LDZO SERIES—Oil-Fired/Steam

A Caravan modular boiler system consists of two or more compact cast-iron boilers that offer significant advantages in terms of installed cost, efficiency and reliability. Caravan systems are based on step-firing just enough modules to meet space heating demands. LDZO systems are available in 602,000 to multi-million Btuh gross input. For additional information, see Caravan Engineering Manual, pub. C-30.

* Light oil, 140,000 Btu. per gallon.

†Net ratings are based on piping and pick-up allowance of 1.33. Slant/Fin should be consulted before selecting a boiler for installation having unusual piping and/or pick-up requirements. For higher elevations, input may need to be reduced

‡ Based on 240 Btuh per square foot E.D.R. at 215˚F average steam temperature.

Modules in excess of 5 are piped in parallel in two or more banks.
