PREPARE THE HEATING PANELS

Heating panels should be prepared for each room at one time prior to starting installation.

1. The panels are cut to length using a knife or scissors to fit the bays under the heatable area.

2. Connectors are then attached to one end of each heating panel set. To attach: Center a connector over one end of each bus bar, pressing them in place with finger pressure, and then crimp each connector in place using the flat portion of the crimping tool as shown in the following figure.

3. Insulate the other end of each bus bar. Place a length of electrical tape over the exposed end of each bus bar opposite the electrical connector.

ATTACHING HEATING PANEL SETS

1. Heating panel sets are aligned with the joists to which they will be attached.

2. The panels are set in place with nails or staples, leaving at least a 6" clearance to walls or partitions at the connector end for wiring and final assembly. Nails or staples are placed as close to the perforated bending line as possible, maintaining a 2" space between the perforation and the top edge of the joist. Nails or staples should be placed at least once every 12" along each side of the heating panel set.

3. The heating panel are then folded so that they run level between the two joists. The other side of the panels are then nailed or stapled to the other floor joist into position.

NOTE
Heating panels should be recessed 2" from the bottom of the floor to create an air gap above the heating panels. This air gap will maximize the performance of the RetroHeat system.
