Jenn-Air Range - Manuel (Page 6)

6
The length of vent system and number of elbows should be kept
to a minimum to provide efficient performance.
The maximum equivalent length of the vent system is 60 ft
(18.3 m). For altitudes above 4,500 ft (1272 m), reduce
recommended vent run by 20% for best performance.
Cold Weather Installations
An additional backdraft damper should be installed to minimize
backward cold air flow and a thermal break installed to minimize
conduction of outside temperatures as part of the vent system.
The damper should be on the cold air side of the thermal break.
Makeup Air
Local building codes may require the use of makeup air systems
when using ventilation systems greater than specified CFM of air
movement. The specified CFM varies from locale to locale.
Consult your HVAC professional for specific requirements in your
area.
Venting Methods
Common venting methods are shown for a downdraft range. The
downdraft range may be vented through the wall or floor.
