Page 38: Air Supply
11.0 AIR SUPPLY The following information is based on single water heater installations only. If more than one water heater is being used, BS5440-2 or BS6644 (as appropriate) should be consulted to calculate the necessary requirements. 11.1 COMBUSTION VENTILATION When used as a Type C (room sealed) appliance, provided sufficient clearance is provided, ventilation for combustion is not necessary as the combustion air is ducted directly from outside. -
Page 39: Water Connections
The requirements of minimum water flow are given in Table 12.4.1. Recommendations for the water circulation system are given in BS6644 and CP 342. The following notes are of particular importance. EcoKnight™ must be used with a direct type storage vessel (LST). Contact Lochinvar Limited for help in sizing the storage vessel. -
Page 40: Open Vented System Arrangement
UN-VENTED SYSTEM ARRANGEMENT If the Lochinvar EcoKnight™ is to be used in an unvented arrangement, the system should follow the guidance given in BS6700 and must comply with The Building Regulations: Part G3 in England and Wales, P5 in Northern Ireland and P3 in Scotland. A kit of components that have been suitably sized for the unvented or boosted operation of the appliance is available from Lochinvar Limited. -
Page 41: Circulating Pumps
In order to ensure the correct flow rates through the water heater, the unit requires a bronze glanded pump sized to overcome the resistance of the heat exchanger and a primary pipework loop. Lochinvar will supply a suitable bronze glanded shunt pump with each water heater as shown in Section 12.4.1. -

21.4.2 TANK SET POINT DIFFERENTIAL When a tank sensor is installed, the tank temperature must drop this amount below the tank set point (DHW Tank Set point parameter) before the water heater turns back on. The installer can adjust this setting by accessing the Tank Set point Differential parameter. - Page 77 21.6.3 MAXIMUM CASCADE SET POINT This parameter determines the set point used by the individual water heaters in a Cascade when a system sensor is connected to the Leader water heater. When a water heater is commanded to fire by the Leader water heater, it will attempt to achieve this temperature at its outlet.
