Flush Wall Finish Detail
MAGNUM replaces are designed to be installed so that the rough front face of the rebox and damper beam project into the room
approximately one-half inch (1/2”) beyond the face of the rough framing members that create the room’s wall surface.
The MAGNUM smoke dome front sits two and three-fourths inches (2-3/4”) back from the rough face of the rebox and damper
beam. This set back dimension allows for one and one-half inch (1-1/2”) framing plus one-half inch (1/2”) thick wall board to pass
in front of the smoke dome and at the same time align ush with the room face of the MAGNUM damper beam. Set in this position,
framing and wall board are kept to the required eight inches (8”) above the rebox opening top (Figure 25).
Important: Do not build a frame wall in front of the MAGNUM rebox and damper beam. (Figure 26)
