How do I attach the PRO-Tect self regulating cable to the pipe?

Use plastic zip ties, aluminum or fiberglass tape, or pipe straps. Do NOT use vinyl electrical tape, masking tape or duct tape. Do NOT use metal wire or metal twist ties to attach the cable.

Once we installed the Self-Regulating cable and plugged it in, we noticed it was heating. Doesn't this self-regulate and not turn on until is is cold?

Self-regulating cable heats to the specified watts per linear foot when energized

What is the difference between WarmlyYours Ice Shield and WarmlyYours Pro-Tect self regulating cable?

Ice Shield is 120V or 240V and outputs 5W/ft, and is designed for roof and gutter deicing. PRO-Tect is 120V or 240V and outputs 5W/ft, 8W/ft, or 10W/ft, and is designed for pipe freeze protection.

Why am I getting a ground fault when the ground fault current is so low?

The GPT-230 displays a number of alarms, beside the ground fault it will also alarm for low current. If you have disconnected the load to trouble shoot a possible ground fault in the heater cable, then you probably have a Low Current Alarm and a very low default ground fault current reading. You can tell the difference by looking closely at the display, it will tell you what the alarm is for. If you want to clear the low current alarm so you can test the controller then go into the configuration menu and disable the Low Current Alarm. You will need to do this for each channel. Remember to re-enable the Low Current Alarms when you are done testing and ready to put the unit back into service.

Why does Zone 1 show zero milliamp while Zone 2 shows 3 dashes on the GPT 230?

The 3 dashes indicate that no ground fault current is being detected because that channel is not calling for heat.

Why is the low temp light on?

This would indicate that you have enabled the Low Temperature Alarm and that the current temperature the sensor is sensing is below the alarm setpoint. You can change the set point, wait for the heaters to warm the sensor, or disable the alarm.

Can heat tape start a fire?

Heat tape is electrical equipment: improper installation, damaged cable, or misuse can cause fire or electric shock. Select cable approved for your pipe and location, follow its layout and insulation requirements, provide the specified electrical protection, and inspect it before each cold season. Do not use damaged equipment or overlap cable unless the exact product instructions permit it.

Can Pipe Freeze Protection be used indoors and outdoors?

Yes, it can be used for both application types to prevent pipes from freezing and bursting during cold weather.

How long does it take for pipes to unfreeze if heat tape is installed?

Pipe heat tape is intended for freeze prevention, not as a guaranteed way to thaw an already frozen pipe. A frozen pipe may be damaged. Have the plumbing assessed and thawed safely by a qualified professional; never use an open flame. Before future cold weather, verify cable selection, thermostat placement, insulation, and electrical protection.

Can I extend the length of the sensor?

Yes, you can extend the sensor up to 2,000 ft. cable for enhanced installation options

Was this helpful? Yes No

Can I supply it with only one supply (jumper channels)?

Yes you can but you will need to increase the size (AWG) of the supply lines and circuit breaker to account for the increased load.

Was this helpful? Yes No

Can I use an RTD?

Yes, you can use a 3-wire RTD Sensor: Platinum, Alpha = 0.00385, ITS–90,100 ohms. Once it is installed you will need to configure the controller for it by navigating to the sensor type screen and changing it to RTD. The GPT-230 will allow you to use a different sensor on each channel or you can use one sensor for both channels. It is simply a matter of how you wish to configure it.

Can I use an extension cord to connect pipe heat / heat trace cable?

WarmlyYours does not recommend using an extension cord for permanent installations. Pipe heat should always be plugged directly into a receptacle or hardwired to the circuit that is powering it.

Was this helpful? Yes No

Can WarmlyYours pipe trace be used on pipe that will be buried in the ground?

No. It is not listed for this application, and it is not warrantied for use in direct burial or wet applications.

Was this helpful? Yes No

Can pipe heat be installed in walls?

No. Only install pipe heat (heat trace cable) in accessible locations. Do not install this self regulating cable in walls or any place where the cable is hidden. Do not run it through walls, ceilings, or floors. The cable must be installed 10“ away from combustible surfaces, such as wood, and it should not be embedded in insulation or roofing material.

Was this helpful? Yes No

For exterior: Should I wrap the vertical exterior plastic pipe (3/4 inch ) with the electric tape then install fiberglass tubular insulation over it to keep dirt off the tape?

Do not wrap self regulating cable around the pipe in a coiled or spiral fashion, and do not use electric tape to attach it. WarmlyYours recommends attaching the cable in a straight run and to use aluminum or fiberglass tape, pipe straps, or plastic zip ties to attach the cable. Then cover the assembly with fire-resistant insulation and assure it is waterproof. Place electrical heating cable WARNING labels every 10‘, and where the label will be clearly visible.
