718446-YTG-B-0113 • More Attractive Appearance - A single piece Water Shed top cover containing a top discharge condenser fan arrangement requires less square footage on installation and provides a wider variety of installations. The one piece design adds greater water integrity. Rounded corners with water drip edges add to the attractive appearance. The cabinet panels have a non-fibrous insulation that will not release insulation fibers into conditioned area.

718446-YTG-B-0113 • High Altitude Conversion Kit (Natural Gas/Propane) - Kit includes all necessary labels and instructions to field alter units with natural gas/propane for installations above 2000 feet. Burner orifices must be obtained from Source 1 Parts. Propane Conversion Kit must be obtained separately. • Economizer Down Discharge/Supply Kit - Modulating integrated economizer provides simultaneous operation between the mechanical cooling and economizer operation.
