for Infrared Radiant Heaters for Industrial and/or Commercial Applications
CERAMIC
HEATERS: DK Series |
Gas-fired infrared space heaters
shall be furnished and installed in accordance with governing codes
and as shown per building drawing(s) as described below:
Heaters shall be SPACE-RAY DK series
ceramic heaters, model number DK_________, rated at _____________ Btu/hr,
as manufactured by Gas-Fired Products, Inc., Charlotte, North Carolina.
Heaters shall be equipped with a 24-volt direct spark ignition system
with 100% gas shutoff.
Heaters shall be made of aluminized
steel body construction and shall consist of multiple burner heads.
Heaters shall utilize special honeycomb tile design for increased radiant
ouput.
As an option, heaters may be equipped
with an Incoloy 800 reverberatory screen. The reverberatory screen will
increase the overall emissivity of the radiant surface with a blackbody
radiation effect and will act as a protective safety screen in the unlikely
event that the ceramic tile assembly is broken by an outside force.
The heater's tile temperature can vary from 1650ºF to 1800ºF
and the tiles shall withstand thermal shock when water quenched.
Heaters shall operate satisfactorily
in any position from horizontal to thirty-five (35º) degrees from
horizontal. Heaters shall be design certified by C.S.A. to American
National Standard Z83.19-latest edition/CSA Standard 2.35-latest edition.
The manufacturer shall provide a written limited warranty of five (5)
years covering the emitter tiles and a limited warranty of one (1) year
for all components utilized in the heater's control assembly.
