Direct Vent Fireplaces

It is not recommended to burn wood in a Marco 792774B model fireplace, as it is likely a gas-burning fireplace. If you want to burn wood, you should look into purchasing a wood-burning fireplace insert that is designed for use with your existing fireplace.

'make model (what it is)' in all questions please.

It looks like it is a Febo Electric Fireplace. There is a recall on the 30A model and it gives the importer details, who should be able to supply parts.

Follow the pilot line from the gas valve this should show you where the pilot is .

This unit was made by Monessen Hearth Systems. The original heater/fan part has been discontinued; however, there is a new part that is compatible with your fireplace. You will need to search for part#10006404 Fan/Heater.

Hi do you the make and model

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.

go to ebay and put in electric fireplace heater parts, the flame motor is around 20 bucks, and the heater element around 50 bucks Good luck
