A minimum distance below the boiler of 12" is required to provide clearance for the supplied
condensation trap assembly. More clearance will typically be required to accommodate
associated water and gas piping.

3.7 Exhaust venting and air intake

When planning a boiler's installation, consider the appropriate vent materials, travel and
termination.
Warning
Venting, condensate drainage, and combustion air systems for all IBC boilers must be
installed in compliance with all applicable codes and with instructions provided in the
respective installation manuals.
Inspect finished vent and air piping thoroughly to ensure all are airtight, and comply
with the instructions provided as well as with the requirements of applicable codes.
Failure to comply will result in severe personal injury or death.

3.7.1 Venting code

All venting must be installed in accordance with the requirements of the jurisdiction having
authority: in Canada, Part 8, Venting Systems of the CAN/CSA B149.1 Code and any other
local building codes are to be followed. In the USA, the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, latest edition prevails. Where there is a discrepancy between the installation
instructions provided and the code requirements, apply the more stringent.
