000775 12.12 1. Product Information 1.1 Function Description The RSV chimney fan is intended for use as part of a chimney, stack or venting system. The Use fan is designed to withstand the high temperatures associated with combustion, and can be used with natural gas, LP-gas and oil-fired heating appliance systems where flue gases do not exceed 575oF (300oC) for intermittent operation and 482oF(250oC) for continuous operation.
3000775 12.12 1.3 Shipping The fan is shipped in a corrugated cardboard box. A transport securing device may be attached to the bottom of the fan to hold the motor and impeller in place. Do not remove the device until the fan is at the installation point. Do not remove the transport securing device until the fan is being installed on the duct or the roof curb. The motor shaft could be damaged.
3000775 12.12 3. Mechanical Installation The code requirements for a mechanical draft system are different than those for a gravity venting system used with gas or oil-fired applications. Generally, the mechanical draft system must be installed a minimum of 3 feet away from any forced air inlet located within 10 feet and a minimum of 4 feet away from any door or window. For complete information, consult ENERVEX or your local building codes. 3.
3000775 12.12 3.4 Single Fan on Brick Chimney The installation procedure is the same for round and square flues. If a clay flue liner is installed and extends beyond the chimney, cut it back so it extends no more than 1/2 inch above the chimney crown. Fig. 5 Apply a bead of high-temperature silicone around the edges of the flue tile. Place the fan over the flue and make sure the fan is completely sealed to the clay tile.
3000775 12.12 3.6 Multiple Fan Installations It is possible to install multiple fans in parallel. For details, please contact ENERVEX. The fans must be placed so they can be opened for maintenance and chimney access. Fig. 8 shows optimal placement. Fig. 7 3.7 Installation for High Temperatures If the fan is used for applications where the flue gas temperatures exceed 482°F at the flue exit, dilution air is required. Dilution air allows cool air to dilute the warm flue gases.
3000775 12.12 4. Electrical Installation 4.1 Electrical Requirements Power requirements depend on the fan size and they can be found on page 4. Danger: Turn off electrical power before servicing. Contact with live electric components can cause shock or death. Notice: If any of the original wire supplied with the system must be replaced, use similar wire of the same temperature rating. Otherwise, insulation may melt or degrade, exposing bare wire. 4.
3000775 12.12 4.3 Wiring Diagram for RSV 400-450 The wiring diagrams below shows a three-phase fan connected to the power source (see Fig. 10). Use a 3-conductor wire of minimum 14 AWG with ground. Wiring must be run outside the chimney/stack in flexible or rigid metal conduit. Where variable speed is required, the fan is connected to a variable frequency drive (VFD). Wire according to Fig. 10 for systems using the ABB ACH550 series VFD. Fig.
3000775 12.12 RSV 400-450 can operate at either 3x208-230 VAC (default) or 3x440-480 VAC. The motor wiring terminals in Fig. 11 show default jumper positions for 3x208-240VAC operation. If the application requires 3x440-480VAC operation, the jumper positions must be changed according to Fig. 12. Fig. 11 Fig. 12 After wiring, make sure the motor is rotating in the proper direction. This is marked on the motor end cover.
3000775 12.12 6. Maintenance and Troubleshooting 6.1 Maintenance Intervals • • • • The RSV Chimney Fan is designed for continuous use. For gas applications, no regular maintenance is required. For oil applications, inspect the axial vane or impeller after (3) months and set up a periodic inspection based on these findings. Clean as required. The fan motors are equipped with permanently lubricated sealed ball bearings. They do not require lubrication. 6.
