Answers
Which natural gas piping is not permitted in any jurisdiction? Aluminum
For complete combustion and ignoring dilution air requirements, natural gas requires
approximately 10/1 volume ratio of gas/air
Natural gas is Lighter than air
A common temperature rise across a conventional furnace is 70 F - 100 F
You turn up the thermostat and the induced draft fan fails to start. This is most likely to be a
problem with the Heat exchanger
The most common gas piping is Black steel
The flame of the left burner in a two burner conventional efficiency furnace touches the heat
exchanger only when the blower is running. Why The heat exchanger is cracked on the left
side
