5.6 Ventilation
1. No ventilation is required for the boiler in the room of
installation.
5.7 Gas 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.
5.8 Electrical 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 0.75mm 2 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.
