How to Inspect the Fuel Supply and Shut-Off at the Heating System

When the inspector is at the heating system the inspector should check all exposed gas piping for any gas leaks. The gas detector should be turned on as soon as you start to inspect the system because it will take a few moments for it to calibrate before it is ready to test for any gas leaks. Please review the entire procedure below.

NACHI SOP

International Standards of Practice for Performing a General Home Inspection

 

3.6. Plumbing

 

I. The inspector shall inspect:

N/A

 

II. The inspector shall describe:
D. The location of any observed fuel-storage system.

 

III. The inspector shall report as in need of correction:

N/A

 

IV. The inspector is not required to:

A. Light or ignite pilot flames.

H. Operate any valve.
S. Test, operate, open or close: safety controls, manual stop valves, temperature/pressure-relief valves, control valves, or check valves. V. Inspect or test for gas or fuel leaks, or indications thereof.

 

Axium SOP Differences

Axium Requires: The inspector will check the gas piping at the heating system for any gas leaks. It is also important to check the piping and the burners inside the furnace.

 

Tools Needed

The inspector will use the gas detector to check for any gas leaks.

 

Procedure

  • While inspecting the heating system you will need to get out your gas detector and turn it on. Do this at the beginning when you first start to inspect the heating system because it will take a minute for it to calibrate.
  • Once the gas detector is calibrated you will slowly start to run it along the gas piping of the heating system checking for any gas leaks. If there is a leak it will begin to beep very rapidly. We also want to check inside the heating system where the burners are located for any gas leaks.
  • If there are no leaks present you will take one picture with the gas detector in your hand showing that you tested the gas piping. You also want to make sure that the shut-off valve is in this picture.

Common Defects

  • The heating system is missing a gas shut-off valve.
  • There is a gas leak at the heating system

Common Mistakes

  • Not checking for the presence of a shut-off valve.
  • Not checking all of the piping for gas leaks.
  • Not taking a good picture with the gas detector in hand showing the shut-off valve.
