Inquiry (采购产品): Markel Model G1G5103N In 1997 I bought two of these heaters from a Venture store that closed in Houston. I would like to install them into a work shop I now have. I was wondering if I could get a wiring instructions for these heaters. I will be glad to pay for the mailing and any charge for the instructions. Also can they be wired to come on just from a switch, or do they have to have a therostat?
