Q. You'd have to agree wouldn't you that there is a real risk that if the window is open products of combustion from the heater will go in the window?
A. I would argue the point, no I don't think that would be the case. As I drew in my drawing earlier, the gasses act - it's hot air, it gets ejected from the water heater probably to about I'd say about four metres, under force, and then it rises. Now if a window is higher probably say two or three metres higher, it's going to eject out four metres and have more of a chance of drifting up isn't it? In my opinion, this is just my opinion, I would never do it because I've got to literature to back it up, but if that window was directly above that flue it would probably be safer, because the fumes would be ejected out no into the atmosphere and they would drift off. And I just must add, this window that was above it, according to the statement and according to what I remember, had a six inch gap. You'd have to have a hell of a prevailing wind to shove it up that window.
Q. Now, at 37 Dommett Street, or avenue, as a precaution you arranged you say, for the customer to screw the window shut?
A. As it was a bedroom.
Q. Surely if it's - if you need to do that when it's a distance of 1340 millimetres, you'd also want to do that when there's only 500 mm metres?
A. Did you listen to what I just said? Did you comprehend what I was just saying? I believe that a heater - a window higher - you've got more room for that forced out air to return back. In a smaller distance and I believe that I was complying with the tech note I have, which wasn't for a Bosch, but if I took the guts out of that unit and put it in a Rinnai unit, you wouldn't know. The - I made a judgment call, I believe borne out by it - I've been borne out by it. The customer said it's never been a problem. I distinctly remember ringing Colleen Singleton and I asked her for advice where to turn for any information, advice. She told me to refer to industry providers and industry member. I can only do what I'm told. I can only follow instruction. If my boss gives me something from a reputable firm I can ________________________________________________________________________ 392
only - why would I have kept that original fax? Because I thought it was relevant to my job and I thought it helped me perform my job better. I could have said to this guy "oh that unit mate got to go about 20 metres up the wall, it will cost you a bit extra in the plumbing and gas and all this", I tried to put if as near as I could to his bathroom, he's happy, there's no problem with fumes coming in. I made the call, my call and the tech note have been borne out to comply with Part 1 of the regular which is mandatory. Part of the 2 of the regs, is according to the regs, I'll have a look here, at the beginning - I can't be bothered looking it up, I know what it says, it says Part 1 is mandatory; Part 2 is a way - an acceptable solution for it to conform, it also mentions in there to reference of the regs, it tells you to - I've never seen a document so hard to understand and contradictory, what would you say if I could say I could point out what I think is an error in that document? Would you be interested in any of that? No? Won't bother.
Q. Okay now we'll move on to 5 Powick Street.
A. Yeah.
Q. And could you please go to paragraph 105 in your statement at tab 15. Tab 15, your statement, 105. Now you said that all you did there was to re-run the pipe to the califont that is from an existing supply to an already installed unit, not units?
A. Yep. That's singular.
Q. Yes. Now it's my understanding then that what you are saying that was to re-run the pipework from the existing Rinnai 32 upstairs?
A. No not from it, to it.
Q. Okay to it, from the existing bottles?
A. Yeah. Yep, that's what I'm saying.
Q. And do you say that at that stage the other Rinnai that was getting installed - or has been installed as we see in the photos wasn't there?
A. Has been since installed there. It was still in bits on a Japanese production line when I did the job.
