How to Inspect Your CoRayVac System


CoRayVac Annual Maintenance 

Money Talks

It is no secret that annual maintenance on HVAC equipment saves money in the long run. Operating your system at its optimum efficiency and detecting potential problems early can save you thousands of dollars over the life of your CoRayVac system.

Start-Up Suggestions


  1. Observe the vacuum pump discharge outside of the building to be sure that there is not a bird nest or any other obstruction. A bird screen should cover the end of the pipe.
  2. Be sure that the flexible boot connectors at the vacuum pump are in good condition.
  3. Inspect tubes and reflectors. If any reflectors have shifted and are laying directly on a tube, a hotspot is created and can damage the tube.
  4. Check the vacuum on your system. (-2.0 to -3.0" W.C)
    1. Replace filters annually with genuine Co-Ray-Vac filters.
    2. Filters must be clean (white) to accurately measure the vacuum.
  5. Test fire your heater by raising the thermostat set point before the start of the heating season .
