Attic Insulation Shielding Overview:
Do you need the Attic Insulation Shield? One of these three methods should be followed (please see manual below for more details):
- If your attic space is greater than 15" in your flat ceiling installation, you should have room to install the attic insulation shield
- If your ceiling support protrudes 10" into the attic space, you can fit a storm collar around the chimney pipe and this would act as your attic insulation shield. (In this scenario you would be using the 24" ceiling support in the pitched ceiling kit and purchasing an additional storm collar)
- If the attic insulation shield will not fit (typically low attic installations), you are required to enclose the chimney pipe in a framed enclosure and maintain the required 2 inch air space to combustibles
- Please see manual below for more details
