MODULATING OPERATION

The modulating gas valves provides
longer heating cycles for more
consistent heating comfort. Modulates
from 40% (45% for the TUHMD120)
to 100% in less than 1% increments
of the furnace's heating capacity
saving energy, while at the same
time maximizing homeowner comfort.

COMMUNICATING MODE

Furnace is shipped ready to be
connected in communicating mode
using three wire hook-up using the
TZONE950 or the TCONT900 comfort
control.

ALTERNATE 24V MODE

Furnace is field configurable to 24V
non-communicating mode.

COMFORT CONTROL

Comfortlink IITM Communicating furnace
design, offers plug and play – walk away
installation. Assures the entire heating
and air conditioning system is set up
in the proper modes to optimize the
engineered performance of the matched
system installed. The furnace can also
be connected in conventional 24V mode.

NATURAL GAS MODELS

Central Heating furnace designs are cer­tified by the American Gas Association
for both natural and L.P. gas. Limit setting
and rating data were established and ap­proved under standard rating conditions
using American National Standards Insti­tute standards.

SAFE OPERATION

The Integrated System Control has solid
state devices, which continuously monitor
for presence of flame, when the system
is in the heating mode of operation. Dual
solenoid combination gas valve and reg­ulator provide additional safety.

QUICK HEATING
Durable, cycle tested, heavy gauge alu­minized steel heat exchanger quickly

transfers heat to provide warm condi­tioned air to the structure. Low energy
power vent blower, to increase efficien­cy and provide a positive discharge of
gas fumes to the outside.

BURNERS

Multiport Inshot burners will give years of
quiet and efficient service. All models can
be converted to L.P. gas without chang-
ing burners.

INTEGRATED SYSTEM CONTROL

Exclusively designed operational pro­gram provides total control of furnace
limit sensors, blowers, gas valve, flame
control and includes self diagnostics for
ease of service. Also contains connection
points for EAC and Humidifier hookup.

AIR DELIVERY

The variable speed blower motor has
sufficient airflow for most heating and
cooling requirements and will switch from
heating to cooling speeds on demand
from room thermostat. The blower door
safety switch will prevent or terminate
furnace operation when the blower door
is removed.

SECONDARY HEAT EXCHANGER

The XC95m has a special type 29-4C™
stainless steel secondary heat exchang­er to reclaim heat from flue gases which
would normally be lost.

STYLING
Heavy gauge steel and “wrap-around”
cabinet construction is used in the

cabinet with baked-on enamel finish for
strength and beauty. The heat exchang­er section of the cabinet is completely
lined with foil faced fiberglass insulation.
This results in quiet and efficient opera­tion due to the excellent acoustical and
insulating qualities of fiberglass. Built-in
bottom pan and alternate bottom, left or
right side return air connection provision.

FEATURES AND GENERAL
OPERATION

The XC95m High Efficiency Gas Fur­naces utilize an Adaptive Heat Up Silicon
Nitride Hot Surface Ignition system, which
eliminates the waste of a constant burn­ing pilot. The integrated system control
lights the main burners upon a demand
for heat from the room thermostat. Com­plete front service access.
a. Low energy power venter
b. Vent proving pressure switch.

NOTE:
CONTINUOUS fan mode during COOLING operation
may not be appropriate in humid climates. If the
indoor air exceeds 60% relative humidity or simply
feels uncomfortably humid, it is recommended that
the fan only be used in the AUTO mode.

1. Minimum vent length for all models: 3' horizontal or 3' vertical

2. DO NOT MIX PIPE DIAMETERS IN THE SAME LENGTH OF PIPE OUTSIDE THE FURNACE CABINET, (Except
adapters at the top of the furnace). If different inlet and vent pipe sizes are used, the vent pipe must adhere to the
maximum length limit shown in the table above (See note 6 below for exception). The inlet pipe can be of a larger
diameter, but never smaller than the vent pipe.

3. MAXIMUM PIPE LENGTHS MUST NOT BE EXCEEDED! THE LENGTH SHOWN IS NOT A
COMBINED TOTAL, IT IS THE MAXIMUM LENGTH OF EACH (Vent or Inlet air pipes).

4. One SHORT radius 90° elbow is equivalent to 10' of 3" pipe and one LONG radius elbow is equivalent to 6' of 3"
pipe. One 90° elbow is equivalent to 7½' of 2½" pipe or 5' of 2" pipe. Two 45° elbows equal one 90° elbow.

5. The termination tee or bend must be included in the total number of elbows. If the BAYAIR30AVENTA termination
kit is used, the equivalent length of pipe is 5 feet. BAYVENT200B equivalent length is 0 feet.

6. Pipe adapters are field supplied. Downflow models, UHM 100 and UHM 120 models include
the 2" x 3" adapter.

IPEX 196009 = 5 feet, IPEX 081216 = 11 feet, IPEX 081218 = 16 feet, and IPEX 081219 = 21 feet

NOTE:
The maximum total cable length for the entire Comfort
Control communicating system is 500 ft. 18 AWG. The
maximum distance of any single cable from a trans­former is 250 ft. 18 AWG.

NOTE:
When connecting an TFD whole house air cleaner with
this furnace, order BAYACCECOMM101.

NOTE:
The BAYACCECOMM101 must be used when
connecting an TFD whole house air cleaner to a
furnace in communicating mode. For 24 volt mode,
see the installation in the whole house air cleaner
Installer's Guide.

NOTE:
The BAYACCECOMM101 can be ordered through the
sales channels.

NOTE:
The B/C terminal will require three wires to be
connected. Rather than connecting the three wires to
the low voltage terminal strip, create a pigtail using a
short length of thermostat wire and a wire nut (field
supplied) to attach to the B/C terminal.
