[. . . ] 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. 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. CK-21: CK-41: CK-43: For operation with gas-fired instantaneous water heaters with a pressure tap port in the burner manifold. For operation with gas-fired furnaces, boilers, unit heaters and water heaters operating with a 24 VAC gas valve. [. . . ] For venting systems equipped with a post purge device, the power venter operates for a period of time after the burner has shut off to purge remaining flue gases. Plan the vent system layout before installation to avoid the possibility of accidental contact with concealed wiring or plumbing inside walls. Single wall vent pipe may be used to join an appliance to the venting system, but if proper clearances cannot be maintained from combustible materials, Class B Vent Pipe should be used for gas appliances and Class L Type Vent Pipe for oil appliances. 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. 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. 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. The small steel tube mounted on the inlet to the PVE power venter must be connected to the air pressure switch on the Control Kit. This enables the primary safety feature of the PVE power venter system. [. . . ] This procedure should be recognized as a generalized procedure which cannot anticipate all situations. Accordingly, in some cases, deviation from this Page 8 procedure may be necessary to determine safe operation of the equipment. If it is determined that a condition exists which could result in unsafe operation, the appliance should be shut off and the owner advised of the unsafe condition. Corrections must be made before the appliance is put into continuous operation. [. . . ]
