Water Quality And Maintenance
ATTENTION
If corrosion inhibitor is correctly maintained, corrosion failure cannot occur in the
water jacket . Corrosion in the water jacket is not a workmanship defect and is not
covered by the warranty .
Test Supply Water
Test a sample of the supply water (makeup water) that will be used to fill the
outdoor furnace (softened water is recommended). Test strips for testing
pH are included in the water test kit which is provided with the outdoor
furnace.
1. Collect a small sample of the water to be used to fill the outdoor
furnace in a clean container.
2. Dip the pH test strip from the provided test kit in the water sample.
Shake excess water off the test strip. Compare the color of the test
strip to the chart provided to determine pH level.
3. If the pH level is between 6.5 and 8.0 and there are no other known
water quality problems, then the outdoor furnace may be filled with this
water.
4. Water that has a pH level of less than 6.5 or greater than 8.0, or that
has other known water quality problems, should not be used to fill the
furnace. Instead, water should be supplied from a different source.
Adding Initial Water Treatment
CAUTION
Avoid damaging your furnace and voiding your warranty . Add water treatment
BEFORE adding water to the system . Water treatment in your outdoor furnace is
just as important as the oil in a car's engine .
MolyArmor 350 Corrosion Inhibitor (p/n 2900631) gives optimum protection
for the furnace water jacket and system parts when it is used to initially
treat the water and is maintained at a minimum of 350 ppm of moly and
pH level between 8.0 and 9.5. The recommended initial treatment rate for
the outdoor furnace is specified by units. One unit of MolyArmor 350 is a
1-gallon (3.78-liter) container.
