I am currently trying to figure out how to operate this fireplace in the house we just moved into. The fan switch does not turn on the blowers, there are two of them near the floor. I am hoping that there is a thermal switch or a thermostat which is not allowing power to the blower system, and that there just isn't a short or other electrical issue with the blowers. I cannot find a model number on the unit, but while I was looking for this I noticed a metal rectangle on the floor which appears to open. I don't know if it opens, what's inside, or if this tells anyone anything about the unit. I looked for a thermostat wire or switch or sensor inside but cannot see one. Any help would be appreciated. Thanks.
