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 conditions:
•
When a number of similar error codes and/or lockouts appear.
•
At least every 12 moths' maintenance must be done to ensure safe and efficient operation.
Damage caused by lack of maintenance will not be covered under warranty.
3 Water quality (also see § 8.1)
Water supply quality may adversely affect the efficiency performance and longevity of Water Heaters and Hot
Water systems. Hard water may cause the formation of lime scale which will reduce operating efficiency and may
cause early product failure. Please note the following:-
•
Hardness should not exceed 196 PPM CaCO
hardness up to 250 PPM (14 °dH or 17.5 °Clark) is acceptable.
•
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 should 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 these values are exceeded a water treatment specialist should be consulted. Water Softeners and Water Condi-
tioners may be considered, but whichever method is selected, it should be suitable for installation with Direct Gas-
fired Water Heaters. A maintenance regime will also be required for such systems.
The formation of lime scale or other solids can cause a blockage within the heat exchanger, which in turn
may cause premature failure. Such instances are not regarded as defects in manufacture and will not be cov-
ered under the product warranty.
