Jackson & Church HVAC Global Self-contained Indirect Fired Systems are designed, constructed and evaluated to meet or exceed industry standards as a cETLus Listed package. The indirect fired product is an ANSI classified Category IV appliance, as potential of flue gases to condense exists, particularly in large air volume systems and when high turn down fuel burning equipment is employed. Other available compliance standards include UL, FM Global, GAP and construction suitable for use in NEMA classified indoor or outdoor non-hazardous locations.
Flexible Heating Options
The Indirect Fired Systems incorporates standard fuel burning equipment that utilizes a forced draft combustion system. Fuel options include natural gas, LPG and CS #2 fuel oil as well as combination fuel input arrangements to 4,000 MBH (1010 Mcal/hr) output with optionally available hot water, steam and electric heat. Fuel Burning Equipment configurations are available for high elevation operation and low emission performance applications.
An induced draft fan facilitates a negative pressure condition within the combustion chamber. This assures combustion stability and aids in preventing escape of flue gases to tempered occupied spaces in the event of heat exchanger integrity failure. The flexible design permits optional chilled water and direct expansion coil cooling mediums to 100 tons capacity.

Series SDF-AF Packaged Axial Flow
Air Turnover System
For large open space applications such as warehousing and manufacturing, the vertically configured Series SDF-AF incorporates a large volume axial fan assembly for continuous air turnover for ductless operation and can be configured for outdoor installation. The energy-efficient axial fans provide air turnover rates of 1 to 4 times each hour mixing the air thoroughly, preventing air stratification, for uniform temperature and humidity from floor to ceiling.
Series OL and GA Indoor Packaged
Centrifugal Systems
The Series OL – CS #2 fuel oil fired and Series GA – natural gas or LPG fired indoor packaged centrifugal air handler is available to 450 MBH output in various discharge arrangements. The systems are particularly suited for commercial applications requiring durable construction and long life cycle service.
The 12 gauge carbon steel heat exchanger incorporates a stainless steel combustion chamber to ensure non-impingement of fuel burner flame pattern. The unit heat exchanger and centrifugal fan section are encased within an integral cabinet and shipped for final assembly in the field. Optional inlet filter, discharge louver and plenums are available.
