Water Testing & Treatment
10.1 Overview
Properly testing and treating the water in the heater
water jacket is important to control waterside
corrosion. Untreated or improperly treated water can
reduce the life of the heater. The water in the heater
should be tested and if necessary treated to maintain
proper Nitrite and pH levels. A Startup Water
Treatment Kit is included with each heater. Further
treatment supplies are available for purchase.
10.2 Drawing Water for Testing
10.2.1 !!CAUTION!!:
Water in water jacket could be very hot. Draw water
with Caution!!
10.2.2 IMPORTANT!!
All water samples drawn for testing should be allowed
to cool to room temp. before testing with test strips.
10.2.3 Collecting Water
Water can be drawn from the water jacket at the
water level sight gauge. Open the valve and unclip the
clear plastic tube from the holder and bend the clear
tube downwards. Let water run from the tube for 10
seconds. Don't collect the first water draining from
the tube; after 10 seconds direct the water into a clean
container. Collect about 10 ounces of water.
10.3 Purchasing Additional Water
Testing and Treatment Kits
Water testing and treatment supplies are available for
purchase from your local dealer.
10.4 Nitrite Treatment
10.4.1 Initial Nitrite Treatment
Follow the instructions in with the Initial Treatment
Kit included with the heater to initially treat the water.

10.4.2 Adjusting the Nitrite Level Up
If the nitrite level is lower than 600 ppm, dissolve
another half puck of nitrite treatment in a 1 gallon
container or pail and pour into the overflow/vent pipe.
Circulate the water for at least 24 hours before testing
for the new nitrite level.
10.4.3 Adjusting the Nitrite level Down
If the nitrite level is too high drain 20 gallons of water
from the water jacket and refill with fresh untreated
water. Circulate the water for at least 24 hours before
testing for the new nitrite level.
10.5 Water pH Levels
10.5.1 Determining the pH level of the
water
NOTE: Before filling the water jacket check the pH
of the water to be used to fill the water jacket to insure
it is within the allowable range. Use only water that
has a pH level within the allowable range.
Follow the instructions included with the Initial
Treatment Kit included with the heater to determine
the pH of the water.
10.5.2 Adjusting the pH level Up or Down
If the pH level is not within the allowable range after filling
the water jacket, treatments kits for adjusting the pH level
up or Down are available for purchase.
10.6 Determining the Propylene
Glycol Level (if used)
Kits to determine the glycol level and freeze protection
level are available for purchase.
