CIRCULAR 6-16S C2M O O 1 N E February,t@90 GAS -FIRED DUCT FURNACES application versatility Gas -fired duct furnaces are practically unlimited in their annlinahnn ae _ heat easource in centrpr dtuc- _ 17 Ye „ conditioning or in straight heating systems, as boos!ers and reheat units. for tempering make-up air and in process drying Modine duct furnaces offer the systems designer, the installer, and building owner many important advantages Limitations in installation height can usually be met by using two or more duct furnaces which can be installed side by side or in tandem. Btu requirements exceeding the capacity of the largest model duct furnace may also dictate the combined use of smaller models whose total capacity matches the Btu requirement, when furnaces are installed in combination. they may be operated in- dependently or interconnected for simultaneous automatic operation. Types of gases that may be used are natural and propane product benefits Long -life heat exchangers — Modine heat exchanger de- sign accomodates the need for greater Cfm requirements of air-conditioning systems without the necessity forpro- viding expensive bypass ducts and dampers. Low pres- sure drops and correspr:nding reduced tan horsepower demands are significant advantages of the heat exchanger design. An air distribution baffel (standard on all models) can be removed to further reduce air pressure drop when applied to systems designed for higher Cfm, A.G.A_ and C.G.A. certified for downstream application from cooling coils. Extensive use of corrosion -resistant metal — Important where duct furnaces are used in connection with air- cooling systems. Casing, heat exchanger and burner are made from long -life corrosion -resistant, aluminized steel. Lightweight, trims Installation costs — Corrosion. resistant aluminized steel burners, heat exchangers, and casings contribute toward a drastic reduction in weight. Easier to handle. install faster and save the cost of provid- ing for special ceiling supports and reinforcements. Mounting holes permit easy attachment of 16" diameter rods for overhead suspension. Attachment of ductwork is facilitated by flanges on both sides of heat exchanger section, Self-cleaning, oversize burner ports — Lint -free pilot burner, externally mounted safety control group: combin- ation dram pan and secondary air baffle reduce main- tenance and improve performance of Modine duct furnaces. Automatic controls — Provide complete accessibility and safety Includes t00% gas shut-off system, pressure reg- ulator, over -heat control and tow -voltage transformer with terminal board type connection. Air flow through unit is reversible — Permits locating controls and vent for maximum accessibility.
