Z223.1 (N.F.P.A. No. 54).

For installations in Canada, any reference to deration in excess of 2,000 ft. (610m) are to be

ignored. At altitudes of 2,000 to 4,500 ft. (610 to 1372m), the unit must be derated to 90% of the

normal altitude rating, and be so marked in accordance with the CSA certiÞ cation.

These amps are based on standing pilot units.

R = Round; OV = Oval; H = Horizontal; SP = Shaded Pole; PSC = Permanent Split Capacitor.
