GENERAL

WARNING: This heater is not intended for use in haz- ardous atmospheres where flammable vapors, gases, liquids or other combustible atmospheres are pre- sent as defined in the National Electrical Code. Failure to comply can result in explosion or fire.

The GCHIS-C is a gas circulation heater, designed especially for low flow rates and/or high temperature applications.

The INCOLOY® sheathed cartridge style heating element is cen- tered in a 304 stainless steel pipe body. High temperature insulation and jacket envelope the pipe body to reduce heat loss. Its screwplug type mounting provides easy removal when necessary.

A Type K thermocouple is located inside the heating element sheath to provide overtemperature protection. Accurate process control can be achieved by means of the Type J thermocouple installed in the heater outlet. (Process and Hi-limit Controllers ordered separately.)

WARNING: Users should install adequate back-up con- trols and safety devices with their electric heating equipment. When heating in closed vessels where the consequences of failure may be severe, controls and back-up controls must be used to prevent buildup of temperature and/or pressure. Although the safety of the installation is the responsibility of the user, Chromalox will be glad to make equipment recommendations.

INSTALLATION

WARNING: Hazard of Electric Shock. Disconnect all power			mounting lugs to support the heater chamber. Refer to figure for
before installing heater.			location of these mounting lugs.
1.	Before installing, check your GCHIS-C circulation heater for any	6. Mount heaters to permit unrestrained expansion of chamber due
			to temperature. This can be accomplished by using slotted mount-
	damage that may have occurred during shipment.
2.			ing assembly on either of the lugs.
	Check to insure that the line voltage is the same as that stamped on
		7. Provide adequate space at terminal end to permit withdrawal of
	the nameplate.
3.			the heater from chamber should servicing be required.
	Vertical mounting (axis of chamber vertical as in figure above)
		8.	DANGER: Hazard of Fire. Provide a minimum of 6” spacing
	is preferred.
4.			from chamber and related piping to nearest combustible material.
	To avoid excess temperatures at electrical wiring, mount heater
			Do not operate heater near combustible fluids or in combustible
	with terminal enclosure at bottom, and use lower nozzle as inlet
			vapor or gas laden atmosphere.
	to the circulating steam, air or gas.
5.		9. If two or more heaters are required to provide the needed heating
	The GCHIS-C series of circulation heaters is provided with
			capacity, arrange them for series gas or vapor flow.
