In order to relocate the switch, locate 2 mounting holes or drill above the inducer pressure tap. When drilling the 2 holes make sure to keep the switch and tubing far enough away from the burners or hot sur faces as to not melt the hose, switch, or wires. To prevent possible 3. Side Venting This furnace is shipped from the factory with the venter assembly in an upflow configurations (top vent). The venter assembly can easily be rotated to a side vent configurations for use in upflow, horizontal-flow, or downflow application. When using a side vent configuration (side outlet instead of top outlet), it may be necessary to relocate the pressure switch to the alternate position on the opposite side of the top panel. Two screw holes are provided at the alternate position. Route the pressure switch tubing so the tubing is not kinked and not touching the hot collector box, venter housing, or motor. It may be necessary to shorten the length of the tubing to properly route the tubing and eliminate kinks. Rotating the Venter Assembly 1, If gas and electrical power have already been connected to unit shut off gas and remove power from unit. Unscrew screws on burner compartment door and remove burner compartment door. (see Figure 6). 2, Disconnect power leads to the venter motor and hose to pressure switch. Remove three (3) or four (4) screws which secure the venter to the collector box, (see Figure 7). 3, Cut webbing with a pair of snips holding the vent plate to the cabinet on either the left or right side of unit depending on right or left venting as desired. Discard vent plate, (see Figure 6). 4, Replace venter gasket (part # 1013540, if needed) to venter assembly with adhesive in the same location as the old one. 5. Clip the wire tie for the venter wires, if needed. 6. Rotate venter assembly 90 ° right or left from original location depending on venting configurations. kinking of the pressure switch hose, trim the hose to remove excess length. Note: When drilling new holes make sure metal shavings do not fall on or in components, as this can shorten the life of the furnace.

Tighten the three (3) or four (4) screws that secure the venter assembly to the collector box. Do tighten screws enough to compress venter gasket. 8. Replace power leads to venter motor and reconnect hose to pressure switch. 4. Combustion & Ventilation Air CARBON MONOXIDE POISONING HAZARD. Failure to provide adequate combustion and ventilation air could result in death or personal injury. Use methods described here to provide combustion and ventilation air. Furnaces require ventilation openings to provide sufficient air for proper combustion and ventilation of flue gases. All duct or open ings for supplying combustion and ventilation air must comply with the gas codes, or in the absence of local codes, the applicable national codes. Combustion and ventilation air must be supplied in accordance with one of the following: 1. Section 8.3, Air for Combustion and Ventilation, of the National Fuel Gas Code, (NFGC), ANSI Z223.1-2002/NFPA 54-2002 in the U.S., 2. Sections 7.2, 7.3, 7.5, 7.6, 7.7, and 7.8 of National Standard of Canada, Natural Gas and Propane Installation Code (NSCNGPIC), CSA B149.1-05 in Canada, 3. Applicable provisions of the local building code. When the installation is complete, check that all appliances have adequate combustion air and are venting properly. See Venting And Combustion Air Check in %. Gas Vent Installation "Section in this manual. Contaminated Combustion Air Installations in certain areas or types of structures could cause ex cessive exposure to contaminated air having chemicals or halogens that will result in safety and performance related problems and may harm the furnace. These instances must use only out door air for combustion. The following areas or types of structures may contain or have ex posure to the substances listed below. The installation must be evaluated carefully as it may be necessary to provide outdoor air for combustion. • Commercial buildings. • Buildings with indoor pools. • Furnaces installed in laundry rooms. • Furnaces installed in hobby or craft rooms. • Furnaces installed near chemical storage areas. • Permanent wave solutions for hair. • Chlorinated waxes and cleaners. • Chlorine based swimming pool chemicals. • Water softening chemicals. • De-icing salts or chemicals. • Carbon tetrachloride. • Halo_erants. 441 01 2613 02 NOTE: Unused open vent hole must be covered. A Vent Cover is supplied with Vent Pipe Shield Kit NAHAOO2VC. A 55/16" diameter Vent Cover is available separately from your distributor, or one can be fabricated with sheet metal for all side vent installations. • Cleaning solvents (such as perchl...
