Resumen del manual


cut the copper capillary sensing tube. The other end of the tubing should now extend to burner area close to pilot, position it just below the stainless steel burners. This tube should not discharge into 2. The linear spill switch should mount in a location where the tube can extend across the top of the draft diverters while allowing the switch cables to reach the ECO. the flame nor should it extend above the upper edge of the burners. This tube vents gas to the (See Figure C, page 5) combustion chamber for ignition in case of a 3. Route the cables to the ECO switch inside the diaphragm failure in the gas pressure switch. water heater keeping the cables out of contact with hot surfaces. NOTE: The gas pressure switch has a built in pressure tap marked "gauge port". Use this tap instead of the heater's manifold tap when SAFETY CIRCUIT checking manifold pressure. (See Figure A) The linear spill switch, when wired in series with the Thermocouple or Pilot Flame Sensor and ECO(s) of the water heater, form the Safety Circuit. 4 1. The ECO is mounted on the lower left outlet water pipe. (See figure C) a. Remove one lead connecting to ECO terminal, it does not matter which one is disconnected. b. Attach 1/4" quick connect terminal end of linear spill switch cable to now exposed terminal of the ECO. c. Remove the eyelet ended terminal from the other spill switch cable. Affix the push on male spade connector, which is provided with the AQ1, to this spill switch cable. d. Connect this male spade connector to the removed lead wire from step 3.a. The linear spill switch should be attached to the upper right-hand side on the draft hood diverter (see figure D), on the Model 425HN and 125HX the linear spill switch should be attached to the upper left-hand side of the draft hood diverter. There are two holes provided for attachment on this diverter and only the front most hole should need to be used. With the provided #12 self tapping sheet metal screw securely mount the spill switch bracket to the diverter. For ease of access position it so the reset button faces outward and then bend the bracket so the switch can stand vertically. The copper capillary sensing tube should then be directed to the opposite end of the draft hood diverter, by laying it in front of the 5" diameter vent pipe opening, and down the other side of the draft hood diverter. FIGURE C DISCONNECT EITHER WIRE FROM ECO TERMINALS ON HOT WATER PIPE. PUSH ON ONE SPILL SWITCH LEAD CABLE TO ECO AND OTHER (RETROFIT FIRST) INTO EITHER WIRE THAT WAS REMOVED. ECO ECO HOT WATER PIPE FIGURE D CAPILLARY SENSING TUBE RESET BUTTON SPILL SWITCH CABLES NOTE: ON THE MODEL 425HN AND 125HX, REVERSE THE DIRECTION OF THE CAPILLARY SENSING TUBE SO THE RESET BUTTON ASSEMBLY IS ATTACHED TO THE UPPER LEFT-HAND SIDE OF THE DRAFT HOOD DIVERTER. 5 COMMON SETUP 4" single wall pipe* (galvanized or stainless steel) or 4" B-type vent*. * Single wall vent pipe requires a 6" clearance to combustibles. B-type vent (double wall) requires a 1" clearance to combustibles. Use of B-type vent is not permissible downstream outlet side of the fan motor. Any additional vent pipe used between the fan motor and the vent hood must be positive pressure rated with all seams sealed to prevent leakage. Single wall galvanized or stainless steel pipe is best. Vent Hood (see freeze prevention information on page 2) Power vent motor 5" to 4" vent reducer pipe FIGURE E 125B Model shown Mount gas pressure switch against wall See Figure D, page 5 for location of Linear Spillage Switch 6 NOTE: FOLLOW REQUIREMENTS IN FIGURES F & G ON THIS PAGE BEFORE INSTALLING VENT HOOD, THEN USE TEMPLATE ON PAGE 13 TO CUT HOLE. CAUTION Failure to follow these installation instructions may violate applicable national and/or local codes The vent system must terminate so that proper clearances are maintained as cited in the National Fuel Gas Code, ANSI Z223.1 "The exit terminals of mechanical vent system shall be located not less than 7 feet above grade when located adjacent to a public walkway. The venting system shall terminate at least 3 feet above any forced air inlet within 10 feet. The venting system shall terminate at least 4 feet below, 4 feet horizontally from or 1 foot above any door, window or gravity air inlet into any building." Also, "The vent terminal shall also not be installed closer than 3 feet from the inside corner of an L-shaped structure, or less than 1 foot above grade." FIGURE F POWER VENT FAN AND MOTOR Code Requirements Power vent installation must be in accordance with the following requirements of the National Fuel Gas Code: • All portions of the vent system under positive pressure during operation (on the downstream outlet side of the fan motor) shall use galvanized or stainless steel single wall vent pipe and be sealed to prevent leakage of flue gases. 2. Power venter must be mounted with motor shaft horizontal to prevent motor bearing wear. 3. Power venter housing is single walled. A 6" clearance from c...
