DESCRIPTION

These compact units employ induced combustion, reliable hot

surface ignition and high heat transfer aluminized steel tubular

heat exchangers. The units are factory shipped for installation

in upflow or horizontal applications and may be converted for

downflow applications.

These furnaces are designed for residential installation in a

basement, closet, alcove, attic, recreation room or garage and

are also ideal for commercial applications. All units are factory

assembled, wired and tested to assure safe dependable and

economical installation and operation.

These units are Category I listed and may be common vented

with another gas appliance as allowed by the National Fuel Gas

Code.

FEATURES

• Two stage heating operation includes two stage gas valve,

two stage inducer operation and standard ECM blower

operation. Auto-staging allows two stage operation with a

single stage thermostat.

HORIZONTAL SIDEWALL VENTING

For applications where vertical venting is not possible, the only

approved method of horizontal venting is the use of an auxiliary

power vent. Auxiliary power venter's must be approved by CSA,

UL, or other recognized safety agencies. Follow all application

and installation details provided by the manufacturer of the

power vent.

FILTER PERFORMANCE

The airflow capacity data published in the “Blower Perfor-

mance” table shown represents blower performance WITHOUT

filters.

All applications of these furnaces require the use of field

installed air filters. All filter media and mounting hardware or

provisions must be field installed external to the furnace cabi-

net. DO NOT attempt to install any filters inside the furnace. 1. Air velocity through throwaway type filters may not exceed 300 feet per min-

ute (91.4 m/min). All velocities over this require the use of high velocity fil-

ters.

2. Do not exceed 1800 CFM using a single side return and a 16x25 filter. For

CFM greater than 1800, you may use two side returns or one side and the

bottom or one return with a transition to allow use of a 20x25 filter.

nace cabinet.

Masonry Chimney Kits -

For installations where these furnaces are vented using existing

or new lined masonry chimneys.

1CK0603

1CK0604

Combustible Floor Base Kit -

For installation of these furnaces in downflow applications

directly onto combustible flooring material, These kits are

required to prevent potential overheating situations. These kits

are also required in any applications where the furnace in

installed in a downflow configuration without an evaporator coil,

where the combustible floor base kit provides access for com-

bustible airflow.

1CB0514 - For 14-1/2” cabinets

1CB0517 - For 17-1/2” cabinets

1CB0521 - For 21” cabinets

High Altitude Pressure Switches -

For installation where the altitude is less than 5,000 feet it is not

required that the pressure switch be changed. For altitudes

above 5,000 feet, see kits below.

1PS3309

Thermostats - Compatible thermostat controls are available

through accessory sourcing. For optimum performance and

installation, refer to the UPGNET “Low Voltage Wiring Diagram”

document to select and apply controls.

Single side return above 1800 CFM is approved as long as

the filter velocity does not exceed filter manufacturer’s rec-

ommendation and a transition is used to allow use on a

20x25 filter.

Note: Operation at external static pressure higher than rating on furnace data plate is not recommended.

EXTERNAL STATIC PRESSURE SETUP Set appropriate airflow per temperature rise for gas heating. Set

appropriate airflow per Table 14 for cooling/heat pump heating

operating based on outdoor unit size and external static pres-

sure.

To measure external static pressure:

• Measure the supply air static pressure

• Record this positive number

• Measure the return air static pressure

• Record this negative number

• Treat the negative number as a positive and add the two

numbers together

• This is total system static
