Before you begin
You will need:
- Recommended PPE: Safety glasses and cut-proof gloves
- Drill with 1/8” and 3/16” drill bits, and a 10 mm hex bit for driving screws
- Hammer and a center punch, nail set, or a large nail to make a dent in the pipe to prevent your drill bit from wandering
- Angle grinder with metal cutoff blade or hack saw for cutting shields to size
- File/sandpaper for smoothing freshly cut edges
Step 1: Plan your heat shield layout
When installed with the included 1" standoffs between the stove pipe and the heat shield, this shield design meets the NFPA-211 specifications for an air-cooled heat shield to reduce wall clearances by up to ⅔ (from 18” down to 6”) measured at a 90-degree angle to the pipe. If a horizontal or angled pipe comes within 18” of the ceiling, the pipe mounted heat shields can be used to reduce ceiling clearances by ½ (from 18” down to 9”).
Because of the upward convection current created by a vertical pipe-mounted heat shield, we recommend converting to insulated pipe no less than 10 inches away from the ceiling when using this product in a vertical orientation.
Orient your shield so that it covers all parts of your pipe that have less than 18” clearance to combustibles (measured at a 90 degree angle to the pipe).
Leave 1” of space at the top and bottom of the shield to allow adequate airflow for the shield to function properly.
Most installations will require heat shields to be cut and/or overlapped with a second shield. Use an angle grinder (preferred) or hack saw to cut a shield down to size, and a file or sandpaper to smooth the sharp newly cut edge. Use the holes of the cut end as a pattern to drill new holes in the freshly cut end. For installations requiring multiple sections of heat shields, overlap the shields by lining up the mounting holes at each end.
Step 2: Mount Shields
Orient your shield so that it covers all parts of your pipe that have less than 18” clearance to combustibles (measured at a 90 degree angle to the pipe).
Leave 1” of space at the top and bottom of the shield to allow adequate airflow for the shield to function properly.
Most installations will require heat shields to be cut and/or overlapped with a second shield. Use an angle grinder (preferred) or hack saw to cut a shield down to size, and a file or sandpaper to smooth the sharp newly cut edge. Use the holes of the cut end as a pattern to drill new holes in the freshly cut end. For installations requiring multiple sections of heat shields, overlap the shields by lining up the mounting holes at each end.
Step 3: Check your installation
Before using your stove, double-check to ensure that the heat shields are providing adequate coverage, and your clearances are sufficient.
