recognized procedures identified by the Air Conditioning Con-  
tractors of America.  
These units are adaptable to downflow use as well as rear sup-  
ply and return air duct openings. To convert to downflow, use  
the following steps:  
LOCATION  
Use the following guidelines to select a suitable location for  
these units.  
1. Remove the duct covers found in the bottom return and  
supply air duct openings. There are four (4) screws secur-  
ing each duct cover (save these screws to use later).  
1. Unit is designed for outdoor installation only.  
2. Install the duct covers, removed in step one, to the rear  
supply and return air duct openings. Secure with the four  
(4) screws used in step one.  
2. Condenser must have an unlimited supply of air. Where a  
choice of location is possible, position unit on either north or  
east side of building.  
3. Seal the duct covers with silicone caulk.  
WARNING:Excessive exposure of this furnace to contami-  
nated combustion air may result equipment dam-  
age or personal injury. Typical contaminates  
include: permanent wave solutions, chlorinated  
waxes and cleaners, chlorine based swimming  
pool chemicals, water softening chemicals, carbon  
tetrachloride, Halogen type refrigerants, cleaning  
solvents (e.g. perchloroethylene), printing inks,  
paint removers, varnishes, hydrochloric acid, ce-  
ments and glues, antistatic fabric softeners for  
clothes dryers, masonry acid washing materials.  
Duct work should be designed and sized according to the  
methods of the Air Conditioning Contractors of America  
(ACCA), as set forth in their Manual D.  
A closed return duct system shall be used. This shall not pre-  
clude use of economizers or ventilation air intake. Flexible  
joints may be used in the supply and return duct work to mini-  
mize the transmission of noise.  
CAUTION: When fastening duct work to the side duct flanges on  
the unit, insert the screws through the duct flanges only.  
DO NOT insert the screws through the casing. Outdoor  
duct work must be insulated and waterproofed.  
3. For ground level installation, a level pad or slab should be  
used. The thickness and size of the pad or slab used should  
meet local codes and unit weight. Do not tie the slab to the  
building foundation.  
NOTE: Be sure to note supply and return openings.  
4. For roof top installation, be sure the structure will support  
the weight of the unit plus any field installed components.  
Unit must be installed on a level roof curb or appropriate an-

Refer to Figure 5 for information concerning rear and bottom  
supply and return air duct openings.  
Refer to Figure 5 for location of these access panels and mini-  
mum clearances.  
THERMOSTAT  
ROOF CURB  
The room thermostat should be located on an inside wall ap-  
proximately 56" above the floor where it will not be subject to  
drafts, sun exposure or heat from electrical fixtures or appli-  
ances. Follow manufacturer's instructions enclosed with the  
thermostat for general installation procedure. Four color coded  
insulated wires (minimum #18 AWG) should be used to con-  
nect thermostat to unit. See Figure 1.  
On applications when a roof curb is used, the unit must be posi-  
tioned on the curb so the front of the unit is tight against the  
curb.  
FILTERS  
Single phase units are shipped without a filter and is the responsi-  
bility of the installer to secure a filter in the return air ductwork or  
install a Filter/Frame Kit (1FF0110 for the D1NA018 thru  
D1NA042 and 1FF0112 for the D1NA048 and D2NA060).  
POWER AND CONTROL WIRING  
Field wiring to the unit must conform to provisions of the current  
N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances.  
The unit must be electrically grounded in accordance with local  
codes or, in their absence, with the N.E.C./C.E.C. Voltage tol-  
erances which must be maintained at the compressor termi-  
nals during starting and running conditions are indicated on the  
unit Rating Plate and Table 8.  
A filter rack and filters are standard on three phase units.  
NOTE: Filters on the D1NA048 and D2NA060 units require  
the use of a " nut driver for removal.  
Filters must always be used and must be kept clean. When fil-  
ters become dirt laden, insufficient air will be delivered by the  
blower, decreasing your units efficiency and increasing operat-  
ing costs and wear-and-tear on the unit and controls.  
The wiring entering the cabinet must be provided with me-  
chanical strain relief.  
A fused disconnect switch should be field provided for the unit. If  
any of the wire supplied with the unit must be replaced, replace-  
ment wire must be of the type shown on the wiring diagram.  
Filters should be checked monthly especially since this unit is  
used for both heating and cooling.  
CONDENSATE DRAIN  
Electrical line must be sized properly to carry the load. Each  
unit must be wired with a separate branch circuit fed directly  
from the meter panel and properly fused.  
A condensate trap is recommended to be installed in the con-  
densate drain. The plumbing must conform to local codes. Use  
a sealing compound on male pipe threads. Install the conden-  
sate drain line ( “ NPTF) to spill into an open drain.  
Refer to Figure 1 for typical field wiring and to the appropriate unit  
wiring diagram for control circuit and power wiring information.

phase scroll compressor is experiencing:  
GAS PIPING  
Proper sizing of gas piping depends on the cubic feet per hour  
of gas flow required, specific gravity of the gas and the length of  
run. “National Fuel Gas Code” Z223.1 or CAN/CGA B149.1 or  
.2 should be followed in all cases unless superseded by local  
codesorgascompanyrequirements. RefertoTables4and5.  
Low amperage draw  
Similar discharge and suction pressures  
Increased noise level  
then the compressor is operating in reverse. To correct this  
condition, switch any two (2) line voltage leads at the contactor.  
Please note, single phase scroll compressor will start and run  
in one direction only. The reverse operation is not a concern.  
The heating value of the gas may differ with locality. The value  
should be checked with the local gas utility.  
COMBUSTION DISCHARGE  
NOTE: There may be a local gas utility requirement specifying  
a minimum diameter for gas piping. All units require a  
1/2 inch pipe connection at the gas valve.

FLUE VENT HOOD  
The flue vent hood with screen is not shipped attached. This hood  
must be installed to assure proper unit operation. The hood must  
be fastened to the outside of the side gas control/electrical com-  
partment with the screws provided in the bag attached to the in-  
side of the gas control/electrical compartment, see Figure 3.  
CAUTION: If flexible stainless steel tubing is allowed by the  
authority having jurisdiction, wrought iron or steel  
pipe must be installed at the gas valve and extend a  
minimumoftwo(2)inchesoutsideoftheunitcasing.  
WARNING:Natural gas may contain some propane. Propane,  
being an excellent solvent, will quickly dissolve  
white lead or most standard commercial com-  
pounds. Therefore, a special pipe dope must be  
applied when wrought iron or steel pipe is used.  
Shellac base compounds such as Gaskolac or Sta-  
lastic, and compounds such as Rectorseal #5,  
Clyde's or John Crane may be used.

SEQUENCE OF OPERATION  
switches must be manually reset). The circulating fan remains  
energized for the selected heat delay off timing.  
HEATING  
Normal operation of the system resumes.  
When the thermostat calls for “HEAT”, the thermostat terminal  
“W” is energized, energizing the combustion air blower.  
COOLING  
After airflow is established, the air proving switch closes, the  
hot surface ignitor is energized and the pilot valve opens ignit-  
ing the pilot flame. The system will try to light the pilot for 90  
seconds. After 90 seconds, the pilot valve will close and the  
system will retry in 5 minutes.  
When the thermostat calls for “COOL”, the thermostat termi-  
nals “G” and “Y” are energized signaling the compressor and  
outdoor fan to run.  
After a cool fan on delay timing of 2 seconds, the circulating fan  
is energized at cooling speed.  
The flame rod senses a flame and de-energizes the ignitor  
opening the main gas valve and the main burners light.  
When the thermostat is satisfied, terminals “G” and “Y” are de-  
energized, de-energizing the compressor and outdoor fan.  
30 seconds after the main burners light the circulating fan is en-  
ergized at the heating speed.  
After a cool fan off delay timing of 30 seconds the circulating  
fan is de-energized.  
When the thermostat is satisfied, terminal “W” is de-energized,  
de-energizing the ignition system closing the gas valve.  
CIRCULATING FAN  
After a 5 second postpurge timing period, the combustion air  
blower is de-energized and the heat fan off timing begins.  
When the thermostat calls for “FAN”, the thermostat terminal  
“G” is energized signaling the circulating fan to run at the heat  
speed 2 seconds after the “G” terminal is energized.  
When this field selected heat fan off timing is completed the cir-  
culating fan is de-energized.  
If a call for “HEAT” occurs, the circulating fan continues to run at  
the heat speed.  
If the primary, rollout or auxiliary limit switches open, the ther-  
mostat and ignition system is de-energized and the gas valve  
closes. The combustion blower and the circulating fan, at heat  
speed, are energized.  
If a call for “COOL” occurs, the circulating fan switches to cool  
speed after a 4 second delay.  
When the thermostat ends the call for “FAN”, the thermostat  
terminalGisde-energized, de-energizingthecirculatingfan.  
The combustion blower remains energized for the 5 second  
postpurge timing period if the primary, rollout or auxiliary limit  
switches remake the contact (the rollout and auxiliary limit

ADJUSTMENT OF TEMPERATURE RISE  
BTUH Output  
1.08 x CFM  
BTUH Output  
(OR) CFM =  
°F Temp. Rise =  
1.08 x °F Temp. Rise  
The temperature rise (or temperature difference between the  
return air and the heated air from the furnace) must lie within  
the range shown on the rating plate and the data in Tables 2  
and 3.  
After the temperature rise has been determined, the CFM can  
be calculated as follows:  
After about 20 minutes of operation, determine the furnace  
temperature rise. Take readings of both the return air and the  
heated air in the ducts about six feet from the furnace where  
they will not be affected by radiant heat. Increase the blower  
CFM to decrease the temperature rise; decrease the blower  
CFM to increase the rise.  
DIRECT DRIVE BLOWER  
All units have direct drive multi-speed blower motors. Refer to  
the unit wiring diagram and connect the blower motor for the  
desired CFM.

CHECKING GAS INPUT  
Example: By actual measurement, it takes 38 seconds for the hand on the 1-cubic foot dial to  
make a revolution with just a 100,000 BTUH furnace running. Using this information, locate 38  
seconds in the first column of Table 9. Read across to the column headed “1 Cubic Foot,”  
where you will see that 95 cubic feet of gas per hour are consumed by the furnace at that rate.  
Multiply 95 x 1050 (the BTU rating of the gas obtained from the local gas company). The result  
is 99,750 BTUH, which is close to the100,000 BTUH rating of the furnace.  
NATURAL GAS  
1. Turnoffallothergasappliancesconnectedtothegasmeter.  
2. With the furnace turned on, measure the time needed for one  
revolution of the hand on the smallest dial on the meter. Atypi-  
cal gas meter usually has a 1/2 or a 1 cubic foot test dial.  
3. Using the number of seconds for each revolution and the  
size of the test dial increment, find the cubic feet of gas con-  
sumed per hour from Table 9.  
If the actual input is not within 5% of the furnace rating with al-  
lowance being made for the permissible range of the regulator  
setting, replacetheorificespudswithspudsofthepropersize.  
NOTE: Tofind the BTU input, multiply the number of cubic feet of  
gas consumed per hour by the BTU content of the gas in  
your particular locality. (Contact your gas company for  
this information since it varies widely from city to city.)  
SECURE OWNER'S APPROVAL  
When the system is functioning properly, secure the owner's ap-  
proval. Show him the location of all disconnect switches and the  
thermostat. Teach him how to start and stop the unit and how to  
adjust temperature settings within the limitations of the system.  
Advise him that the flue exhaust hood surface and the immediate  
area will experience high temperatures during the heating cycle.  
All unauthorized personnel and debris must be kept away from  
this area.

MAINTENANCE  
TO CLEAN BURNERS - Remove them from the furnace as ex-  
plained in “Burner Instructions”. Clean burners with hot water  
applied along top of the burner.  
NORMAL MAINTENANCE  
WARNING:Prior to any of the following maintenance proce-  
dures, shut off all power to the unit, to avoid per-  
sonal injury.  
COMBUSTION AIR DISCHARGE - Visually inspect discharge  
outlet periodically to insure soot and dirt buildup is not exces-  
sive. If necessary, clean to maintain adequate combustion air  
discharge.  
Periodic maintenance consists of changing or cleaning filters.  
Under some conditions, the main burners should be cleaned.  
FILTERS - Inspect once a month. Replace Disposable or clean  
Permanent Type as necessary. DO NOT replace Permanent  
Type with Disposable.  
The manufacture recommends that the furnace system be in-  
spected once a year by a qualified service person.  
CLEANING FLUE PASSAGES AND HEATING ELEMENTS  
MOTORS - Indoor and outdoor fan motors, along with the com-  
bustion blower are permanently lubricated and require no  
maintenance.  
With proper combustion adjustment the heating element of a  
gas fired furnace will seldom need cleaning. If the element  
should become sooted, it can be cleaned as follows:  
OUTDOOR COIL- Dirt should not be allowed to accumulate on  
the outdoor coil surface or other parts in the air circuit. Cleaning  
should be as often as necessary to keep the coil clean. Use a  
brush, vacuum cleaner attachment, or other suitable means. If  
water is used to clean the coil, be sure that the power to the unit  
is shut off prior to cleaning.  
1. Remove the burner assembly as outlined in “BURNER IN-  
STRUCTIONS”.  
2. Remove the screws securing the restrictor plate to the tube  
sheet.  
3. Using a wire brush on a flexible wand, brush out the inside  
of each heat exchanger from the burner inlet and flue outlet  
ends.  
CAUTION: Exercise care when cleaning the coil so that the  
coil fins are not damaged.  
4. Brushouttheinsideoftherestrictorplatetothetubesheet.  
Do not permit the hot condenser air discharge to be  
obstructed by overhanging structures or shrubs.  
5. If soot build-up is particularly bad, remove the vent motor  
and clean the wheel and housing.  
6. After brushing is complete, blow all brushed areas with air

BURNER - At the beginning of each heating season, make a  
visual check of the main burner flame. If it is not possible to ad-  
just for the proper flame, the burners may need cleaning.  
7. Replace parts in the order they were removed in steps 1

Checking Supply Air CFM  
a dry coil, the compressors should be deactivated while the test  
is being run.  
To check the supply air CFM after the initial balancing has been  
completed:  
4.Knowing the pressure drop across a dry coil, the actual CFM  
through the unit can be determined from the curve in Coil Delta  
P vs. Supply Air CFM figure.  
1.Remove the two ¼ inch dot plugs in the duct panel.  
2.Insert at least 8 inches of ¼ inch tubing into each of these  
holes for sufficient penetration into the airflow on both sides of  
the indoor coil.  
WARNING! Failure to properly adjust the total system air quan-  
tity can result in extensive system damage.  
After readings have been obtained, remove the tubes and rein-  
stall the two ¼ inch plugs removed in Step 1.  
3.Using an inclined manometer, determine the pressure drop  
across the dry evaporator coil. Since the moisture on an evapo-  
rator coil may vary greatly, measuring the pressure drop across  
a wet coil under field conditions would be inaccurate. To ensure  
NOTE: De-energize the compressors before taking any test  
measurements to ensure a dry indoor coil.
