6 • It must be installed indoors in a building constructed on site. • It must be part of a ducted system and not used in a free air delivery application. • It must not be used as a “make-up” air unit. • All other warranty exclusions and restrictions apply .
7 T o ensure proper furnace operation, inst all, operate and maintain the furnace in accordance with these installa- tion and operation instructions, all local building codes and ordinances. In their absence, follow the latest edition of the National Fuel Gas Code (NFP A 54/ANSI Z223.

9 a residential garage must be installed so that the ignition source and burners are located not less than eighteen inches (18") above the floor and is protected or located to prevent physical damage by vehicles. A gas furnace must not be installed di- rectly on carpeting, tile, or other combustible materials other than wood flooring.

11 8. Install the chimney top with the four screws retained from step 6 onto the new chimney transition bottom from the transition bottom kit. 9. Install chimney assembly with the three screws retained from step 5 onto the induced draft blower .
12 If the chimney does not meet these termination requirements, but all other requirements in the checklist can be met, it may be possible for a mason to extend the chimney . If this will not be practical, see Fix 1. W a ll o r Par a pe t 2' M in .
13 Next, use a flashlight and small mirror to sight up the liner . B vent must be supported so as to not come into direct contact with the chimney walls or tile liner . If it is not, it can probably be rehung so as to be acceptable. A thimble or fire stop may be helpful here.
14 F IX 3 - R EBUILD THE C ROWN If the chimney crown is damaged, a qualified mason must re- pair it in accordance with nationally recognized building codes or standards. One such standard which may be referenced is the S tandard for Chimneys, Fireplaces, V ent s, and Solid Fuel Burning Appliances, ANSI/NFP A 21 1.
15 For sizing of flexible liners, see Note 22 and the tables in the National Fuel Gas Code NFP A 54/ANSI Z223.1 - latest edition and in the National S tandard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments. T o inst all the liner , read and follow the liner manufacturer ’s in- structions and your local codes.

17 NOTE: Thermostat “R” required if outdoor unit is equipped with a Comfort Alert™ module or if the outdoor unit is a part of the ComfortNet™ family of equipment AND is wired as a non- communicating system.
18 5. Turn ON power to furnace. T o enable the dehumidify function on the integrated control mod- ule, set the dehumidification ENABLE dipswitch from OFF to ON. Once the switch is set, the dehumidify function is enabled dur- ing a combination call for cooling (T -S tat) and dehumidification (DEHUM-S tat).
19 24 V OLT H UMIDIFIER A 24 volt humidifier can be powered by feeding one of the HUM terminals with a field installed wire from the R terminal or by connecting to the NO side of the low fire pressure switch. G AS S UPPL Y AND P IPING The furnace rating plate includes the approved furnace gas in- put rating and gas types.
20 When sizing a trunk line, be sure to include all appliances which will operate simultaneously . The gas piping supplying the furnace must be properly sized based on the gas flow required, specific gravity of the gas, and length of the run.
21 C OUNTERFLOW I NSTALLATIONS When the gas piping enters through the left side of the furnace, the installer must supply a straight pipe and a 90 degree elbow to reach the exterior of the furnace. A ground joint union, drip leg and manual shutoff valve must also be supplied by the installer .

23 Example: static reading from return duct = -.1" w .c. static reading from supply duct = .3" w .c. total external static pressure on this system = .4" w .c. NOTE: Both readings may be taken simultaneously and read directly on the manometer if so desired.
24 NOTE: This furnace is equipped with an ignition device which automatically lights the burner . Do not try to light the burner by hand. 5. Move the furnace gas valve manual control to the OFF position. 6. Wait five minutes then smell for gas. Be sure check near the floor as some types of gas are heavier than air .
25 2. Connect a calibrated water manometer (or appropriate gas pressure gauge) at either the gas valve inlet pressure boss or the gas piping drip leg. See Honeywell VR9205 gas valve figure or White-Rodgers 36G54 gas valve figure for location of inlet pressure boss.
26 Using a leak detection solution or soap suds, check for leaks at outlet pressure boss plug (Honeywell valve) or screw (White- Rodgers valve). Bubbles forming indicate a leak. SHUT OFF GAS AND REP AIR ALL LEAKS IMMEDIA TEL Y! NOTE: For gas to gas conversion, consult your dealer for appropriate conversion.
27 shipped set at “B”, and the cooling blower speed is set at “D”. These blower speeds should be adjusted by the installer to match the installation requirements so as to provide the cor- rect heating temperature rise and correct cooling CFM.

29 tween the thermostat and subsystems (indoor/outdoor unit) and between subsystems is the key to unlocking the benefits and features of the ComfortNet system. T wo-way digital communications is accomplished using only two wires. The thermostat and subsystem controls are power with 24 V AC.

33 N ETWORK TROUBLESHOOTING Communications is achieved by taking the difference between two dc signals. The signals and transmission lines are re- ferred to as “data 1” and “data 2”. Each transmission line is biased to approximately 2.5Vdc. During data reception/trans- mission, the data lines vary between +5V and ground.
34 H EATING M ODE The normal operational sequence in heating mode is as fol- lows: • R and W1 (or R and W1/W2) thermostat contacts close, initiating a call for heat. • Integrated control module performs safety circuit checks. • Induced draft blower is energized on high speed for a 15- second prepurge.
35 • Gas valve opens at end of igniter warm up period, delivering gas to burners and establishing flame. • Integrated control module monitors flame presence. Gas valve will remain open only if flame is detected. • If the thermostat call is for low heat, gas valve and induced draft blower will continue on low stage.
36 Check the Burner F lames f or: 1. S table , so f t and blue. 2. N ot curling, floati ng or lift i ng off. Burner Flame S AFETY C IRCUIT D ESCRIPTION A number of safety circuits are employed to ensure safe and proper furnace operation.
37 F AULT R ECALL The ignition control is equipped with a momentary push-button switch that can be used to display the last six faults on the dual 7-segment LED’s. The control must be in S t andby Mode (no thermostat inputs) to use the feature. Depress the switch for approximately 2 seconds.
38 B URNERS Visually inspect the burner flames periodically during the heat- ing season. Turn on the furnace at the thermostat and allow several minutes for flames to stabilize, since any dislodged dust will alter the flames normal appearance. Flames should be stable, quiet, soft, and blue (dust may cause orange tips but they must not be yellow).
