(Fig. 6) 2. Lay copper capillary sensing tube across top of the draft diverter. Allow excess tube to hang down right side of heater. Do not cut or crimp capillary tube. 3. Route the two wires from the spillage switch down the left side of heater to the ECO keeping the cables out of contact with hot surfaces. (Fig. 6) Connecting linear safety spillage switch to pilot safety circuit The ECO/temperature limiter is mounted on the lower left outlet water pipe. (Fig. 7) 1. Remove one wire lead connected to ECO terminal (it does not matter which one is disconnected). 2. Attach ." quick connect terminal end of linear spill switch cable to now exposed terminal of the ECO. 3. Connect the male spade connector to the removed lead wire from step 1. See the wiring diagram in Fig. 13 to confirm proper set up.

Check your model number on the right side of the water heater cover to confirm which procedure to follow. 2.7.1 Models 1600P/425PN 1. Shut off cold water supply isolation valve. If none installed, install before proceeding. Open hot water tap to relieve water pressure if water is already connected. 2. Remove and save clip on lower right side of heat exchanger. 3. Using a flat head screw driver remove and save pin from front, right side of water valve. (Fig. 8) 4. Remove copper pipe and set aside. 5. Find and connect the black flow switch to the bushing and pipes shown in Fig. 9A. Secure together with supplied clips. 6. Position flow switch and connecting pipe and bushing in place of the copper pipe that was removed. 7. Reinstall pin in water valve and clip on heat exchanger connection. 8. Connnect the three prong Molex connector cable to the flow switch. 9. Connect control cable from vent motor to Molex connector cable with wire nuts as seen in Fig. 10. 2.7.2 Models 1600H/425HN 1. Shut off cold water supply isolation valve. If none installed, install before proceeding. Open hot water tap to relieve water pressure if water is already connected. 2. Remove and save clip on lower right side of hydrogenerator. 3. Remove and save pin from front, right side of water valve using a flat head screwdriver. (Fig. 8) 4. Remove copper pipe and set aside. 5. Find and connect the black flow switch to the pipes shown in Fig. 9B. Note: There are two pipes included for connection from flow switch to hydro-generator. One is slightly longer than the other. If your water heater’s serial number is greater than FD792, you must use the longer pipe for this connection. 6. Position flow switch and connecting pipes in place of the copper pipe that was removed. Secure together with supplied clips. 7. Reinstall pin in water valve and clip on heat exchanger. 8. Connnect the three prong Molex connector cable to the flow switch. 9. Connect control cable to Molex connector cable with wire nuts as seen in Fig. 10.

The AQ4 power vent kit is equipped with a time delay relay. It is supplied with the time delay set at the (0.1) second position 2. If installing the AQ4 with standing pilot models 1600P or 425PN, no adjustment is required. 3. If installing the AQ4 with hydro ignition models 1600H or 425HN, move the adjuster on the time delay to the (2) second position. (Fig. 11B) 4. To access the time delay relay, unplug powervent and remove the electrical box cover on power vent motor.

Slowly turn on cold water supply and check for any leaks at newly installed flow switch and piping. 2. Plug power vent motor into 120VAC outlet. 3. With the gas supply to the water heater turned off (see water heater manual) turn on a hot water tap. The power vent motor should come on. Verify the back draft flapper is open and air is being blown out of the power vent hood. If not, see the troubleshooting tips in Chapter 5. 4. Turn off hot water tap. 5. Open gas supply to the water heater and follow the lighting instructions in water heater installation manual. 3.1.3 Draft test...
