7. Monthly drain off a gallon of water to remove silt and
sediment. WARNING! This water may be HOT.
8. All models are equipped with a cleanout opening to aid in
removal of hard water deposits from the tank bottom. If this
water heater operates under hard water conditions, the
following should be performed at least every 3 months:
Drain the water heater. Remove the cleanout jacket cover
and tank cover. When cleaning the tank, care must be taken
to avoid trying to break deposits loose as this could damage
the glass lining and shorten the life of the water heater. After
cleaning, replace the cleanout tank cover and jacket cover,
and refill with water.
9. A sacrificial anode rod has been installed to extend tank
life. The anode rod should be inspected annually (every
year) and replaced when necessary to prolong tank life.
Water conditions in your area will influence the time
interval for inspection and replacement of the anode rod.
Contact the plumbing professional who installed the water
heater or the manufacturer listed on the rating plate for
anode replacement information. The use of a water softener
may increase the speed of anode consumption. More
frequent inspection of the anode is needed when using
softened (or phosphate treated) water. However, the new
models have Correx anodes that do not require inspection or
replacement.
10. The venting system must be inspected at least once a
year to ensure against leakage of exhaust products.
Caution
FOR YOUR SAFETY, DO NOT ATTEMPT REPAIR OF
COMBINATION GAS CONTROL, BURNERS OR GAS
PIPING. REFER REPAIRS TO A QUALIFIED SERVICE
TECHNICIAN.
Servicing must be carried out by a properly qualified
person.
Whilst giving these instructions for the care of the ECOflo, it is
recommended that checks are carried out by the installer or
local gas service engineer at least annually. Ensure good
ventilation by keeping the heater free of extraneous materials
and clear of dust and lint. Keep pipework, flue and tops of
heaters clear of any combustible materials. A water softener or
scale inhibitor should be employed in hard water areas. The
heater should be inspected every few months via the hand hole
cleanout and scale or silt deposits removed. Failure to do so will
shorten heater life and may invalidate the warranty.
Before servicing, carry out the following operations.
1. Turn off the gas service cock.
2. Turn off the cold water supply to the heater.
3. Turn on the hot water draw-off taps served by the water
heater, or, for multiple installations, turn off the hot water
outlet connection valve and secondary return valve.
4. Drain down using the drain valve on the heater.
