To reassemble the Exhaust Manifold:
Exhaust Manifold Reassembly Instructions
1. Refer to Figure 10 and replace the exhaust manifold seal (part no. 84020) with the new
seal provided in the 24-month maintenance kit. Install the adhesive-backed seal in the
recess of the exhaust manifold flange (adhesive side down).
2. Align the exhaust manifold with the lower heat exchanger flange and secure it in place
using the three (3) bolts removed in step 4 of disassembly instructions. Alternately tighten
the bolts to obtain a uniform seal.
3. Reconnect the flue starter section to the exhaust manifold.
4. Prior to reconnecting the Condensate Trap, perform the procedures described in
paragraph 6.2.3.
5. Upon completion of the procedures in paragraph 6.2.2, reconnect the Condensate Trap to
the 1-1/2" O.D. pipe on the exhaust manifold per Figure 12.
