WATER QUALITY
Water supply quality may adversely affect the efficiency and performance of water heaters and hot water systems.
The situation can intensify where higher temperatures or demands exist.
Water hardness should not exceed 205ppm CaCO
not exceed 350ppm. If these values are exceeded, contact Lochinvar Limited for further guidance.

LOCATION
6.1 PLANT ROOM VENTILATION
The Lochinvar Mini Copper-Fin may only be installed in a room that complies with the appropriate ventilation
requirements. For further details, please refer to Section 9: AIR SUPPLY or to BS5440-2 or BS6644 as
appropriate.
6.2 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, non-combustible 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.
6.3 CLEARANCES
The location chosen for the equipment must permit the provision for a satisfactory flue system and 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 Figure 3.1 and Table 3.1 for dimensions and clearances. Further details regarding locations are given in
BS5440 or BS6644 as appropriate.
