intake or exhaust pipe length. What is the altitude? 7 Furnace capacity? FIGURE 21 MINIMUM VENT PIPE LENGTHS IMPORTANT Do not use screens or perforated metal in exhaust or intake terminations. Doing so will cause freeze-ups and may block the terminations. *Any approved termination may be added to the minimum length listed. **This gas furnace must have 3” to 2” reducing ell (supplied or field replacement Canadian kit) installed directly into unit flue collar.
