Re: Repairing wall mounted gas heater.

Hey Abrasha,

Somebody mentioned using Teflon tape on the threads of the fitting,
and somebody else said it's not the threads that are leaking, and that
the Teflon won't stand up to the heat.

Teflon isn't only to "seal" the threads, but to make them "slippery"
so that you can tighten the fitting better/tighter, which would
probably help in your case. And here in Canada, we have to use the
"yellow" packaged Teflon tape that is approved for use in gas
applications. Ask at the hardware store.

Take care.
