I have a new dicovery to ask about? I have used my fireplace in the montie for a few hours now that its getting cooler. I have the 3485SA. I noticed that the board above it is very hot, has anyone noticed a scorching or burning of that board? I remmember the problem above the light bar in the bathroom. I got a piece of 18Ga. sheet metal and painted it with high heat paint, them used alum. spacers 1/6" and molly screws to the ceiling, That keeps the heat off the roof, so no dicoloration. I may have to do the same above the fireplace. any suggestion would be welcome. Thanks Randye
