DESCRIPTION
Two basic types of Ruffneck™ Heat Exchanger configurations are available from CCI Thermal Technologies Inc.:
FR (Frost Resistant) Series - for steam service only, up to 100 psi (690 kPa) on select models
HP (High Pressure) Series - for steam and liquid service up to 400 psi (2,700 kPa) on select models
LOCATION OF HEATERS
The following guidelines have been established by CCI Thermal Technologies Inc. to ensure that you properly locate the
heaters in your building. These are only suggestions, and variations may be deemed necessary depending on application.
1. When occupant comfort is the major objective, heaters should be positioned so that the airflow is directed to areas
of highest heat loss (i.e., doorways, windows and outside walls).
2. For personnel comfort, a less turbulent and more even air distribution is required. To achieve this effect a larger
quantity of smaller unit heaters should be installed.
3. When equipment protection is of utmost concern, heaters should be positioned so that the airflow is directed
towards the equipment.
4. In very large areas, arrangement of heaters should be such that the air will exit from one heater and be projected
towards the inlet, or back, of another heater. A rotational airflow will result, with air circulation in the central area of
the building.
INSTALLATION

5. Installation, piping, and wiring of he heater must adhere to all
applicable codes.
6. It is essential that any unit heater that will be used in a hazardous
(classified) location is equipped with a electric motor approved for
such service, and the temperature of the heat transfer medium is
below the ignition temperature of the atmosphere. Refer to applicable
electrical codes for additional information.
7. Disconnect heater from power supply at integral disconnect or fuse
box before opening enclosures or servicing heater. Lock the switch in
the “OFF” (open) position and/or tag the switch to prevent unexpected
power application. IF INTEGRAL DISCONNECT IS BEING
SERVICED, verify that power has been disconnected at fuse box or

the switch to prevent unexpected power application.
8. Do not operate heater in atmospheres which are corrosive to steel
or aluminum, unless it has been coated with a factory approved
protective coating.
9. For steam service use only single-pass models. Refer to model
coding (page 7) for number of passes in heat exchanger.
10. Refer to heat exchanger data plate for pressure and temperature
limits.
11. Heater must be kept clean. When operating in a dirty environment,
regularly clean the finned tubes, fan and fan guard. Follow the
recommended maintenance procedures. Refer to the “Heater
Maintenance Checklist” section for details.
12. Use factory approved replacement parts only.
13. If there are any questions or concerns regarding the heater, contact
the factory. Refer to the last page of this manual for details.
14. HVAC fluids must be non-flammable, non-compressable, non-
explosive & non-toxic.
15. Do not operate the heater with any of the louvers fully closed or
overriding their stops.
16. Do not operate heater in ambient temperatures above 104°F (40°C).
17. See applicable electrical codes for seal requirements in field installed
conduits. Factory installed conduits require no further sealing.
18. Base of the heater is to be mounted a minimum of 7.9 ft (2.4 m)
above the floor. Refer to the “Installation” section for details.
