Ducoterra Radiant Heating Panel Installation Manual
1. Introduction
Your new radiant heating panels are designed to heat living and working spaces rapidly and efficiently
by radiant heating. Like the sun, these panels will create a warm environment rapidly for all objects
within line of sight of the panel surface. They are designed to be surface mounted on ceilings or for
installation in a T-bar grid.
2. Installation Layout Guidelines
In a standard 8’ ceiling room, these heating panels will cover approximately 10 times the floor square
footage as panel size (e.g. a 2x4 panel will cover approximately 80 square feet of floor space). They
may be installed at zero clearance to adjoining walls and adjacent panels, but optimal coverage is
obtained by spacing the panels to cover the floor space efficiently.
As maximum panel efficiency is obtained within at 45 degree angle of the panels, spacing panels 2’ off
walls and approximately 4’ from other panels will generally cover a room sufficiently. Panels may need
to be positioned differently depending on specific room configurations, insulation, heating
requirements, and other factors.
3. Environment Insulation Requirements
For proper functionality, the heated space should be insulated appropriately. Optimal panel operation
is achieved if walls and ceilings are insulated according to ASHRAE 189 standards in accordance with
your local climate zone. Heating panel connection box must not be covered with insulation material
after installation. Heating panel itself has an insulation value of R-5.
4. Wiring Requirements and Guidelines
Heating panel has two 10” 12 AWG leads for connecting to standard #12 power supply with wirenuts
inside the attached connection box. See appropriate wiring diagrams for details (Fig 3).
WARNING: To avoid the risk of electrical shock, personal injury or death, disconnect all electrical
power before installing or performing maintenance on this panel.
The wiring, installation, and electrical hookup of this panel must conform to local and national codes.
Total wattage of heating panels per circuit must not exceed 80% of circuit capacity. Panels should be
installed in conjunction with a line voltage or 24V thermostat. Thermostats utilizing IR readings are
preferred. Measure voltage and branch circuit amperage to determine wattage and panel circuit load.
CAUTION: Wiring procedures and connections shall be in accordance with the national and
local codes having jurisdiction
WARNING: Panel must NOT be wired to higher voltage than label voltage

5. Surface Mounting Guidelines
WARNING: DO NOT puncture panel with screws, nails, or any other device. Panel must be mounted
through provide mounting holes.
Panels may be mounted to joists, wood, or other penetrable surfaces using appropriate hardware. The
mounting holes are designed to accommodate #8 –2” pan head screws. Joint between panel and
mounting surface should be sealed with heat resistant (rated to a minimum of 100C) caulking for
maximum performance.

IMPORTANT INSTRUCTIONS
When using electrical appliances, basic precautions should always be followed to reduce the risk of fire,
electric shock, and injury to persons, including the following:
1) Read all instructions before installing and using this heater.
2) Extreme caution is necessary when any heater is used by or near children or invalids and whenever
the heater is left operating and unattended.
3) Do not operate any heater after it malfunctions. Disconnect power at service panel and have heater
inspected by a reputable electrician before reusing.
4) Do not use outdoors.
5) To disconnect heater, turn controls to off, and turn off power to heater circuit at main disconnect
panel.
6) A heater has hot and arcing or sparking parts inside. Do not use it in areas where gasoline, paint, or
flammable vapors or liquids are used or stored.
7) Use this heater only as described in this manual. Any other use not recommended by the
manufacturer may cause fire, electric shock, or injury to persons.
8) SAVE THESE INSTRUCTIONS

SURFACE MOUNTING INSTALLATION
Wiring procedures and connections shall be in accordance with the national and local codes having
jurisdiction.
To reduce the risk of fire, do not store or use gasoline or other flammable vapors and liquids in the
vicinity of the heater.
1. Cut appropriate sized hole for panel connection box and insure clearance from insulating material.
2. Attach connection box to back of panel using provided hardware.
3. Attach power supply leads to the panel leads in connection box.
4. Position on ceiling in desired mounting location.
5. Attach panel to ceiling using provided mounting hardware. Insert plastic caps to close mounting holes.

Testing Installation
After installation, the heating circuit should be checked to ensure all panels have been installed properly and
are functioning normally. With power available, measure the branch load with an amp meter. The amp meter
value should agree with calculated load –if not, recheck the installation. A physical check of operation can
also be made –with power to the panels, they should be warm to the touch and prolonged contact should be
uncomfortable.
If no power is available to test the circuit, the use of an ohmmeter is required. Measure the resistance of the
load circuit, isolated from other circuits. The measured resistance of the heating circuit should match the
calculated resistance. The resistance can be calculated with the following formula:
𝑅𝑒𝑠𝑖𝑠𝑡𝑎𝑛𝑐𝑒 =
𝑉𝑜𝑙𝑡𝑠 ∗ 𝑉𝑜𝑙𝑡𝑠
𝑊𝑎𝑡𝑡𝑠

Heating Panel Operation
Ensure panels have been properly installed prior to operation. Radiant heat ceiling panels function best in a
zone heating configuration. Use a programmable thermostat to apply appropriate setbacks to spaces that are
unoccupied. Optimal comfort with a radiant system is typically obtained at air temperatures of around 60-62F.
It is recommended that the panels are dusted & cleaned with a damp cloth every 6 months. Do not use harsh
cleaners or abrasives or damage to panel surface may result. Do not lubricate. Make sure to disconnect power
to panels at breaker box before cleaning, and allow panel to reach room temperature.
Heater may be stored when not in use in a cool, dry location.
Panel contains no user serviceable parts and opening the heating unit will void the warranty.

Heating Panel Maintenance
Ducoterra heating panels require no maintenance and carry a 20 year warranty. An occasional dusting & wipe
down with a damp cloth every 6 months to maintain appearances is all that is necessary. Do not use harsh
cleaners or abrasives or damage to panel surface may result. Make sure to disconnect power to panels at
breaker box before cleaning, and allow panel to reach room temperature. If your panel ceases to operate at
any time during the warranty period, contact Ducoterra to obtain a replacement panel at no charge
(installation costs not covered). Panels contain no user serviceable parts and opening the heating unit will
void the warranty.
