Zip hydrboil plus

[kooltech]

Hi
I have been asked to install some Zip Hydroboil plus wall mounted units in our office.

it seemed simple enough .................. but I didn't realise they required a vent pipe.

Only options I have is to vent it direct to outside - but was worried about it possibly discharging boiling water, or take it in to the under sink waste - but not sure of the best way of doing that? Had thought abount simply venting in to the sink - but thought that would look a bit naf.


Any advice much appreciated

) Venting
A vent at the base of the heater must be plumbed to a safe visible location as, under certain conditions, it may discharge cold or boiling water and/or steam.
For exposed vent plumbing, connect vent outlet from the base of heater to a 15 mm or half inch OD pipe which has a continuous fall, is no more than 3 metres long, has no more than 3 right angle bends, and discharges to a waste water drain.
For concealed vent plumbing, connect plumbing to the vent outlet from the heater rear using a capillary elbow protruding 45 mm from the wall.
Alternatively attach a tun dish to the wall as shown and plumb away to waste.

this is from the m.i

thanks APP.

I read that - but wasnt sure how to connect it to a drain? I presume that it has to be via some sort of trap to prevent smells coming up the pipe, but wasnt sure what type of trap ? wasn't sure if I could just connect it to appliance inlet on sink trap?

Ours has a 15mm CP pipe discharging into the sink. Most of the ones I've seen are like that. No issues with drain smells or having to put a tundish in to give visible discharge.
