VENTING DO’S AND DON’TS
DIRECT CONNECT VENTING EXAMPLES
Example 3
shows an incorrect
installation where an additional vent
was added to the wall behind the oven,
creating an air pressure difference
causing air movement beneath the oven
and disrupting the operation of the oven
burners� This air movement can be so
severe as to cause a downdraft, pulling
the exhaust down the oven flue and
backwards through the burners, leading
to heat damage of oven components�
3. Unacceptable venting
Neutral room
air pressure
Exhaust flow
direction is
reversed
Equal air pressure
inside and outside of
oven room
Low pressure is created
by HVAC or any air
moving equipment
outside the oven room
Exhaust air is pulled
backwards through
oven burners
An added vent
intended to increase
air supply
Airflow to oven is
altered as air moves
from normal to low
pressure
Example 4
shows an incorrect
installation where the enclosure
surrounding the oven is open to the
attic space above the ceiling� Air
can move rapidly through the space
enclosing the oven to the lower
pressure area within the attic space�
This can cause a downdraft situation
at the oven, pulling air and heat
backwards through the oven burners,
leading to damage of oven components�
4. Unacceptable venting
Air flow
Low pressure area
Exhaust
flow
direction is
reversed
Combustion air is
diverted from oven
burners because
room is open to a
low pressure area.
Exhaust air is
pulled backwards
through oven
burners.
False ceiling
