2 SAFETY GUIDELINES
“FOR YOUR SAFETY READ BEFORE OPERATING”
WARNING:
Improper installation, adjustment, alteration, service or maintenance can cause property
damage or personal injury. Installation and service must be performed by a qualified in-
staller or service agency (who must read and follow the supplied instructions before in-
stalling, servicing, or removing this water heater).
“A. This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner.
Do not try to light the burner by hand.”
“B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell close to the floor because
some gas is heavier than air and will settle o
n the floor.”
“C. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to
inspect the appliance and to replace any part of the control system and any gas control which has been under
water.”
Without written approval of the manufacturer the internals of the water heater may not be changed. When these
changes are executed without approval, the water heater certification is invalid.
WARNING: Water temperatures over 52 °C can cause severe burns in-
stantly from scalding. The water temperature is factory set at 60 °C be-
cause of legionella prevention. Before bathing or showering always check
the water temperature.
When this heater is supplying general purpose hot water requirements
for use by individuals, a thermostatically controlled mixing valve for
reducing point of use water temperature is recommended to reduce the
risk of scald injury. Contact a licensed plumber or the local plumbing
authority for further information.
This water heater is equipped with a flue pressure switch in the event of a
blocked vent the water heater will lockout. No attempt by the user/owner
should be made to put the water heater back into operation. A qualified
service technician should be notified of the issue. The water heater should only be reset by a qualified service
technician after they have diagnosed and corrected the issue that caused the safety lockout of the water heater.
Eco Heating Systems recommends the installation of a carbon monoxide detector in the water heater room for all
installations.
