DESCRIPTION
These compact units employ induced combustion, reliable hot
surface ignition and high heat transfer aluminized tubular heat
exchangers. The units are factory shipped for installation in
upflow applications and may be converted for downflow applications.
These furnaces are designed for residential mobile home, manufactured, or modular home installation. All units are factory
assembled, wired and tested to assure safe dependable and
economical installation and operation.
These units are Category IV direct vent, sealed combustion
listed and may be vented either through side wall or roof applications using approved plastic combustion air and vent piping.
WARRANTY
15-year limited warranty on the heat exchanger.

FILTER PERFORMANCE
The airflow capacity data published in the “Blower Performance” table listed below 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 cabinet. 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 recommendation and a transition is used to allow use on a 20x25
filter (upflow only).
Recommended Filter Sizes (High velocity 600 FPM)
CFM
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 minute (91.4 m/min). All velocities over this requ ire the use of h igh vel oci ty f ilters.
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.
