Slant/Fin Caravan GGHT-1050 Specification Sheet

GGT SERIES—Gas-Fired/Hot Water
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
heating demands. GGT systems are available in
400,000 to multi-million Btuh gross input. For
additional information, see Caravan Engineering
Manual, pub. C-30 and Caravan gas application
guide, pub. CG-10-HWG.
Standard Equipment
One per module unless otherwise noted:
Pre-assembled cast-iron heat exchanger with
built-in air separators and insulated jacket.
Base.
Flue collector.
Gas burners, gas orifices and manifold assembly.
Combination gas valve including manual shut-off
and pressure regulator.
Pilot adjustment and automatic pilot
thermocouple safety.
Hi-limit control.

* Specify gas by name, "Natural" or
"Propane".
† Net 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 ft. elevation and an additional
4% for every additional 1,000 ft.
elevation over 2,000 ft.
‡ Net ratings in square feet based on
emission rate of 150 Btuh/sq. ft.
§ I=B=R gross output.
Modules in excess of 10 should be
piped in parallel in two or more
batteries. For dimension
specifications, refer to Publication
number CG-10-HWG.
Note: Specify pressure relief setting.
Relief valve is available with
30, 50 or 100 psi.
