MAXIMUM ALLOWABLE EXPOSED VENT PIPE LENGTH (FT) WITH AND WITHOUT INSULATION
IN WINTER DESIGN TEMPERATURE AMBIENT*
* Pipe length (ft) specified for maximum vent pipe lengths located in unconditioned spaces. Vent pipes located in unconditioned space cannot
exceed the total allowable pipe length as specified in Maximum Allowable Pipe Length table.
† Insulation thickness based on R value of 3.5 per in.
Performance data
EFFICIENCY
*
Capacity and AFUE in accordance with U.S. Government DOE test procedures.
† Gas input ratings are certified for elevations to 2000 ft. For elevations above 2000 ft, reduce ratings 2% for each 1000 ft above sea level. In Canada, derate
the unit 5% for elevations 2000 to 4500 ft above sea level.
‡ Airflow shown is for bottom only return-air supply. For air delivery above 1800 CFM, see Air Delivery table for other options. A filter is required for each
return-air supply.
