forming droplets, these drip into the fire or run out on the floor.
This is common at the time of startup after installation, during
periods of time when incoming water is very cold, or the heater
may be undersized for the requirements.
Droplets from the bottom of the flue may be due to corrosive
combustion products or improper vent. Check with your dealer
for more information.
CATHODIC PROTECTION - ANODE (FIG. 1)
The anode rod within the tank is designed to be slowly consumed
cathodically, minimizing corrosion in the glass lined tank. A
hydrogen sulfide (rotten egg) odor may result if water contains
high sulfate and/or minerals. Chlorinating the water supply should
minimize the problem. (See EXTENDED NON-USE PERIODS).
NOTE: Anode must remain installed (except for inspection) to
avoid shortening tank life. See LIMITED WARRANTY. Replace
as necessary.
WARNING: DO NOT BY-PASS ANY CONTROLS TO MAKE HEATER OPERATE.
OPERATE ONLY AS WIRED FROM FACTORY.
