FOR HIGH ALTITUDES:
*HIGH ALTITUDE KIT:
RXGY-F04 (105 KBTU/H)
RXGY-F05 (120 KBTU/H)
RXGY-F06 (45 KBTU/H/60 KBTU/H/90 KBTU/H)
RXGY-F07 (75 KBTU/H)
*For installations over 5000 ft.
OPTION CODE FOR HIGH ALTITUDE: US & Canada – 278
NOTE: High altitude kits and options do NOT include additional burner orifices.
If a burner orifice change is necessary, they must be ordered through
PROSTOCK
®
. See Installation Instructions for more information.
Option – 278 furnaces are shipped with #51 DMS orifices installed. This is
one drill size smaller than standard furnaces to account for expected average
elevations and heating values typically seen in these areas.
CAUTION: Always follow National Fuel Gas Code (NFGC) guidelines when
converting for high altitudes.
For all installations above 2000 ft. (including all option – 278 models), the
burner orifice size needs to be recalculated and verified. A burner orifice
change may still be required. 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.
