Draft Hood/Damper Installation
Do not operate water heater with damper in closed position, it must be in the open position during water heater operation.
Do not negate the action of any existing safety or operational controls.
Install the supplied draft hood and damper on the flue outlet collar. Use only the supplied draft hood and damper, DO NOT use any substitute or alter the components in any way.
Place the damper on the water heater (see figure 3A). Align the four pilot holes on top of the water heater with the 4 corresponding holes on the damper bracket and secure with the supplied screws. Next, align the draft hood legs with the 4 corresponding pilot holes on top of the water heater and attach securely with the supplied screws. Locate the wiring from the ECO, and attach it to the wiring harness on the damper (see Figure 3A). Once damper is installed, ensure that the damper posi- tion indicator is visible (See figure 3A).
