SAFETY CONSIDERATIONS Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified personnel should install, repair, or service heating equipment. Untrained personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations must be performed by trained service personnel.

6. Before removing a new control from its container, discharge your body’s electrostatic charge to ground to protect the control from damage. If the control is to be installed in a furnace, follow items 1 through 5 before bringing the control or yourself into contact with the furnace. Put all used AND new controls into containers before touching ungrounded objects. These instructions cover minimum requirements for a safe installation and conform to existing national standards and safety codes.

III. DOWNFLOW APPLICATIONS (1.) Condensate Trap Located on Left Side of Casing A downflow furnace application is where furnace blower is located above combustion and controls section of furnace, and conditioned air is discharged downwards. (a.) Connect LOWER collector box drain tube (blue and white striped label) to condensate trap. Tube does not need to be cut. A. (b.) Clamp tube to prevent any condensate leakage.
PAGE 8
NOTE: See Fig. 7 or 8 or tube routing label on main furnace door to check for proper connections. d. Use inducer housing drain tube (violet label and factorysupplied in loose parts bag) to connect LOWER inducer housing drain connection to the condensate trap. Relocate tubes as described below. e. Connect inducer housing drain connection to condensate trap. 1. Disconnect collector box pressure tube (pink label) attached to pressure switch. (1.) Condensate Trap Located on Left Side of Casing 2.

C. CAUTION: Local codes may require a drain pan under entire furnace and condensate trap when a condensing furnace is used in an attic application or over a finished ceiling. → D. Pressure Switch Tubing The LOWER collector box pressure tube (pink label) is factory connected to the pressure switch for use when furnace is installed in UPFLOW applications. This tube MUST be disconnected, extended, rerouted, and then reconnected to the pressure switch in HORIZONTAL LEFT applications. NOTE: See Fig.

WARNING: Do not bend duct flanges inward as shown in Fig. 15. This will affect airflow across heat exchangers and may cause limited cycling or premature heat exchanger failure. Remove duct flange completely or bend it inward a minimum of 210° as shown in Fig. 15. FURNACE (OR COIL CASING WHEN USED) 2. When complete, downflow subbase, plenum, and furnace (or coil casing when used) should be installed as shown in Fig. 16. IV.

V. FILTER ARRANGEMENT 171⁄2-IN. WIDE CASINGS ONLY: INSTALL FIELD-SUPPLIED FILTER FILLER STRIP UNDER FILTER. CAUTION: Never operate unit without a filter or with blower access panel removed. Factory-supplied washable framed filters are shipped in blower compartment. Determine location for filter and relocate filter retaining wire if necessary. See Table 1 to determine correct filter size for desired filter location. Table 1 indicates filter size, location, and quantity shipped with this furnace. See Fig.
PAGE 16
VII. GAS PIPING GAS SUPPLY Gas piping must be installed in accordance with national and local codes. Refer to current edition of NFGC. Canadian installations must be made in accordance with NSCNGPIC and all authorities having jurisdiction. Gas supply line should be a separate line running directly from meter to furnace, if possible. Refer to Table 2 for recommended gas pipe sizing. Risers must be used to connect to furnace and to meter. Support all gas piping with appropriate straps, hangers, etc.

4. The 3-in. concentric vent/air termination kit is for 2-1/2 in. and 3-in. diameter pipe systems when single penetration of wall or roof is desired. NOTE: Shaded parts in Fig. 30, 31, 32, 33, and 34 are considered to be termination. These components should NOT be counted when determining pipe diameter. Roof termination is preferred since it is less susceptible to damage, has reduced chances to intake contaminants, and has less visible vent vapors. (See Fig. 30 or 31.

1. Prepurge period—As inducer motor comes up to speed, pressure switch contacts close to begin a 15-sec prepurge period. 2. Ignitor warm up—At end of prepurge period, ignitor is energized for a 17-sec ignitor warm-up period. 3. Ignition sequence—When ignitor warm-up period is completed, gas valve opens, permitting gas flow to burners where it is ignited. After 5 sec, ignitor is de-energized and a 2-sec flame-sensing period begins.
