Resumen del manual
8 INSTALLATION INSTALLATION: The Del Rey Heater provides radiant warmth *indoors (commercial applications only) or outdoors with a powerful 58,000 Btu/hr natural gas. All units are equipped with hot surface ignition and 100% shutoff valve for safety. Del Rey Heaters to be installed in Aircraft Hangers must be installed in accordance with American National Standards for Aircraft Hangers, ANSI/NFPA No. 409. Heaters to be installed in public garages must be installed in accordance with NFPA No. 88A standards for parking structures. Heaters must be installed so that minimum clearances marked on the heater will be maintained from vehicles parked below the heater. The installation must conform with ANSI standard No. Z223.1 National Fuel Gas Code and any applicable local codes. In Canada, the installation must conform with local building codes or, in the absence of local codes, with National Standards of Canada CAN/CGA-B 149.1 & 2-M86. Each heater must be electrically grounded in accordance with the National Electrical Code, ANSI/NFPA 70 when an external electrical source is utilized. In Canada, the CSA Canadian Electrical Code, C22.1, Part 1 applies. The gas inlet supply and normal operating manifold pressure for each heater are as follows. For gas supply line pressures in excess of 1/2 psig, contact your dealer or the factory. GAS INLET PRESSURE maximum: pressure Natural Gas: 1/2 psig minimum: pressure Natural Gas: 6 W.C. manifold: pressure Natural Gas: 5 W.C. The heater has an internal 5”W.C.regulator. Note: This unit is for use with natural gas only. WARNING: 1. This product must be installed by a licensed plumber or gas fitter when installed within the Commonwealth of Massachusetts. 2. When installing Mounting Body Assembly, make sure left hand and right hand Body Assembly are level. If not, escaping heat could easily cause damage to the components inside the compartment. 9 INSTALLATION Do not locate either the gas or electrical supply line directly over the flue outlet of the heater. Electrical supply line shortage and / or control overheating may occur. The heater must be installed in a location such that it is accessible for servicing and have no restriction of air flow to the air inlet of the heaters casing. MOUNTING Each heater must be installed such that the minimum clearance to combustibles are maintained. Combustible materials are defined as wood, paper, foliage, plastic, plexiglass or other materials capable of being ignited and burned. Such materials shall be considered combustible even though flame- proofed, fire retardant treated or plastered. Additional clearances may be required for glass, painted surfaces and other materials which may be damaged by radiant or convection heat. ELECTRICAL A 24 VAC, 40 VA transformer has been included with the product. The on-off control of the heater should be controlled from 120 VAC side of the transformer. A UL approved outdoor wall switch must be used for this purpose. The transformer must be mounted a minimum of 12” from the heater in a weather protected cover. Do not put the transformer in the heater (this will damage the unit.) A step down transformer approved as having at least a 40 VA rating must be utilized for each connected heater. Control wires used to electrically connect one or more heaters together must have both adequate capacity and insulation temperature ratings for the total connected load. Use at least 18 ga. wire up to 50 ft. from heater to transformer or wall switch. Use 16 ga. over 50 ft. distance. If the original wires supplied should need replacement, they must be replaced with wiring material having a temperature rating of at least 105 degrees Centigrade. GAS PIPING A minimum pipe size of 1/2” is required for inlet piping. A 1/2” lever handled shut-off gas cock should be installed within 6 feet of the appliance for servicing the unit. Check with local and state plumbing and heating codes regarding sizing of the gas lines. Installation of a drip leg in the gas supply line going to each heater is required to minimize the possibility of any loose scale or dirt within the gas supply line from entering the heater’s control system. 1/2" Conduit 10 LEAK TESTING IMPORTANT: VENTILATION A minimum building ventilation rate of 4 CFM per 1,000 BTU’s of installed heater input must be provided. This rate of ventilation may be obtained through either gravity or mechanical ventilation of the building. In conjunction with building ventilation system, adequate fresh air into the building must be provided through fresh air inlets and/or building inlets. It is recommended local code be checked to assure the ventilation system and heat installation are in compliance with local and/or state codes. When checking for gas leaks, do not use an open flame. Use a soap and water solution. Installation of 1/8” NPT plugged tapping, accessible for test gage connections, is required upstream of the gas supply connection to the heater. NOTE: Gas connections on the heater ...
