reaction between this rod and the water. The most common
complaint associated with the anode rod is a “rotten egg smell”
produced from the presence of hydrogen sulfide gas dissolved
in the water. Do not remove this rod permanently as it will
void any warranties, stated or implied. A special anode can
be ordered if water odour or discolouration occurs. This rod
may reduce, if not eliminate, water odour problems. The water
supply system may require special filtration equipment from
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 calcium ions. The use of a water softener
may decrease the life of the water heater tank. The anode rod
should be inspected every year. If the rod is more than 50%
depleted, the anode rod should be replaced.
V) MAINTENANCE
Do not attempt to repair your water heater. Call a qualified
Oil-Burner Technician for service. Turn “OFF” the electric
power whenever the water supply is shut off. Before calling
for service, check that:
1. The heater is properly filled.
2. The electrical supply has not been interrupted.
Professional Maintenance
Except for external appearance and area tidiness, the
following steps should be performed only by a qualified Oil-
Burner Technician.
1. Lift out the flue baffle to clean the flue. (On rear and
combination flue heaters, the top cover, insulation and
flue top cover must be removed.)
2. Insert a flue brush down the flue passage way(s) to
remove soot and dirt. Soot or carbon that falls into the
combustion chamber will burn up within a very short time.
3. In normal use, there should be no large accumulation of
soot in the combustion chamber. If there is, remove the
burner and carefully brush or vacuum the combustion
chamber.
Note: The combustion chamber is not a replaceable
component.
Have your oil filter cleaned or replaced by a qualified
technician at an interval recommended by your oil supplier.
Flue Pipes
Once a year, inspect the flue pipe leading from the heater to
the chimney. If corrosion is evident, or discolouration at the
joints can be seen, replace the flue pipes. This should be
done by a qualified Oil-Burner Technician. Flue pipes must be
replaced by the same size flue pipe as the flue collar (breech
connection) at the heater.
Combustion Tests
Burner adjustments:
Final burner adjustments must be made using combustion
test equipment to assure proper operation.
1. Fill heater with water. Do not fire heater without water or
sections will overheat.
2. Refer to burner manual for start-up.
3. Allow heater to heat to design condition.
4. Using combustion test equipment, adjust burner for:
a. a trace of smoke between #0 smoke and #1 smoke.
b. over-fire draft in combustion chamber per Table 3.
Note: For JW6 F307V also see additional “Installation
Instructions for Through-the-wall Venting Components" that
is supplied with the JW6 F307V.

Routine Preventative Maintenance (By Owner/
Operator)
As a precaution against fire, and to maintain an adequate flow
of combustion air to the heater:
• Keep the appliance area clear and free from combustible
material, gasoline and other flammable vapours and
liquids.
• Keep the air ventilation openings unobstructed. If dust and
lint is seen accumulating around the openings, remove it.
• Do not pile cartons, papers, or combustible materials on
top, or near the heater (see Figure 1).
Draining And Flushing
• Burn hazard.
• Hot water discharge.
• Keep hands clear of drain
valve discharge.

DANGER
It is recommended that the tank be drained and flushed
every 6 months to remove sediment that may build up during
operation. The water heater should be drained if being shut
down during freezing temperatures. To drain the tank, perform
the following steps:
1. Turn "OFF" the electrical supply to the water heater.
2. Turn "OFF" the oil supply to the water heater.
3. Close the cold water inlet valve.
4. Open a nearby hot water faucet.
5. Connect a hose to the drain valve and terminate it to an
adequate drain.
