User manual FIELD CONTROLS 46114900

[. . . ] The vent hood should be chosen that matches the outlet size of the Power Venter. Note: Different sizes may be used as long as the reducers and specific size pipe are considered when determining equivalent length of vent pipe. SWH-1-3 - 3 inch SWH-1-4 - 4 inch SWH-1-5 - 5 inch SWH-1-6 - 6 inch SWH-1-8 - 8 inch Typical Side Wall Vent Hood Page 2 C. CONTROL KITS: The following are the most commonly used Control Kits. CK-20F: For operation with 30 millivolt or 750 millivolt gas-fired water heaters, gas-fired space heaters and gas-fired pool or spa heaters with an internally mounted thermostat. [. . . ] Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage. This equipment is designed to overcome minor negative pressure conditions. To ensure extreme negative pressure does not exist, follow the "General Installation Inspection" section of this manual. G. Heating appliances equipped with draft hoods, such as boilers or furnaces, LP and natural gas appliances SHOULD have a secondary spillage switch installed. On appliances without draft hoods, it is recommended that the secondary safety switch WMO-1 be installed into the system. Gas-fired 30 millivolt power systems MUST be equipped with a spillage switch. Air flow adjustment MUST be made to ensure appliance efficiency. This should be done at the appliance exhaust outlet with a velocity meter, draft gauge or by the "match test procedure". The match test is in accordance with National Fuel Gas Code A. N. S. I. Z223. 1, Section 8. 6. Page 5 I. On oil-fired and gas-fired heating appliances not equipped with a draft hood, a barometric draft control MUST be installed to regulate proper air flow and fluctuations in the system's air flow during operation. Fluctuations can come from wind loads on the outlet of the venter, house depressurization during windy days and the different house ventilation requirements between summer and winter operation. For gas appliances use a Field Controls Type MG-1 Barometric Draft Control. CONNECTING VENTER TO APPLIANCE: The venting system should be installed and supported in accordance with the National Fuel Gas Code A. N. S. I. Z223. 1, or in accordance with any local codes. A vent pipe connector shall be supported for the design and weight of the material employed, to maintain clearances, prevent physical damage and separation of joints. A vent pipe increaser or reducer may be required for connecting the venter to the vent system. Smaller vent pipe sizes than a chimney-vented system may be used for the vent system. Route the vent pipe from the appliance to the venter using a minimum number of elbows as possible. The horizontal section of the vent pipe should have a slight upward slope from the appliance to the venter. For clearances to combustible materials, multiple appliance venting and other installation requirements, refer to the National Fuel Gas Code A. N. S. I. Z223. 1, and/or any applicable local codes or appliance manufacturer's installation instructions. GENERAL WIRING INSTRUCTIONS: The PVE-100, 300, 600, and 1200 are designed to be used with either millivolt, 24 VAC, or 120 VAC appliances when used with the appropriate controls. For use on a millivolt controlled system a Field Controls HWK-6 or an appropriate Control Kit is required. For use on a 24 VAC or 120 VAC controlled system a Control Kit must be used. Refer to the installation manuals for the HWK-6 and individual Control Kits for wiring instructions. [. . . ] Determine that the pilot or burner is operating properly and that the main burner ignition operates satisfactorily, by interrupting and re-establishing the electrical power of the appliance in any convenient manner. Test the pilot or burner safety device to determine if it is operating properly by extinguishing the pilot or disconnecting the flame safety circuit and pressure switch sensing tube from pressure switch. Visually determine that the main burner is burning properly; i. e. , no floating, lifting or flashbacks. Perform a smoke test on oil-fired system; the burner should operate at a zero to a trace smoke. [. . . ]
