GAS PIPING CHECKS
Before placing unit in operation or after servicing, leak test
gas connections.
WARNING
T
O A V O I D TH E PO SSI BL I TY OF EX PLO SI ON O R F IRE , N EVER USE A M ATCH
O R OP E N FLA ME TO T ES T FO R L E A KS .
Check for leaks using an approved chloride-free soap and
water solution, an electronic combustible gas detector, or
other approved testing methods.
NOTE: Never exceed specified pressures for testing. Higher
pressure may damage the gas valve and cause subsequent
overfiring, resulting in heat exchanger failure. Disconnect
this unit and shutoff valve from the gas supply piping system
before pressure testing the supply piping system with
pressures in excess of 1/2 psig (3.48 kPa). Isolate this unit
from the gas supply piping system by closing its external
manual gas shutoff valve before pressure testing supply
piping system with test pressures equal to or less than 1/2
psig (3.48 kPa).

HIGH ALTITUDE DERATE
The furnace, as shipped, requires no change to run between
0-4500 feet. At all altitudes the air temperature rise must be
within the range listed on the Specification Sheet ap¬plicable
to your model for the fuel used. Manifold pressure adjustments
and combustion analysis are required for all installations
above 4500 ft. Refer to “Gas Supply Pressure Measurement”
section for instruction on how to properly measure and adjust
manifold “outlet” pressure. The furnace should operate
for a minimum of 15 minutes before taking a combustion
sample. Combustion samples should be taken from beyond
the furnace exhaust and must be within provided CO2%
range. See table 3 for recommended manifold pres¬sure
adjustments and proper CO2% range. Gas heating val¬ues
can vary; further pressure adjustment may be necessary to
ensure furnace operates within acceptable CO2 range.

TSRK02
Two Stage Releay Kit. For use with single stage Ultra-Low
NOx furnaces with multi-speed (constant torque) ECM motors.
The TSRK02 allows connection of *MES96 ULN constant
torque furnace to be paired with a two-stage air conditioner
or two-stage heat pump to provide different indoor fan speeds
during Y1 and Y2 cooling or heat pump operation.

WIRING HARNESS
The wiring harness is an integral part of this furnace. Field
alteration to comply with electrical codes should not be
required. Wires are color coded for identification purposes.
Refer to the wiring diagram for wire routings. If any of the
original wire as supplied with the furnace must be replaced,
it must be replaced with wiring material having a temperature
rating of at least 105° C. Any replacement wiring must be
copper conductor.
