Question

A non-technically exhaustive way to evaluate the heat exchanger?

a. Remove plenum and inspect visually
b. Water pressure test
c. Check flame pattern when blower comes on
d. Inspect register covers for soot

Answer 1

To evaluate a heat exchanger non-technically, you can visually inspect it, perform a water pressure test, check the flame pattern, or look for soot on register covers. These methods are practical and don't require advanced technical tools.Option A is the correct answer.

Step-by-step explanation:

The question "A non-technically exhaustive way to evaluate the heat exchanger?" relates to practical methods for inspecting and assessing the condition of a heat exchanger without employing specialized technical equipment or procedures. Let's go through the options provided:

1. Visual inspection of a heat exchanger typically involves removing the plenum to physically look at the components, checking for any obvious damage or blockage.
2. A water pressure test can identify leaks within the heat exchanger where water is forced through the system under pressure.
3. Observing the flame pattern when the blower comes on can indicate whether the heat exchanger is operating correctly. An irregular flame could suggest a problem.
4. Last, inspecting register covers for soot can be indicative of incomplete combustion and potential issues with the heat exchanger's performance.

These methods do not require sophisticated technical equipment but can provide valuable information about the state of the heat exchanger.
