1. Install the gas filter correctly

This is where most problems start.

• Check flow direction → there’s always an arrow on the filter body. Match it with gas flow.

• Install before key components
  Usually:
  Gas source → filter → regulator → solenoid valve → burner

• Keep it accessible
  Don’t bury it. You’ll need to clean it regularly.

• Vertical mounting preferred
  Bowl facing downward helps trap dirt and condensate.

2. Before starting the system

Always do this before opening gas:

• Make sure the filter bowl is clean and properly sealed

• Confirm the O-ring / gasket is intact

• Slowly open the upstream shut-off valve to avoid a pressure shock

• Check for leaks (soap solution or gas detector)

3. During operation

While the system is running:

• Watch the pressure drop across the filter

  • Sudden drop = clogged element

• Listen for abnormal noise (whistling = blockage)

• Ensure stable flame at the burner
  (dirty filters cause unstable combustion)

4. Cleaning & maintenance (very important)

How often depends on gas quality, but monthly inspection is common.

Cleaning steps:

1. Shut off gas supply

2. Release residual pressure safely

3. Remove the filter bowl

4. Take out the filter element (mesh or cartridge)

5. Clean with:

   • Compressed air (blow from inside → outside)

   • Or mild solvent (if manufacturer allows)

6. Dry completely

7. Reinstall and tighten properly

⚠️ If the element is damaged or heavily corroded → replace it, don’t reuse.

5. Common mistakes to avoid

These kill filters fast:

• Installing backwards

• Never cleaning until the burner fails

• Using the wrong filter rating (mesh too fine or too coarse)

• Ignoring condensate or oil buildup

• Overtightening the bowl (cracks it)

6. When to replace the filter

Replace immediately if you see:

• Torn or deformed mesh

• Heavy rust or scale

• Repeated clogging in short time

• Gas pressure can’t recover after cleaning

Pro tip (from field experience 😉)

If your solenoid valves or regulators keep failing early, 90% of the time the gas filter is undersized or poorly maintained.
