IMPORTANT INSTRUCTIONS
SSFR series cables increase or decrease the heat output in a self-regulating
way depending on the variation of the ambient temperature. A thermostat may
not be necessary for some applications, and the cable will never overheat or
burn out even when overlapped. The heating cable has a flame-retardant
thermoplastic outer jacket that is resistant to water and inorganic chemicals
and protects against abrasions and impacts. SSFR series cables are suitable
for up to a maximally admissible workpiece temperature of 65°C (150°F).
This self-regulating parallel heating cable can be used for plastic or metal
pipe freeze protection and flow maintenance of pipes, tanks, and valves. It
also can be used in roof and gutter de-icing applications. A UV-stabilized
thermoplastic elastomer outer jacket covers the braid for use in wet
applications and protects it from sun exposure.
This product must be installed correctly to ensure proper operation and
prevent shock or fire. Carefully follow all of the installation instructions
and read these important warnings.
- To minimize the danger of fire from sustained electrical arcing if the heating cable is damaged or improperly installed, and to comply with the requirements of national electrical codes, ground-fault equipment protection must be used on each heating cable branch circuit. Arcing may not be stopped by conventional circuit protection.
- Component approvals and performance are based on the use of specified parts only. Do not substitute parts or use vinyl electrical tape.
- The black heating-cable core is conductive and can be short. It must be properly insulated and kept dry.
- The conductive layer of this heating device must be connected to a suitable grounded terminal.
- The installer should apply the nameplate label to the surface of the junction box.
- Keep kit components and heating cable ends dry before and during installation.
- Damaged bus wires can overheat or short. Do not cut braid or bus wire strands when scoring the jacket or core.
- Bus wires will short if they come into contact with each other. Keep bus wires separated.
- Heat-damaged components can be short. Use a heat gun or a torch with a soft, yellow, low-heat flame, not a blue-focused flame. Keep the flame moving to avoid overheating, blistering, or charring the heat-shrinkable tubes. Avoid heating other components. Replace any damaged parts.
- Use only fire-resistant insulation materials such as fiberglass wrap.
- Leave these installation instructions with the user for future reference.
- The cable should not be twisted during installation.
- De-energize all power circuits before installation or servicing.
- The heating cable should not be embedded.
WARNING: Improper installation, use, operation, or maintenance of this
product may result in injury or death from electric shock or fire. It may also
result in property damage from ice dams. Make sure the chosen heating cable is
suitable for your application.

- The cell at that intersection has a particular shading and may have a number. The shading indicates which heating cable to use (the key to the shading appears below the tables). A number represents the spiraling ratio (feet of heating cable per foot of pipe). If no number appears in the cell, straight trace the pipe. If a number does appear in the cell, spiral trace the pipe. If your spiraling ratio is 2, the length of the cable must be twice as long as the pipe.

PIPE
ELECTRICAL CODES
Articles 427 of the Electrical Code and Section 62 of CAN/CSA-C22.1,
Canadian Electrical Code, govern the installation of Self-regulating freeze
protection reel cables (SSFR series cables) for pipe freeze protection.
IMPORTANT: For the warranty to be valid, you must comply with all
requirements outlined in these guidelines. All design information provided
here is based on a standard installation with a heating cable fastened to an
insulated pipe.

For the maximum heating cable circuit length allowed for a given circuit breaker rating, we also provide examples. Refer to Table 3. Determine your circuit length based on your lowest anticipated start-up temperature.
GROUND FAULT PROTECTION
The National Electrical Code and Canadian Electrical Code require ground-fault
equipment protection on each heating cable branch circuit. To reduce the risk
of fire caused by damage or improper installation, circuit breakers, or their
equivalents, a 30-mA trip level should be used. Alternative designs providing
comparable levels of ground-fault protection may also be acceptable.
WARNING: Ensure only qualified persons service the installed systems.
WARNING: Continuous circuit operation is necessary for the safe operation
of the equipment or manufacturing process.
NOTE: Accessories are sold separately.
PREPARE FOR INSTALLATION
- Use a megohmmeter to test each reel of the cable according to the instructions in the “Heating cable testing and maintenance” section.
- Store the heating cable in a clean, dry place.
- Complete pipe pressure test.
- Review the heating cable design and compare it to materials received to verify that the proper SSFR heating cable and accessories are available. The heating cable type is printed on the outer jacket of the cable.
- Analyze the system and plan the routing of the SSFR heating cable on the pipe.
- Verify that the heating cable is the correct factory fabricated unit or bulk cable type before installation (wattage output and voltage rating).
- For field-assembled systems, verify that the components are designed, or recommended, for the specific heating cable used.
- All welding, hydrostatic testing, and painting of pipe should be completed before heating cable installation.
- Inspect the piping system to ensure it is clean and has no sharp or jagged edges that might damage the heating cable.
- Installation of the heat tracing before completion of the piping system is not recommended.
CUT THE HEATING CABLE TO THE REQUIRED LENGTH
- Cut the heating cable to the required length. This can be done before or after the cable is attached to the pipe.
- Leave a minimum of 1 ft (30 cm) extra heating cable for connection to power. For splice and tee connections, leave a minimum of 1 ft (30 cm) for each section of the heating cable. SSFR heating cable can be cut to the required length without affecting its heat output per foot.
POSITION AND ATTACH HEATING CABLE TO PIPE
- Make sure all pipe to be traced is dry.
- Install heating cable using straight, spiraling, or multiple tracing according to the “Heating cable selection and design” section.
- For straight tracing, install the heating cable on the lower half of the pipe, e.g., in the 4 o’clock or 8 o’clock position.
- Make sure to install the additional heating cable required for valves, flanges, etc. as indicated in Step 2 of the “Heating cable selection and design” section.
- When the design needs spiraling, begin by suspending a loop every 10 ft (3 m) as shown in Figure 1. To determine the loop length, obtain the spiral factor from Table 1 or 2 and multiply by 10. For instance, if a spiral factor of 1.3 is called for, leave a 13 ft (4 m) loop of heating cable at every 10 ft (3 m) section of pipe. Grasp the loop at its center and wrap it around the pipe. Even out the distance between spirals by sliding the wraps along the pipe. Use SSFR-FIBTAPE Fiberglass adhesive tape to secure the center of the loop to the pipe. Secure the heating cable flat to the pipe to ensure good contact.
- Tape SSFR heating cable to the pipe at intervals of 2 ft (60 cm) using SSFR-FIBTAPE fiberglass adhesive tape. Do not use vinyl electrical tape, duct tape, metal bands, or wire.
- On plastic pipes, attach the full length of the cable with SSFR-ALUTAPE aluminum adhesive foil tape.
- Protect the heating cable ends from moisture or mechanical damage if they will be left exposed before connection.
INSTALL HEATING CABLE END SEALS, SPLICES, TEES, AND POWER CONNECTION
- Install all end seals, splices, and tees and the power connection prior to plugging in the cable.
- If splicing or teeing, use only the SSFR10 splice and tee kit, SSFR-SPLICE splice kit, or SSFR-TEE tee kit to satisfy National Electric Code and safety agency requirements.
CHECK THE INSTALLATION
- Prior to installing thermal insulation, make sure the heating cable is free of mechanical (form cuts, clamps, etc.) and thermal (soldering, overheating, etc.) damage.
- Visually check all power connections, end seals, splices, and tees.
- Using a megohmmeter, test each circuit according to the instructions in the “Heating cable testing and maintenance” section both before and after installing the thermal insulation.
INSTALL THERMAL INSULATION
- A reliable system depends on properly installed and weatherproofed thermal insulation.
- Ensure that the type and thickness of the insulation are in accordance with the heating cable selection information.
- External surfaces of pipeline and vessel heating equipment that operate at temperatures exceeding 60°C (140°F) must be physically guarded, isolated, or thermally insulated to protect against contact by personnel in the area. Tables and all pipe work including valves, joints, wall penetrations, and other elements have been fully insulated.
- Minimize the potential for mechanical damage to the heating cable after installation by installing the insulation as soon as you have checked the cable installation.
LABEL THE INSTALLATION
Place warning labels for pipe trace applications on the outer surface of the insulation at intervals of 10 ft (3 m) on alternating sides of the pipe to indicate the presence of an electric heating cable. Additional labels and application tape are contained in the SSFR03 kit.
CHECK THE INSTALLATION
- Prior to power, check to be sure the heating cable is free of mechanical damage (cuts, clamps, etc.).
- Visually check all power connections, end seals, splices, and tees for proper installation.
- The field-wiring leads must have a current rating not less than the current rating of the heating tracing.
- Using a megohmmeter, test each circuit according to the instructions in the “Heating cable testing and maintenance” section below.

NOTE:
- The roof extension takes into account the length of cable needed to reach the cable laid in the gutter (from the roof edge).
- In-line splices and tee splices should be avoided where possible.
- Heating cable in downspouts should be looped (2 ft [61 cm] of heating cable per feet [30 cm] of downspout) and should extend below the frost line if tied into a drainage system.
- Field-assembled end terminations should not be located in an area where moisture is present. End terminations should not be located at the lowest point of downspouts.
- The circuit length for a given overcurrent protection device must not exceed the maximum length specified by the manufacturer.
- The maximum exposure temperature of all roof, gutter, and downspout materials must be verified, and the heating cable selected must not exceed its temperature ratings.
- For roof drains leading into a heated area, a loop of heating cable is installed to a typical depth of 3 ft (1 m).
EXAMPLE (SHINGLE ROOF):
- Roof edge: 40 ft
- Roof extension: 20 ft
- Valley: 0
- Roof overhang: 1 ft
- Roof gutter: 40 ft
- Downspout: 15 ft
- Power connection: 1 ea.
- Tee connection: 0
- End seal: 1 ea.
- Voltage available: 240 V
- Heating cable: SSFR2W08
Length of heating cable required:
Roof edge | 40 ft × 2 (see Table 4 ) = | 80 ft |
---|---|---|
Roof extension | 40 ft x 0.5 = | 20 ft |
Roof gutter | 40 ft | 40 ft |
Downspout | 16 ft | 16 ft |
Power connection | 1 ft × 1 ea. | 1 ft |
Tee connection | 0 | 0 ft |
End seal | 0.5 ft x 1 ea = | 0.5 ft |
Total | 157.5 ft |
This total is less than the 188-ft maximum circuit length; therefore only one circuit is required.
DETERMINE THE MAXIMUM HEATING CABLE CIRCUIT LENGTH ALLOWED
See Table 3 on page 5. Ensure that your circuits do not exceed the maximum
circuit length listed in the table. If necessary, use additional shorter

TOOLS REQUIRED
*The string should be at least as long as the longest downspout.
PREPARE FOR INSTALLATION
- Secure the heating cable in accordance with Article 426 of the NEC.
- Store the heating cable in a clean, dry place.
- Use only the following SSFR accessories to satisfy National Electric Code and safety agency requirements: see accessories required.
- Carefully plan the routing of the heating cable for roof and gutter de-icing.
- Make sure that gutters and downspouts are free of leaves and other debris.
- The mounting surface must be inspected for sharp edges where the heating cable will be located (and removed as necessary).
- A listed weatherproof power connection should be located and mounted in a sheltered area.
CUT THE CABLE TO THE REQUIRED LENGTH
- Cut the heating cable to the required length. This can be done before or after it is installed. Leave a minimum of 1 ft (30 cm) extra heating cable for electrical connections. For splice and tee connections, leave a minimum of 1 ft (30 cm) for each section of the heating cable. SSFR heating cable can be cut to the required length without affecting its heat output per foot.
- Protect the heating cable ends from moisture and mechanical damage if they will be left exposed before connection.
POSITION AND ATTACH THE CABLE TO THE ROOF
- Loop the heating cable on the overhang area of the roof. This is the part that extends past the building wall. Extend the bottom of each heating cable loop over the roof edge, and using a cable tie, connect the bottom of each loop to the cable running in the gutter to ensure a drainage channel off the roof into the gutters and downspouts. The cable running in the gutter should remain against the bottom of the gutter. Extend the top of each heating cable loop beyond where the wall joins the roof. We recommend a spacing of 2 ft (60 cm) between each clip along the roof edge. See the “Heating cable design” section (Table 4) for spacing and layout information.
- Use SSFR13/SSFR14 roof clips to attach the heating cable to the roof surface. One SSFR13 kit contains 10 double roof clips for approximately 7 linear ft (2.1 m) of the roof edge. One SSFR14 kit contains 50 roof clips for approximately 35 linear ft (10.7 m) of the roof edge.
- For flat roofs, the heating cable can be spaced as needed to create runoff paths for melting ice and snow. Use single-ended clips located at intervals of 3 ft (0.9 m) to secure the cable to the roof. Roof clips may be attached to a shake or shingle roof with nails or screws, as shown in Figures 2 and 3. Reseal the nail or screw holes if necessary before installing a heating cable in the clips. Roof clips may be attached to a metal roof using a screw, nail, or adhesive.
- All penetration made on the surface of any style of the roof should be moisture proofed by using a suitable sealant or sealing type fasteners. The installation of any heating system must not affect the overall integrity of the roof or gutter.
- The mounting hardware must be made of corrosion-resistant material and should not have sharp edges or burrs that could damage the heater cable.
- Trace two-thirds of the way up each valley with a double run of heating cable, as shown in Figure 4.
POSITION AND ATTACH THE CABLE IN GUTTERS AND DOWNSPOUTS
- Run the heating cable along gutters and into downspouts, ending below the freezing level. A permanent attachment of the cable to the gutter bottom is not necessary. Loop the heating cable in downspouts if convenient, such as when the downspout is not at the end of the run, or use the SSFR10 splice and tee kit to tee down the downspout, as shown in Figure 5.
- Use SSFR15 downspout hangers to protect the heating cable from fraying and damage from sharp edges and to provide strain relief. Refer to SSFR15 kit instructions for installation details.
- Use SSFR13/SSFR14 roof clips to route heating cable into and out of the gutters in such a way as to prevent abrasion to the cable. Protect all cable that protrudes past the lower opening of the downspout.
INSTALL HEATING CABLE END SEALS, SPLICES, TEES, AND POWER CONNECTION
- Install all end seals, splices, and tees and the power connection prior to plugging in.
- Follow the SSFR00 or SSFR08 kit installation instructions.
- Use only listed weatherproof junction boxes approved for wet locations when installing SSFR heating cables with the SSFR08 power connection kit for roof and gutter applications.
- Use only listed watertight construction or Type 3, 3s, 4, 4X, 6, or 6P enclosure junction boxes when installing.
- Use only the listed weatherproof type wiring cable from the circuit breaker to the power connection box. The cable should be protected from damage by installing it in a rigid metal or nonmetallic raceway.
- When possible, all power connection boxes should be located in a protected area (such as under eaves), and the entry should be at the bottom of the box. In all cases, a drip loop should be provided.
LABEL THE INSTALLATION
Two copies of a caution notice indicating the presence of electric deicing and snow-melting equipment on the premises are packed with the SSFR00 unit. One notice must be posted at the fuse or circuit breaker panel and the other on or next to the on/off control for the cable unit. Both notices must be clearly visible.
CHECK THE INSTALLATION
- Prior to power, check to be sure the heating cable is free of mechanical damage (cuts, clamps, etc.).
- Visually check all power connections, end seals, splices, and tees for proper installation.
- Using a megohmmeter, test each circuit according to the instructions in the “Heating cable testing and maintenance” section below.
- Junction boxes should be inspected for water or evidence of previous water ingress. If moisture is present, the box should be restored to a dry condition and the cause of ingress should be eliminated.
- The functionality of overcurrent protection devices must be checked.
NOTE:
- Do not cross or overlap cable heating sections.
- The cable must be installed 10 in. (25.4 cm) away from combustible surfaces such as wood.
- The minimum bending radius of each heating cable is 1.5 in. (38.1 mm).
- In all locations, route and secure cable to avoid possible mechanical damage, such as from ladders, etc.
- All actual lengths installed should be recorded. The installer should provide installation drawings and data.
- The minimum installation temperature for the heating cable is 0°F (-18°C).
TESTING AND MAINTENANCE
We recommend that the insulation resistance between the bus wire and the
heating cable grounding braid or metal pipe should be checked during
installation using a 2500-VDC megohmmeter (500 VDC minimum). The minimum
reading should be 20 megohms, regardless of length.
Record the original values for each circuit. Take additional readings during
regularly scheduled maintenance and compare them to the original value. If the
readings fall below 20 megohms, inspect cables and insulation for signs of
damage.
If physical damage is found, the entire damaged section must be removed and a
new section of heating cable spliced in using only approved SSFR10 or SSFR-
SPLICE splice kits. Do not repair the damaged heating cable section. If
physical damage cannot be found, the complete circuit should be removed and
replaced with a new SSFR heating cable.
WARNING: Shock and fire hazard. Damaged heating cable or components can
cause electrical shock, arcing, and fire. Do not attempt to energize damaged
cable or components. Replace them immediately using a new length of heating
cable and the appropriate SSFR accessories.

CONDITIONS, EXCLUSIONS, AND DISCLAIMER OF LIABILITY
This warranty is exclusive and in lieu of all other representations and
warranties (except title), expressed or implied, and °STELPRO expressly
disclaims and excludes any implied warranty of merchantability or implied
warranty of fitness for a particular purpose.
°STELPRO’s liability with respect to products is limited as provided above.
°STELPRO shall not be subject to any other obligations or liabilities
whatsoever, whether based on contract, tort or other theories of law, with
respect to goods or services furnished by it or any undertakings, acts, or
omissions relating thereto. Without limiting the generality of the foregoing,
°STELPRO expressly disclaims any liability for property or personal injury
damages, penalties, special or punitive damages, damages for lost profits,
loss of use of equipment, cost of capital, cost of substitute products,
facilities, or services, shutdowns, slowdowns, or for other types of economic
loss or for claims of a dealer’s customers or any third party for such
damages. °STELPRO specifically disclaims all consequential, incidental, and
contingent damages whatsoever.
This warranty does not cover any damages or failures resulting from 1) a
faulty installation or improper storage; 2) an abusive or abnormal use, lack
of maintenance, improper maintenance (other than that prescribed by °STELPRO),
or use other than that for which the unit was designed; 3) a natural disaster
or an event out of °STELPRO’s control, including, but not limited to,
hurricanes, tornadoes, earthquakes, terrorist attacks, wars, overvoltage,
flooding, water damages, etc. This warranty does not cover any accidental or
intentional losses or damages, nor does it cover damages caused by the
negligence of the user or owner of the product. Moreover, it does not cover
the cost of disconnection, transport, and installation.
The warranty is limited to the repair or the replacement of the unit or the
refund of its purchase price, at the discretion of °STELPRO. Any parts
replaced or repaired within the warranty period with the written authorization
of °STELPRO will be warranted for the remainder of the original warranty
period. This warranty will be considered null and void and °STELPRO will have
the right to refuse any claims if products have been altered without the
written authorization of °STELPRO and if the nameplate numbers have been
removed or modified. This warranty does not cover scratches, dents, corrosion,
or discoloration caused by excessive heat, chemical cleaning products, and
abrasive agents. It does not cover any damage that occurred during the
shipping.
Some states and provinces do not allow the exclusion or limitation of
incidental or consequential damages and some of them do not allow limitations
on how long an implied warranty lasts, so these exclusions or limitations may
not apply to you. This warranty gives you specific legal rights and you may
have other rights which vary from state to state or from province to province.
