*Gas cooktops must use 5" (12.7 cm) diameter for runs of 10' (3.0 m) or less.
**May be used to vent straight out the back of the cooktop and directly
through the wall.
CALCULATING MAXIMUM DUCTING LENGTH
• Maximum ducting length is 60' (18.3 m).
• Each 90° elbow equals 5' (1.5 m) duct.
• Use no more than three 90° elbows.
• Flexible metal vent is not recommended.
• Do not install two elbows together.
NOTES:
• For ducting runs up to 30' (9.1 m), install cooktop as shipped.
• For ducting runs of 31' (9.4 m) to 60' (15.2 cm), remove the restricter ring
on the blower inlet housing.
• For altitudes above 4500' (1272.0 m), reduce recommended vent run by
20% for best performance.
