if not eliminate water odour problems. The water supply sys- tem may require special filtration equipment from a water conditioning company to successfully eliminate all water odour problems.

Artificially softened water is exceedingly corrosive because the process substitutes sodium ions for magnesium and cal- cium ions. The use of a water softener may decrease the life of the water heater tank. The anode should be inspected periodically. If the anode is more than 50% depleted, the anode should be replaced.

VI) MAINTENANCE

Draining and Flushing

It is recommended that the tank be drained and flushed every 6 months to remove sediment which may buildup dur- ing operation. The water heater should be drained if being shut down for extended periods of time. To drain the tank, perform the following steps:

1.Turn off the gas to the water heater with the manual gas shut-off valve.

2.Close the cold water inlet valve.

3.Open a nearby hot water faucet.

4.Connect a hose to the drain valve and terminate it to an adequate drain.

Note: The drain hose should be rated for at least 94°C (200°F). If the drain hose does not have this rating, open the cold water inlet valve and nearby hot faucet until the water is no longer hot.

5.Open the water heater drain valve and allow all the water to drain from the tank. Flush the tank with water as needed to remove sediment.

6.Close the drain valve, refill the tank, and restart the heater as directed under “Operating Instructions”. If the water heater is going to be shut down for an extended period, the drain valve should be left open.

Important: Condensation may occur when refilling tank and should not be confused with a tank leak.

The installation and maintenance of the water heater must comply with all of the instructions described in sections I to IX of this manual. Water heater failure that is a result of the heating system is not covered by warranty.

The following maintenance procedures are for the Flame GuardTM safety system components and should be per- formed by a qualified service technician.

Replacement parts (see Figures 20 & 21) may be ordered through your local distributor. When ordering replacement parts, always have the following information ready:

1.Model, serial and product number.

2.Type of gas.

3.Item number.

4.Parts description.

Periodic Inspection

Periodically a visual inspection should be made of the vent- ing and air supply system, piping systems, main burner, pilot burner and flame arrester.

Check the water heater for the following:

1.Obstructions, damage or deterioration in the venting system. Make sure the ventilation and combustion air supplies are not obstructed.

2.Build-up of soot and carbon on the main burner and pilot burner. Check for a soft blue flame.

3.Leaking or damaged water and gas piping.

4.Presence of flammable or corrosive materials in the installation area.

5.Presence of combustible materials near the water heater.

6.Presence of debris on the outside of the flame arrester. See note below.
