I have a Vermont Castings vented gas fireplace heater model SDV30RF. It's made for propane but I got a conversion kit when I bought it so it now runs on gas. It's amazing. It heats up my small 535-square feet condo really well. And it's very efficient. My question is this: So far I use the remote control to operate it. The remote is really easy to use. But if I did not have the remote, could I still operate this heater? Also, does anyone know the number I can call for tech support for this product?
