WOODMASTER OUTDOOR FURNACES • OWNER'S MANUAL
NOTE: It is important to bring the water in the system up to operating temperature
(i.e., 170˚F or 76˚C) immediately after filling the system. This also applies any time
water is added to the system .
NOTE: The sight gauge valve should always be closed except when checking water
level . Water will automatically drain from the sight gauge tube . Remember that this
type of valve requires only 1/4 turn to open or close .
2. Check the system for leaks again. Inspect all fittings and hose ends for
any signs of leakage; repair as necessary. If a screw-type clamp has
been used, it may be possible to stop a very slow leak at a hose clamp
by tightening the clamp after the system has warmed up and the poly
becomes more pliable. It might also be necessary to install a second
hose clamp with the screw positioned on the opposite side.
Test the Treated System Water
After circulating the water in the system for 24 hours, test the treated
system water for the recommended moly (at least 350 ppm) and pH level
(between 8.0 and 9.5).
CAUTION
The water at the drain may be hot . Use caution when obtaining a sample .
1. Obtain a system water sample from the drain at the back of the
furnace. Before collecting the sample, open the valve and drain about
a quart of water; then carefully fill the sample container without
contaminating the sample. Be sure to properly close the valve when
finished.
2. Dip a pH test strip from the 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. The pH of the treated water should be
between 8.0 and 9.5.
3. Follow the instructions provided in the water test kit to test the moly
level of the treated system water.
Maintenance Levels
Test the pH and moly levels after the first three months and every six
months thereafter, and after adding water to furnace.
NOTE: It should not be necessary to add water to the outdoor furnace more
frequently than once every twelve months . If it is more frequent, either there is a
leak in the system or the outdoor furnace is boiling because of improper operation or
maintenance (see Troubleshooting Section in the Owner's Manual) . Be sure to locate
and repair the problem immediately . Frequently adding water can cause deterioration
in the water jacket . Each time water is added, refer to Water Quality and Maintenance
in the Owner's Manual for water testing procedures . If indicated by test results,
add MolyArmor 350 as required . Deterioration due to improper operation and/or
maintenance is not covered by warranty .
