Multiple boilers can be connected to a common duct. These flue gas systems for multiple water heater installations
must always be engineered as zero or negative pressure systems; this to prevent the risk of recirculation of the
flue gases. Consult the flue gas supplier for detailed information and engineering. See also the cascade chapter
for these multiple water heater installations.

For use of flex pipe, it is recommended to have the vent material in 0 °C or higher ambient space before bending
at installation. No bends must be made to greater than 45° and ONLY installed in vertical or near vertical installa-
tions.
Stainless steel vent.
This product has been approved for use with stainless steel using the manufacturers listed.
Use only the materials and vent systems listed.
DO NOT mix vent systems of different types or manufacturers. Failure to comply could result
