Cleaning Instructions, Flue Passages Of The JWF657 Heater

Refer to Figure 13 for components of the heater.

1.Remove the casing top and lift the insulation off com- pletely. It is necessary to disconnect the hot and cold water lines and move them out of the way. Do not remove the nipples from the tank.

2.Lift off the flue collector. The flue collector has a lip on the outer edge which will allow a hook to grab the edge to help lift it up.

3.Remove the flue baffles (4).

4.With a 76mm (3 in.) diameter wire brush, 1.2m (4 ft.) long, remove any soot build-up which may be on the top head or inside the flue collector.

5.Reassemble in reverse order. It may be necessary to replace the gaskets around the nipples to seal them at the flue collector. Replace the insulation and the casing top.

6.Reconnect the plumbing lines.

Shut Down For Extended Periods

When away for extended periods of time such as vacation, and no freezing temperatures are expected:

1.Shut off the oil supply at the tank.

2.Shut off the cold water supply to the heater.

3.Turn "OFF" the electrical supply to the water heater.

4.Open an upstairs hot water faucet (to relieve any pres- sure).

When freezing temperatures are expected:

1.Shut off the oil supply at the tank.

2.Shut off the cold water supply to the heater.

NOTE: It is recommended that all water lines in the home be drained. Contact a qualified plumber for directions applicable to the heater.

CAUTION

Hydrogen gas can be produced in a hot water system served by this heater that has not been used for a long period of time (generally two (2) weeks or more).

Hydrogen gas is extremely flammable and can ignite when exposed to a spark or flame. 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 con- nected to the hot water system. Use caution in opening faucets. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.

1.Follow instructions for “Filling the Water Heater” and “Startup” when heater is ready to be put back into ser- vice.

2.If the heater does not start, check to see if the relay on the burner has tripped. Reset if necessary. Check to see if the thermostat is set at “Normal” or “High”.

3.If the heater does not start:

a.Turn "OFF" the electrical supply to the water heater.

b.Shut off the oil supply at the tank.

c.Call a qualified Oil-Burner Technician.
