Using a spirit level, tape the GasSaver and
PremierPack templates to wall. Mark all positions as
indicated on wall, drill holes and add rawlplugs. Mark
flue position and drill hole.
Screw PremierPack, GasSaver hanging bracket and
top fixing bolt assembly to wall.The boiler and
GasSaver can now be simply hung whenever you are
ready.
Drill hole in wall and push Expansion Relief Valve pipe
through. Pull back so that the rubber grommet
completes a seal, mark off and cut to required length.
Remove tails from boiler and screw to PremierPack.
Measure, cut, bend and fit GasSaver mains inlet/outlet
pipework to PremierPack using the pipe clip plate.
Complete any other necessary pipework and fit using
pipe clips where required.
Complete an
y solder
ing that is necessary Position thermal store where required, and fit
washers plus tails to connections shown on pipework
label on top of store

Its thermal store recharges in just 5-7
minutes, compared to the 45 minutes a
200 litre cylinder can take to replenish
from empty.
The small thermal store takes up much
less space than a cylinder, enabling
FlowSmart to be more easily sited. If
required, the entire system can even be
installed together in a cupboard.
This, along with a limited pipework
requirement, means installation of
FlowSmart is also quicker and simpler.

ESS GAS USED*
F
lowSmart uses up to 25% less gas to provide DHW than a system boiler with a 200 litre unvented store
a
nd consumes less electricity.
By incorporating a GasSaver and small thermal store, FlowSmart allows a combi boiler to deliver a flow rate of 18
litres of hot water per minute, at 50ºC or above, for up to 30 minutes – more than three times longer than a typical
system boiler set-up.Together with its superior energy efficiency and ease of installation, this makes FlowSmart the
perfect combination.

How FlowSmart works
When there is a demand for DHW, mains cold water flows into the GasSaver, where its temperature is raised using
heat reclaimed from boiler flue gases.

This pre-heated water then passes
through a copper coil heat exchanger in
the thermal store, where it is heated
further by surrounding hot water from
the primar
y system.
The water then passes thr
ough a
blending valve, where it is controlled to
30ºC, before entering the boiler.
With less work to do to raise the
water’s temperature, the boiler is able
to satisfy heavy DHW demands for long
periods, without detrimental effect to
flow rate.
