FILTER PERFORMANCE

The airflow capacity data published in the “Blower Perfor- mance” table 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.

NOTE: 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 of a 20 x 25 filter.

Recommended Filter Sizes

CFM	Cabinet	Side	Bottom
	Size	(in)	(in)
1200	B	16 x 25	16 x 25
1600	C	16 x 25	20 x 25
2000	C	(2) 16 x 25	20 x 25
2000	D	(2) 16 x 25	22 x 25

NOTES:

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.

ACCESSORIES

Propane (LP) Conversion Kit -

1NP0681 - All Models

This accessory conversion kit may be used to convert natural gas (N) units for propane (LP) operation.

Do not use Conversion Kit S1-1NP0680 with these models, as the control/gas valve combination have been updated, and that kit S1-1NP0680 will not function correctly with these models.

Concentric Vent Termination -

S1-1CT0302 (2")

S1-1CT0303 (3")

For use through rooftop, sidewall. Allows combustion air to enter and exhaust to exit through single common hole. Elimi- nates unslightly elbows for a cleaner installation.

Johnson Controls Unitary Products

538513- YTG-A-0809

Sidewall Vent Termination Kit -

S1-1HT0901 (3")

S1-1HT0902 (2")

For use on sidewall, two-pipe installations only. Provide a more attractive termination for locations where the terminal is visable on the side of the home.

Condensate Neutralizer Kit -

1NK0301

Neutralizer cartridge has a 1/2" plastic tube fittings for installa- tion in the drain line. Calcium carbonate refill media is also available from the Source 1 Parts (p/n 026-30228-000).

Side Return Filter Racks -

1SR0200 - All Models

1SR0402 - All Models

1SF0101 - All Models

Bottom Return Filter Racks -

1BR0517 or 1BR0617 - For 17-1/2” cabinets 1BR0521 or 1BR0621 - For 21” cabinets 1BR0524 or 1BR0624 - For 24-1/2” cabinets

1BR05xx series are galvanized steel filter racks. 1BR06xx are pre-painted steel filter racks to match the appearance of the fur- nace cabinet.

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.

1CB0517 - For 17-1/2” cabinets 1CB0521 - For 21” cabinets 1CB0524 - For 24-1/2” cabinets

EAC Transition Kits -

For installation of EAC accessories with these furnaces to pro- vide easy transition of return airflow through the EAC to get the proper sealing and reduced airflow leakage.

1TK1001 - For all models using side return 1TK1017 - For 17-1/2” cabinets using bottom return 1TK1021 - For 21” cabinets using bottom return 1TK1024 - For 24-1/2” cabinets using bottom return

High Altitude - No high altitude kits are required.

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.
