APPROVALS

-WS

FIRE AND SHOCK HAZARD. This product is an electrical device

that must be installed correctly to ensure proper operation and to

prevent shock or fire. Read these important warnings and carefully

follow all the installation instructions.

• 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 Pentair Thermal Building

Solutions agency certifications, and 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.

• For pipe freeze protection applications, use only fire-resistant

insulation materials such as preformed foam or fiberglass.

• Do not damage the heating cable and power cord or plug.

Remove any damaged cables from service immediately.

• Do not use any wire or metal clamps to attach the cable to the

pipe. Use tape (1/2 inch wide to 1 inch wide) or plastic cable ties.

• Do not install the heating cable underneath any roof covering

for roof and gutter de-icing.

• Leave these installation instructions with the user for future

reference.

Pipe Freeze Protection General requirements for pipe freeze protection: General instructions: • FrostGuard heating cables may be used on metal and plastic water pipes but not on flexible vinyl tubing (such as garden hoses). • FrostGuard heating cables are not intended for use inside any pipes, for freeze protection of liquids other than water, or for use in classified hazardous locations. • Install with a minimum of 1/2” fire-resistant, waterproof thermal insulation.

Strain relief Cord label Pipe label Figure 3. Insulation Figure 4. Strain relief 4. Install thermal insulation. • A reliable FrostGuard system depends on properly installed and dry, weatherproofed thermal insulation. • Ensure that at least 1/2” of preformed foam or equivalent thermal insulation is used and that all piping, including valves, joints, and wall penetrations, has been fully insulated as shown in Figure 3. • For protection to -20°F (-29°C), use 1” thick insulation.

Roof & Gutter De-icing Note: Route and secure the heating cable to avoid possible mechanical damage, such as from ladders, etc. General requirements for roof & gutter de-icing: • FrostGuard is designed to remove melt water, not accumulated snow. • FrostGuard heating cable will not keep snow or ice from falling off the roof. Snow fences or snow guards should be used to eliminate snow movement.

FrostGuard 120 V (FG1) heating cable selection for roof & gutter de-icing 1. Calculate the heating cable length. Find the number of feet of heating cable needed per foot of roof edge in Table 3. Then, calculate the amount of total heating cable length you need using the following formula: Table 3. Typical spacing and layout measurements Length = A + B + C + D A Roof edge length (ft) x Length of cable per foot of roof edge (ft) B Roof extension: Roof edge (ft) x 0.

1/3 2/3 Figure 7. Standard roof clip attachments • Extend the top of each heating cable loop beyond where the wall joins the roof. • Trace two-thirds of the way up each valley with a double run of heating cable as shown in Figure 8. • Use H913/H914 roof clips to route heating cable into and out of the gutter in such a way as to prevent abrasion to the cable. Protect all cable that protrudes past the lower opening of the downspout.

Heating cable testing and maintenance Make sure that gutter and downspouts are free of leaves and other debris prior to the winter season. Using a 2500-Vdc megohmmeter (2500 Vdc minimum), unplug the FrostGuard and test the unit by checking the insulation resistance between the flat blade and the ground pin in the plug. Minimum reading should be 1000 megohms regardless of FrostGuard length. Record the original values for each circuit.
