6.3 Wavin fire protection concept
Wavin Fire Protection Collar is in practice the best available
solution. The Wavin Fire Protection Collar BM-R90 fully seal
the wall or ceiling corridor in case of fire, due to special fire
protection material which strongly expands by increased
temperature.
The BM-R90 Fire Protection Collar (for Wavin AS+) is especi-
ally for sloped piping, suitable up to 45 degrees, and applica-
ble for passages by sleeved pipes or fittings. In practice the
collar is suitable to seal off almost any possible configuration.

6.4 Assembly instructions
When the system is applied to a fire-resistant vertical (wall)
or horizontal installation (floor) which separated a fire-risk
area, only one Fire Protection collar is required. If the system
is applied to a fire resistant vertical (wall) or horizontal (floor)
installation which separated two fire-risk areas, use a Fire
Protection collar on both sides.
Hole
Drill a circular hole into the wall or floor with a diameter of
2 mm greater than the external diameter of the plastic pipe
to be used.
Installing the pipe
Insert the PVC, PP, PE etc. pipe in the hole and clean the part
the collar is to be applied to.
