WARNING!
only.
Connection of another boiler may
cause serious injury or death.
The flue pipes must not be routed into
another vent. In addition, the pipes of
the flue system must not be routed
through another vent or inside another
vent, such as with an existing brick or
factory-manufactured chimney lining.
FIRE DANGER
due to insufficient clearance between flue
pipe and flammable building components.
WARNING!
Make sure that there is a minimum
clearance of two (2) inches to
flammable building components.
No minimum clearance is required
between the wall penetration and
flammable building components.
The vent pipe must be securely fastened. Vertical
venting pipes must be fixed with a fire protection collar
at every ceiling penetration and fixed with at least one
retainer at the base of vertical pipe.
The flue system pipes must be fixed with retainer bands
along their length in the vicinity of all elbows and
connections and at intervals of at least 48 inches.
When installing fastening components do not drill holes
into any of the components of the flue system when
joining pipes or fittings or when installing retainer bands.
If pipe lengths are cut to size, the cut edges must be filed
or ground smooth before joining them. The coupling end
of the pipe must not be cut.
Make sure that all horizontal venting pipes have a slope
of at least 1/4 inch per foot. All horizontal venting pipes
must have a downward slope to the boiler to prevent any
accumulations of moisture in the flue system.
The flue system is under overpressure. Silicone sealant
must be left to dry for 24 hours before putting the boiler
into operation.
RISK TO LIFE

WARNING!
installation instructions always check
that all connections in the complete flue
system are correctly joined and sealed.
Check the seams and joints for leaks.
Have the complete flue system
checked by a technician once a year.
We reserve the right to make any changes due to technical modifications.
