Fitting valve pack
Remove plastic caps from boiler connection
and fit valves as per fig. 29 using the washers
provided.
It is recommended fitting the valve pack
before installing the boiler on the wall.
5.21
GAS CONNECTION (Fig. 29)
A minimum working gas pressure of 20 mbar (8
in w.g.) must be available at the boiler inlet at
full flow rate (37 mbar for propane).
(Also see section 4.6)
Fit the gas service cock to the boiler via the
Fit the gas service cock to the boiler via the
union nut and connect gas pipe. Do not over

tighten and use another spanner as a counter
force to avoid straining internal connections.
Important consult (sect 4.6).
5.22
CENTRAL HEATING CONNECTION
(Fig.
29)
Before any central heating connections are
made to the boiler all system valves should
be opened and the system thoroughly flushed
out with cold water.
- Connect the central heating return pipe to
the isolating cock.
- Connect the central heating flow pipe
to the isolating cock marked CHF.
- Pipe dimensions and positions are
marked on template supplied (fig. 30).
5.23
DOMESTIC HOT WATER CONNECTION
(Fig. 29)
The domestic hot water circuit does not need
a safety valve but it is essential to ensure that
the pressure of the cold water supply does
not exceed 10 bar. If in doubt it is advisable
to install a pressure reducing valve. The
minimum pressure needed to operate the
domestic hot water system is 0.5 bar with
a flow of approx 3 L
3 L per min. Flush out all
foreign matter from the supply pipe before
and after connecting to the appliance.
- Connect the 15 mm. cold water pipe to the
appliance inlet.
- Connect the 15 mm. hot water pipe to the
appliance outlet.
