Where are the gas pressure, draft readings?

摘要

Winnipeg, manitoba - Not to be critical of Mark Eatherton's work as I have been reading it with enjoyment and sharing his articles with my staff, students and industry colleagues for a long time. But in the early stages of the multi-part series on combustion, (Properly commissioning gas-fired high-efficiency equipment, May to September 2011) he always talked about and stated the gas pressure readings, draft, temperatures and now, for whatever reason, he has dropped the gas pressure readings and draft readings, especially in Part 5 (September 2011, p. 46, or at http://bit.lyFRaS3). The omission of all the information is typically why so many contractors and technicians fail to fully grasp the whole combustion testing. ;CUSTOM@CUSTOMVAC.MB.CA;
