4. Mechanical Installation

Location

1. Model CXH-A/B heaters are certified for hazardous loca-

tions listed in table C. When un-crating confirm name-

plate (located on control enclosure lid on left side of heat-

er) matches what was ordered. If listing does not meet

hazardous location requirements, contact Chromalox im-

mediately.

2. Prior to installation ensure that heater configuration meets

environmental requirements. Model CXH-A/B heater are

designed with corrosion and moisture protection, but it is

the responsibility of the end user to ensure that materials

are compatible with the application conditions.

3. Location should be free of interference from columns,

machinery and partitions, and should allow for required

clearances (see Mounting).

4. Outlet air is hot, so avoid locations where heaters may

blow directly at personnel.

Mounting

1. Model CHX-A/B heaters are designed for use only in a

permanently mounted upright position. The maximum

out of plane dimensions as shown in Figure 2 must not be

exceeded in either direction during operation and instal-

lation. Failure to comply may cause nuisance tripping of

over-temperature cutout.

2. The ceiling or wall mounting surface and the anchoring

must be sufficient to support the combined weights of

the heater and mounting hardware (heater weights are

listed in Table A).

3. Heaters may be mounted at any convenient height above

floor. The minimum spacing shown in Figure 3 should be

maintained to adjacent walls and ceiling. If floor heat is

desired, do not mount higher than 8 to 10 feet (2.4 to 3.0

meters) above floor.

4. Controlling thermostats to individuals should be mount-

ed at shoulder height on inside walls or columns clear of

the discharge air stream of the unit. Allow at least 4 feet

(1.2m) in front of heater for air stream to discharge freely.

Do not mount mercury type thermostat directly on unit,

vibration could cause malfunction.

5. For best performance, locate heaters according to figure

1. This will promote optimal air circulation and eliminate

hot or cold spots. Heaters should blow air parallel to ex-

posed walls (do not blow directly at and should be instal

led along the windward side when installed in a building

exposed to a prevailing wind.

Figure 1 – Mounting Location

5. Heater may be mounted on a shelf or stand from the bot-

tom. Be sure that mounting clearances are maintained

and that bottom of unit has at least 1" (25mm) clearance

underneath it. This is necessary for good air circulation

and servicing of heat exchanger. All mounting methods

must allow for removal of front cover.

6. Mounting and anchoring provisions must take into ac-

count the unit vibration and cantilevered loading when

wall or pole mounted. Heater weights are listed in tables

A and B within the Specifications and Product Identifica-

tion section of the manual.

7. For proper mounting support, it is recommended that a

Chromalox supplied wall, ceiling, or pole mounting kit be

utilized.

These kits include brackets and heater installation hard-

ware. Refer to document PF458 for mounting kit installa-

tion.

8. CXH-A/B heaters are equipped with two threaded mount-

ing points (5/8-11 UNC) located on the top of the heater

case that may used to be anchor the heater to an alter-

native mounting structure using 5/8-11 (UNC) bolts and

lock-washers.
