STEP 4 STEP 5 STEP 6
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.
Removetails 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 anysoldering that is necessary Position thermal store where required, and fit
washers plus tails to connections shown on pipework
label on top of store

FlowSmart system v 200L unvented cylinder at flow rate 18 litres/minute
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
FlowSmartis also quicker and simpler.
25
%
LESS GAS USED*
FlowSmart uses up to 25% less gas to provide DHW than a system boiler with a 200 litre unvented store
and 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.

Lift boiler on to PremierPack and fasten connections
from PremierPack to boiler.
Fit GasSaver flue clamp and lower GasSaver on to
flue turret. Secure GasSaver using top fixing bolts and
adjust to level.Tighten screws on GasSaver flue
turret.
Connect the pipework to GasSaver and fit flue pipe.
Position and fit junction box, fuse spur, 2-channel
timer and room thermostat.
Removethermal store thermostat panel. Cut
insulation material as required and remove. Wire up
cylinder thermostat and fit into cut hole and secure
using the fastening supplied.
Lower boiler control panel and removeterminal
block cover. Replace 3-core power chord with 4-core
cable to provide a switched liveconnection at
terminal one.
Replace terminal block and cover, push control panel
back into place and screw down. Fit pipe cover tray
to complete installation.
Adjust all settings on controls, thermostats and timers
according to installation instructions and homeowner’s
requirements. Commission the system, carefully
following the commissioning guidelines provided.
Completed installation.
STEP 7 STEP 8 STEP 9
Install blending valve between mains water supply
and hot outlet of thermal store.The blended outlet
connects to the boiler cold water inlet.
Fit expansion vessel to primary return pipe of
thermal store, using the compression T-piece
provided.
Fit Y-Plan mid position valve to primary flow, thermal
store primary inlet connection and heating circuit.

CD35C boiler
Acompact SEDBUK ‘A’ rated
condensing boiler with fully-modulating
output of up to 35kW.
GasSaver
Captures and stores heat from boiler
flue gases, using it to pre-heat cold mains
water before it enters the boiler.
Thermal store
Uses heat from the primary system to
further raise the temperature of the
water pre-heated by the GasSaver.
What’s included
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 primarysystem.
The water then passes through a
blending valve, where it is controlled to
30ºC, before entering the boiler.
With less work to do to raise the
water’stemperature, the boiler is able
to satisfy heavy DHW demands for long
periods, without detrimental effect to
flow rate.
