11.5 Combustion Chamber
If the Oasis SCH33 is operating properly, it should not produce
soot/ash deposits in the burner chamber. A build-up of soot in
the combustion chamber will create poor heater performance.
During regular service, using a bright flashlight, inspect inside the
combustion tube by looking through the combustion air holes in
the burner box. If there are viable soot deposits in the
combustion tube, they can be removed with a vacuum. If the
deposits are significant, the tube should be removed and
cleaned. When the combustion tube is removed, the combustion
chamber can also be cleaned. The exhaust pipe should checked
at this time and cleaned if necessary.
11.6 Checking Hoses and Tubes
Annually, check water hoses and tubes for leaks or weak points.
Check air and fuel lines, pay close attention to the condition of
the hoses especially around clamps. Hoses, air lines and fuel lines
will deteriorate over time and may crack. Replace any sections of
worn hose together with the clamp.
11.7 Electrical System
The electronic control panel should not normally require
servicing, except for the following:
• Make sure that all your connections are secure.
• Periodically, do a voltage test to ensure that you are
getting 12 volts from the battery.
• Check for corrosion of wires and connectors especially if
condensation is present
