Operating Instructions and Owner’s Manual
Supply gas piping to the unit should conform to the local and national
requirements for type and volume of gas handled and pressure drop
allowed in the line. Avoid pipe sizes smaller than 1/2”.
NOTICE:
It is recommended to use a flexible connector to avoid
vibration transmissions.
Electrical:
The heater, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes, with the
National Electrical Code, NFPA 70, or the Canadian Electrical Code,
CSA C22.1. Under no circumstances is the electrical supply line to
provide any assistance in the suspension of the heater.
Ventilation:
This heater must be installed in accordance with the requirements set
forth in this manual and with the NFPA 54/ANSI Z223.1 National Fuel
Gas Code (latest edition).
The units comply or are certified by one or more of the following
organizations or standards:
•
CSA International Requirement (CSA 2.37).
•
American National Standards Institute (ANSI Z83.26 and ANSI
Z83.19)

Sprinkler Heads:
Fire sprinkler heads must be located at an appropriate distance from
the heater to avoid accidental discharge of the fire suppression system.
This distance may exceed the published clearances to combustibles.
Certain applications will require the use of a higher classification of
sprinkler heads or relocation of the heaters. Consult the manufacturer
of the sprinkler heads and NFPA 13 for more information.
SAFETY LABELS AND THEIR LOCATIONS
It is important to provide warnings to alert individuals to potential
hazards and safety actions. Safety warning labels must be maintained
on the infrared heater. In locations used for the storage of combustible
materials, signs must be posted to specify the maximum permissible
stacking height to maintain the required clearances from the heater
to combustibles. Signs must either be posted adjacent to the heater
device or, in the absence of such control(s), in a prominent location.
