Fig. 33—Sidewall Termination of 12 in. or More
or breach vent 58MXA furnaces. When 2 or more 58MXA
furnaces are vented near each other, 2 vent terminations may be
installed as shown in Fig. 35, 36, 37, 38, or 39, but next vent
termination must be at least 36 in. away from first 2 terminations.
It is important that vent terminations be made as shown to avoid
recirculation of flue gases. Dimension "A" in Fig. 35, 36, 37, 38,
and 39 represents distance between pipes or rain shields, as
touching or 2-in. maximum separation.
