DocumentDocumentTECHNICAL SPECIFICATIONS J801X* Series High Efficiency Upflow/Horizontal and Downflow Gas Furnaces Induced Draft - 80+% AFUE Input 45,000 - 126,000 BTUH The high efficiency gas furnace may be installed free standing in a utility room, basement, or enclosed in an alcove or closet. The rounded corner jacket provides a pleasing "appliance appearance." Design certified by CSA for application in Canada and the United States. FEATURES and BENEFITS · 100% fired and tested: All units and each component are tested on the manufacturing line. · Low Boy Height: Easy to apply in low ceiling applications, works well with taller high SEER coils, easier to handle and install. · Tubular primary heat exchanger: Heavy gauge aluminized steel heat exchanger assures a long life. · 30 second blower delay at start-up: Assures a warm duct temperature at furnace start-up. Adjustable blower off settings (60, 90, 120 and 180 seconds). · 30 second post purge: Increases life of heat exchanger. · Hot surface igniter: Innovative application of a silicon nitride igniter. · High static blowers: All models equipped with high static blowers. · 90 second cooling cycle blower-off delay (TDR): Increases cooling performance. · Flexible category I venting system: May be vented with dedicated venting system or common vented with other category one appliances. · High efficiency blower kits: Maximize efficiencies. On select units, a SEER improvement of up to 1 point is realized. · Multi-speed direct drive blower: Designed to give a wide range of cooling capacities. Switches on PCB, provide ultra easy motor speed selection. · LP convertible:Simple burner orifice and regulator spring change for ease of convertibility. · Integrated control board: Incorporates connections for electronic air cleaner and humidifier. · Two piece door design: Enhances furnace appearance and uses captured screws to prevent loose door screws. · Meets Title 24 Standards: Min. 350 CFM/Ton, .58 watts/ CFM and 2% cabinet leakage. For California installations in SCAQMD and SJVAPCD only: This furnace does not meet the SCAQMD Rule 1111 and SJVAPCD Rule 4905 NOx emission limit (14 ng/J).
