INSTALLATION
SFT 199 TANKLESS WATER HEATER
For side venting of multiple units, 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 must be
36" - or more – apart). Use same 12" (minimum) vertical separation (see A in
Figure 12). Alternatively, as long as the units 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 unit (see B in Figure 12). For
alternative group terminations, contact the IBC Factory for written guidance.

design temperature is below 5°F / -15°C. Possible blockage of the combustion air
intake increases when the outdoor temperature drops below this temperature.
