| 1158 S/W. Rm{William Robotham - Chief Engineer}/Std. Copy to Hr. Re Clayton Heaters. With reference to our conversation with you yesterday regarding the installation of the Clayton Heater, we note you consider it is not worth while going to the expense of fitting drain taps to the flow and return pipes of the Clayton Heater. We shall, in future, discontinue this practice and if you consider there is any risk of damage by frost, perhaps you would like to arrange for a note to be put in the Instruction Book. Also we note you would like to eliminate the copper piping as much as possible and we are looking into this and no doubt can considerably reduce the amount of piping used hithertofore. W.L.H. | ||
