2 lectric olutions to Cold Weather roblems asy Heat s R Trace offers an effective solution to cold-weather-related problems. Keeping pipes from freezing or eliminating ice dams on drains and rooftops, R Trace is a self-regulating heating cable engineered to vary its heat output as the surrounding temperature changes; the colder it gets, the more heat is generated by the cable. Available in power densities of 3, 5 and 8 Watts per foot, all cables are UL Listed. Cables are available for 120 or 240 VAC applications. This self-regulating cable provides the right amount of heat when and where it is needed. Because of the self-regulating feature of this cable, it can be wrapped over itself (overlapped), if necessary, when installed on pipes, valves or flanges. ince this cable regulates its heat output with temperature, a thermostat may not be necessary for some freeze protection applications. pecially designed asy Heat kits provide the right hardware for properly installing R Trace selfregulating heating cables. ach connection kit contains detailed instructions for connecting the cable to power supplies and/or other heating cables.

4 Roof and Gutter Deicing substantial packaging works for both displaying and using the R Trace system. ach cable resides in a handy carry carton that conveniently dispenses the product on the distributor s shelf or at the job site. The kits easily hang from pegboard hooks or stand freely on shelves and countertops. Remember asy Heat s R Trace system when it s time to solve your cold weather problems. Cut-to-length design allows for easy field sizing and installation All power densities are available from the factory in cut-to-order lengths or in easy-to-use 250 ft. self dispensing reel boxes and 1000 ft. reels. pecially designed installation and connection kits ease installation. TNND COR BU WR HOW T WORK A special self-regulating core is at the center of the R Trace cable. This core is conductive and adjusts according to the surrounding temperatures. When it is cold, the cable s core has many conductive paths that generate enough heat to keep the water flowing in the pipe. As the surrounding temperature warms, there are fewer con ductive paths and less heat is generated. This self-regulating technology ensures the right amount of heat when and where it is needed.

5 How to Design a Roof and Gutter Deicing ystem TABL 1: Determination of Total Cable Requirements tem Foot of tem Comment For roof and gutter deicing applications, depending on voltage, use the R51J or R52J cables and related kits. 1. Multiply the roof edge length by the length factor from Table Add the appropriate cable amounts from Table 1 to the figure calculated in tep 1 to arrive at your total cable requirement. 3. Determine the number of circuits required by dividing the length of cable needed by the maximum single cable length in Table 3. Round that number up (for example, 2.4 to 3) to arrive at the total number of cable circuits required. 4. We recommend one clip for every three feet of cable you need. XAML: 100 of shingle roof edge with a 12ý overhang, one 12 downspout and one dormer with a perimeter of volts available, start-up temperature of 0 F. 1. hingle roof edge length (100 ) x spacing factor (1.9) = 190 ft. 2. Add 100 for gutter, 24 for downspout, and 20 for dormer to tep 1 = 334 total. 3. Divide total cable length (334 ) by maximum single cable length (142 ) = 2.4 (round to 3) 20A circuits.
