Slant/Fin Caravan Hot Water Modular Boiler, GGT and GGHT Series

Slant/Fin Caravan GGT GGHT Series

A Caravan modular boiler system is the smart way to heat your building. It's easy to size a system to your individual heating requirements, or to add to the system later should your needs change. By step-firing just enough modules to meet demand. Caravans are cast iron's answer to modulating boilers and will increase the efficiency of the entire system.

NOTES:

  • Net AHRI ratings are based on piping and pick-up allowance of 1.15. Slant/Fin should be consulted before selecting a boiler for installation having unusual piping and/or pick-up requirements. Ratings must be reduced by 4% at 2,000 feet elevation and an additional 4% for every additional 1,000 feet elevation over 2,000 feet.
  • Net ratings in square feet based on emission rate of 150 Btuh/sq. ft.
  • Modules in excess of 10 snould be piped in parallel in two or more batteries. For dimensional specifications. refer to Publication number CG-10HWG.
  • Specify pressure relief setting. Relief valve is available with 30, 50, 75 or 100 psi.
