WARNING
Danger of toxic fumes.
Gas cooking appliances release
carbon monoxide that can be
harmful or fatal if inhaled.
To reduce the risk of fire and to
properly exhaust air, the exhaust
gases extracted by the ventilation
system should be only vented to
the outside of the building.
Do not vent exhaust air into
spaces within walls or ceilings or
in attics, crawl spaces or garages.
To reduce the risk of fire, only use
metal ductwork.
Please read and follow the
"IMPORTANT SAFETY
INSTRUCTIONS" to reduce the risk of
personal injury. Follow all local building
codes when installing the ventilation
system.
Exhaust ducting and connections
–
The ducting should be as short and
straight as possible, and the number
of sharp bends should be minimized.
–
For most efficient air extraction, the
diameter of the ductwork should not
be less than 6" (150 mm)*. Use of flat
ducts also reduces the air extraction
efficiency.
–
Noise levels of the ventilation system
will increase if flat ducts or round
ducts of less than 6" (150 mm)* in
diameter are used.
– Use smooth or flexible pipes made
from approved non-flammable
materials for exhaust ducting.
– Where the ductwork is horizontal, it
must slope away from the ventilation
system at least
1
/
8
" per foot (1 cm per
meter) to prevent condensation
dripping into the appliance.
–
If the exhaust is ducted into an
unused flue, the air must be expelled
parallel to the flow direction of the
flue.

vent motor.
