You need to find out the manufacturer of your gas log/burner set and replace any parts needed with those designed for your particular unit. Most manufacturers make remote controllers for their fireplaces.

Thanks for replying. The thermocouple stopped working anyway so I have to replace the whole gas burner system anyway. So I believe I need to find a complete set with burner and remote. My fireplace is Superior BR-36-2 - https://www.allpartsinc.com/superior...e-br-36-2.html

Vented vs. Ventless Gas Fireplaces.

https://www.heatair.org/

In a traditional vented gas fireplace, there are two vents that run to the outside of the home. One is a fresh-air intake that provides combustion air help the gas burn more efficiently. The other vent safely removes any exhaust gases created by burning the natural gas or LP to the outdoors.

On the surface, a ventless gas fireplace looks quite similar to a vented fireplace. It has a control panel to operate the pilot light and flames, and holes in ceramic artificial logs for the flame jets. There is a slight difference to the flame jets between the two styles, and as a result, ventless fireplaces tend to burn somewhat less realistically than vented units. As with vented fireplace, ventless units usually have blowers that circulate air around the firebox to heat the room.

However, ventless fireplaces have neither of the two outdoor vents found in vented units. Instead, combustion air for the burner is drawn into the fireplace from the air inside the home, and exhaust fumes also remain inside the home.

This may sound dangerous, but ventless fireplaces are engineered in a manner that minimizes the exhaust fumes. A special regulator creates a fine mixture of gas and air that burns extremely cleanly, and the units are carefully tested in approved laboratories before they can be sold. Ventless gas fireplaces are deemed to operate within the range of safety for cycling these combusted gases back into the home's interior. By contrast, vented gas fireplaces create a dangerously high amount of combustion exhaust and therefore must be vented to the outdoors.

Based on the model number you provided, you do not have a vented gas fireplace, You have a wood-burning fireplace and have installed gas logs. However, since it already has the gas supply pipe, there are many different places to buy a new set of gas logs.

I have used Hansen Wholesale in the past, and purchased Peterson Real Fyre gas logs. One set was like the ones you already have (manual lighting), and the other set had a remote. I don't think you can mix and match controls and have any assurance it will work correctly, so I would plan to buy a complete new set of gas logs.

Questions to Consider When Choosing a Gas Fireplace

Is a Vented or Ventless Gas Fireplace Better?

A gas fireplace doesn’t produce smoke or odors, but its flames do create pollutants, such as carbon monoxide and nitrogen and sulfur oxides. Vented fireplaces send these emissions outside, while ventless ones direct them into your living quarters.

Wood-burning fireplaces provide great ambience, but they can't beat the easy, no-fuss efficiency of gas.

You don't have to split, stack, season, or haul logs.

There are no ashes to bag, no smoky smells, no chimney to clean.

You can start, adjust, and snuff out fires with the touch of a remote control.

The fire needs no tending and won't die out from neglect.

A wall thermostat can control the flame size—and therefore heat output—to maintain a specific temperature setting in the room.

The fixed glass panels covering direct-vent fireboxes ensure that the furnace- or boiler-heated air in the rest of the house doesn't escape up the flue, as it does with a wood fire.

You can get as much as 75 to 99 percent of a fuel's energy back as heat, instead of the 10 to 30 percent for wood fires.

Gas fireplaces can go almost anywhere—in an upstairs bathroom, in a basement, or outdoors—without needing a chimney.

Questions to Consider When Choosing a Gas Fireplace

How much does a gas fireplace cost?

Expect to pay $2,000 to $5,000 (including installation) for a heat-producing insert or built-in fireplace. Decorative log sets run about $400 to $1,000.

Should you use natural gas or propane?

Gas fireplaces can burn either type. Natural gas is less expensive and produces about 5 percent more heat. Choose propane where natural gas isn’t available.

How much care and maintenance?

For about $150, have your certified technician come once a year to clean and adjust the burner, ensuring that you have realistic, soot-free flames.
