I recently bought a house with a marco natural gas fireplace. The unit will lite but after about 30 min will shut down and you can smell gas. Where can I pick up a manual and what could cause this problem? thanks
This an easy fix. What you must do is remove the dust from the pilot safety. I use rust buster from ace hardware to gently flush the hole. If ther is no hole just shoot a tiny drop or 2 into the pilot burner where the flame comes out. Blow it out (I use a piece of tubing). The problem is the dust drops the pilot flame to a point where it won't heat the thermocouple hot enough to jold the magnet and after 30 minutes she quits. THIS is a picture of where to clean the ODS pilots in your rig.

I have the same problem! A friend says that it should shut off when it gets hot. There's a sensor that will turn the fireplace on and off.
Does anyone know if this is accurate?
My fireplace runs for 10-30 minutes then shuts off by itself.
The pilot goes out as well.
I have to re-light the pilot and start the fireplace again, and then the same thing happens.
