4.1 Cleaning primary systems
Before cleaning the system:
▶ Ensure that the system and pipe work is in good working order.
▶Where possible keep the existing boiler/circulating pump in
place when flushing the system.
Follow the guidance ofBS7593:
Treatment of water in domestic hot water central heating and also the
flushing guidelines below.
Artificially softened water
It is possible to have an ion exchange water softener fitted to the cold
water system of the property. However, the boiler requires an untreated
cold water connection taken from the mains supply, before the water
softener, to the primary water filling point of the heating system.
Alternatively there are water softening/treatment devices that do not
adjust or alter the pH level of the water. With these devices it may not be
necessary to provide an untreated water bypass to the primary water
filling point of the heating system.
Flushing the system
▶ Fill the system with cold water and check for leaks.
▶ Open all drain cocks and drain the system.
▶ Close drain cocks and add a suitable flushing agent compatible with
aluminium at the correct strength for the system conditions in
accordance with the manufacturer‘s instructions.
The pH value of the system water must be less than 8 or the
appliance guarantee will be invalidated.
▶ Circulate the flushing agent before the boiler is fired up.
▶ Run the boiler/system at normal operating temperature as directed
by the manufacturer of the flushing agent.
▶ Drain and thoroughly flush the system to remove the flushing agent
and debris.
▶ It may be necessary to use a power flushing machine to aid the
cleansing procedure in some circumstances.
▶ Close the drain cocks and refill with fresh water and a suitable
inhibitor.
▶ Vent any air from the boiler and system.
Inhibitor
Add a suitable inhibitor or combined inhibitor/anti-freeze, if the system
is exposed to freezing conditions, to the heating system in accordance
with the DWTA code of practice and manufacturer‘s guidelines.

• The meter or regulator and pipe work to the meter must be checked,
preferably by the gas supplier.
4.3 Water systems and pipe work
Plastic pipework:
• Any plastic pipe work must have a polymeric barrier with 600mm
(minimum) length of copper pipe connected to the boiler.
• Plastic pipe work used for under-floor heating must be correctly
controlled with a thermostatic blending valve limiting the
temperature of the circuits to approximately 50 °C.
Primary systems connections/valves:
• All system connections, taps and mixing valves must be capable of
sustaining a pressure up to 3 bar.
• Radiator valves should conform to BS2767:10.
• All other valves should conform to BS1010.
• Thermostatic radiator valves (TRV) must be used on all radiators
within the sleeping accommodation but not the radiator where the

4.4 Condensate pipe work
4.4.1 Internal connections
In order to minimise risk of freezing during prolonged cold spells, the
following methods of installing condensate drainage pipe should be
adopted, in order of priority.
Wherever possible, the condensate drainage pipe should be routed and
terminated so that the condensate drains away from the boiler under
gravity to a suitable internal foul water discharge point such as an
internal soil and vent stack. A suitable permanent connection to the foul
waste pipe should be used.
Fig. 4 Disposal to soil vent stack
Alternatively if the first option is not possible an internal kitchen or
bathroom waste pipe, washing machine waste pipe etc. can be used.
Ensure that the condensate drain pipe is connected “down stream” of
the waste trap.
Fig. 5 Disposal to a waste pipe
Condensate pump
Where “gravity discharge” to an internal termination is not physically
possible, or where very long internal runs would be required to reach a
suitable discharge point, condensate should be removed using a
proprietary condensate pump, of a specification recommended by the
boiler or condensate pump manufacturer.
The pump outlet pipe should discharge to a suitable internal foul water
discharge point such as an internal soil and vent stack, internal kitchen
or bathroom waste pipe, washing machine waste pipe etc. A suitable
permanent connection to the foul waste pipe should be used.
Fig. 6 Condensate pump disposal
NOTICE:
▶ Where a new or replacement boiler is being installed,
access to an internal “gravity discharge” point should
be one of the factors considered in determining
boiler location.
▶ The condensate pipe must be nominally
22mm Ø plastic pipe.
▶ The condensate pipe work must fall at least 52mm
per metre towards the outlet and should take the
shortest practicable route.
▶ Ensure there are no blockages in the pipe run.

4.4.2 External connections
If no other discharge method is possible then the use of an externally run
condensate drainage pipe terminating at a suitable foul water discharge
point, or purpose-designed soak away, may be considered. If this
method is chosen then the following measures should be adopted:
▶ Use a CondenseSure siphon to help prevent the condensate freezing.
▶ The external run be kept as short as possible and not exceed 3
metres.
▶ The pipe should be run internally as far as possible before going
externally and the pipe diameter should be increased to 32mm
before it passes through the wall to the exterior. The pipe should be
insulated using suitable waterproof and weather resistant insulation,
if not using a CondenseSure siphon.
▶ The external pipe should take the shortest and least exposed route to
the discharge point, and should "fall" as steeply as possible away
from the boiler, with no horizontal runs in which condensate might
stand.
▶ The use of fittings, elbows etc. should be kept to a minimum and any
internal “burrs” on cut pipe work should be removed so that the
internal pipe section is as smooth as possible.
Fitting an external air break
• Refer to figure 7 when a rain water down pipe is used to dispose of
condensate.
• An air break must be installed in the 43mm pipe work, between the
boiler condensate outlet and the drainpipe, outside the property, to
avoid flooding during adverse weather conditions.
Fig. 7 Disposal into a rainwater down pipe
Where the pipe terminates over an open drain or gully, the pipe should
terminate below the grating level, but above water level, in order to
minimise “wind chill” at the open end.
The use of a drain cover (such as those used to prevent blockage by
leaves) may offer further protection from wind chill.
Pipe drainage will be improved if the end is cut at 45° as opposed to a
straight cut.
Fig. 8 External disposal
Condensate soak away
• The condensate drainage pipe may be run above or below the ground
to the soak away. The examples shown on this page run above
ground.
• The soak away must use a 100mm Ø plastic tube with two rows of
three 12mm holes on 25mm centres and 50mm from the bottom of
the tube. The holes must face away from the house.
• The tube must be surrounded by at least 100mm of limestone
chippings to a depth of 400mm.
In situations where there are likely to be extremes of temperature or
exposure, the use of a proprietary trace-heating system for externalpipe
work, incorporating an external frost thermostat, should be considered.
If such a system is used, the requirement to use 32mm pipe does not
apply. However, all other guidance above and the instructions for the
trace heating system, should be closely followed.
NOTICE: Freezing conditions
▶ When the position of the boiler prevents internal
routing, we recommend installing a CondenseSure
siphon to significantly reduce the risk of freezing.
▶ Pipe work length should be kept to a minimum and
the route as vertical as possible.
▶ Weather proof insulation must be used, if not using a
CondenseSure siphon.
NOTICE: Condensate waste
▶ Care should be taken when siting a soak-away to
avoid obstructing existing services.

4.8 Flue terminal positions
Fig. 15 Flue terminal positions
Key to illustration
1. 300mm adjacent to a boundary line.
2. The dimension below eaves, gutters, pipes and drains can be
reduced to 25mm, as long as the flue terminal is extended to clear
anyoverhang. External fluejoints mustbe sealed with suitable silicon
sealant.
3. 1,500mm between a vertical flue terminal and a window or dormer
window.
4. 1,200mm between terminals facing each other.
5. Vertical flue clearance, 300mm adjacent to a boundary line unless it
willcause a nuisance.BS 5440:Part 1recommends that careis taken
when siting terminal in relation to boundary lines
6. 600m distance to a boundary line, unless it will cause a nuisance. BS
5440:Part 1 recommends that care is taken when siting terminal in
relation to boundary lines.
7. 600mm minimum clearance from a skylight to a vertical flue.
8. Vertical flue clearance, 500mm to non-combustible building
material, and 1,500mm clearance to combustible building material.
9. 300mm above, below and either side of an opening door, air vent or
opening window.
10.600mm diagonally to an opening door, air vent or opening window.
11.300mm to an internal or external corner. This does not apply to
building protrusions less than 450mm.
12.2,000mm below a Velux window, 600mm above or to either side of
the Velux window.
13.400mm from a pitched roof or 500mm in regions with heavy snow
fall.
14.500mm clearance to any vertical structure on a roof, 600mm to
room sealed flue or 1,500 to an open flue.
15.200mm below eaves and 75mm below gutters, pipe and drains.
16.The dimension below eaves, balconies and car ports can be reduced
to 25mm, as long as the flue terminal is extended to clear any
overhang. External flue joints must be sealed with suitable silicon
sealant.
17.Flue clearance must be at least 300mm from the ground. Terminal
guards must be fitted if the flue is less than 2 metres from the ground
or if a person could come into contact with the flue terminal.
18.600mm distance to a surface facing a terminal, unless it will cause a
nuisance. BS 5440: Part 1 recommends that care is taken when
siting terminals in relation to surfaces facing a terminal.

NOTICE:
▶ All measurements are the minimum clearances required.
▶ Terminals must be positioned so to avoid combustion products entering the building.
▶ Support the flue at approximately one metre intervals and at a change of direction, use suitable brackets and fittings.
(flue bracket 100mm part number: 7 716 191 177,
flue brackets 100mm x 6 part number: 7 716 191 178,
flue bracket 125mm part number: 7 716 191 179).
Note:
▶ Installations in car ports are not recommended.
▶ The flue cannot be lower than 1,000mm from the top
of a light well due to the build up of combustion
products.
▶ Dimensions from a flue terminal to a fanned air inlet
to be determined by the ventilation equipment
manufacturer.
▶ A flue terminal guard should be fitted over a terminal,
if persons could come into contact with the terminal,
or it could be subject to damage and where the
terminalisless than 2,000mm from thefinishedfloor
level.
