To ensure that the flow and return pipes will pass through the cut-
outs provided in the top and bottom of the case all pipes should be routed as s
hown in FIGS.
10a
,
b
. Ifrequired a 22mm copper pipe can be routed down eac
h side of the boiler within the casing.
Install a drain-off tap close to the boiler if it is in a low point of the system.
For combined gravity DHW and pumped CH systems an injector tee has been
provided to ensure correct circulation in the gravity circuit. This must be conn
ected to theboiler as shown in
FIG. 10a.
The gravity circuit should be installed
using 28mm copper pipe with the flow increased to 28mm as close to the boile
r connection as possible.
On fully pumped systems the injector tee is not required and should be discar
ded. The flow and return must be connected to the pumped tappings on the b
oiler and thegravity flow tapping should be capped off, or may be used as an o
pen vent connection.
Route the gas supply pipe from below the boiler and connect it to the inlet con
nection of the gas cock.
