NATURAL GAS AND LP GAS INSTALLATIONS AT ALTITUDES > 2000 FT.
High Altitude Derate - U.S. Installations Only
I
MPORTANT NOTE:
The gas/electric units naturally derate with altitude. Do not attempt to increase the firing rate by
changing orifices or increasing the manifold pressure. This can cause poor combustion and equipment failure. At all
altitudes, the manifold pressure must be within 0.3 inches W.C. of that listed on the nameplate for the fuel used. At all
altitudes and with either fuel, the air temperature rise must be within the range listed on the unit nameplate. Refer to the
Installation Manual provided with the LP kit for conversion from natural gas to propane gas and for altitude adjustments.
When this package unit is installed at high altitude, the appropriate High Altitude orifice kit must
be installed. As altitude
increases, there is a natural reduction in the density of both the gas fuel and combustion air. This kit will provide the proper
design certified input rate within the specified altitude range. High altitude kits are not approved for use in Canada. For
installations above 2,000 feet, use kit HAKT36300. The HAKT36300 kit is used for both Natural and LP gas at high altitudes.
Use LPKT36150 or LPKT180300 propane conversion kit for propane conversions at altitudes below 2000 feet. Natural gas
installations below 2000 feet do not require a kit.
For propane conversions above 2000 feet, high altitude kit HAKT36300 is required in addition to LPKT36150 or LPKT180300
propane conversion kit.
