CAUTION
Hydrogen gas can be produced in a hot water system served by these heaters that
have not been used for a long period of time (generally 2 weeks or more). Hydrogen
gas is extremely ammable. To reduce the risk of injury under these conditions, it is
recommended that the hot water faucet be opened for several minutes at the kitchen
sink before using any electrical appliance connected to the hot water system. If hydrogen
is present, there will be an unusual sound such as air escaping through the pipe as the
water begins to ow. There should be no smoking or open ame near the faucet at the
time it is open.
Small amounts of electric currents may move to your boat through your shore cord,
causing galvanic damage to your water heater. To help prevent possible damage, a
galvanic isolator is recommended. Galvanic corrosion IS NOT covered under warranty.
ANODES
In a small number of instances tap water may have sufcient concentrations of dissolved
salts to cause corrosion of the heater tank. Anode rods preserve the life of a water heater
by corroding themselves so the water heater doesn’t. These anode rods are easy to
install! Simply replace the drain plug with this product to protect the water heater tank.
Note:
DO NOT USE ZINC ANODES. THEY WILL NOT PREVENT
CORROSION TO YOUR HEATER TANK!!!!
