Before installing
1. Open carton and remove heater at the place of installation.
2. Check nameplate volt and watt rating against your power supply
voltage and heating requirements of your installation. This name-
plate is located on one end of the heater.
MOUNTING
1. Framing: Fabricate structural support using angle iron or contin-
uous slot metal framing (manufactured by others). Dimension
framing per Table B and Figure 1 for your size panel.
2. Assembly: Position U-RP radiant panel on fabricated structural
support and attach using 1/2” diameter bolts of suitable length
(see Fig. 2).
3. Insulation: Where unusually high work temperatures are encoun-
tered, it may be desirable to insulate backs of heaters with high
temperature fibrous insulation. A suggested method of accom-
plishing this is indicated in Figure 2.
