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.

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.

GAS SUPPLY

The Lochinvar EcoKnight™ range is suitable for use on second and third family gasses 2H - G20 - 20mbar and 3P - G31 - 37mbar.
Details relating to Natural Gas (2H) appear below; for details relating to Propane (3P) please refer to Section 18.0: LPG FUEL.

SERVICE PIPES

The local gas distributor must be consulted at the installation planning stage in order to establish the availability of an adequate
supply of gas. An existing service pipe must not be used without prior consultation with the local gas distributor.

METERS

A new gas meter will be connected to the service pipe by the local gas distributor contractor. An existing gas meter should be
checked, preferably by the gas distributor, to ensure that it is adequate to deal with the rate of gas supply required.

GAS SUPPLY PIPES

Supply pipes must be fitted in accordance with IGE/UP/2. Pipework from the meter to the equipment must be of adequate size. The
complete installation must be purged and tested as described in IGE/UP/1. Refer to Section 18.0.LPG FUEL for information on
LPG pipework installation guidance.

BOOSTED SUPPLIES

Where it is necessary to employ a gas pressure booster, the controls must include a low-pressure cut-off switch at the booster inlet.
The local gas distributor must be consulted before a gas pressure booster is fitted. For details of how to connect a low-pressure cut-
off switch, please refer to Section 15.5.2

PLANT-ROOM CONTROL VALVE

A manual valve for plant-room isolation must be fitted in the gas supply line. It must be clearly identified and readily accessible for
operation, preferably by an exit.

EQUIPMENT GAS SYSTEM LEAK CHECK

An approved gas-inlet appliance isolating valve and union should be installed for each unit in a convenient and safe
position and be clearly marked. Ensure that the gas-inlet appliance isolating valve is in the OFF position. Although the equipment
receives a gas leak check and gas train component integrity check prior to leaving the factory, transit and installation may cause
disturbance to unions, fittings and components. During commissioning a further test for tightness should be carried out on the
equipment gas pipework and components.
Care must be taken not to allow leak detection fluid on or near any electrical parts or
connections.
