GAS-FIRED, SEPARATED COMBUSTION, PROPELLER
• 100% Outside Air for Combustion
Control, Manifold and Burner
• 100% Shut-Off with Continuous Retry
MODEL HDS
MODEL PTS
• Separated Compartment Protects Combination Gas Control, Ignition
• Horizontal or Vertical Concentric Venting
• Certified for Commercial or Residential Applications
The separated combustion models HDS and PTS draw 100% of their combustion air from
outside to ensure that the unit will always have plenty of fresh, clean air to breathe. This
fresh-air supply reduces common concerns about maintenance, performance, and
durability in dusty, dirty, or humid applications. In addition, by drawing the combustion
air from the outside, the overall heating efficiency is increased. In short, the separated
combustion units give you the added advantages of:
• 82% thermal efficiency for fuel savings.
• A separated compartment protects the combination gas valve, ignition control, manifold,
and burner from the environment.
• External gas connections.
• Uses natural or propane gas (field convertible from natural to propane gas).
• Certified for residential (30-125MBH), commercial and industrial use (30-400MBH).
• Lightweight, easily installs 1" from ceiling with only two angle brackets (standard on 30-75,
accessory for 100-125).
• Install quickly and easily with knockouts for quick access to gas and electricity.
• Standard power exhaust simplifies side-wall or roof venting with small-diameter vent pipe.
• Horizontal or vertical two-pipe or concentric venting options.
• Permanently-lubricated motor for trouble-free dependability.
• Full 10-year warranty on heat exchanger.
• Available in both propeller fan and centrifugal blower configurations.

j Ratings shown are for elevations up to 2,000 Ft. For elevations above 2,000 feet, ratings should be reduced at the rate of
4% for each 1,000 feet above sea level. (In Canada see rating plate.) Reduction of ratings requires use of a high altitude kit.
k Data taken at 55°F air temperature rise. At 65°F ambient and unit fired at full-rated input. Mounting height as measured from
