View Full Version : New use for re-formed 22 LR case

I've been working on a gas furnace in one of my apartments that had two problems: 1) pilot light kept going out 2) booming when furnace lights. The delayed-ignition boom was caused by corrosion in the burner orifices reducing gas flow and was solved by reaming out the orifices to the correct size. Since pilot light orifices also get clogged I took it apart to inspect it and discovered the orifice was missing completely. Apparently some past 'repairman' had taken it apart and lost the orifice. As luck would have it, a 22 LR case almost fits the pilot burner. I trimmed down the case, drilled a 0.040" (smallest drill I had, should be about 0.02") in the base, annealed the neck, and used my neck flaring tool to expand the neck to seal in the pilot burner. I now get a nice blue pilot flame that stays lit. Glad I saved a bunch of those 22 LR cases just in case I found a use for them.

That sounds pretty innovative. I spent many years as a furnace and AC repairman. You need to think outside the box quite often.

Is is this an LP or nat gas furnace?

natural gas, forced air, rated about 100,000 BTU/hr input.
