how do you clean a standing pilot?
The other day, I came across a blocked pilot orifice on a 20 yr old gas boiler.I unscrewed the pilot tubing, held up the bracket and tried to blow through it. Nothing would go through. Got a hold of a sewing needle and carefully ( not do damage the orifice) scraped rust off the orifice from the back side. I was all happy with myself as it worked. Later that day, I read in some literature a Warning- Never clean pilot with needle because can damage the ruby orifice and will mess up the metered amount of gas that goes through it. Is this accurate? Are you supposed to replace the pilot bracket assembly if can't blow through it? Wouldn't I see if I damaged it (when I used needle) by observing the pilot for a few minutes and seeing it burn steady and calm?
