Slant/Fin Caravan LDZO-1100-3-6 Specification Sheet

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.

† 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
