Reflect-O-Ray® ALPHA® PACKAGE SYSTEMS PART 1 - GENERAL It is the intent of this specification to identify design requirements and minimum standards for the quality, construction, delivery, installation, and operation of the low intensity, vacuum vented, gas fired infrared heating equipment. Minor variations, in accordance with standard practice, shall be indicated on the shop drawings and submitted for approval. 1.1 - CODES AND STANDARDS
1.2 - QUALITY ASSURANCE
1.3 - MANUFACTURER AND INSTALLER QUALIFICATIONS 1.3.1 The low intensity, gas fired infrared heating system shall be a product of a manufacturer who has had at least ten years experience in design and fabrication and who is regularly engaged in the manufacture of the type of gas fired low intensity infrared heating equipment specified herein. Only manufactures who can submit evidence of actual installations of comparable designed construction, and that the products have proven practical, durable, and require a minimum of maintenance, will be qualified under this specification.1.3.2 Installation of the gas fired low intensity infrared heating equipment shall be by supervised by an authorized representative of the heater manufacturer and shall be in accordance with approved installation drawings. Mechanics shall be skilled and experienced in the erection of the low intensity infrared heating equipment of the type specified herein. 1.4 - DELIVERY AND STORAGE 1.4.1 Materials shall be shipped in the manufacturers standard protective packaging to the designated site. 1.4.2 The installing contractor is responsible for receiving, unloading and storage of materials. Storage shall be in dry locations free from dust and water and available for inspection and handling. Handle equipment carefully to prevent damage. Remove damaged items that cannot be restored to like new condition and replace with new items. PART 2 - PRODUCT 2.1 - BURNERS 2.1.1 Burners shall be capable of firing at 75,000 BTU/hr, 105,000 BTU/hr, or 130,000 BTU/hr inputs, with natural gas and at 75,000 BTU/hr, 105,000 BTU/hr or 120,000 BTU/hr inputs, with LP gas. 2.1.2 Burner power requirements 24 Volt, 60 Hz AC 40VA. 2.1.3 Burners shall include the following features: a) Burners shall operate under a negative (vacuum) pressure. b) Fitted with a 4" diameter combustion air inlet with a fixed combustion air-metering orifice. c) Burners shall be fitted a differential air pressure switch so as to prove adequate combustion air is present before burner fires. d) Burners shall be fitted with solid state, (3) try, (1) hour reset electronic controls with spark ignition & 100% lockout in event of low fire or main flame failure. e) Burner(s) shall have a minimum 15-second pre-purge before ignition. f) Burner(s) shall casing to be constructed of 16 Ga. aluminized steel, powder coated. g) Burner(s) shall be fitted with inspection window for visual inspection of spark and flame. h) Burner(s) shall be fitted with 3 indicator lights - "Power On", "Air Flow On", & "Burner On". i) Burner controls, differential pressure switch, gas valve, electrical wiring, etc. shall be segregated from the combustion air supply.
