Resumen del manual


(Check local codes for additional information.) b) Minimum six (6”) inch O.D. vent is recommended. Common Venting a) Horizontal run to vent must never exceed 75% of the vertical height of the vent. Refer to ANSI Z223.1 - latest revision, NFA-54 for proper vent sizes and installation. b) Open area of common vent must equal the sum of the open area of individual vents connected to it. (See chart and diagrams - page 25.) c) Use double wall vent as required (check codes.) d) Heaters sharing a common vent must be controlled by the same thermostat. e) All joints must be sealed using suitable products (see recommendation for horizontal vent - page 24.) f) Connections to common stack must be positioned to avoid direct opposition between streams of combustion gases. Outside Air Supply a) See procedure and diagram on page ??. FIGURE 12: Unvented Operation 1) Ventilation equal to 4 CFM per 1,000 BTU/hr. firing rate must be provided in unvented heater installations. 2) For dimensions A “unvented” refer to (Figure 1 — Minimum Clearances to Combustibles.)

H side view Roof Secure all joints with 3 (minimum) #8 x 3/8" sheet metal screws and seal all joints. Vent Adapter Stk. #19021 plan view At least 1/4" per foot rise or pitch must be maintained on horizontal runs from heater to vent. Outside Combustion Air Supply The Ener-Radiant XL heater is approved for installation with an outside air supply system. Some compounds such as halogenated hydrocarbons or other corrosive chemicals in the air can be drawn into the equipment and cause an accelerated rate of corrosion of some of the heater components. The use of such chemical compounds near the enclosure should be avoided. IMPORTANT: If the building has a slight negative pressure or contaminants are present in the air, an outside combustion air supply to the heaters is strongly recommended. For an outside air supply, a four (4”) inch O.D. single wall pipe may be attached to the heater. The duct may be up to forty-five (45’) ft. maximum length or two (2’) ft. minimum length with no more than two (2) elbows. (See General Requirements in page 21 for additional information.) An outside air supply should not be used with the draft hood venting configuration. The air supply duct may have to be insulated to prevent condensation on the outer surface. The outside air terminal should be securely fastened to the outside wall by drilling four (4) 1/4” diameter holes in the outside flange; wood screws or bolts and expansion sleeves may be used to fasten terminal. FIGURE 16: Non-Pressurized Outside Air Supply Duct Outside Air Terminal: Use ACME #104 Enerco Stk. #19030. PVC Pipe, “Dryer Hose”, or equivalent may be used instead of standard vent pipe. Section 6 Gas Piping Read applicable warnings in (Section 1) before proceeding with Gas Pipe installation. Improper installation may result in property damage, severe injury, or death. Meter and service must be large enough to handle all the burners being installed plus any other connected load. The gas line which feed the system must be large enough to supply the required gas with a maximum pressure drop of 1/2” water column. When gas piping is not included in the layout drawing, the local gas supplier will usually help in planning the gas piping. A 1/2” tapping at each burner location must be located and oriented as shown in (Figure 17). To check system pressure, put a plugged 1/8” NPT tapping in the gas line at the connection to the burner farthest from the supply. Before connecting the burners to the supply system, verify that all high pressure testing of the gas piping has been completed. Do not high pressure test the gas piping with the burners connected. Follow these instructions to ensure a professional gas supply installation: • Support all gas piping with suitable pipe hanging materials. • Use wrought iron or wrought steel pipe and malleable iron fitting. All pipe fittings should be new and free from defects. Carefully ream the pipe and tubing ends to remove obstructions and burrs...
