I just purchased a home which has a Martin SC36 fireplace, or at least that is what it says. I was not told this existed and was going to purchase a gas fireplace, so this is a nice surprise. However, there is no manual and I have zero knowledge of gas, let alone gas fireplaces, so any info you can send me would be greatly appreciated. The other number on this is 018181 with a date of 031191 by Martin Industries. Thank you so very much
