GeneralFeatures
NATURAL GAS MODELSCentral Heating furnace designs are certified to ANSI Z21.47 / CSA 2.3 for both natural and L.P. gas. Limit setting and rating data were established and approved under standard rating condi-tions using American National Stan-dards Institute standards.
SAFE OPERATIONThe 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 extra safety.
QUICK HEATINGDurable, cycle tested, heavy gauge alu-minized steel heat exchanger quickly transfers heat to provide warm condi-tioned air to the structure. Low energy power vent blower, to increase effi-ciency and provide a positive discharge of gas fumes to the outside.
BURNERSMultiport Inshot burners will give years of quiet and efficient service. All models can be converted to L.P. gas without changing burners.
INTEGRATED SYSTEM CONTROLExclusively designed operational pro-gram provides total control of furnace limit sensors, blowers, gas valve, flame control and includes self diagnostics for ease of service. Also contains connec-tion points for E.A.C./humidifier.
AIR DELIVERYThe four speed, direct drive blower motor, has sufficient airflow for most heating and cooling requirements, 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.
STYLINGHeavy gauge steel and “wrap-around” cabinet construction is used in the cabinet with baked-on enamel finish for strength and beauty. The heat exchang-er section of the cabinet is completely lined with foil faced fiberglass insulation. This results in quiet and efficient opera-tion 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 OPERATIONThe XR 95 High Efficiency Gas Furnac-es employ a 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.
