5.0Site Requirements

5.9Condensate Drain - General

Failure to install the condensate discharge pipework correctly will affect the reliable operation of the boiler.

1.Ensure the discharge of condensate complies with any national or local regulations in force.

BS 6798 & Part H1 of the Building Regulations give further guidance.

2.If any further drain pipe is required (additional to that supplied with the boiler), it should be run in a proprietary material

e.g. PVC, PVC-U, ABS, PVC-C or PP. John Guest ‘Speedfit’ components are recommended.

3.Metal pipework is NOT suitable for use in condensate discharge systems.

4.Any pipe fitted externally must be kept as short as possible to minimise the potential of freezing and must be insulated using waterproof material.

5.When discharging condensate into a soil stack or waste pipe the effects of existing plumbing must be considered.

5.10Condensate Disposal (Fig. 12)

1.This boiler incorporates an automatic pumped condensate system. The pump is submerged in a sump assembly and is activated by the discharge float switch. A second (safety) float switch is fitted.

2.The pump has an effective head of 3.5 metres. The condensate outlet is positioned at the top right front of the boiler. It is 10mm diameter plastic.

 

3. 3.5 metres of flexible 10mm condensate discharge pipe and a

Fig. 12

10mm push fit elbow are supplied with the boiler.

 

 

 

4. The 10mm pipe can be routed to a maximum of 3.5 metres

 

vertically and then discharge via gravity or be routed

 

horizontally. A combination of vertical and horizontal runs is

 

permissible.

 

5. The pipe must be adequately supported, either using suitably

 

spaced clips or run within larger diameter pipe. When using clips

 

take care not to deform the pipe.

 

6. When routing the pipe through a wall it must be suitably

 

sleeved. Also the pipe must not be exposed to sources of heat,

 

and should be protected in locations where it may be damaged.

 

7. The pipe should be routed so that any sharp bends, dips and

 

loops are avoided. A minimum radius of 100mm is

 

recommended for any bends. No slope is necessary and air

 

breaks are not required on the pumped part of the condensate

 

run.

 

8. Any part of the condensate drain system that is outside the

 

dwelling, or in an unheated part of it must be at least 21.5mm

 

diameter.
