typed the following:

My unvented indoor gas fireplace consistently lights up just fine for a
few minutes, then pops off for no apparent reason.
Does this sound like it's a safety device that wrongly thinks the flame
went out? Is this something an average homeowner should attempt to fix?


There is a temperature sensor inside the unit. It is a small silver
colored cylinder with a woven metal wire attached that clips onto the
firebox somewhere. It may be mounted too close to the heater unit. Move
it further away and/or lower.
That could be a simple reason, but there could be another more technical
one. Start there and see if it helps.
