Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shown in
Figures 24 and 25
.
2. Set fireplace in desired location. Drop a line plumb down
from the ceiling to the position of the flue exit. Mark the
