GeneralFeatures

NATURAL GAS MODELSCentral Heating furnace designs arecertified to ANSI Z21.47 / CSA 2.3 forboth natural and L.P. gas. Limit settingand rating data were established andapproved under standard rating condi-tions using American National StandardsInstitute standards.

SAFE OPERATIONThe Integrated System Control has solidstate devices, which continuously monitorfor presence of flame, when the system isin the heating mode of operation. Dualsolenoid combination gas valve andregulator provide extra safety.

QUICK HEATINGDurable, cycle tested, heavy gaugealuminized steel heat exchangerquickly transfers heat to provide warmconditioned air to the structure. Lowenergy power vent blower, to increaseefficiency and provide a positive dis-charge of gas fumes to the outside.

BURNERSMultiport Inshot burners will give years ofquiet and efficient service. All modelscan be converted to L.P. gas withoutchanging burners.

INTEGRATED SYSTEM CONTROLExclusively designed operational pro-gram provides total control of furnacelimit sensors, blowers, gas valve, flamecontrol and includes self diagnostics forease of service. Also contains connec-tion points for E.A.C./humidifier.

AIR DELIVERYThe four speed, direct drive blowermotor, has sufficient airflow for mostheating and cooling requirements, willswitch from heating to cooling speeds ondemand from room thermostat. Theblower door safety switch will prevent orterminate furnace operation when theblower door is removed.

STYLINGHeavy gauge steel and “wrap-around”cabinet construction is used in thecabinet with baked-on enamel finish forstrength and beauty. The heat ex-changer section of the cabinet is com-pletely lined with foil faced fiberglassinsulation. This results in quiet andefficient operation due to the excellentacoustical and insulating qualities offiberglass. Built-in bottom pan andalternate bottom, left or right side returnair connection provision.

FEATURES ANDGENERAL OPERATIONThe XR 95 High Efficiency Gas Furnacesemploy a Silicon Nitride Hot SurfaceIgnition system, which eliminates thewaste of a constant burning pilot. Theintegrated system control lights the mainburners upon a demand for heat from theroom thermostat. Complete front serviceaccess.

a. Low energy power venter

b. Vent proving pressure switch.
