WATER QUALITY
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 limescale 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.

LOCATION
8.1
PLANT ROOM REQUIREMENTS
The Lochinvar EcoShield™ may only be installed in a room that complies with the appropriate ventilation requirements.
The Lochinvar EcoShield™ can be used as a type C
13
, C
33
, or C
53
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 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 or to
comply with the recommendations in BS6644, 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 EcoShield™ can also be used as a type B
23
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 9 AIR SUPPLY or to BS5440-2 or BS6644 as appropriate.
8.2
GENERAL REQUIREMENTS
Corrosion of the heat exchanger 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 a suitable drain pan should be installed under the equipment. The pan should
be adequately drained but must not restrict the combustion or ventilation airflow.
8.3
CONDENSATE DRAIN
The condensate drain is located on the left hand side of the water heater. It is fitted with a ½” PVC tee and union, this should be connected to
an appropriate condensate drain, sloping continuously away from the water heater at an angle of at least 3
(50mm per metre).
The Water Resources Act requires that trade effluent is discharged to municipal sewers between pH 6.5 and 10.0. If it is determined that these
levels cannot be achieved, an in-line condensate neutralisation kit is available from Lochinvar Limited. This unit is capable of neutralising 4000
litres of condensate to a pH of 7.0 before releasing it to a drain.
