5 Adhere to the following warnings and cautions when installing, adjusting, altering, servicing, or operating the furnace. T o e nsure proper installation and operation, thoroughly read this manual for specifics pertaining to the installation and application of this product.
6 S HIPPING I NSPECTION All units are securely packed in shipping containers tested ac- cording to International Safe T ransit Association specifications. The carton must be checked upon arrival for external damage. If damage is found, a request for inspection by carrier’s agent must be made in writing immediately .

9 • If the furnace is used in connection with a cooling coil unit, install the furnace upstream or in parallel with the cooling coil unit. Premature heat exchanger failure will result if the cooling unit is placed ahead of the furnace.
10 • Concealed hot or cold water pipes, or chimneys. • Unconditioned areas behind the thermostat, such as an outside wall. Consult the instructions packaged with the thermostat for mounting instructions and further precautions.
11 H ORIZONT AL A PPLICA TIONS & C ONSIDERA TIONS Horizontal applications, in particular , may dictate many of the installation’s specifics such as airflow direction, ductwork connec- tions, flue and combustion air pipe connections, etc.
12 A LTERNATE E LECTRICAL AND G AS L INE C ONNECTIONS This furnace has provisions allowing for electrical and gas line con- nections through either side panel. In horizontal applications the connections can be made either through the “top” or “bottom” of the furnace.

14 vicing. Combustion Air and V ent piping should be routed in a man- ner to avoid contact with refrigerant lines, metering devices, con- densate drain lines, etc. If necessary , clearances may be in- creased by utilizing two 45 deg. Long-Sweep Elbows and creat- ing an “S” joint to provide additional space at connection loca- tions.

16 8. Upflow and Counterflow units . For horizontal installations , externally secure the field- supplied vent/flue pipe directly to the vent/flue coupling using a PVC or ABS coupling or elbow .
17 N ON -D IRECT V ENT (S INGLE P IPE ) P IPING Non-direct vent installations require only a vent/flue pipe. The vent pipe can be run horizontally with an exit through the side of the building or run vertically with an exit through the roof of the building.
18 V ENT /F LUE P IPE T ERMINATIONS The vent/flue pipe may terminate vertically , as through a roof, or horizontally , as through an outside wall. V ertical vent/flue pipe terminations should be as shown in the fol- lowing figure. Refer to Vent/Flue Pipe and Combustion Air Pipe - T ermination Locations for details concerning location restrictions.
19 If the combustion air intake pipe is to be installed above a finished ceiling or other area where dripping of condensate will be objec- tionable, insulation of the combustion air pipe may be required. Use 1/2” thick closed cell foam insulation such as Armaflex™ or Insultube™ where required.

21 C ONDENSA TE D RAIN L INES & D RAIN T RAP A condensing gas furnace achieves its high level of efficiency by extracting almost all of the heat from the products of combustion and cooling them to the point where condensation takes place. The condensate which is generated must be piped to an appropri- ate drain location.
22 U PRIGHT I NSTALLATIONS -T RAP ON R IGHT S IDE In a upright installation drain hoses are connected to drain ports on the rubber elbow and the recuperator coil front cover . The drain lines are then routed through the right side panel and into the drain trap secured to the outside of the cabinet.
23 A LTERNATE V ENT /F LUE D RAIN H OSE C ONNECTIONS Upright installations using the alternate vent/flue outlet will require “right-side only” drain hoses to be connected as follows. Refer to Vent/Flue Pipe and Combustion Air Pipe for details on alternate vent/flue pipe connection .
24 U PRIGHT I NSTALLATIONS -T RAP ON L EFT S IDE NOTE: For left side trap installation, grommets must be moved to the left side of the furnace and the plugs installed on the right side of the furnace. 1. Remove the rubber plug/cap from the left side drain port on the front cover .
25 U PRIGHT D RAIN T RAP M OUNTING (L EFT OR R IGHT S IDE P ANEL ) 1. Insert drain tubes into drain trap and position the drain trap against the side panel.
26 L EFT S IDE D OWN Horizontal installations with the left side panel down will require drain hoses to be connected to the left side front cover drain port and the side drain port on the rubber elbow . 1 . Remove the rubber plug/cap from the front cover left (down) side drain port.

28 1 . Measure resistance between the neutral (white) connection and one of the burners. 2. Resistance should measure 10 ohms or less. This furnace is equipped with a blower door interlock switch which interrupts unit voltage when the blower door is opened for servicing.
29 T o use a single-stage thermost at, turn of f power to the furnace, move the thermostat selection DIP switch to the OFF position. Set the desired transition time by setting the transition delay DIP switch to the desired ON/OFF position. Turn power back on.
30 Accessories Wiring If it is necessary for the installer to supply additional line voltage wiring to the inside of the furnace, the wiring must conform to all local codes, and have a minimum temperature rating of 105°C. All line voltage wire splices must be made inside the furnace junction box.
31 Consult the furnace S pecification Sheet for a listing of appropri- ate kits. The indicated kits must be used to insure safe and proper furnace operation.

37 H EAT A NTICIPATOR S ETTING The heat anticipator in the room thermostat must be correctly adjusted to obtain the proper number of cycles per hour and to prevent “overshooting” of the setting. Set the heat anticipator set- ting to 0.7 amps. Follow the thermostat manufacturer’s instruc- tions on how to adjust the heat anticipator setting.

48 • Integrated control module performs safety circuit checks. • Induced draft blower is energized on high speed for a 15- second prepurge. Humidifier terminal is energized with induced draft blower . • Induced draft blower steps to low speed following prepurge.
49 O PERA TIONAL C HECKS The burner flames should be inspected with the burner compart- ment door installed. Flames should be stable, quiet, soft, and blue (dust may cause orange tips but they must not be yellow). Flames should extend directly outward from the burners without curling, floating, or lifting off.
50 R ESETTING F ROM L OCKOUT Furnace lockout results when a furnace is unable to achieve igni- tion after three attempts during a single call for heat. It is charac- terized by a non-functioning furnace and a E E E E E 0 0 0 0 0 code displayed on the dual 7-segment display .
51 C ONDENSATE T RAP AND D RAIN S YSTEM (Q UALIFIED S ERVICER O NLY ) Annually inspect the drain tubes, drain trap, and field-supplied drain line for proper condensate drainage. Check drain system for hose connection tightness, blockage, and leaks. Clean or repair as necessary .
