Specifications are subject to change without notice.

S The rated gas inputs shown in Table 6 are for altitudes from sea

level to 2000 ft (610 m) above sea level. These inputs are based

on natural gas with a h eating value of 1025 Btu/ft

at 0.60

specific gravity, or propane gas with a heating value of 2500

Btu/ft

at 1.5 specific gravity .

IN THE U.S.A.:

The input rating for altitudes above 2,000 ft (610 m) must be

reduced by 4% for each 1,000 ft (305 m) above see level.

For installations below 2,000 ft (610 m), refer to the unit rating

plate.

For installations above 2,000 ft (610 m). multiply the input on the

rating plate by the derate multiplier in Table 3 for correct input rate.

*In Can ada see Canadian Altitu de Adjustment.

{Derate multiplier factors are based on midpoint altitude for altitude range.

IN CANADA:

The input rating for altitudes from 2,000 (610 m) to 4,500 ft (1372

m) above sea level must be derated 10% by an authorized Gas

Conversion Station or Dealer.

When the gas supply being used has a different heating value or

specific gravity, refer to national and local codes, or contact your

distributor to determine the required orifice size.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in reduced unit

and/or component life.

Do Not redrill an orifice. Improper drilling (burrs,

out-- of--round holes, etc.) can cause excessive burner noise

and misdirection of burner flame. If orifice hole appears

damaged or it is suspected to have been redrilled, check

orifice hole with a numbered drill bit of correct size.

*In the U.S.A., the input rating f or altitudes above 2000 ft (610m) must be reduced by 4% f or each 1000 ft (305 m) above sea l evel.

In Ca nada, the input rating for altitudes from 2001 to 4500 ft ( 611 to 1372 m) above sea level must be derated by 10% by an authorized gas conversion stationor

dealer.

For Canadian Installations from 2000 to 4500 ft (610---1372 m), use U.S.A. column 2001 to 3000 ft ( 611 to 914 m).
