Recently, I was approached by a key member of this group with the intent of bringing us all together as a consulting team to tackle the task of addressing the energy consumption and conservation needs of light commercial buildings (less than 100,000-sq.ft).

This month I want to address the natural gas fired, forced draft appliance, most of which have a finned tube heat exchanger of one design or another.

In last months article, we ended by telling you we would look at the tales of the tape from combustion analyzer readings to analyze the analysis, and make a determination as to corrective actions. I realize that the title of the article is relating to the newer gas fired high-efficiency equipment, but the reality of the matter is that there are more atmospheric appliances out there than there are high-efficiency appliances, and a person needs to understand the basics of combustion before they can move into the high-efficiency arena.

Are you properly commissioning your new gas fired high-efficiency equipment? If you are not, you just might be voiding any warranty on the consumers' equipment...

Editor's note: This is the third and final in a series of articles addressing means manners, methods and tools that will increase employee speed and efficiency in the field.
