If more than one water heater is being used, BS6644 should be consulted to calculate the necessary requirements. 11.1 COMBUSTION VENTILATION When used as a Type C 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
OPEN VENTED SYSTEM ARRANGEMENT The Lochinvar EcoShield™ can be used in an open vented arrangement provided that a vent pipe in accordance with CP 342, BS6644 or BS6700 as appropriate is fitted. The minimum static head requirement for an open vented system is 1.0 bar. -
Page 40: Unvented System Arrangement
It is the law that unvented hot water systems be installed by an approved installer. If the Lochinvar EcoShield™ is to be used in an unvented arrangement, the system should follow the guidance given in BS6700 and must comply with the Building Regulations 1992: 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 operation of the appliance is available from Lochinvar Limited. - Page 41 TEMPERATURE AND PRESSURE RELIEF VALVE A temperature and pressure relief valve is factory fitted as part of the unvented water system kit. This valve has a lift pressure of 7 bar and a lift temperature of 90°C. This should be checked for transit damage prior to filling the water heater. The storage vessel relief valve connection should not be used for any other purpose.

14.3 SEQUENCE OF OPERATION Operation Display 1. Upon call for heat the control turns on the integrated pump. 2. The control connects 230 VAC to the fan. The fan does not run at this time. If the unit is equipped with a low water cut-off, it must be closed before the control powers up the fan. - Page 50 5. If the control does not detect flame by the end of the trial for ignition, the control performs a 10 second post-purge. On the SHW35 CE to SHW116 CE models, the control will perform another pre-purge and try to light the burner again. If the burner does not light after 4 trials, the control will lockout for 1 hour and then try another set of 4 trials.
