joining heating exhaust

[john]

I have three one metre lenghts of exhaust pipe for a wallas heater, and rather than buy a 3 metre length I would like to join my metre lengths together. What is the safest way to do this?
BTW does anybody have any wallas heater spares?
thanks

A friend has joined heater exhausts with a sleeve of sheet aluminium, wrapped around, some sort of gasket gunk underneath, then hose clipped. It's worked for the last 3 years and he hasn't killed himself yet. He does , however, have a carbon monoxide detector in the cabin.

Go to the supermarket - find some cans of the right diameter - eat the contents - cut off other end of can and hey presto a connector.

Have a look at Case 26 from the MAIB's latest safety digest...

Carbon monoxide (CO) is a very toxic gas and in the period Jan 03 to Feb 04 there were at least five deaths in four incidents from CO poisoning on inland waterways. Questions of the effectiveness of the flueing arrangements were probably a factor in three, running a petrol generator in the cabin space was the fourth.

Medical opinion on both sides of the Atlantic suggests that there may be serious consequences from long-term low-level exposure. Furthermore, death can happen very quickly to vulnerable people even with moderate levels of CO.

Hence a recommendation to seek advice from the manufacturers or suppliers instructions about your model of heater as to;
a) what is the maximum effective exhaust length, and,
b) what is needed to make a safe and effective joint, if jointing is recommended.

The eberspasher (or something spelt sightly similar) recomend maximum exhaust legths of 2m so I might be concerned about having a 3m exhaust on what really is a very similar system (I think!).

The problem I believe is down to the balanced flue arrangement used on these heaters. This has no bearing upon joining your flue I admit and have you considered visiting a stainless fabricator and asking them to weld the bits together, I had a similar length weld done on one of my crosstrees, albiet cash work, cost me a whole £5.00.

Might be worth asking and might turn out cheaper than gun gum, tubes and 6x stainless jubilee clips?
