FLUES
UNIQUE INSTALLATION BENEFITS
WITH PLASTIC FLUE
A small diameter (50mm) muPVC standard
kitchen waste pipe is the sole requirement for the
innovative new flue and air intake system. Vertically
or horizontally, the flue can be extended up to 20
metres from the boiler allowing for easy and hassle-free
installation, and up to 60m using 70mm Keston composite
flue. The boiler can therefore be sited in the most
convenient and practical locations.
The standard
muPVC waste pipe is a fraction of the cost of conventional
flues and is available from
all Builders merchants- therefore no more waiting
days for traditional flue system extensions.
5 FLUE Q&A
| Q: |
Does Keston really use standard
kitchen waste pipe for its flueing system? |
| A: |
Yes – we use standard 50mm muPVC kitchen
wastepipe (BS 5255), available from builders’ and
plumbers’ merchants at around £1
per metre. |
| Q: |
Is there a maximum number of bends that I can
use? |
| A: |
You are limited by the flue length required.
For longer lengths you can select the Keston
composite flue system. |
| Q: |
Does each tube need to be the same length? |
| A: |
No. You can draw air for combustion from one
source and the flue products go elsewhere. |
| Q: |
How long can I run this flue system? |
| A: |
Maximum length for standard 50mm wastepipe
is 20m, vertically or horizontally. Our composite
flue extends up to 60m. |
| Q: |
If I run the flue vertically to avoid pluming,
can I draw the combustion air from the ground
floor? |
| A: |
Yes. |
