Most fire place burners have an oxygen depletion sensor on them nowadays. If you can restart it after a while, a few minutes or so, and shuts off, it is probably the oxygen sensor. The owner lights fireplace and shuts the door, and the fire depletes the available oxygen and the fire will start producing copious amounts of CO which is a hazard. Most fireplaces have a fresh air supply available to provide combustion air but needs to be opened for the fireplace to work properly. Check the manufactures recommendation as to the proper installation of the fireplace furnace.
Hope this helps

with high temp refractory mortar for fireplaces

You will need to cut back the mortar from the front so you can install the fan kit. If you want to try and do it yourself you will need a masonry blade (diamond blade) on a skill saw and set your thickness on your skill saw to very thin so you don't cut into the fireplace.
Other option is to get a chisel, depending on how much overlaps onto the face, and chip it all back.
You are correct that if you do not get the mortar off of the front to where you can open the front you will not be able to install the fan kit. You can pull up this installation manual at this website http://vermontcastings.com/family/Fireplaces/Wood-Burning/Sequoia/
Good luck. Vermont Castings

If your blower/fan blows air into a "box" with tubes that conduct heated air out through the screen, that assembly may have failed. I had one that burned out and had to be replaced.

To regulate air flow, there are damper devices built into the stove, flue and stove pipes. Keeping the air flowing correctly through a wood-burning stove is essential for safe and efficient operation of the stove. Fresh air needs to enter the wood compartment to provide oxygen fuel for the fire; as the fire burns, the smoke must be allowed to rise through the stove pipes, and exit through the chimney.

Unfortunately, you didn't list the model number of your fireplace and whether it's vented or vent-free. However, I suspect it's vented, as MARCO (now out of business) manufactured very few vent-free models. Restoration is going to depend on the condition of the burners, as well as the gas control valve and the condition of the firebox. The small ports you mentioned, are for the Rock Wool (Glowing Embers), which are divided into small pieces (dime size) and fluffed, then placed over the small ports. MARCO did not make a vented fireplace where silica sand was used on top of the burners. Normally, you only see that on vented gas log set, that is installed in a solid fuel burning (masonry) fireplace and operated with the damper fully open.

As far as restoration parts are concerned, I seriously doubt there are any available. MARCO, as such, has been out of business for almost 10 years. Today's burners are not designed for the same configuration that you have. It wouldn't be wise to try to change the configuration, as the firebox was tested and approved for only what's in there now.

Wish I had better news for you. But, my 15 years in the hearth and home business, tells me it would difficult and costly to do.

The fan should be installed behind the bottom grill, and then it should blow air around the firebox which then exits out the top grill. Now saying that, let me explain the actual problem you will face. Because you have a open faced wood fireplace, you will not get the heat your looking for, the fire needs 400 cubic feet of air per hour and that air is taken from your opening. Also the inner box doesn't heat up enuff to produce alot of heat on the skin so if you have the fan blowing full blast, it will only cycle the air and not allow it time to heat up as it cycles around the box. I suggest turning the fan speed down so its 1/2 way on or lower, this allows the air time to heat while cycling around the box, but in the end you still won't have a good heater as the fireplace itself isn't one, you should look at having it converted to direct vent gas or ripping it out and replacing it with a airtight wood.

I would use industrial Fire Chalking. You can gat it at most home repair centers.
