CARBON MONOXIDE POISONING HAZARD Failure to follow the steps outlined below for each appliance connected to the venting system being placed into operation could result in carbon monoxide poisoning or death. The following steps shall be followed for each appliance connected to the venting system being placed into operation, while all other appliances connected to the venting system are not in operation: 1. Seal any unused openings in venting system. 2.
NOTE: See the NFGC, 13.1.9 and 13.2.20 regarding alternative venting design and the exception, which cover installations such as the Chimney Adapter Kits KGACA02014FC and KGACA02015FC, which are listed for use with these furnaces. Table B—Minimum Allowable Input Rating of Space-Heating Appliance in Thousands of BTU per Hour The Chimney Adapter Kit is listed alternative venting design for these furnaces. See the kit instructions for complete details.
NOTE: Vent connector length for connector sizing starts at furnace vent elbow. The 4 inch vent elbow is shipped for upflow configuration and may be rotated for other positions. Remove the 3 screws that secure vent elbow to furnace, rotate furnace vent elbow to position desired, re-install screws. The factory-supplied vent elbow does NOT count as part of the number of vent connector elbows.
CHIMNEY INSPECTION CHART For additional requirements refer to the National Fuel Gas Code NFPA 54/ANSI Z223.1 and ANSI/NFPA 211 Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances in the U.S.A. or to the Canadian installation Codes CSA-B149.1 in Canada. Crown condition: Missing mortar or brick? Rebuild crown. Yes No Is chimney property lined with clay tile liner? No Yes Is liner and top seal in good condition? No Repair liner or top seal or reline chimney as necessary.
6. Verify furnace restarts by raising thermostat setting above room temperature. Personal injury can result form sharp metal edges, etc. Be careful when removing parts. Gloves and safety glasses should be worn when servicing equipment. Step 3—Adjustments 1. Maintain 115-v wiring and ground. Improper polarity will result in rapid flashing LED and no furnace operation. DO NOT bottom out gas valve regulator adjusting screw.

Step 5—Checklist The control system also requires an earth ground for proper operation of the control and flame-sensing electrode. 1. Put away tools and instruments. Clean up debris. The 24-v circuit contains an automotive-type, 3-amp fuse located on the control. (See Fig. 23.) Any shorts of the 24-v wiring during installation, service, or maintenance will cause this fuse to blow. If fuse replacement is required, use ONLY a 3-amp fuse.
SERVICE If status code recall is needed, briefly remove then reconnect one main limit wire to display stored status code. On RED LED boards do not remove power or blower door before initiating status code recall. After status code recall is completed component test will occur. LED CODE STATUS CONTINUOUS OFF - Check for 115VAC at L1 and L2, and 24VAC at SEC-1 and SEC-2. CONTINUOUS ON - Control has 24VAC power. RAPID FLASHING - Line voltage (115VAC) polarity reversed.
3. Check electrical connections for tightness and controls for proper operation each heating season. Service as necessary. 4. Inspect burner compartment before each heating season for rust, corrosion, soot or excessive dust. If necessary, have furnace and burner serviced by a qualified professional. BLOWER MOTOR AND WHEEL → 5. Inspect the vent pipe/vent system before each heating season for rust, corrosion, water leakage, sagging pipes or broken fittings.
e. Remove blower wheel from housing. CLEANING HEAT EXCHANGER f. Clean wheel and housing. The following steps should be performed by a qualified service technician: 12. Reassemble motor and blower by reversing steps 11f, finishing with 11a. Be sure to reattach ground wire to the blower housing. NOTE: If the heat exchangers get a heavy accumulation of soot and carbon, they should be replaced rather than trying to clean them thoroughly.

circuit starts the outdoor unit, and the R-to-G and Y circuits start the furnace blower motor BLWM on COOL speed. The electronic air cleaner terminal EAC-1 is energized with 115 vac when the blower motor BLWM is operating. When the thermostat is satisfied, the R-to-G-and-Y circuits are opened. The outdoor unit will stop, and the furnace blower motor BLWM will continue operating on the COOL speed for an additional 90 seconds. Cut jumper J2 to reduce the cooling off-delay to 5 seconds.
