Appendix B:

A773 SULFUR FILTER INSTALLATION & MAINTENANCE

4. Beginning on the “Flue Probe” side of the A773 sulfur filter, pull the yellow

thermocouple cord out of the channel of the flue probe tube. Pull out approx-
imately the length of the water trap that was removed.

5. Being careful not to cut the yellow cord, cut out a section of the flue probe

tubing the length of the water trap on the “Flue Probe” side of the A773 sul-
fur filter. (See picture below)

6. Install the water trap in the flue probe hose where the piece was cut out. Make

sure the water trap is positioned correctly. The water trap lid should face the
“Hose End” side of the hose.

A773 SULFUR FILTER MAINTENANCE:

The A773 should be replaced when most of the pellets become discolored, usual-
ly white or black.

If the A773 begins to trap condensate and fill with water but the pellets are not
discolored to the point replacement is required, it should be removed and allowed
to dry. Once it is dry it can be reused.
