High Elevation (>2,000 Feet/609 Meters) Installations
NOTES:
• High elevation (>2,000 feet/609 meters) application with this unit depends on the installation
elevation and the heating value of the gas. At high elevations, the heating value of natural gas is
always lower than the heating value at sea level.
• Deration is necessary to compensate for low atmospheric pressure at high elevations. Generally
this will require obtaining the gas heating value from the local gas utility and replacing the burner
orifices.
For high elevation (>2,000 feet/609 meters) installations that require orifice replacement, replace the burner orifices
as follows:
1. Determine model number and rated input (BTUh) from unit’s rating plate.
2. Determine appropriate orifice replacement (refer to Table 18) for installation elevation.
3. Unthread existing gas orifices from gas manifold.
⚠ DANGER ⚠
• Do not use Teflon tape or pipe joint compound on the orifice threads. The hole in the orifice may
become blocked and may cause fire, explosion, property damage, carbon monoxide poisoning,
personal injury, or death.
• Use only using factory-supplied orifices. Do not attempt to drill out orifices in the field. Improperly
drilled orifices may cause fire, explosion, carbon monoxide poisoning, personal injury, or death.
4. Thread replacement gas orifices into gas manifold. To prevent cross-threading, hand-tighten orifices into gas
manifold until snug and then tighten one-half to one turn using wrench.
⚠ DANGER ⚠
DO NOT use an open flame to check for gas leaks.
5. Check all connections for gas leaks using commercial leak-detecting fluid or rich soap and water solution. Leaks
are indicated by presence of bubbles. If leak is detected, tighten connection. If leak cannot be stopped by tightening
connection, replace part(s).
Conversion to LP (Propane)
⚠ DANGER ⚠
Conversion to LP (propane) gas must be performed by qualified service personnel using a factory-
supplied conversion kit. Failure to use the proper conversion kit can cause fire, explosion, property
damage, carbon monoxide poisoning, personal injury, or death.
If LP (propane) conversion is required, convert the unit in accordance with form OPT-GC listed in Table 1. When
conversion is complete, verify that the input rate is correct.
