  • Heaters greater than 240 Volts are for “Commercial Use Only. Risk of fire. Do not use as a residential or household heater.”
  • A means for disconnection of the appliance must be incorporated in accordance with the local wiring codes.
  • Do not use if the heating element is damaged or cracked.


This heater must be permanently installed and hard-wired by a licensed electrician in accordance with local electrical codes. Assembly procedure must be performed with no electrical power to unit.

  1. Check UL/CUL/CE label on heater for proper voltage.
  2. Follow supplied wiring instructions. (See wiring instructions below)
  3. Heater must be mounted with reflector angled down.
  4. All electrical connections must be in compliance with the National Electric Code (NEC) and local codes for outdoor wiring.
  5. Use only wiring components UL/CUL/CE listed for outdoor use with IPX4 minimum rating.


The heater is drilled and threaded for standard 1/2″ conduit fittings. The installing electrician will need to provide the appropriate rigid metallic, flexible or liquid-tight conduit for the installation location.

  • Observe local electrical code regulations.
  • Remove cover plate from junction box.
  • Attach conduit.
  • Use only copper wire suitable for 90°C.
  • Replace cover plate.


These models may be chain or bracket mounted to any ceiling or horizontal surface. Installation must be such that 18″ (45.7cm) minimum clearance is maintained around the heater on all four sides and 36″ (91.4cm) directly in front. A minimum of 6″ (15.24cm) of clearance provided by mounting brackets is required behind the plane of the face. Heater can be hung using chains or custom brackets. Heater must be level, but can be rotated around its horizontal axis.

Heater must be installed with the quartz tube horizontally level. For maximum tube life, use a carpenter’s level tool to fi nd the optimum level position for the heater’s body. It’s important to always maintain the minimum clearances from the heater body to any combustible materials.


Disconnect the power at the breaker. Remove the grill by grasping it in the middle, flex grill up, and lift it off. Unscrew and remove both end reflectors. Unhook element clips at each end of the heater and remove nuts from end of element to remove the existing quartz tube. Carefully install the new element. Remove one nut from end of the new element. Install wire by sliding high-temperature ring terminal onto element screw and replace nut. Use a thin 11/32″ wrench to hold inside nut. Nuts must make a tight connection. Close element clips over tube, reinstall end reflectors, then snap protective grill back in place.

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.

NOTE: Mounting height should not be less than 6′ (1.8m) if the heater is labeled as UL Listed and 8′ (2.4m) if the heater is labeled as CUL Listed. Indoor or well-protected environments will generally exceed average. Heaters can provide less than average coverage in extremely cold/windy conditions.


  • INFRATECH QUARTZ TUBE ELECTRIC HEATERS are furnished with multi-position wall/ceiling mount brackets.
  • See sales literature and price list for full listing of models, descriptions, amperages, and voltages. At times, especially when the mounting height might be quite low, an increased number of smaller heaters can help prevent overheating.
  • Heaters up to 15 AMPS can be controlled with a simple INF Input Regulator. This low cost controller, which is actually an infinite switch, gently pulses the heat on and off at regular intervals when not on full power.
  • Dual Element Heaters can be wired with our Duplex/Stack Switch, which enables the ability to turn on and off each element independently, providing for half power/full power capabilities.
  • For ideal comfort heat, the best solution is to heat from two sides rather than from just one side. However, there are times when this is not practical.
  • Coverage areas are approximate dimensions and will vary depending on prevailing and personal comfort levels.
  • Indoor or well-protected environments will generally exceed average (see charts). Heaters can provide less than average coverage in extremely cold/windy conditions.


  • Before performing any maintenance, power must be disconnected and the heater cool to touch.
  • Heater housing, reflectors, and heating element can be rinsed with a hose or wiped down with isopropyl alcohol, acetone, or glass cleaner. Use a clean, scratch-free rag or paper towel. Any oxidation, surface rust, or discoloration can be removed with a stainless steel cleaner or metal polish on the bare metal surface.
  • Make sure all water, solvents, or cleaners are removed and the heater is dry before reconnecting the power.



Unless heaters are installed over 12′ (3.7m) high, it is generally recommended that all radiant heaters be mounted on an angle to assure that radiant warmth is distributed from the sides rather than straight down on the heads and shoulders of the people being warmed.
