higher. They may be either side wall or thru-roof vented using
approved plastic type combustion air and vent piping. All
units are factory assembled, wired and tested to assure
dependable and economical installation and operation.
WARRANTY
Lifetime limited warranty on both heat exchangers to the original purchaser; a 20-year limited warranty from original installation date to subsequent purchaser.
10-year warranty on commercial applications.
5-year limited parts warranty.

Annual Fuel Utilization Efficiency (AFUE) numbers are determined in accordance with DOE Test procedures.
Wire size and over current protection must comply with the National Electrical Code (NFPA-70-latest editio n) and all local codes.
The furnace shall be installed so that the electrical components are protected from water.
* Wire size and overcurrent protection must comply with the National Electric Code.
NOTES:
1. For altitudes above 2000 ft. reduce capacity 4% for each 1000 ft. above sea level.
2. Wire size based on copper conductors, 60°C, 3% voltage drop.
3. Continuous return air temperature must not be below 55°F.
4. All filters must be high velocity cleanable type.
