Installation Instructions
STEP 1 CONSTRUCT CEILING SUPPORT CONTINUED
•Secure each 2 x 4 block with at least four (4), #10 wood screws, 3” long (not supplied). Use 8 wood screws total for the two supports.
•The cross framing must be accurately aligned to assure correct positioning of the hood.
•The cross framing must be level in all directions. Check with a spirit level and adjust if necessary.
IMPORTANT: The ceiling structure must be capable of supporting the weight of the hood (approximately 300 pounds) and any inadvertent user contact loads. The hood support frame will be supported by the 2 x 4 cross framing.
Ductwork
•Use the shortest and straightest duct route possible. For satisfactory performance, duct run should not exceed 150 feet equivalent length for any duct configuration.
•Refer to “Duct Fittings” chart to compute the maximum permissible length for duct runs to the outdoors.
•This vent hood must use 10” round rigid duct.
•Install the house ductwork to run horizontally between ceiling joists or straight up through the roof.
Finish the Ceiling
•Finish the ceiling surface. Be sure to mark location of the ceiling joists and cross framing. Check to be sure the ceiling is level, use shims if necessary.
