6.1 Prior to Operation Prior to operation of the pump in the heating system, operation and proper rotation of the impeller must be verified. IMPORTANT: Improper rotation of the impeller will not produce the vacuum required for proper system operation. The EP-201 motor must be wired for clockwise or counterclockwise rotation as shown on Page 12, Figure 11. The EP-201 motor is wired for 1 O, 120 V, 60 Hz operation. The EP-201 motor can be rewired for 230 V operation by changing the motor connections as indicated by the diagram on the motor connection box cover. Wire the pressure switch per the CORAYVAC® (P/N 127102NA), VANTAGE® EV (P/N 151100NA) or appropiate controller installation manual. . *. . /0 . &&'() *+ ,- The EP-203 motor can be wired for 3 O, 208 V - 230 V, 60 Hz or 3 O, 460 V, 60 Hz operation. The EP-203 motor rotation direction can be changed by interchanging any two leads. Wire the pressure switch per the CORAYVAC® (P/N 127102NA), VANTAGE® EV (P/N 151100NA) or appropiate controller installation manual.

'" . . . 7.1 General Venting Requirements Install the venting in accordance with the requirements within this manual and the National Fuel Gas Code, ANSI Z223.1/NFPA-54 - latest revision and CSA 22.1 - latest revision. This section provides partial information about this specification with regard to size and configuration for venting requirements (see following figures). However, to provide assurance of proper and safe operation, it is the responsibility of the installer to make sure the installation is in strict accordance with all local and national codes. 7.2 Venting the Pump • The exhaust connection from the pump is 4.5" (11 cm) diameter. • Connect one of the flexible isolation boots provided to the 4" (10 cm) flue pipe, using the silicone rubber ring provided. • Connections to flue pipe larger than 4" (10 cm) require use of an appropriate "taper pattern reducer" (not supplied). • Venting from the pump may discharge either horizontally or vertically. Horizontal discharge is preferred. See Page 14, Figure 13. Vertical discharge must be arranged as shown on Page 15, Figure 14. Corrosion resistant pipe is required. • Both horizontal and vertical venting must be supported by suitable hangers. • Vent lengths are allowed as follows: VENT LENGTH VENT SIZE Up To 10' (3 m) 4" (10 cm) vent - 1 elbow Up To 25' (8 m) 5" (12.5 cm) vent - 3 elbow Up To 50' (15 m) 6" (15 cm) vent - 3 elbow 7.3 Horizontal Venting The vent material must be either porcelain coated tubing 4" (10 cm) O.D. (P/N 9141030D), heat treated aluminized tubing 4" (10 cm) O.D. (P/N 91409408), heat treated aluminized tubing 6"(15 cm) O.D. (P/N E0009105) or single wall flue pipe minimum 26 Ga. Vent length be limited to less than 30' (9 m). If using vent lengths greater than 30' (9 m), condensation will form in the vent pipe. Insulation and additional sealing measures will be required. 7.3.1 Horizontal Venting Guidelines • Vent must exit building not less than 7' (2 m) above grade when located adjacent to public walkways. • Vent must terminate at least 3' (1 m) above any forced air inlet located within 10' (3 m). • Vent must terminate at least 4' (1.2 m) below 4' (1.2 m) horizontally from or 12" (30 cm) above any door, window or gravity air inlet into building. • Locate vent terminal at least 12" (30 cm) from any opening through which vent gases could enter a building. • Use only corrosion resistant materials for the discharge line from the pump to the point of discharge. • Vent terminal opening must extend beyond any combustible overhang. • Install vent terminal at a height sufficient to prevent blockage by snow. • Protect building materials from degradation by flue gases. • Any portion of flue pipe passing through a combustible wall must be dual insulated and an approved thimble must be used. 7.3.2 Side Wall Venting Vent recommendations in order of preferred use: 1. Porcelain coated tubing 4" (10 cm) O.D. (P/N 9141030D) 2. Heat treated aluminized tubing 4" (10 cm) O.D. (P/N 91409408) Heat treated aluminized tubing 6" (15 cm) O.D. (P/N E0009105) 3. Single wall flue pipe - minimum 26 ga.
