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.

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.

STEP 1

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.

STEP 4

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.

STEP 2

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.

STEP 3

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.
