Aqua-Hot Maintenance Procedure
Step 4: Remove the Diesel Burner (continued)
1. Carefully pull the diesel burner away from the Aqua-
Hot 4 - 5 inches before rotating the burner, then
remove completely as shown in Figure 138.
Step 5: Clean and Inspect the Combustion Chamber
and Heat Transfer Tabs
1. Remove the combustion chamber by loosening and
removing the four nuts, securing the combustion
chamber to the boiler tank and pulling it straight out,
approximately 16 inches.
2. Once the combustion chamber has been removed,
use a long handled wire brush, and brush the heat
transfer tabs to loosen soot deposits. Failure to do so
will reduce the Aqua-Hot’s heat transfer capabilities.
NOTE: To remove the diesel burner, it maybe necessary to
disconnect the ETS Module and High-Limit Thermostats
from the diesel burner’s thermostat plug.

NOTE:
If the heat transfer tabs are excessively sooty, it may
be necessary to vacuum the soot out of the heat transfer
tabs. If there is minimal soot, it may be left in the heat
transfer tabs, and will be evacuated out of the exhaust pipe,
upon start up of the diesel burner.
Use caution when handling the combustion chamber,
it may be extremely hot and serious burns could
result from touching a hot combustion chamber�
