MAINTENANCE MAINTENANCE Routine Maintenance Routine maintenance will help your water heater fast longer and work better. If you can't perform these routine maintenance tasks yourself, contact a qualified person. Draining and Flushing the Water Heater Tap water contains minerals that can form sediment in the bottom of the tank. The amount of sediment formed depends on the hardness of your tap water, the temperature settings, and other variables.
MAINTENANCE Refill the tank by opening the 10 cold water supply valve, Make sure a hot water faucets open and the drain valve is closed. Allow 2 hot water faucet to run full for at least three minutes to make sure the tank has all the air removed and is completely full of water. Once you are ca rain the tank is completely full of water, close the hot water faucet. Relight the pilot using the 11 instructions on page 23 and adjust the gas control knob to the desired temperature.
MAINTENANCE MAINTENANCE Actuator gas supply line is crimped or plugged if the actuator gas supply tube is crimped, kinked, or plugged, replace the actuator assembly {actuator, bracket, and supply tube). When you are finished, check for gas leaks by brushing on an approved noncorrosive leak detection solution. If such a solution is not available, use a mixture of hand dish washing soap and water {ons part cheap to 15 parts warier} or children’s soap bubble solution. Bubbles forming indicate 2 leak.
MAINTENANCE £ WARNING] Hot water will be released. Before operating the T&P relief valve manually, check that it will discharge in a safe place. f water does not flow freely from the end of the discharge pipe, turn the gas control fob o the GFF position and call a qualified person to determine the cause. At least every five years, have 3 qualified person inspect the T&P Relief Valve and discharge pipe.
MAINTENANCE MAINTENANCE Removing the Gas Control Valve/Thermostat: Remove the ignite with the ignite bracket by sliding & 1/4” flat-head screwdriver behind the top of the ignite bracket and gently remove allowing the ignite to hang freely off to tha side of the unit.
MAINTENANCE IMPORTANT: Use approved thread sealant tape or pipe joint compound on the gas inlet piping connections and the fitting on the back of the gas control valve/thermostat.
