ATTENTION
Mount a copy of these instructions adjacent to heater
and retain a copy for future reference.
These heaters MUST be installed and serviced ONLY
by trained and qualified gas installation and service
personnel. The installing contractor must be familiar
with all the various requirements and is responsible for
installing each heater in compliance with these
instructions and all applicable codes of all authorities
having jurisdiction, local, state, provincial and national.
GENERAL INFORMATION
These heaters are CSA International Design Certified
and manufactured for either indoor or outdoor installation in
compliance with American National Standard for Gas-Fired
Low-Intensity Infrared Heaters ANSI Z83.20/CSA 2.34-latest
edition. An Outdoor Kit is required for outdoor use. If you
have any questions call factory before attempting
installation. These heaters are approved for commercial
and industrial installation only.
A limited number of excerpts from various standards
and codes are outlined in the following instructions.
UL LISTING
These heaters are design certified by CSA International
for compliance with ANSI Standard Z83.20-latest edition.
CSA International is the appropriate agency as they
specialize in gas appliances while Underwriters Laboratories
(UL) specialize in electric appliances. If UL were to design
certify the heaters, it would be to the same ANSI Standard.
Certification by UL is not required, as it would be redundant.
LOCAL APPROVALS
These heaters have local approvals by such governing
bodies as: New York City (A Series: MEA 232-95-E Vol. 2;
B and C Series MEA 417-86-E Vol. 5; MB Series MEA 233-

Minneapolis, Minnesota (#05444); the Commonwealth of
Massachusetts; and the State of Nebraska.
INSTALLATION CODES
All installations must be in accordance with local codes
and the National Fuel Gas Code, ANSI Z223.1 / NFPA 54-
latest edition. In locations used for the storage of
combustible materials, signs shall be posted to specify the
maximum permissible stacking height to maintain required
clearances from the heater to the combustibles. Where
unvented infrared heaters are used, natural or mechanical
means shall be provided to supply and exhaust [combustion
and ventilation air at a rate of] at least [4 CFM per 1000
BTUH] 4 ft
/min/1000 Btu/hr (0.38m
/min/kW) input of
installed heaters. Exhaust openings for removing flue
products shall be above the level of the heaters.
The heater, when installed, must be electrically grounded
in accordance with the National Electric Code, ANSI/NFPA
70-latest edition. All electrical work must conform to the
National Electrical Code ANSI / NFPA 70-latest edition. The
installation must meet the requirements of the Occupational
Safety and Health Act (OSHA) which requires OSHA
approved service and safety access to the systems after
they are installed.
AIRCRAFT HANGARS
These overhead heaters are suitable for use in aircraft
hangars when installed in accordance with the Standard on

measurement shall be made from the wing or engine
enclosure, whichever is higher from the floor, to the bottom
of the heater. In shops, offices, and other sections of
aircraft hangars communicating with aircraft storage or
servicing areas, the bottom of the heaters shall be installed
not less than 2.4 m (8 ft) above the floor. In all hangars,
suspended or elevated heaters shall be located in spaces
where they shall not be subject to injury by aircraft, cranes,
movable scaffolding, or other objects. Provisions shall be
made to ensure accessibility to suspended heaters for
recurrent maintenance purposes.
REPAIR GARAGES
These overhead heaters are suitable for use in repair
garages when installed in accordance with the Code for
Motor Fuel Dispensing Facilities and Repair Garages, NFPA

appliances using gas fuel listed for use in garages shall be
permitted to be installed in lubrication rooms, service rooms,
or fuel dispensing areas where Class I liquids are dispensed
or transferred, provided the equipment is installed at least
2.4 m (8 ft) above the floor.
! WARNING !
An overhead heater should be installed so that the

assembly or 500 mm (18 in.) above the floor.
MATERIAL SAFETY DATA SHEETS (MSDS)
These heaters comply with the US Superfund
Amendments and Reauthorization ACT (SARA) Title III. No
Material Safety Data Sheets are required.
GAS/RATING CONVERSION OF INSTALLED HEATER
Conversions of gas type and BTUH ratings are possible.
Identify model and serial numbers from the serial plate
located on the exterior of the burner. Identify the length of
radiant tubing. Review the BASIC SYSTEM
CONFIGURATIONS section to determine if system
components in addition to burner parts are needed to
convert the heater. Contact the factory for approved parts
and instructions.
