NOTE: To prevent any bending of the pilot bracket, use pliers to hold the pilot assembly bracket while loosening the pilot nut.
4.Pull the pilot tube from the pilot assembly (Figure 31). IMPORTANT: Be careful not to bend or alter the position of the pilot assembly components.

5.Use a screwdriver to remove the screws securing the Pilot/Igniter - Flame Sensor Assembly. Keep the screws for reattachment.
6.Using the old pilot/pilot tube assembly as a guide, bend the new pilot tube to match the old one. Make only the bends closest to the pilot before going to the next step.
7.Push the new pilot tube and igniter wire through the hole in the manifold door (See Figure 30). Reconnect the pilot tube and tighten the nut securing it to the pilot assembly. IMPORTANT: Keep the pilot orifice in the pilot when making the connection. DO NOT operate the water heater without the pilot orifice installed. Reattach the pilot assembly to the manifold.
8.Be sure the igniter wire is positioned through the bottom opening of the manifold component block. See “Replacing Manifold Assembly” section.
Filter Installation and Cleaning
IMPORTANT: It is essential that the filter be installed properly. If you encounter difficulty installing the filter or have a question, please call the Service & Warranty Department at
Failure to install (and clean) the air filter assembly properly can allow dust and lint to restrict the air supply to the water heater. If that occurs, the pilot light could go out or the thermal switch could shut the water heater off. A service call could be needed to clean the flame trap. These condi- tions are not defects and are not covered by the warranty.

Air Filter Assembly Installation:

Install the air filter assembly as described below and clean as needed. Replace the air filter assembly with a new one if it is damaged.
1.Before installing the air filter assembly, remove any dust, lint or debris (including any packaging materials or tape) from under the water heater. For existing installations, a visual inspection of the
2.Wrap the filter around the base of the water heater. Cut to fit around a sensor if present. Trim excess filter material with scissors but allow filter material to overlap a few inches (Figure 32B).
3.The filter should fit snugly against the base of the water heater with no gaps. The filter must fit flush against the bottom of the drain pan and/or floor. Hold the filter in place, then stretch the filter clip over the overlapped joint and hook in place (Figure 32B).
4.Check the filter at least every three months and clean as necessary. After installation, the filter may be cleaned by using a vacuum cleaner with a brush attachment to remove lint and dust. NOTE: Because the amount of dust and lint in the air can vary, your filter may need to be inspected/ cleaned more often. In some instances, the filter may need to be removed and washed using mild hand soap and water to remove any oily residue. After washing, allow to dry and properly reinstall.
Never operate the water heater without a clean air filter.
