User manual THERMADOR LI164AINST

[. . . ] Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturers guideline and safety standards such as those published by the National Fire Protection Association (NFPA), the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities. CAUTION: To reduce risk of fire and to properly exhaust air, be sure to duct air outside - do not vent exhaust air into spaces within walls, ceilings, attics, crawl spaces, or garages. [. . . ] For the most efficient air flow exhaust, use a straight run or as few elbows as possible. The hood is fitted with Screws and Drywall Anchors suitable for most surfaces, consult a Qualified Installer, check if they perfectly fit with your cabinet/wall. COLD WEATHER installations should have an additional backdraft damper installed to minimize backward cold air flow and a nonmetallic thermal break to minimize conduction of outside temperatures as part of the ductwork. The break should be as close as possible to where the ducting enters the heated portion of the house. Make up air: Local building codes may require the use of Make-Up Air Systems when using Ducted Ventilation Systems greater than specified CFM of air movement. Consult your HVAC professional for specific requirements in your area.

Page 8 BEFORE INSTALLING HOOD TYPICAL INSTALLATION The hoods are designed for either vertical or horizontal discharge as shown in Figure A and B respectively. The height from the countertop to the bottom of the hood is 30" to 36". These hoods are not recommended to be used over indoor grills. DUCTING Provide a Round Duct having a diameter of 8 (see Figure A and B for location and Figure 1 for location on wall or cabinet bottom). Install a 1/2 conduit from the service panel long enough to reach the hood once it is installed. Power supply must be rated for 120V 60Hz, 15 amps (minimum). Note - Horizontal Discharge: The Transition for this discharge direction is not supplied and must be purchased separately. Page 9 BEFORE INSTALLING HOOD Discharge Direction: The hood is shipped ready for horizontal discharge. To change to vertical discharge move plate to the rear side and ventilator (if supplied) to the top side. The plate and ventilator are held in place by four nuts each, see also Figures 3 and , at page 9, Figure A and Figure B. Read also paragraph Integral Ventilator Installation at pages 14-15 for further informations. Note: If an integral ventilator is already supplied (HSB series hoods only), remove it to allow installation of hood to the wall/cabinet. Assembly of the Transition: The transition supplied with the hood mounts to the top of the hood, Figure 4. Align mounting holes at base of transition with mounting holes on 1/2 flange located at the top of the hood. [. . . ] Connect black, white, and green wires from power supply to black, white, and green/ yellow wires in j-box respectively. Insert pigtail wires into j-box and fix wire clamp to j-box using nut supplied with wire clamp V. Run five wires (#14 AWG) in 1/ 2 conduit from the remote blower to the second conduit connector. Connect the black, white, red, and blue wires from the remote ventilator to the black, white, red, and blue wires of the pigtail respectively. [. . . ]
