GAS-FIRED, SEPARATED COMBUSTION, PROPELLER
• 100% Outside Air for Combustion • Separated Compartment Protects Combination Gas Control, Ignition
Control, Manifold and Burner • Horizontal or Vertical Concentric Venting • 82% Thermal Eciency
• 100% Shut-O with Continuous Retry • Certied for Commercial or Residential Applications
MODEL HDS
MODEL PTS
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 eciency 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 (eld convertible from natural to propane gas).
• Certied 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 simplies 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 congurations.

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
bottom of unit, and without deflector hoods. For units equipped with deflector hoods.
