SERVICE AND TECHNICAL SUPPORT MANUAL Gas Furnace: (F/G)9MVESpecifications subject to change without notice.440 04 4801 00 5Prime Condensate Trap with Water! WARNINGCARBON MONOXIDE POISONING HAZARDFailure to follow these warnings could result in personal injuryor death.Failure to use a properly configured trap or NOTwater-priming trap before operating furnace may allowpositive pressure vent gases to enter the structure throughdrain tube. Vent gases contain carbon monoxide which istasteless and odorless.UNIT OPERATION HAZARDFailure to follow this caution may result in intermittent unitoperation or performance satisfaction.Condensate trap must be PRIMED or proper draining maynot occur. The condensate trap has two internal chamberswhich can ONLY be primed by pouring water into theinducer drain side of condensate trap.CAUTION!1. Remove upper and middle collector box drain plugsopposite of the condensate trap. (See Figure 1)2. Connect field-supplied 5/8-in. (16 mm) ID tube withattached funnel (see Figure 1) to upper collector boxdrain connection.3. Pour one quart (liter) of water into funnel/tube. Watershould run through collector box, overfill condensatetrap, and flow into open field drain.4. Remove funnel; replace collector box drain plug.5. Connect field-supplied 5/8-in. (16 mm) ID tube to middlecollector box drain port.6. Pour one quart (liter) of water into funnel/tube. Watershould run through collector box, overfill condensatetrap, and flow into open field drain.7. Remove funnel and tube from collector box and replacecollector box drain plug.Figure 1 Priming Condensate DrainL11F065Representative drawing only, some models may vary in appearance.Purge Gas LinesIf not previously done, purge the lines after all connectionshave been made and check for leaks.FIRE OR EXPLOSION HAZARDFailure to follow this warning could result in personal injury,death, and/or property damage.Never purge a gas line into a combustion chamber. Nevertest for gas leaks with an open flame. Use a commerciallyavailable soap solution made specifically for the detectionof leaks to check all connections. A fire or explosion mayresult causing property damage, personal injury or loss oflife.! WARNINGAdjustmentsFIRE HAZARDFailure to follow this warning could result in personal injury,death and/or property damage.DO NOT bottom out gas valve regulator adjusting screw.This can result in unregulated manifold pressure and resultin excess overfire and heat exchanger failures.! WARNINGFURNACE DAMAGE HAZARDFailure to follow this caution may result in reduced furnacelife.DO NOT redrill orifices. Improper drilling (burrs,out−of−round holes, etc.) can cause excessive burner noiseand misdirection of burner flames. This can result in flameimpingement of heat exchangers, causing failures. (SeeFigure 2)CAUTION!Figure 2 Orifice HoleA93059BURNERORIFICEFor proper operation and long term reliability the furnace inputrate must be within +/− 2 percent of input rate on furnace ratingplate, or as adjusted for altitude.
