I have a Desa Vented Decorative Natural Gas Log fireplace.

Customer Question
I have a Desa...

I have a Desa Vented Decorative Natural Gas Log fireplace. When I ignite the pilot light it wont stay lit. Hold it in for 30 seconds but it keeps going out.

Contractor's Assistant: Just to clarify, what type of fireplace is this?

It was a log burning fireplace and was converted to natural gas

Contractor's Assistant: Do you plan on doing the work yourself?

Depends on whats wrong with it

Contractor's Assistant: Anything else we should know to help you best?

The pilot light did light a couple weeks ago and the flame stayed on, but since then it's gone out again

M​ost likely the problem is a weak thermocouple or pilot generator. If you hold the flame on longer, 3-5mins and then slowly release it, see if it will stay on then, if not then the thermocouple or generator needs replacing as it is too weak to keep the gas valve open.

Here is a link to a sample pilot generator as an example, it is the large round sensor, the thermocouple looks similar but is much thinner.
