- Water flow velocity and pipe diameters and lengths
The arguments that hold for pump selection, hold for piping design as well: all piping components added up
are giving a certain total resistance which should not exceed a critical value at which the pump cannot realize
the required flow velocity anymore.
Following the instructions and recommendations given in the referred paragraphs will highly improve the function-
ing and considerably lengthen the life time of your HW system.
Furthermore, for all Eco Heating Systems appliances the next instructions and recommendations apply:
! Never use aluminum or aluminum containing flue gas outlet parts.
! Always fill the siphon before commissioning the water heater
! Always set the gas valve during commissioning of the water heater, for the first time and after maintenance
and/or installation changes
! Never place a (ball) valve between the safety valve and the water heater
! In a log, keep track of all situations regarding the appliance:
what, when, by whom, what actions and/or changes, what communication has been performed
Eco Heating Systems is not liable for any damage caused by inaccurately following these instructions. Only Eco
Heating Systems parts may be used when carrying out any repair or service works.
Do not use chlorine based products for brazing. When commissioning the water heater, the running of the water
heater pump must be checked before leaving the installation.
Firing the water heater without water flow (but filled with water) will cause a boiling noise and can damage the heat
exchanger.
The Outlet and Inlet temperature are checked continuously. The temperature difference may not exceed the pro-
grammed value belonging to the actual power mode. If it does, the water heater will go in a lock-out.
The applied DHW pump must be controlled only by the HW water heater control. If, for any reason, an
external pump control is applied
without written approval of Eco Heating Systems , the complete war-
ranty on the HW water heater and all supplied parts will become invalid.
Minimum water pressure 1 bar.
Fuel used should have sulfur rates that comply with the next values: a maximum annual peak over a short period
of time of 150 mg/m
3
and an annual average of 30 mg/m
3
maximum.
Combustion air must be free of contents of chlorine, ammonia and alkali agents. The air near a swimming pool, a
washing machine or a laundry is containing these ammonia contents.
If the water heater is used in combination with a hot water tank without any other heat exchanger; the water heater
should be equipped with a safety relief valve. In some cases also the tank should be equipped with a T&P relief
valve. Always apply all applicable installation standards and regulations.
At first installation, the built-in automatic air vent should be open.
LEGIONNAIRES’ DISEASE
An anti-Legionella function is present in the software and is default turned ON. See this manual for the program-
ming options.
