Water Temperature Regulation
Water temperature over 52°C
(125°F) can cause severe
burns instantly resulting in
severe injury or death.
Children, the elderly, and the
physically or mentally
disabled are at highest risk
for scald injury.
Feel water before bathing or
showering.
Temperature limiting valves
are available.
Read instruction manual for
safe temperature setting.

DANGER
Once installed, the operation will be completely automatic.
The thermostat (aquastat) on the water heater is adjustable
and will maintain water at the desired temperature.
Set the tank thermostat as low as possible to provide an
adequate supply of hot water. This will conserve oil and extend
the life of the tank.

To adjust the thermostat
• Disconnect power to the heater
• If the temperature dial is visible, turn the dial by inserting a
small slotted screwdriver in the screw-head just below the
window in the cover. Turn the scale to the desired setting
(see Figure 12).
• If the dial is not visible, remove the cover and adjust the
"LO" setting knob to the desired setting. Replace cover
• Reconnect power to the heater.

Water Heater Operation
WARNING
Keep the area around the heater clear and
unobstructed.
Stacking
Stacking occurs when a series of short draws of hot water
(11 litres (3 US gallons) or less) are taken from the water
heater tank. This causes increased cycling of the burner and
can result in increased water temperatures at the hot water
outlet. A tempering device is recommended in the hot water
supply line to reduce the risk of scald injury.
Water Heater Sounds
During the normal operation of the water heater, sounds or
noises may be heard. These noises are common and may
result from the following:
1. Normal expansion and contraction of metal parts during
periods of heat-up and cool-down.
2. Condensation causes sizzling and popping within the
burner area and should be considered normal.
3. Sediment buildup in the tank bottom will create varying
amounts of noise and may cause premature tank failure.
Drain and flush the tank as directed under "Draining And
Flushing".
Smoke/Odour
The water heater may give off a small amount of smoke and
odour during the initial start-up of the unit. This is due to
the burning off of oil from metal parts of a new unit and will
disappear after a few minutes of operation.
Anode Rod/Water Odour
Each water heater contains at least one anode rod, which
will slowly deplete while protecting the glass-lined tank from
corrosion and prolonging the life of the water heater. Once
the anode is depleted, the tank will start to corrode, eventually
developing a leak. Certain water conditions will cause a
