& GUTTER DEICING

1. Calculate the length of the roof edge, eave
overhang, gutter and downspout to determine
the length of the cable you need.

2. Attach the heating cable to the roof with roof clips,
cable ties and downspout hangers.

3. Run the heating cable along gutters and
downspouts using a hanger bracket on the
gutter/downspout transition (or two hanger
brackets if looping)

4. Mark the installation with labels provided
on the outlet cover and at the fuse or circuit
breaker panel.

5. Plug FrostGuard into a ground-fault protected
3-prong electrical outlet.

PREVENT ICE DAMS
AND FROZEN GUTTERS

WHEN WINTER BRINGS
SNOW AND ICE

Ice buildup, icicles and standing water from melting
snow can cause severe damage to your roof and
gutter, leading to costly structural damage or injury.

WHAT IS FROSTGUARD?

Raychem FrostGuard is an energy-efficient
preassembled heating cable used to protect roofs
and gutters from the harm that winter brings.

FrostGuard is available as a Plug-n-Play Kit (120 V)
and its self-regulating heating cable delivers just the
heat that is needed.

SELFREGULATING
TECHNOLOGY

‘High’ Temperature Few Conductive Paths
Less Heat Produced

‘Mid’ Temperature Few Conductive Paths
Self Regulating In Action

‘Low’ Temperature Many Conductive Paths
More Heat Produced

The simple Plug-n-Play system is ideal for
residential and small commercial buildings and
requires no specialist electrical knowledge.
Simply fix to the roof, gutters and downspouts and
plug into a ground-fault protected electrical socket.
It is that simple.

PRODUCT OVERVIEW

Raychem FrostGuard preassembled self-regulating heating
cables are designed for residential and commercial metal
and plastic pipe freeze protection and roof and gutter de­icing applications. 120 V FrostGuard cables are available in
6, 12, 18, 24, 36, 50, 75 and 100 foot lengths, and each comes
assembled with a 6-ft power cord and 3-prong, grounded,
lighted plug to show the system is on. 120 V FrostGuard
cables are ideal for smaller jobs such as roof and gutter de­icing on porches and overhangs, as well as for pipe freeze
protection on metal or plastic pipes up to 2-½ inches in
diameter.

240 V FrostGuard cables are available in 6, 12, 18, and 24
foot lengths and each come assembled with a 6-ft power
cord for terminating in a junction box. Due to their short
lengths, 240 V FrostGuard cables are designed only for pipe
freeze protection applications on pipes up to 2-½ inches in
diameter.

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, 30-mA equipment or 5-mA personnel ground-fault protection
must be used on each FrostGuard heating cable branch circuit. Arcing may not
be stopped by conventional circuit protection.

in table to the right. Then, calculate
the amount of total heating cable

formula:

Length = A + B + C + D

A Roof edge length (ft) x Length of

cable per foot of roof edge (ft)

B Roof edge (ft) x 0.5*
C Total gutter length (ft)
D Total downspout length (ft)

the heating cable to extend into
the gutter to provide a continuous
drain path, or where no gutters are

Note: Pentair Thermal Building Solutions recommends a gutter and downspouts to
provide a continuous path for melted water.

• If downspout is in the middle of the run, loop the FrostGuard down and back up.
Double the length of the downspout for determining the length of FrostGuard to
install.

• For valleys, run the heating cable two thirds of the way up and down the valley.

• For gutters 5-6 inches wide, use 2 runs of heating cable.

• For gutters wider than 6 inches contact Pentair Thermal Building Solutions,
