WARRANTY SUMMARY
810762-UTG-E-1016
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 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 IV, National Fuel Gas Code and may
be vented either through side wall or roof applications using
approved plastic combustion air and vent piping. Approved
plastic combustion air and vent piping include Selkirk Polyflue,
Duravent Polypro, & Centrotherm Innoflue polypropylene venting systems.
