GCH and GCHIS-6 Circulation Heaters
For Steam, Gas and Air Heating
Read and understand all instructions before
installing, servicing or operating product. Failure
to do so could result in personal injury or property
damage.
The GCH and GCHIS-6 series is a general-purpose gas or steam
circulation heater intended for use indoors.
The 6 INCOLOY® sheathed tubular elements are centered in a 5”
diameter heating chamber and welded to a removable flange. The
assembly is surrounded by 1-1/2” insulation and sheet metal jacket.
The GCH series has a steel flange and chamber. The GCHIS series has
stainless steel flange and chamber.
Depending upon the order specifications, the GCH-GCHIS-6 may
or may not be factory equipped with an AR or other Chromalox ther-
mostat. Such thermostats function to control outlet temperatures and to
limit internal temperatures under abnormal flow conditions. These
controls do not fail safe.
The system designer is responsible for the safety
of this equipment and should install adequate
back-up controls and safety devices with their
electric heating equipment. Where the conse-
quences of failure could result in personal injury or
property damage, back-up controls are essential.
