SRK00 Pipe Connection Kit

DESCRIPTION:

SR self-regulating heating cables

are designed for a variety of pipe

freeze protection as well as roof

and gutter deicing applications.

The heat output (wattage)

increases and decreases based on

the temperature, so the cable

adjusts automatically to varying

climate conditions. This unique

feature ensures maximum energy

efficiency by increasing the heat

output only when it is needed. No

thermostat is required.

DESCRIPTION The SRK00 hard wire power connection kit is to be used with King SR self regulating heating cables only. The kits are not approved to be used with other brands of heating cable. The kit contains enough material for making one hard wire power connection and one end seal. King SR cables are approved for both pipe freeze protection and roof and gutter deicing applications.

SR Heating Cable Selection and Design Use table 1 to select the heating cable size for insulated metal pipes and use table 2 to select heating cables for insulated plastic pipes. Read across the table to find the pipe size, then drop down the column to the row corresponding to the lowest design air temperature column for the application and chose the thickness of the insulation that will be used. The cell that intersects will give the power (watts/ft.

Circuit Breaker Protection and Cable Length Design for Pipe Freeze Protection Table 3: Maximum Single Cable Length The maximum length of a single cable run is noted in Table 3 and cannot be exceeded. If the application requires a longer cable run, then multiple cables and additional power circuits must be used. When using 240 volt SR cable on 208, 220 or 277 volt applications, the power output (wattage) must be adjusted.

Install heating cable end seals, splices, tees, and power connection prior to energizing cable. 2. Use only the SR00 power connection kit, SRK10 splice and tee kit, SRK08 GFEP power connection kit and SRK 12 end seal kit. STEP 5: CHECK FOR PROPER INSTALLATION 1.

SR Heating Cable Design for Roof and Gutter Applications GENERAL INFORMATION 1. SR cable is designed to remove ice, not accumulated snow. 2. SR cable will not keep snow or ice from falling off of the roof. Snow fences or snow guards should be used to eliminate snow movement. 3. SR heating cables may be used on: - Roofs made from all types of roofing materials, such as shake, shingle, rubber, tar, wood, metal, and plastic. - Gutters made from standard materials, such as metal and plastic.

Figure 5: Roof Clip, Standard Shake Roof Figure 6: Roof Clip, Metal Roof STEP 2 (continued) 4. One SRK13 kit contains 25 roof clips for approximately 17 linear feet of the roof edge. 5. Roof clips may be attached to a shake or shingle roof using nails or screws. Roof clips may be attached to a metal roof using nails, screws, or adhesive. Reseal the nail or screw holes if necessary before installing heating cable in the clips.

STEP 5: TERMINATING DOWNSPOUTS 1. The preferred method of installation is to run the heating cable into the downspouts, ending the cable in a loop at the bottom of the downspout and then run the cable back up the downspout into the gutter . This way there is no end seal in the downspout. For single cable runs in downspouts with an end seal use a tie wrap to fasten it as shown in Figure 9. Do not leave the end of the heating cable pointing down at the end of the downspout, double back as shown.
