NPTfitting which exits through the base on the evaporator coil accessside. See Fig. 3 & 4 for location.Condensate water can be drained directly onto the roof in rooftopinstallations (where permitted) or onto a gravel apron in groundlevel installations. Install a field--supplied 2--in. (50.8 mm)condensate trap at the end of condensate connection to ensureproper drainage. Make sure that the outlet of the trap is at least 1 in.(25.4 mm) lower than the drain--pan condensate connection toprevent the pan from overflowing (See Fig. 7). Prime the trap withwater. When using a gravel apron, make sure it slopes away from theunit.Connect a drain tube using a minimum of 3/4--in. PVC or 3/4--in.copper pipe (all field--supplied) at the outlet end of the 2--in. trap.Do not undersize the tube. Pitch the drain tube downward at a slopeof at least 1--in. for every 10 ft of horizontal run. Be sure to checkthe drain tube for leaks.TRAPOUTLET2" min.1" min.C00009Fig. 7 -- Condensate TrapStep 7—Install Flue HoodThe flue assembly is secured and shipped in the return air duct.Remove duct cover to locate the assembly (See Fig. 9 and 10).NOTE: Dedicated low NOx models MUST be installed inCalifornia Air Quality Management Districts where a Low NOxrule exists.These models meet the California maximum oxides of nitrogen(NOx) emissions requirements of 40 nanograms/joule or less asshipped from the factory.NOTE: Low NOx requirements apply only to natural gasinstallations.CARBON MONOXIDE POISONING HAZARDFailure to follow this warning could result in personal injuryor death.The venting system is designed to ensure proper venting. Theflue hood assembly must be installed as indicted in this sectionof the unit installation instructions.! WARNINGInstall the flue hood as follows:1. This installation must conform with local building codes andwith the National Fuel Gas Code (NFGC), ANSI Z223.1 (inCanada, CAN/CGA B149.1, and B149.2) or NFPA(National Fire Protection Association) latest revision.
