Before you start
Use the equipment manual and model-specific instructions as the primary source. Shut off power, water or fuel only when the manufacturer procedure calls for it and you are comfortable identifying the correct control. Stop if the condition you find is different from what the guide describes.
When to bring in a professional
This task includes work that may require specialized tools, safe access, combustion/electrical knowledge or a qualified inspection. Use the steps above as the homeowner checklist and preparation guide, then hire the appropriate professional for the higher-risk portion.
