Dan Webster's pilot fix worked. Pilot now is blue and stays lit. Main burner still does not fire, so next step is new thermocouple.

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 a Model 792864B. Before you attempt to light the pilot light - make sure that any wall control switch or remote control for the fireplace is in the off position. Locate the gas supply line. There should be a gas supply valve to turn on the gas supply. The valve is usually painted a different color than the supply line like blue, green or yellow. Open the valve by pivoting the handle to be parallel to the gas line, usually counter-clockwise. When it is closed it is at a 90 degree angle from the supply line. Locate the pilot light assembly - this is the pilot light. There should also be a red or black ignitor button and a black or green valve control knob with the words "on" "off" and "pilot" on it. It may be located inside a black box, mine is marked heatolator, that has a lift off top. Lift off the top of the box. Push in the valve control knob and turn it until the word "pilot" is in line with the arrow (my arrow is red) or indicator line. While pressing and holding in the valve control knob - it presses in about 1/4", press the red or black ignitor button repeatedly (once per second) until the pilot ignites. Once the pilot is lit, continue to hold the valve knob in for about 30 seconds and then slowly release. The pilot should remain lit. If it remains lit, press in and turn the valve control knob to the "on" position. The on/off wall or remote control switch should now light your fireplace. If the pilot doesn't ignite, turn off gas supply valve, wait about 5 minutes and try it again.

Our fireplace is a Marco Gas fireplace. It has special logs that are placed on a grate. I've been told that I cannot use any other type but what was made for this fireplace. I need to know where I can purchase them. The manual gives me a replacement parts list. what I need is the grate, cross log, back log and front log. Everything else works fine.
I'm not sure what else I can tell you. I'm looking for the grate and log set for the above mentioned fireplace. there must be a supplier that can replace the above mentioned items. If the the business is out of business they they sell the parts to another compan? What else do you need to know. I have given you the information from the manual for Marco Gas Fireplace.
