They may be either side wall or thru-roof vented usingapproved plastic type combustion air and vent piping.

2 Allunits are factory assembled, wired and tested to assuredependable and economical installation and limited WARRANTY on both heat exchangers to the orig-inal purchaser; a 20-year limited WARRANTY from original instal-lation date to subsequent WARRANTY on the heat exchanger in commercial limited parts Compact, easy to install, ideal height 40" cabinet Blower-off delay for cooling SEER improvement. Easy to connect power/control wiring. Built-in, high level self diagnostics with fault code display. Low unit amp requirement for easy replacement applica-tion. Integrated control module for reliable, economical opera-tion. May be installed as either two-pipe (sealed combustion) or single pipe vent (using indoor combustion air) Top intake & vent connection allows downflow installa-tion in narrow locations.

3 Electronic Hot Surface Ignition saves fuel cost with increased dependability and reliability. Induced combustion system with inshot main burners for quiet, efficient operation. No special vent termination kit required. 100% shut off main gas valve for extra safety. PSC four speed, direct drive motor with large, quiet blower. 24V, 40 VA control transformer and blower relay supplied for add-on cooling. Hi-tech tubular aluminized steel primary heat exchanger. Secondary (condensing) heat exchanger of 29-4C high-grade stainless steel. Timed on, adjustable off blower capability for maximum comfort. Easy access from front of unit for cleaning, maintenance or service. Protection from intake, exhaust or condensate Products Group339033-YTG-A-0607 Annual Fuel Utilization Efficiency (AFUE) numbers are determined in accordance with DOE Test size and over current protection must comply with the National Electrical Code (NFPA-70-latest edition) and all local furnace shall be installed so that the electrical components are protected from size and overcurrent protection must comply with the National Electric : 1.
