7.0 WATER QUALITY
7.1 WATER QUALITY /HARD WATER
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: -

Water Hardness – should not exceed 205ppm CaCO3 and Total Dissolved Solids (TDS) of untreated water should not
exceed 350ppm.
If these values are exceeded a water treatment specialist should be consulted. Water Softeners and Water Conditioners
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

High hot water temperature and high demand for hot water is likely to cause quicker limescale formation
The formation of limescale 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
covered under the product warranty.

8.0 LOCATION
8.1 PLANT ROOM REQUIREMENTS
The Lochinvar EcoKnight™ can only be installed in a room that complies with the appropriate ventilation requirements.
The Lochinvar EcoKnight™ can be used as a type C
13
, C
33
, C
43
or C
53
(room sealed) appliance. Due to its room-sealed design,
ventilation allowances for combustion air are not necessary, provided the minimum clearances and service clearances as detailed
in 5.2.2 are observed. If the appliance is to be installed in a compartment or a hot environment, the minimum clearances detailed in
5.2.1 should be observed. In addition to this, ventilation for cooling purposes must be fitted. For further guidance, please refer to
Section 11.0 or to BS5440-2 or BS6644 as appropriate.
The Lochinvar EcoKnight™ can also be used as a type B
23
(open flue) appliance. If such a configuration is to be used, then
appropriate ventilation for cooling and combustion must be provided. For further details, please refer to Section 11.0 or to BS5440-
2 or BS6644 as appropriate.
8.2 GENERAL REQUIREMENTS
Corrosion of the heat exchanger coils and flue system may occur if air for combustion contains certain chemical vapours. Such
corrosion may result in poor combustion and create a risk of asphyxiation. Aerosol propellants, cleaning solvents, refrigerator and
air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes and process chemicals are corrosive.
Products of this sort should not be stored near the water heater or outside by the air intake (if applicable). The fitting of this equipment
in a situation where aerosols or other chemicals may be entrained into the combustion air will invalidate the warranty.
The equipment must be installed on a level surface that is capable of adequately supporting its weight (when filled with water) and
any ancillary equipment. The operation of the equipment must not cause the temperature of any combustible material in the vicinity
of the equipment and its flue to exceed 65°C. If such a situation is unavoidable, appropriate insulation should be provided.
Locate the equipment so that if the appliance or any connecting pipework should leak, water damage will
not occur. When such locations cannot be avoided it is recommended that a suitable drain pan be installed
under the equipment. The pan should be adequately drained but must not restrict the combustion or
ventilation airflow.
8.3 CLEARANCES
The location chosen for the equipment must permit the provision for a satisfactory flue system and, where necessary, an adequate
air supply. The location must also provide adequate space for servicing and air circulation around each unit. This includes any
electrical trunking laid across the floor and to the appliance.
See Section 5.2.1 DIMENSIONS/CLEARANCES. Further details regarding locations are given in BS5440 or BS6644 as
appropriate.
