Installing the boiler
In the case of flue systems sealed with high temperature
silicon from a cartridge, the silicon must be allowed to
dry for 24 hours before commissioning the boiler.
DANGER: Risk of fatal injury due to poisoning by
escaping flue gas.
▶ After carrying out any of the installations referred to,
check that all connections throughout the entire flue
system are properly joined and sealed.
▶ Check seams and joints for leaks.
▶ Have the entire flue system checked once a year by a
qualified heating contractor.
6.1

Connecting the flue pipe to the boiler

Fit the selected flue system manufacturer's appropriate flue pipe
adaptor for the boiler according to the manufacturer's instructions.
The condensate that forms in the flue pipe can be
drained via the condensate pan. To facilitate this, the
flue pipe must be installed with an upward slope (¼ " per
foot) from the boiler.

Installing the flue system

To ensure perfect operation and prevent foreign bodies entering the flue
system, it must be fitted with a terminal (a T-piece or a 90°-elbow is
required).
In areas subject to heavy snowfalls, the flue system terminal must be at
least 12" higher than the maximum depth of snow.
The flue system must not terminate less than 14 feet above any public
surfaced footway or path.
Make sure that the terminal is at least 10 feet away from the combustion
air intake of any other boiler.
The flue system must terminate more than 6 feet away from any other
opening in a building, from gasometers, equiment controls, combustible
components or similar.
The flue system must terminate at least 4 feet below, 4 feet (6 feet in
Canada) horizontally away from or 1 foot above any door, window or air
vent in any a building.
Ensure a minimum distance of 6" from combustible components.

WARNING: Risk of slipping hazard due to ice formation.
▶ Do not position air intake and flue piping directly
above footways. Dripping condensate can result in ice
formation on the footway.
