These are high performance products designed to work in cold and harsh environments. Retro-Line products are uniquely adaptable to many types of applications. System requirements will vary a great deal in accordance to ground conditions.
It is recommended that the Retro-Line installation be made by a qualified tradesperson. This will ensure that optimum performance is achieved in each installation. Variables include: retro-fitting of existing pipes – shallow buried in ground or rocky geography especially where thermostatic control is not possible – free air installations above ground and insulated – with or without thermostatic control.
Thermostatic controls and timers are optional but should be considered for every application for further energy savings if applicable. The use of insulation should also be considered for cold weather reliability and energy efficiency.
A. This heating cable set shall be installed in accordance with the National Electrical Code (USA) or the Canadian Electrical Code.
B. It is imperative that for all installations where the pipes are exposed to the outside ambient temperature that weatherproof insulation be used. (Wall thickness ½ inch minimum). Heat-Line offers closed cell foam types, foil/ air bubble type and others. Other types of weather-proof insulations may also be used.
C. Retro-Line can be used even when there is no water in the pipe. Retro-Line WILL NOT melt your water pipe. In the event of power failure your system may freeze. The system will however re-energize immediately following power restoration and will thaw out again. In most cases no damage to pipes will be encountered.
D. When installing in metal pipes, always be sure that there are no sharp edges and pipes are properly reemed smooth
Retro-Line is a technically advanced product. Handle it with proper care and be sure not to damage the outer sheath or jacket of the cable.

· Short Retro-Line systems may be pushed in without the use of a fish tape or rope. Longer systems may require the use of a fish tape or other installation method. For long systems a vacuum can be used to draw a sponge “”mouse” through the pipe with a 1/8″ mason line attached. These sponges can be hand made or purchased from Heat-Line. Extra long systems may require “cutting in” a coupling or series of couplings to provide access points to pull in the Retro-Line. When this is required it is important to use a Philmac® coupling furnished by Heat-Line.
· A 6 foot leader is provided with all Retro-Line systems over 90 feet. This leader is your point of attachment for pulling in the Retro-Line. If the leader is not required, remove it and simply push in the Retro-Line into the pipe.
· A non-toxic, water based (potable) lubricant can be used to make cable insertion or pushing of long lengths easier.
NOTE: Retro-Line systems in reasonably straight runs up to 150 feet can most often be pushed all the way in without pulling. The Retro-Line leader is only provided as an aid to pulling. It is unable to withstand extremely hard pulls and will break if over stressed. Heat-Line will not be responsible should this occur.

Retro-Line Installation
Control Devices and Insulation Installation
Control devices are not required to operate the heating cable system. They can be added for energy efficiency.
Thermostats are used to duty cycle the system in an on/off operation saving power consumption and maintain a certain pipe temperature. A sensor lead must be placed on the coldest section of pipe.
Timers are used to duty cycle the system in an on/off operation based on preset time intervals to save on power consumption.
Insulation is recommended for all new pipe installations, even where the pipe is to be buried.
For existing pipe applications, insulation is only required where the pipe is exposed to ambient outdoor temperatures, and/or where the pipe is above the ground. Insulation aids in heat retention making the heating cable more energy efficient and providing cold weather reliability.

Weighting/Ballasting Water Pipes in Lakes

Retro-Line Installation

Note: There are various methods of weighting pipes down, but we have noted the “Pre-mixed Concrete Bag Method” to be a great option.
A simple and excellent alternative to stones, blocks and other methods.
Rationale: The pre-mix concrete bags are generally 66 lbs and are relatively easy to handle. The bags should be placed over pipe to hold it down.

IMPORTANT
CONCRETE PRODUCTS ARE ENVIRONMENTALLY SAFE, HOWEVER, WE SUGGEST YOU CHECK WITH YOUR LOCAL AUTHORITIES BEFORE INSTALLATION. Pre-mixed concrete is packaged in plastic and paper. We recommend paper as it will naturally deteriorate and break down. Concrete bags are placed or dropped “dry” over the pipes allowing water to seep in and cure in place. When in water, straddle the pipe and drop the dry bag onto the pipe. Do not try to move the bag once dropped as it will immediately break down.

Side View

When water recedes from the high water mark to low water mark, pipe becomes exposed to atmosphere and can freeze if uninsulated.
Insulation is bouyant and will float up towards the surface when water rises in the spring. 66 lb pre-mixed concrete bags will hold the pipe on the bottom when at high level.
