A. GENERAL
These high altitude conversion kits are to be used only
with furnace model numbers *UX-C, *DX-C, *UX-R, *DX-R,
*UY-R, and *DY-R series.
These instructions describe the conversion of these
furnaces for installation exceeding an altitude of 4000 feet
above sea level.
Due to the lower density of air at higher altitudes, there
would be insucient negative pressure developed by
the induced draft blower to maintain normal operation.
Therefore, to compensate for the less dense air, pressure
switches must be changed to prevent nuisance lockouts
and/or cycling of the reduced draft blower on high
speed. Please note that with the reduced ring input
rates required for high altitude installations, the induced
draft blower has ample capacity to provide sucient
combustion air for proper and safe operation. Refer to the
National Fuel Gas Code, Section 8.1.2 and Appendix F, for
information regarding the correct procedure to derate the
furnace's input. The following instructions must be followed
to convert these furnaces for high altitude applications.
B. CONVERSION
The instructions below apply to *UX-C, *DX-C, *UX-R-V,
*DXR-V, *UY-R9V-A, *DY-R9V-A, *UY-R9V-V and *DY-
R9V-V furnace product lines.
1. Check for damage to kit contents, and check for all
items listed in the table.
2. Disconnect electrical supply to furnace, if installed.
3. Remove the wiring connections from the pressure
switch(es) in the furnace. Mark the wires if needed to
properly identify the replacement.
4. Remove the pressure switch(es) sample tube from the
switch assembly.
5. Remove the pressure switch from the unit.
6. Install the new pressure switch in the same location
and manner as the old pressure switch.
7. Connect the pressure switch sample tube and
electrical connections.

8. Reconnect the electrical supply to the unit.
C. CHECKOUT
Once the furnace has been correctly rated for the high
altitude installation, and the pressure switch has been
changed, the furnace installation shall be checked for
proper installation and performance. Refer to the unit
Installer's Guide for checkout procedure.
D. NOTES
1. The use of high altitude calibrated pressure switches
in sea level applications is not permitted.
2. The high altitude pressure switches are factory
calibrated and sealed. Field adjustment is not
permitted. If the factory seal is broken, the product
warranty may be voided.
