Wiring and Heating

Spent the last couple of days down at T-A, cutting through steelwork to run the ducting for the un-fused 12v and 240V supplies. There will be conduit from the batteries for the supply to the trip switch panel and a further lead to the control desk for the supply to the fused bilge pump switch. This should make things comply with ISO 10133 setion 8.1
Quite a bit of the work will take place below in the engine ‘ole so I decided it was time to move the Hurricane heater. To make sure the heater was being moved to a suitable location I have studied the Hurricane manual downloaded from the internet.
It states that the unit should be installed with:-
Access to front. top and left hand side for maintenance.
Secured by four bolts.
Fitted with an expansion tank and header tank.
Exhaust to be supported every 3’ minimum.
Exhaust and air pipes should include a goose neck to prevent water ingress.
Exhaust must have 3” clearance from all surfaces.
Fuel supply should be by flow and return pipes.
Fuel line should be fitted with in line filter.
Water pump must be mounted lower than the boiler.
“The engineer has been out and says the installation is perfect, there is no reason why it should be giving problems” – Yeah right!
Not to mention that the broken inlet manifold listed during the build was never replaced just bodged with black tape.
Once the wiring has been sorted down there it will be time for another proper job.

The guys at Calcutt told us that the requirement for 3' goosenecks in the air intake and exhaust pipes could be ignored in a narrowboat that doesn't expect to encounter serious seas, which makes life a good deal easier!

Keep up the good work

All the best

Hi Bruce

Yes I agree with that but shall include a small bend to prevent any moisture/condensation running back into the heater. I shall be urgently checking the builders manual if I find us heeling over under full sail:-)
