its no secret that i realy dont understand fga readings, yes i know the action levels and i can compare what ive got to the manufacturers recomendations
but im seeing condensing vaillants that chuff out 180 ppm co and old turbomax non condensers in the 30/50 ppm i thought the new ones were supposed to be better
