Raypak Heater Pilot Catching Fire

[albel1214]

Hi Everyone I have a Raypak heater. I tried to kick it on and received an ILO message a couple times. Finally I heard it light however I saw a flame at the bottom of the unit. I pulled off the cover and noticed a large oragne flame around the pilot assembly. I quickly turned off the heater.

Does anyone have an idea what would cause this?

Could be a clogged pilot light, flame should be blueish. Try cleaning it with compressed air, toothbrush, or a vacuum. Double check everywhere for signs of mice moving in.

Here is a picture of what I see when it kicks on... Thoughts?

As was suggested in your other thread, remove the gas valve and blow it out if cleaning while in place does not do the job. If you take it apart use a mixture of dish soap and water to look for leaks prior to lighting the furnace. You may need pipe compound to seal the threads.

I did unscrew and blow compressed air into the pipe at 1. Same issue. Any way to remove this pipe completely at end 2?

There should be a bracket attached to the pilot assembly with screws so you can remove all the pilot tubing and assembly then you should check for any loose fittings on and around the end. Also wire brush it to clean it up there is also an orfice inside the pilot assembly make sure that is cleaned out too using a small wire strand should fit in it
