Refer to Figures 4, 5, and 7 on pages 13 and 14 for recommended suspensions. 4. GAS SUPL Y Provide adequate gas supply for rated input of each heater using American Standard Installation of gas piping and gas appliances in building ANSI/223. 1a/ NFPA54 Pamphlet, Table C-3 shows capacity of pipe of different diameters and lengths in cubic feet per hour for Natural Gas with pressure drop of 0.3 inches specify gravity of 0.60. For liquefied Petroleum Gas (LP) capacity refer to Table C-3 and C-15 of the same pamphlet. For recommended heater gas connection refer to Figure No. 5, Page 15. In Canada refer to Can 1-B149.1 and B149.2, and CSA sto. B63. If gas lines are to be pressure tested with compressed air, disconnect each heater to prevent control damage and cap outlets. After reconnecting all heaters, purge gas lines of air and check all connections for leaks using soap solution. WARNING : Do NOT USE MATCH OR OTHER FLAME FOR LE AK TESTING. 5. GAS PRESURE When a higher than the maximum recommended gas pressure is being maintained at the main gas line, *High Intensity Heaters are only sold as 4040, 8060, 9100S, and 9120 **Different model numbers are achieved by using supplemental orifices included with heaters to change heat output. Enerco Group, Inc. |Gas-Fired Infra-Red Space Heaters 4 Operating Instructions and Owner’s Manual a separate regulator must be installed ahead of the heater. Refer to Figure 2 for maximum allowable pressure for stated model and gas. See heater rating plate for minimum gas supply pressure “For the Purpose of Input Adjustment” On a multiple heater installation it may be possible to use one large capacity regulator or an individual regulator for each heater. Nevertheless, it is recommended practice to make the entire pipe system a loop. Contact your local representative or the factory for proper gas pressure reducing design stage. WARNING : DO NOT EXCEE D . P.S.I. INLE T PRESSURE TO HEATERS SHOWN IN FIGURES 1 AND 2 6. ELECTRICAL All external wiring must be in accordance with the existing electrical code. Use wiring diagram furnished with heater. Be sure electric supply characteristics match those called for on the name plate. The unit must be electrically grounded in accordance with the National Electrical Code, ANSI/NFPA70, latest revision. In Canada refer to Canadian electrical code CSA C22.1 7. THER MOSTAT & LOCATI ON Make sure that the electrical characteristics of the thermostat match those of the heater controls. For best results thermostat should be positioned 5 ft. above floor where air can circulate freely around it. DO NOT MOUNT directly to cold-side wall, in direct drafts or directly beneath the infra-red heater. 8. VENTILATI ON a. The minimum intake and exhaust air openings shall provide for not less than 400 CFM for every 100,000 BTU input except that the infiltration area may be included in the intake area. The exhaust fan must be interlocked with the heater thermostat. If a power exhaust fan is used, it should be controlled by the thermostat or humidistat b. Where natural (gravity) ventilation is provided for exhaust, the openings must be distributed above the heaters (preferably at the peak of the roof) and the areas of openings shall not be less than 300 square inches for every 100,000 BTU input. 9. OPERATI ONS Upon completion of electrical wiring, gas piping and purging of gas lines to heaters, refer to the lighting instruction plate attached to heater for proper lighting procedure. 10. CLEANING IN FORMATI ON Blow out Venturi and burner face with compressed air (25# max. pressure); also clean orifices (see Figure 2 for correct size drill). For detailed maintenance and cleaning instructions contact your local representative or factory. WARNING : GASKET BINDER MATERIAL USED IN THIS HEATER ASSEMBLY WILL TEMPORARILY EMIT AN ODOR AND/OR VAPOR. USE VENTILATION (a OR b) AND THIS CONDITION WILL CLEAR UP IN APPROXIMATEL Y 20 MINUTES AND WILL NOT REO CCUR. WARNING : DO NOT ATTEMPT TO IGNITE THE PILO T BY HAND ON HEATERS EQUIPPED WITH AUTOMATIC spark igniti on. WARNING : THE STATE OF CALIFORNIA REQUIRES THE FOLO WING WARNING: COMBUSTION BY-PRODUCTS PRODUCED WHEN USING THIS PRODUCT CONTAIN CARBON MONOXIDE, A CHEMICAL KNOWN TO THE STATE OF CALIFORNIA TO CAUSE CANCER AND BIRTH DEFECTS (OR OTHER REPRODUCTIVE HARM).
