5.0Site Requirements
5.6Ventilation
1.No ventilation is required for the boiler in the room of installation.
5.7Gas Supply (Fig. 11)
1.The gas installation should be in accordance with relevant standards. In GB this is BS 6891. In IE this is I.S.
813“Domestic Gas Installations”. The connection at the appliance is 15mm copper tail located at the rear of the gas tap.
2.Ensure the pipework from the meter to the appliance is of adequate size. It is necessary to route the gas supply pipe to the right hand side of the builders opening. It must be routed so as not to restrict the installation and servicing of the appliance.
5.8Electrical Supply (Fig. 11)
1.External wiring must be correctly earthed, polarised and in accordance with relevant regulations/rules. In GB this is the current I.E.E. Wiring Regulations. In IE reference should be made to the current edition of the ETCI rules. The mains supply is 230V ~ 50Hz fused at 3A.
NOTE: The method of connection to the electrical supply must facilitate complete electrical isolation of the appliance. Connection may be made via a fused double pole isolator with a contact separation of at least 3mm on all poles and serve the boiler and system controls only. The boiler MUST NOT be connected to the same supply as the firefront as their fuse ratings are different and subsequent damage may occur.
2.The boiler supply cable within the builders opening should be 0.75mm2 to IEC 53 code 227 (heat resistant).
3.It is preferable to route the electrical supply cable to the right hand side of the builders opening. If however it must come from the left hand side it must be routed so as not to restrict the servicing of the appliance.
4.The cable must be routed to avoid contact with any part of the boiler.
