SECTION 15540

HIGH INTENSITY INFRARED GAS HEATER

***** Fostoria Industries, Inc. manufacturers two types of gas fired infrared heaters used for comfort heating. The heater covered by this guide specification, is a high intensity gas infrared heater. Multiple units can be used for total areas or single units can be used for spot heating. The other type manufactured by Fostoria Industries, Inc. are low intensity, positive pressure gas infrared tube heating systems consisting of a gas burner which heats a continuous metal tube and a reflector which directs infrared energy onto the floor or other objects.

This guide specification, SECTION 15540 - HIGH INTENSITY INFRARED GAS HEATER, can be used to specify Fostoria FS Series High Intensity Gas Infrared Heaters, an overhead gas-fired heater with cast aluminum burners, ceramic ray-heads, and aluminum reflector.

Infrared radiation is invisible electromagnetic radiation with wavelengths longer than those of visible light. Infrared rays pass through the air and do not create heat until they strike an opaque object. Infrared heaters direct energy onto people and objects. Re-radiation from floors and other objects in turn heats the surrounding air. Infrared energy travels at the speed of light in straight lines from the heat source. This energy diffuses as a function of the square of the distance it travels from the heat source. Intensity, therefore decreases in a proportional manner. For example, at 20 feet from the heat source energy intensity is 1/4 the intensity developed at 10 feet.

Heating levels will be determined by mounting height, spacing, reflector beam pattern, and gas input. For each Fostoria heater there are options for gas input, sizes, reflectors, controls, and method of installation. Refer to Fostoria product literature for availability of options, standard sizes, and guidelines for selection of heater model. Various options are listed in this specification section, but not all options apply to all heaters. The specifier will need to select the appropriate options, verify their availability, and delete non-applicable models and options. *****
