Gas Fireplace Service Checklist

Recently, Bardi Heating, Cooling & Plumbing announced the exciting addition of gas fireplace installations to our services. We all know how important it is to have our heating and cooling systems checked and tuned up each year, but did you know it’s equally important to have your gas fireplaces tuned up? Regular inspections are necessary to ensure fireplace safety, and neglecting to do so could allow a gas leak or other safety risks to go undetected. We use this detailed safety inspection checklist for our customers’ vented, vent free, direct vent and b-vent fireplaces:


  1. Check fireplace and all venting for proper clearances, connections, and configuration if accessible.
  2. Check and clean top of unit for any debris or construction materials, if possible.
  3. Check termination cap condition and location:
  4. On horizontal caps: Check for distance to soffits, mechanical and non-mechanical air inlet, doors, service regulator vent, deck, porch, inside and outside corners, other horizontal gas fireplace caps, or other conditions that could affect operation of the fireplace.
  5. On vertical caps: Check for spacing to other termination caps, perpendicular walls, height above roof line, walls, and other obstruction or conditions that could affect operation of fireplace.
  6. Check mantel and surround legs for clearance per installation instructions.
  7. Ensure that circulating features are not covered up and that front face is not covered by combustibles.
  8. Ensure proper set-up of lava rock, vermiculites, and glowing ember bed. (Only glowing embers should be placed on burner pan, or in flow of gas, and air slots around burner must not be blocked.)
  9. Check all wiring connections for tightness, and proper wiring per schematic in installs.
  10. Check all accessible gas connections and components for gas leaks.
  11. Remove and clean glass on Direct Vent Models.
  12. Remove logs and clean each log.
  13. Remove burner and burner pan and clean.  Making sure burner venturi is clear and burner orifice is also clear.
  14. Check igniter gap to pilot hood. Use a gauge or measure (1/8”).
  15. Check that pilot sensor rod or thermocouple is clean.
  16. Check for strong spark that arcs to pilot hood in gas flow on every tick of spark cycle.
  17. Check that pilot flame is located in gas flow from main burner, and that main burner light immediately after pilot.
  18. Check that spark stops within 15 seconds after main burner has lit if applicable.
  19. Turn unit off and check that pilot goes off too. (Unless it has been wired to stay on).
  20. Check pilot flame alignment with thermocouple/thermopile. (Flame should engulf tip and should glow red soon after lightning.)
  21. Cycle unit on/off.  Let unit run for 15 min making sure combustion is occurring correctly.
  22. Check Thermopile in VDC to measure strength of thermopile from TH to TPTH terminals on valve.
  23. Check gas input pressure while unit burns. Natural Gas: 4.5 – 7” WC; Propane Gas (LP): 11 – 14” WC (Write actual reading on line.)
  24. Check gas output pressure while unit burns. Natural Gas: 3.5” WC; Propane Gas (LP): 10” WC (Write actual reading on line.)
  25. Test all options (fans, remotes, glass doors etc.) for proper operation.
  26. Clean on top of and under firebox of any debris or construction material.
  27. Clean and inspect glass, ensure proper placement, and seal onto unit; ensure latches in place, if applicable.
  28. Replace burner and logs to factory specs, add ember to burner if applicable.
  29. Using CO detector checking to see if glass sealed securely.
  30. Ensure safety screen in place properly over glass, if applicable.
  31. Check for all other parts present and properly in place.
  32. Clean area around fireplace.
