Installation

According to Table 6.1 (Page 18) decide if condensation will form

within the flue. If yes, there are two options;

1) Where condense will form but can be negated with insulated

flue, install the insulated flue with a fall of 5mm in every metre

away from the boiler.

2) The exhaust flue will have a fall of 3

and a suitable trap will be fitted on the exhaust as close to the

boiler as possible, condense will then be suitably disposed of.

Where the flue runs through cold spots, i.e. loft areas, condense

is likely to be formed, therefore a fall back to the boiler and a trap

is required.

Always ensure that the flue is adequately supported, avoiding low

points. (MTS supply suitable clamps as Part No. 705778).

To utilise the air intake it is necessary to:

Remove the 'knockout' of the air intake by cutting it with a suitable

knife (F

. 6.16).

Insert the elbow/flue pipe into the air intake until it stops.

The twin flue pipes can be fitted with or without additional elbows

and need no clamps, simply ensure that the red o-ring is insert-

ed in the female end of the flue pipe and push the extension piece

fully into the previous section of flue pipe or elbow, check that the

o-ring is not dislodged when assembling the flue.

Twin pipe can also be converted back to Coaxial flue to enable

vertical termination with a coaxial kit by using the pipe bridge

(Twin - Coaxial Adaptor - Part No. 705767). When running the

twin flue pipe vertically, a condense trap must always be used on

the exhaust pipe.

It is not recommended that the pipe bridge be used for horizontal

termination, however in the unlikely event that this proves to be a

necessity it is extremely important that the entire flue has a fall of

back to the boiler, is suitably trapped and where the 60mm

inner flue of the concentric terminal connects to the pipe bridge,

this point must be adequately sealed with silicone sealant to

avoid condense leakage at this point.

Note: Vertical twin flue installations must have a trap on the

exhaust. MTS supply a suitable condense trap with float

Part No. 705774 and recommend that this be used in the

event that the flue may not form condense.

When siting the twin flue pipe horizontally, the air intake and

exhaust terminals must terminate on the same wall, the centres

of the terminals must be a minimum of 280 mm apart and a max-

imum of 500mm, the air intake must not be sited above the

exhaust terminal (refer to F

run horizontally, however, the terminal and the final 1 metre of

flue must be installed with a fall away from the boiler to avoid rain

ingress.

It is also strongly recommended that the air intake pipe run be

constructed of insulated pipe to prevent condense forming on the

outside of the tube.

The maximum permissible flue length for twin flue is dependent

on the type of run used.
