Important technical warnings and guidelines
Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
Maintenance and inspection of the water heater should be carried out at the following occasions:
•
When a number of similar error codes and/or lockouts appear.
•
At least every 12 months maintenance must be done to ensure safe and efficient operation.
Damage caused by lack of maintenance will not be covered under warranty
The Eco King Hot Water systems will, for a long period, comfortably meet your requirement of hot water of the
right temperature at the right hour, provided that a few important conditions have been fulfilled regarding the in-
stallation.
Please follow all instructions and recommendations presented in this manual by Eco king, especially the ones
concerning the next important topics:
-
Water quality (also see §6.7 on page 29)
A first necessary condition is the quality of the water to be heated in the hot water heater.
Only potable water can be used with this water heater. Do not introduce pool or spa water, or any chemically
treated water into the water heater.
Three values matter: hardness, total amount of dissolved solids and acidity. If water quality does NOT meet
the requirements the system may be seriously damaged in time!
♦
Hardness should not exceed 205 PPM CaCO
3
(11,5°dH)
Water hardness leads to scale formation and may affect/damage the water heater. Hard water scaling
must be avoided or controlled by proper water treatment.
♦
TDS (Total Dissolved Solids) should not exceed 450 PPM
♦
Hardness and TDS together may not exceed 450 PPM
♦
pH value should be between 6,5 and 7,5, measured cold
The actual values can be retrieved at your local water supplier.
If water quality doesn’t meet the abovementioned requirements, a water treatment installation should be in-
stalled to improve water quality to the required levels, if possible.
- Water flow velocity and pump selection
For a given combination of water heaters and tanks, pump selection is very important with respect to the
required flow velocity.
- Water flow velocity and piping diameters and lengths
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 King appliances the next instructions and recommendations apply:
! Never use aluminium or aluminium containing flue gas outlet
!
Always fill the siphon before commissioning the water heater
!
Always set the gas valves during commissioning 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 King is not liable for any damage caused by inaccurately following these mounting instructions.
Only Eco King 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 leav-
ing the installation.
