SS38 Direct Vent Gas Stove
1. Determine the route your vertical venting will take. If
ceiling joist, roof rafters or other framing will obstruct the
venting system, consider an offset. Figure 18 to avoid
cutting load bearing members.
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 shows in Figure 7 on page 12.
2. Set stove in desired location. Drop a plumb line down
from the ceiling to the position of the burner system exit
flue. Mark the center point where the vent will penetrate
the ceiling. Drill a small locating hole a this point.
Drop a plumb line from the inside of the roof to the locat-
ing hole in the ceiling. Mark the center point where the
vent will penetrate the roof. Drill a small locating hole
at this point.
