4.2.3 PREPARING THE FLUE VENT PROBE HOLE
1. If the unit has been installed using the recommended AL29-4C vent, there will be a 3/8” hole, 18” to
24” above the exhaust manifold. The outer vent section, that covers vent section connections must be
loosened and slid down to uncover the hole (see Fig. 4.2).
2. If equipped with one, adjust the stop on the combustion analyzer probe so that it extends into the flue
gas flow without hitting the opposite wall of the flue. Do not insert the probe at this time.
