we have a ventless gas fireplace with a thermostat. on occasion, fireplace will automatically start up (dangerous). we want to replace thermostat with on/off switch. is that possible? is it a special switch (heat resistant)?
If the thermostat is mounted on a wall, why not replace it with something like a Honeywell 1000 heat only thermostat? It has a built in on-off function and sometimes a regular wall type switch tends to create a great deal of resistance causing a "no heat" situation (will not light) if the fireplace only uses a millivolt type circuit.

Thanks for the reply.
no, my problem is that there is a thermostat (w/thermocouple) attached to the fireplace gas unit and a dial is the adjustment for the temp setting. i want to remove this switch and replace it with an on/off switch so it doesn't come on automatically.
is this dial on the gas valve? If so you are talking about a snap action hydraulic gas valve. If this is the case. You would need to replace not only the gas valve, but potentially the pilot assembly, add a thermopile and then wire in a wall switch.
I may be off and not understanding, but from the sounds of it, this would be necessary if your gas valve has the dial on it.
dial is on the gas valve.
my last home had gas fireplace w/pilot lite. when we wanted flames, we turned up the valve and it ignited just like a stove would.
thats what i'd like to get back to, instead of a fireplace that acts more like a furnace and automatically comes on when the temp drops. i was trying to get by, by hopefully just replacing the thermostat with an on/off switch instead of a new log set.
you are going to have a lot of time and money wrapped up in this..... also not to mention a dangerous situation if you are unfamiliar with working with gas appliances. It can be done, but I don't recommend by a DIY person. Best to get a pro involved, but by the time you do that, you may be getting into putting a different log set in.......
always looking for a less expensive alternative, but also know that sometimes its better to take the high road. guess i'll be ordering a new log set.
thanks for all your help
sounds like you have a thermostat controlled set of logs. Like he said. You will have a set with pilot generator to operate off a light switch. Would cost too much to convert
