cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap prevents moisture and contaminants from going into the heater controls. If the sediment trap is not installed or is installed wrong, the heater may not operate properly.

Test for gas leaks with a mild soap and water solution. Apply water/soap solution with brush only - do not over apply. NEVER test with an open flame.
