7.3 Clearances (Figs. 15 &16)
1. These dimensions include the necessary clearances
around the boiler for case removal, spanner access and air
movement. Additional clearances may be required for the
passage of pipes around local obstructions such as joists
running parallel to the front face of the boiler. For side flue
installations also See Section 8.1, Figs. 20 & 21.
2. It is recommended that any worktop is removable for
servicing access.
7.4 Gas Supply
1. Check that the information concerning the state of
adjustment given on the data plate is compatible with local
supply conditions.
2. The gas installation should be in accordance with the
relevant standards. In GB this is BS 6891. In IE this is the
current edition of I.S. 813 “Domestic Gas Installations”.
3. The connection to the boiler is a 15mm tail on the gas
service cock. The tail protrudes through the boiler rear
panel and is protected by a transit bracket which may be
removed to aid connection.
4. Ensure that the pipework from the meter to the boiler
is of adequate size. (If the boiler is further than 3 metres
from the Gas Meter 22mm pipe should be used). Do not
use pipes of a smaller diameter than the boiler gas
connection.
7.5 Electrical Supply
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 ETCI rules.
2. The mains supply is 230V ~ 50Hz fused at 3A.
NOTE: “The method of connection to the electricity
supply must facilitate complete electrical isolation of the
appliance and system”.
Connection may be via a fused double-pole isolator with a
contact separation of at least 3mm in all poles, which must
be in an accessible position to the user and serve the
boiler and system controls only.
There is no method of isolating the boiler at the user
interface.
3. Four core cable is required to supply the boiler as a
permanent live is necessary for the operation of the
condensate pump and frost protection.
