hoisting.
The unit should be hoisted with two lifting slings. Attach the
slings to rigging shackles that have been hooked through
holes in the base rail.
Two spreader bars MUST be placed on top of the unit to
protect the unit from damage from the pressure exerted by
the slings. Make sure that all equipment is adequate to
handle the weight of the unit and that the slings will not allow
the unit to shift.
Refer to FIGURE 17 on the back cover of this manual for
illustrated rigging instructions and weight chart.
DOWNFLOW CONVERSION
NOTE: In downflow applications with roof curbs or jack
stands, the center rail under the unit must be removed. The
center rail is attached to the base rail with screws.
These units are adaptable to downflow use. To convert to
downflow use, follow these steps:
1. Remove the blockoff plates found in the return air
compartment and the supply air compartment.
NOTE: Blockoff plate in the supply air compartment only
contains one screw. If reinstalling plate, back part of plate
MUST fit into mating dimples on flange. To reinstall, slant
plate into dimples, then put plate into position and fasten
with screw.
2. Install the removed plates on the horizontal return and

SEMBLY INSTALLED
Condensate Drain
The condensate drain outlet is a 3/4" (19.1 mm) female PVC
connection located at the bottom on the left hand side (see
FIGURE 3).
The circulating blower creates a negative pressure on the
condensate drain line that can prevent the condensate from
draining properly. To combat this negative pressure, a field
supplied condensate trap that will allow a standing column
of water of at least 2" (50.8mm) MUST be installed. Top of
outlet from trap MUST be at least 1" (25.4mm) below top of
outlet from unit. Install the trap as near to the unit as
possible for proper drainage,
A3/4" (19.1mm) drain line MUST be installed if required by
local codes or if location of unit requires it. Run the drain line
to an open drain or other suitable disposal point.

CIRCULATING AIR BLOWER
Check the unit's operation as outlined in the following
instructions, tf any unusual sparking, odors or unusual
noises are encountered, shut off electric power
immediately. Recheck for wiring errors, or obstructions in or
near blower motors.
1. Set thermostat Heat-Cool selector to OFE
2. Set thermostat fan switch to AUTO.
3. Turn electric power ON. Nothing should start running.
4. Turn manual gas valve ON.
5. Turn gas control valve ON.
6. Set thermostat fan switch to ON.
7. Reset thermostat fan switch to AUTO.
HEATING START-UP PROCEDURE
1. Adjust thermostat setting above room temperature and
set thermostat selector to HEAT. The combustion air
blower should come ON.
2. The ignitor should begin to glow and pilot flame should
light. Refer to Lighting/Operating Instructions label lo-
cated on Burner Access Panel of unit.
NOTE: On a call for heat the ignitor and pilot valve will
remain energized until a flame is detected by the flame
sensor. It may take several minutes to purge the air out of
the gas lines at initial start-up of the unit.
3. Once the flame sensor detects that a flame is present,
the hot surface ignitor will de-energize and the main
burners will light from the pilot.
4.30 seconds after the burners light, the circulating blow-
er should begin to run.
Fire and/or explosion hazard.
Do NOT attempt to light the pilot or burner with a match or
flame of any kind.
Failure to follow this warning can result in property damage,
personal injury, and/or death.
Temperature Rise Check
NOTE: Air temperature rise is the temperature difference
between supply and return air. With a properly designed
distribution system, the proper amount of temperature rise
will normally be obtained when the unit is operating at rated
input with the recommended blower speed.
1. The temperature rise must be within the specifications
marked on the unit rating plate.
To check the temperature rise through the unit, place ther-
mometers in the supply and return air ducts as close to the
unit as possible.
Open ALL registers and duct dampers. Operate unit AT
LEAST 15 minutes before taking readings,
If the correct amount of temperature rise is not obtained
when operating on the recommended blower speed, it may
be necessary to change the blower speed. A faster blower
speed will decrease the temperature rise. A slower blower
speed will increase the temperature rise.
NOTE: The blower speed MUST be set to give the correct
air temperature rise through the furnace as marked on the
rating plate. See FIGURE 13 for more information.
2. After 15 minutes of operation check the limit control
function by blocking the
return air grille(s).
After several minutes the main burners and pilot should
go OFF. The circulating air blower should continue to
run.
Remove air restrictions. Pilot and main burners should
relight after a cool down period of a few minutes.
3. Adjust the thermostat setting below room temperature.
Pilot and main burners and combustion air blower
should go OFF.
The circulating air blower should continue to run for 60,
100, 14-0or 180 seconds. This time is adjustable. See
FIGURE 12 for more information.
4. Set thermostat Heat-Cool selector to OFF.

sired comfort level,
SPEED TAPS
After determining necessary CFM and speed tap data,
follow the steps below to change speeds.
1, Refer to FIGURE 13 and locate the speed tap block on
blower motor.
2. The yellow lead MUST always be connected to the
speed tap block at the common quick connect terminal.
The terminal is identified as COM. Also, this is the only
lead which is 3/16" wide, All other quick connects are
1/4"wide.
3, If it has been determined that cooling and heating
speeds are needed on the same speed tap, remove the
red heating lead from the speed tap block and connect it
to the insulated male terminal on the black cooling lead.
Then place the insulated black female quick connect to
the required speed tap,
180
Seconds
CONTINUOUS FAN OPERATION
An optional terminal may be provided on the electronic fan
control located in the electrical control box area for
operation of the continuous fan option. This connection is
intended for the low speed motor tap, and has a lower
contact rating (8 amps) than the heat and cool taps. When
the low speed blower lead is connected to this terminal, this
will provide low speed blower operation whenever the other
two speeds (Heat or Cool) are not energized.
Thoroughly check the system after modification to ensure
the proper operation of the circulating air blower in all
modes of operation.
Separate Speed Selections for Heat, Cool and
Continuous Fan
Connect low speed lead from circulating motor to the
"Cont" terminal at the electronic fan control. The
appropriate motor leads should already be connected to the
"Heat" and "coor' terminals.
Note: See next section "Heating or Cooling and
Continuous Blower Speed the Same" if low speed is
required for heating to obtain desired temperature rise,
Heating or Cooling and Continuous Blower Speed
the Same
If is is necessary to operate the heating or cooling speed
and continuous blower speed using the same blower
speed, connect a jumper between the "Heat" and "Cont"
terminals on the Fan Timer Board,
Note: There should be only ONE motor lead going to the
"Heat" and "Cont" terminals,

Failure to follow this warning can result in property damage,
personal injury, and/or death.
COMBUSTION/INDOOR FAN CONTROL
All functions of the combustion and indoor blower are
controlled by the fan control module.
On a call for heat:
The fan control energizes the combustion blower. Once the
combustion air proving switch closes, the ignition sequence
begins. The fan control will sense when the main operator
of gas valve has been energized thereby firing the burners
and starting the "delay on" timing sequence of the indoor
blower.
NOTE: Ifthe control senses that one of the safety limits has
opened, the combustion and indoor fans will operate until
the limit resets.
On a call for cooling:
The fan control starts the indoor blower at 0 or 30 seconds.
f
Once the thermostat is satisfied, the fan control will operate
the blower for 30 additional seconds.
