SPECIFICATIONS

The Model 125-379, a 125, 000 Btuh furnace, is AGA listed for outdoor installation. The unit is also available with a factory installed chilled water coil. The 36D-379 is rated at 36,000 Btuh cooling capacity.

This equipment has been specifically designed for use on applications where a heating unit suitable for outdoor installation has been specified.

Rated at 125,000 Btuh heating input, this unit is constructed and tailored for conamercial duty - yet it is ideally suited for residential applications.

Installation does not interfere with other building trades - no inside floor space and no special vents are required. Just set unit on slab or adequate roof support then connect duct, gas supply, and electric supply.

The insulated weatherproof cabinet is made from heavy gauge zinc coated steel; the finish is baked-on enamel. Removable panels allow easy access to all components and controls. Automatic pilot reignition eliminates the need for service calls just to light the pilot. A stainless chromized steel heat exchanger promises long life.

Standard equipment includes;

• Blower relay • Condensate pan • Hi-limit control e Adjustable fan control

• Weatherproof insulated cabinet e Combination manual A & В valve and regulator

• Natural D1 and Propane D9 controls • Stainless steel chromized heat exchangers

• Bryant automatic pilot e Blower motor direct drive e Bryant diaphragm gas valve

• Chilled water coil • Electric re-ignition • Slotted port burners • Cooling fan relay
