Part 2 — Product

2.01 EQUIPMENT (STANDARD)

A. General:

Factory assembled, single-piece infrared radiant heating unit for overhead mounted patio, space

or area heating application. Supplied with the heater will be all necessary factory installed wiring,

piping, and controls required prior to field installation and start-up.

B. Heater Enclosure Construction:

a. Exterior sheet metal enclosure components, and all interior sheet metal components

exposed to direct heat from the burner will be constructed of 409 grade stainless steel.

b. An interior sheet metal divider in the control compartment, and control mounting bracket

will be constructed of high grade aluminized steel.

c. All exposed surfaces of exterior sheet metal components will have a coating of high

temperature flat black emissive coating.

C. Burner Construction and Emitting Surface:

1. General:

a. Burner body will be constructed of high grade aluminized steel

b. The radiant surface will be comprised of a panel of porous ceramic burner tiles with

indentation surface technology creating 372 indentations in the tile radiating surface that

increases the emitting surface area by 50%.

c. Ceramic tiles will have a homologous grid of approximately 3400 needled perforations

that differ not more than +/- 0.001 inch (0.03 mm) in diameter to create a homogeneous

radiant surface.

c. The thermostat will incorporate automatic temperature setback of 9F° (5C°) during an unoccupied condition. A photoconductive cell will be used to sense occupancy within the heater zone by sensing illumination. Resumption of the occupied state illumination level will return thermostat temperature control to full comfort setting. A switching mechanism will allow calibration of the photoconductive cell to the base illumination level for occupied status.
