For side venting of multiple boiler sets, group all intake terminals together with

6" (minimum) lateral spacing, and similarly group the exhaust pipes. Place the
2 groups on the same plane of the building (e.g. north facing wall). Place the 2
groups of pipes at least 3' apart (the closest intake and exhaust pipes shall be
36" - or more – apart. Use same 12" (minimum) vertical separation (See (A) in
Figure 13). Alternately, as long as the boilers are identical models - intake and
exhaust terminals can maintain a minimum of 12" of separation horizontally from
any exhaust or inlet termination of an adjacent boiler (See (B) in Figure 13). For
alternate group terminations, contact the IBC Factory for written guidance.
