I need a millivolt gas valve for a 18 inch propane ventless log set . Could you tell me what parts I need for this conversion. My gas log set has a maxitrol variable valve on it now. I want to be able to control my log set by a thermostat remote.

Answer:While we have many gas valves and components for vented application, you will be limited to the original type of valve that came with the vent free set.
Due to the multitude of safety guidelines for vent free sets, aftermarket valves are not currently available. It will be necessary to consult with the manufacturer of the log set to see if the valve can be retrofitted for use with a thermostatic remote.

I bought a used Malm Fireplace that came with a Euro SIT 0630516 valve. This valve has been superseded by their SIT 0630958.
I am trying to avoid buying a replacement SIT valve since there may be a problem with the pilot assembly as well. Malm tells me the the Dexen 6003 is what they install on their new fireplaces.
Q1. Is this Dexen 6003 compatible with the SIT 0630516?
Q2. Does it include the pilot and piezo assembly?
Q3. How difficult would it be to mount it to the Malm Fireplace (CArmel model) ??
Q4. If I install this Dexen 6003 could anything else require replacement??

Answer:This valve is indeed a complete assembly and will come with the thermopile and piezo ignitor. This should be everything that is needed to retrofit the existing valve in your fireplace.
I am currently checking the BTU capacity of the old SIT 0630516 to ensure that this is comparable to the Dexen valve. If they are similar to one another, there should not be a reason the valve could not be retrofitted to your unit.
As far as installation difficulty goes, I cannot speak to this point, as we are not a dealer of Malm fireplaces and I have little experience with how they route the thermopile/pilot leads. Depending on how far away the valve and pilot are located, longer leads may be necessary.
I have verified the the Dexen and SIT valves are indeed within 2K BTUs of each other and have similar incoming gas pressure requirements. As I mentioned, a retrofit should be able to be done.
However, I would still contact Malm to discuss the possibility of the swap, as they will have more information on what will need to be done.
