2.0 Installation • Design
Read and understand, the installation, operating and maintenance instructions
thoroughly before installing or servicing this equipment.
Design
To ensure a safe, properly designed heating system, a layout should be developed for the correct
placement of the infrared heater(s).
Aside from safety factors such as clearance to combustibles (see Chart 1.1 on page 6), you should also
take into consideration the environment (e.g., cold/drafty, average, protected), heat coverage (sq. ft.)
needed, heater centers, the distance behind a person or work station(s). Also, the effective infrared
surface temperature of a person or object may be diminished with wind above 5 mph. Wind barrier(s)
may be required. Most importantly, clearance to combustibles must always be maintained! Refer to
hazards on page 5.
When positioning the heaters, keep in mind combustible materials, lights, sprinkler heads, overhead
doors, storage area with stacked materials, gas and electrical lines, parked vehicles, cranes, etc. Refer to
Page 6 for minimum clearance to verify that a safe installation exists.
This installation manual, along with national, state, provincial and local codes, address these issues. It is
critical that you read, understand and follow all guidelines and instructions. Always inspect and evaluate
the mounting conditions, application, and wiring.
When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehydes, etc.)
can evaporate and/or degrade. This may result in odors or fumes being emitted into the environment. To
correct this problem, clean the area and/or introduce additional ventilation. Heaters installed and serviced
in accordance with the installation manual do not emit foul odors into the environment.
IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater to avoid
an inadvertent discharge. This distance may exceed the published clearance to combustibles. Certain
applications may require the use of high temperature sprinkler heads or relocation of the heaters.
Fire sprinkler systems containing propylene glycol, antifreeze or other potentially flammable substances
shall not be used in conjunction with this heater without careful consideration for and avoidance of
inadvertent discharge hazards. For further information consult NFPA 13. Always observe applicable state
and local codes.

One-Year Limited Warranty. Detroit Radiant Products Company (hereinafter referred to as the Company)
warrants to the original purchaser or original user that all Detroit Radiant Gas Infrared Heaters sold by it and all
parts thereof are free from defects in material or workmanship under normal use and service. The Company’s sole
obligation under this warranty shall be limited to furnishing replacement parts, F.O.B. Warren, Michigan, for 12
months from the date of initial installation of the heater, but not to exceed 18 months from the date of shipment by
the Company of the heaters, for any parts which the Company’s examination shall disclose to its satisfaction to be
defective. Defective parts are to be returned to the Company, transportation charges prepaid.
General Conditions. The warranties set out in this certificate are the exclusive remedy of the original owner or
user in lieu of all other warranties written, oral or implied (including any warranty of merchantability or fitness for
the purpose) and all other obligations or liabilities on the part of the Company, and the Company neither assumes
nor authorizes any person to assume for it any other obligation or liabilities on the part of the Company, and the
Company neither assumes nor authorizes any person to assume for it any other obligation or liability in connection
with the sale, installation or use of the heater or any parts thereof.
The Company will not be responsible for labor charges for the analysis of a defective condition in the heater
or for the installation of replacement parts. The warranties provided herein will not apply if the input of the
heater exceeds the rated input at time of manufacturing or if the heater in the judgment of the Company has
been subjected to misuse, excessive dust, improper conversion, negligence, accident, corrosive atmospheres,
excessive thermal shock, excessive vibration, physical damage to the heater, alterations by unauthorized service
personnel, operation contrary to the Company’s instructions or if the serial number has been altered, defaced, or
removed. The Company shall not be liable for any default or delay in the performance of these warranties caused
by contingency beyond its control, including war, government restriction or restraints, strikes, fire, flood, short or
reduced supply of raw materials, or parts.
The warranties herein shall be null and void if the heater is not installed by a competent heating contractor and/
or if the heater is not installed according to Company instructions, normal industry practices and/or if the heater
is not maintained and repaired according to Company’s instructions. Normal product degradation and wear (rust,
oxidation, etc.) does not constitute a material defect and applicable warranty claim.
Written permission is required for the return of any parts or equipment and any such return must be made on the
basis of transportation charges prepaid. Shipment may be refused unless prior written permission is obtained and
goods returned prepaid.
This warranty applies only within the United States.
