RCL Roy Campbell Ltd Revised: 19 May 2016 Consulting Electrical Engineers

PART 1 - GENERAL 1.1 DOCUMENTS .1 This section of the specification forms part of the Contract Documents and is to be read,

interpreted, and coordinated with all other parts. PART 2 - PRODUCTS 2.1 ELECTRIC HEATING .1 Install electric heaters where shown on the drawings and supply units and accessory

equipment as specified in Electric Heater Schedule. Ouellet heaters are specified; other approved manufacturers include:

o Dimplex o Ouellet o Stelpro

.2 Electric heater controls shall be built-in or wall mounted thermostats as detailed on the

drawings. Where control transformers, low voltage relays, etc., are shown, they shall be built into the electric heaters.

.3 All heaters shall be securely fastened and seismically secured to structural wall or ceiling

elements such as studs or joints. 2.2 PIPE HEAT TRACING SYSTEM - SELF REGULATING .1 General Supply and install a complete electric tracing system consisting of the following:

o Electric heating cables o Temperature controllers and auxiliaries o Accessory materials such as banding, junction boxes, etc.

Approved Manufacturers:

o Ray Chem XL-Trace o Serge Baril Type ‘CCA’

Heating cables shall be of the mineral insulated type, fabricated to the length required.

This length shall consist of the length required for the pipe to be heated, and allowance for areas of additional heat loss of valves, flanges, fittings, and the like, plus a reasonable excess to allow for field variations. Verify cable lengths with the manufacturer's representative prior to placing of order. Heating cables shall be designed for operation at 120 Volts as detailed on the drawings.



The following minimum heat wattages shall be installed:

Pipe Diameter Minimum Heat Requirements

½” (13mm) 3 watts/ft. (3 watts/300mm)

¾” (19mm) 4 watts/ft. (4 watts/300mm)

1” (25mm) 5 watts/ft. (5 watts/300mm)

1¼” (32mm) 5 watts/ft. (5 watts/300mm)

1½” (38mm) 6 watts/ft. (6 watts/300mm)

2” (51mm) 4 watts/ft. (4 watts/300mm)

All lines shall have 2” insulation which will be supplied and installed by others. .2 Power Supply All heat tracing cables shall be supplied from a 30 mA ground fault protection device

(GFPD) breaker. Approved Manufacturers:

o Cutler Hammer Type GHBGFED o Square ‘D’ Type QO-EPD

.3 Control All heating circuits shall be thermostatically controlled. Thermostats shall be located in

an inconspicuous location with overall guard or as shown on the drawings. Where the rating of the thermostat would be exceeded, it shall be used in conjunction with a relay or contactor.

Branch circuit conduit and wiring has been shown from the panelboard to the heating

circuits. If the electric loads of the heating circuit exceed the branch circuit wiring capacity, the wiring shall be increased to suit.

.4 Installation Requirements The complete electric tracing system shall be installed to the manufacturer’s

recommendations. Field testing of insulation resistance and continuity of the units shall be carried out with a 500 volt insulation tester and recorded. Testing shall be done when received on the jobsite after installation on the pipe and after the heat insulation has been installed. Insulation resistance shall be consistently not less than 5 megohms with no decline in reading.

Heating cables shall not be installed until a written release is received indicating that the

pipes are completely installed and welded and have passed all necessary tests. Cable sheaths shall not cross or touch one another nor shall cables be installed directly on top of pipe.

Heating cable shall be strapped to 4” and larger pipe using 13mm (½" wide stainless

steel strapping at intervals not exceeding 30”. Copper or stainless steel tie wire #18 AWG, or larger, shall be used to hold the cable to irregular surfaces such as valves. Tie



wire and strapping shall be snug but not so tight as to indent cable sheath. After completion of strapping on PVC piping cable shall be continuously secured longitudinally with aluminum tape supplied by manufacturers.

Extra cable shall be provided in areas of increased heat loss such as valves, and flanges

to allow dismantling and removal of equipment. Thermostat bulb to be located as far away from heating cable as possible. Thermostat capillary and control wiring shall have mechanical conduit protection between the equipment rack and the pipe line. Junction boxes, thermostats, transformers and the like shall not be attached to the insulation, but shall be mounted on brackets fabricated to galvanized angle, channel or other material of sufficient strength to support equipment mounted on them.

Electrically heated pipe lines shall have adhesive-backed labels on the outside of the

insulation cover at intervals not exceeding 30.5 m (100') which read ‘electrically traced’. In the panelboard feeding the heating cables each circuit shall be marked with the name, location, voltage and wattage of the circuit. Energizing of the heating cable shall not be done without first contacting the heating cable manufacturer's representative.

.5 Shop Drawings and Project Record Documents Drawings showing the selected cable numbers, wattage and circuit number shall be

submitted for approval. They shall also show location of thermostats, relays and contactors on plan. These drawings shall be corrected to include on site modifications and be included as part of the Project Record Documents.
