Clearance to Combustibles and Framing Requirements
Table 1 shows the required MINIMUM AIRSPACE CLEARANCE TO COMBUSTIBLES. EZ Seal/EZ 316 - 6"-16"
and model GC/GC 316 are primarily intended for installation in fire resistive, non-combustible surroundings or
installed unenclosed. This airspace clearance is required for safe operation of the vent. Failure to follow these
clearances could overheat the building materials and could cause fire.

Vertical (Floor, Ceiling and Roof) Penetrations
All vertical penetrations where the vent passes through a combustible floor, ceiling or roof, require a Fire Stop (p/n
5x18CI) or Roof Jack be installed. See Table 1 for proper framing dimension and refer to the Fire Stop or Roof
Jack Section for proper installation. Non-combustible Floor, Ceiling & Roof Penetrations do not require a Fire
Stop or Roof Jack.
Horizontal (Wall) Penetrations
Horizontal systems passing through a combustible wall require the use of a Wall Penetration, for relative
temperatures with clearances. See Table 1 for proper framing dimensions and refer to Wall Penetration section
for installation instructions. Non-combustible wall penetrations do not require a Wall Penetration.
See Table 1.

In addition to the configurations shown in Figs. 1 & 2, this system may be installed in any combination of vertical
and horizontal, unenclosed configurations as long as the minimum clearances are maintained per clearance
Table 1 and the total length and number of fittings does not exceed the appliance manufacturers
recommendations. This system may also be installed within an existing masonry chimney.
