Frequently Asked Questions - JDH236C3SS Vent-A-Hood

What is the recommended installation height above the cooking surface?

The bottom edge of the hood should be no more than 30" above the cooking surface for optimum performance.

Can I use flexible duct for this range hood?

No, only smooth galvanized metal duct is allowed. Flexible or corrugated duct will restrict airflow and reduce performance.

What size duct do I need for a single or dual blower?

Single blower (B100) requires 6" round duct (28 sq in). Dual blower (B200) requires 8" round duct (50 sq in). Never reduce the duct size.

How do I clean the E-Z Clean shield?

The E-Z Clean shield is removable. Lightly pull it toward the front of the hood to remove. It can be washed with mild detergent and water. Ensure it is dry before reinstalling.

How do I access the blower motor for maintenance?

First, remove the E-Z Clean shield. Then unsnap the suitcase latches on each side of the blower housing. Pull the housing forward and gently tip it to clear the blower wheel. Then remove the three screws retaining the motor and unplug it.

What is the difference between CFM and Equivalent CFM?

Equivalent CFM is a measure of the Magic Lung blower efficiency compared to conventional baffle or mesh filters. For example, the dual blower delivers 600 CFM (SP 0.0") but achieves 900 Equivalent CFM due to centrifugal filtration.

Can I terminate the vent in an attic or chimney?

No, the duct must be vented to the outdoors. Do not terminate in an attic or chimney. Use a wall louver or roof jack with a gravity damper.

What electrical requirements are needed?

The hood requires 115V, 60Hz power. Each motor box needs a separate circuit. Use a 1/2" UL listed electrical clamp. The current draw is up to 4.0A for dual blower. Ensure proper grounding.

How many blower configurations are available?

The hood supports up to four configurations: single blower (B100), dual blower (B200), single+dual (B100+B200), or two duals (2xB200). Each requires different duct sizes and transitions.

What is the noise level in sones?

The sound level is 5.4 sones for single blower and 6.5 sones for dual blower at normal operation. Higher CFM settings may increase noise.

Because the Magic Lung® blower uses centrifugal filtration rather than conventional baffle or mesh filters, the Magic Lung® blower can handle cooking equipment with higher cubic feet per minute (CFM) requirements and can deliver equivalent CFM much more efficiently than other filtration systems. When comparing the Magic Lung® with other blower units made by other manufacturers, use the "Equivalent CFM". Ratings in accordance with the Standard Test Code by the Energy Systems Laboratory of the Texas Engineering Experiment Station.

8) If using a duct cover, remove the duct cover from its packaging and remove the mounting screws from the base of the duct cover. Place the duct cover on the top of the hood and secure it through the knockout openings using the mounting screws previously removed.

Lift the hood or the hood and duct cover assembly to the location on the wall where it will be installed. Lightly mark the wall with a short, horizontal mark along the bottom edge of the hood. When finished, remove the hood or hood and duct cover assembly from the wall. If applicable, leave the duct cover installed on the hood.

9) Remove the hood from the wall. On the back side of the hood, measure the distance between the bottom edge of the hood and the top edge of the wood mounting strip. Measure this distance above the horizontal line made in Step 8 and lightly mark the wall with a level, horizontal line. Measure where the center (left to right) of the hood will be and mark the upper, horizontal line on the wall with a short, vertical centerline.
10) Remove the screws inside the top of the back of the hood that retain the wood strip that is recessed in the mounting channel. Note: Some retaining screws may be located behind the blower(s). Remove the wood mounting strip from the back of the hood and place the top edge of the strip on the upper, level horizontal line on the wall. Referencing the vertical centerline from Step 9, place the mounting strip on the wall so it is centered (left to right) in the space where the hood will be located. Drill pilot holes in the strip to prevent splitting. Using proper hardware, attach the mounting strip to at least two wall studs.

11) FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY TO STEP 12.

Note: Wall studs may interfere with back venting installations. Additional framing may be required. It is necessary to cut a duct access hole in the wall prior to installing the hood.

To accomplish this, first remove and set aside any duct cover that was previously installed in Step 8. Hold the hood on the mounting strip by aligning the channel at the top of the back of the hood over the wood mounting strip on the wall. Place the appropriate elbow on top of the hood in line with the hood exhaust collar. On the wall, trace around the elbow. Remove the hood and elbow from the wall. Cut around the outside of the traced line, avoiding wall studs. Install the duct from the outside of the home to the opening in the wall. Use duct tape to seal joints. If applicable, place the duct cover back onto the top of the hood and reattach it to the hood.
12) Hang the hood on the mounting strip by aligning the channel at the top of the back of the hood over the wood mounting strip on the wall. While holding the hood in place, mark locations on the mounting strip through the two mounting holes in the channel at the top of the hood. Some mounting holes may be located behind the blower(s). Remove hood and drill 3/32" pilot holes at the center of marks in the wood strip to prevent splitting.
13) FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY TO STEP 14.
Place the appropriate elbow on the top of the hood. The elbow should be placed with the non-crimped end on the inside the collar of the exhaust outlet. Use duct tape to seal joint. Insert the electrical wire(s) from the service panel into the electrical wire clamp on each motor box. Tighten the wire clamp(s). While securing the slack in the wire(s), lift the hood (and duct cover) up to the wall and hang the hood on the mounting strip, taking care to properly align the duct connection between the elbow on the hood and the duct in wall. Secure the hood to the mounting strip by installing the screws (previously removed in Step 10) into the pilot holes drilled in Step 12. SKIP STEPS 14 AND 15. PROCEED DIRECTLY TO STEP 16.
14) Insert the electrical wire from the service panel into the electrical wire clamp on each motor box. Tighten the wire clamp(s). Cut a piece of duct of sufficient length to meet the duct in the ceiling allowing room for the transition (if applicable). If a transition is used, cut the duct to reach the transition outlet plus 1". This will allow the transition to engage 1" inside of the duct. See Page 3 for transition heights. One end of the duct must be crimped to fit inside the duct in the ceiling. Insert the non-crimped end over the transition or into the exhaust collar on the top of the hood and seal with duct tape.
15) While securing the slack in the wire(s), lift the hood (and duct cover) up to the wall and hang the hood on the mounting strip, taking care to properly align the duct connection between the hood and the duct in the ceiling. Secure the hood to the mounting strip by installing the screws (previously removed in Step 10) into the pilot holes drilled in Step 12.
16) From inside the hood, using UL listed wire nuts, attach the "neutral" wire(s) to the white lead(s), the "hot" wire(s) to the black lead(s), and the ground wire(s) to the green lead(s) inside the motor box(es).

Warning: Do not operate hood without proper ground connection.

17) Plug the motor(s) into the hood and reinstall the blower motor(s) using the three retaining screws that were previously removed in Step 6.
18) Replace the blower housing(s) and the E-Z Clean shield(s). Make sure that the damper(s) open and close smoothly.
19) Refer to the Owner Maintenance Guide Operating Instructions for proper hood operation. Test all blower and light functions to ensure they are operating properly.
