STEP 1 STEP 2 STEP 3

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

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.

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.

Return

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.
