NOTE: Mounting height should not be less than 6' (1.8 m) if the heater is labeled as UL Listed and 8' (2.4 m) if the
heater is labeled as UL/CUL Listed. Indoor or well-protected environments will generally exceed average. Heaters can
provide less than average coverage in extremely cold/windy conditions.
GENERAL NOTES
1. INFRATECH QUARTZ TUBE ELECTRIC HEATERS are furnished with wall/ ceiling mount swivel brackets. These
brackets may be discarded when the heater is hung with chains or other special bracketing.
2. See sales literature and price list for full listing of models, descriptions, amperages, and voltages. At times, especially
when the mounting height must be quite low, an increased number of smaller heaters can help prevent overheating.
3. Heaters up to 15 AMPS can be used with a simple INF controller. This low cost controller, which is actually an infinite
switch, gently pulses the heat on and off.
4. For comfort heating, the best solution is to heat from two sides rather than from just one side. However, there are times
when this is not practical.
5. Areas covered are approximate dimensions and will vary depending on prevailing conditions and personal comfort levels.

Remove two screws from one end of trim and slide trim off opposite end to remove. Remove end reflectors. Open
element clips at each end of the heater and carefully install the quartz tube. Remove one nut from end of element. Install
wire by sliding high temperature ring terminal on to element screw and replace nut.
NOTE: Hold ceramic element firmly while tightening nut to prevent damage to element. Nut should be tightened snug. A
loose connection can cause the element to short or fail prematurely. Connect other side of element in like manner. Close
element clips over tube. Replace end reflectors.
Connect the High Temperature Stainless Ring Terminal on the wire ends
to the element studs located on both ends of the tube. Use a thin 11/32"
wrench to hold inside nut. Nuts must make a tight connection.
