FILTER RACK—Downflow top return mount. Requires (2) 14 x 20 Filters.
NOTE: Filter racks are shipped without filters.
FOR HIGH ALTITUDES:
HIGH ALTITUDE OPTION CODE: U.S. & Canada –
None required for high altitudes.
HIGH ALTITUDE CONVERSION KITS: U.S. & Canada –
None required for high altitudes.
80+ HIGH ALTITUDE INSTRUCTIONS
Caution: Always follow National Fuel Gas Code (NFGC) guidelines when
converting for high altitudes.
High altitude option codes are not required for these models. However, the
burner orifice size needs to be recalculated and verified at elevations above
2000 ft. See Installation Instructions for more information.
NOTE: For Canadian installations only, an optional derate (manifold gas
pressure reduction) method may be used to adjust the furnace for
altitude. See Installation Instructions for more information. This
optional method may NOT be used for U.S. installations.
