First, turn the wall switch to the off position. Second, turn the key all the way tcountercockwise to the open position. At the front of the unit, below the hearth opening there is a black front access panel. Should have a little recessed part. pull it out and expose the gas valve. Turn the plunger/knob that says off, on, pilot to the pilot position. You'll knw your in the pilot position when it lines up with the indicator (usually a red or black mark on the gas valve body). If you are in the pilot position, you will be able to push in the pilot (it will feel springy). Push the plunger in and then push the red button (piezo ignition button) in until it makes a snapping sound. You may have to do this several times because the air has to bleed out from the pilot tubing. This should light the pilot BUT wait. DO NOT LET GO OF THE PLUNGER ONCE THE PILOT IS LIT. You need to keep the plunger depressed for about 30 seconds and then let it go. After 30 seconds let the plunger go and verify the pilot is lit. If not try the last step over. After the pilot is lit, you may turn the plunger/knob to the on position. Now go back to the wall switch and flip it on. If it doesn't come on tap it hard. Sometimes dust can actually prevent it from making good connection. I work on fireplaces for a living and coincidentally worked on this model today. Simple as pie.

I have a marco 36" standing pilot natural gas fireplace. Model is either 794015C or 794019C. It has bi fold doors. I don't know if i need to have doors open or closed during operation, or if it matters...


Small lava rock on bottom (can be bought where you buy gas grills, fireplaces and their parts. The embers at a fireplace shop. Doors open when using and closed when not. If doors are closed while fireplace is being used, they get extremely hot and may burn someone not expecting them to be hot.

My fireplace lights but shuts down within a minute and pilot goes out. Pilot will relight but Fireplace will not relight for a while. Keeps doing this, will sometimes stay on. Does this describe enoug


Sounds like a sensor problem or a gas blockage. Get a gas expert to look at it. Gas is dangerous and can cause severe burns or explosions resulting in loss of life and property.

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.
