(see Figure 32).
NOTE:
Depending on the size of your
water heater, the filter may have some excess material.
This may be trimmed away.
4. It is recommended that the filter be inspected
periodically to maintain unrestricted airflow to the water
heater.
Periodic Cleaning of the Filter
1. If periodic inspection of the filter shows a build-up on
the filter, it should be removed and cleaned.
2. To remove the filter, locate a set of connection posts
(see Figure 32) and squeeze them together while
pulling outward on the thumb tab.
3. The filter can then be vacuumed to remove the build-up.
4. Before re-attaching the filter, a visual inspection of the
flame-trap is recommended. Refer to the “External
Inspection & Cleaning of the Flame-trap” section.
5. Follow Filter Installation instructions 2-3 to re-attach the
filter.

External Inspection & Cleaning of the
Flame-trap
Although not likely to occur, if debris collects on the flame-
trap, use a vacuum, compressed air, or a soft bristle brush
to remove it.
NOTE:
If unable to inspect or clean the flame trap from
underneath, follow the “Cleaning the Combustion Chamber
and Flame-trap” section instructions.
Cleaning the Combustion Chamber and
Flame-trap
1. Follow procedure outlined in “Removing the Manifold
Assembly”.
2. Use a vacuum cleaner/shop vac to remove all loose
debris in the combustion chamber (Figure 33). Use
compressed air to clear any dust or debris that may
have accumulated in the flame-trap.
3. Reassemble following the procedure under “Replacing
the Manifold Assembly”.
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 reattachement.
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
fi
lter be installed
properly.
If you encounter dif
fi
culty installing the
fi
lter or have a
question, please call the Service & Warranty Department at
1-877-817-6750.
Filter Installation
1. Before attaching the filter, remove any dust or debris
that may have accumulated in the installation area.
It is also recommended that a visual inspection of
the flame-trap be performed. Refer to the “External
Inspection & Cleaning of the Flame-trap” section.
2. Connect the end points of the filter sections together
(see Figure 32) to form one long section. Wrap this
section around the base of the water heater and join
at the closest connection point to fit your water heater.
NOTE:
If your water heater has a small diameter tank it
may be necessary to use both inner connection points).
3. Once connected, check to ensure a close fit with no
gaps between the water heater, the filter, and the floor
