1. Two openings are recommended for airflows above 1,600 CFM if filter(s) is(are) adjacent to furnace
2. Temperature rises in the table are approximate. Actual temperature rises may vary.
3. Temperature rises shaded in gray are for reference only. These conditions are not recommended

VENTING

• All models are approved for vertical non direct (1 pipe) and direct (2 pipe) venting applications. See Vent Table below for specified sizes and allowable lengths.

VENT TABLE

NOTE

1. Subtract 2.5 ft. for each additional 2″ elbow and 3.5 ft. for each additional 3″ elbow.
2. Two 45 degree elbows are equivalent to one 90 degree elbow.
3. One short radius elbow is equivalent to two long radius elbows.
4. Do not include termination elbows in calculation of vent length.
5. This table is applicable for elevations from sea level to 2000 ft. For higher elevations decrease vent pipe lengths by 8% per 1000 ft. of altitude. 6. Only the listed pipe materials are approved for use with FG7 Condensing Furnaces.

SPECIFICATIONS

Note: All models are 115V, 60 Hz. Gas Connections are 1/2″ N.P.T. AFUE = Annual Fuel Utilization Efficiency

• Ratings to 2,000 ft. Over 2,000 ft. reduce 4% for each 1,000 ft. above sea level.
