Day 086 - 09 Feb 95 - Page 32
1 A. No, the temperature was not raised. They have always
2 been 350.
3
4 Q. It has always been 350?
5 A. Yes.
6
7 Q. So how is it acceptable to have the front of the grill at
8 between 325 and 340?
9 A. OK. This is what I tried to explain yesterday, that
10 with the set-up of a gas grill to ensure that it functions
11 correctly throughout the day, you have to establish that
12 the air flows are working correctly. In doing this at the
13 commencement of business at the beginning of the day, you
14 have to do the check at a certain time. If you have this
15 heat ratio before you have cooked any product on it, then
16 you know that grill will be working correctly. After that
17 if you were to check the grill throughout the day, you
18 would expect to get 350 anywhere on the surface.
19
20 Q. It would go up after the test?
21 A. Yes, well, it would -- I think the -- we were still 350
22 that we wanted on the surface, but to check that the grill
23 was in perfect working order, that the air flows were
24 working correctly, I believe that you had to do this test
25 to establish that. And that is why you have the
26 differences. What happens is that the flue at the back
27 draws the heat along the grill surface so that the back of
28 the grill would naturally be hotter.

30 MR. JUSTICE BELL: I think what is being put to you, when you
31 are doing those calibration tests, so you have got 325 to
32 340 at the front and so on, what is the dial actually
33 showing? Is it showing 350 which is the grill temperature
34 on page 545 for gas ---
35 A. I think -----
36
37 Q. -- the calibration as I understand it, is making sure that
38 your indication of temperature, weight, whatever it is, is
39 accurate?
40 A. That is correct.
41
42 Q. Speed, whatever it is?
43 A. That this is like a calibration of the flow of heat
44 across that particular grill surface.
45
46 Q. I understand that.
47 A. So, if it is set -----
48
49 Q. But, presumably, in relation to the dial, or whatever it
50 is, on the front of the machine which is telling you what
51 the temperature is, or is that a complete misunderstanding?
52 A. Although I cannot remember the procedures in detail,
53 I believe that you would have it set at 350 on the front,
54 and it was specifically after a length of time, after
55 switching that grill on, you would check and you precisely
56 had to do it at these positions at this time, before you
57 cooked any product on it, to work to know that you had the
58 grill, the gas setting set correctly.
59
60 Q. The assumption being that by the time you start cooking on
