C. Ceiling Firestop/Floor Penetration Framing
A ceiling firestop MUST be used between floors and attics.
• SLP Pipe - Frame opening 9 in. x 9 in. (229 mm x 229 mm)
whenever the vent penetrates a ceiling/floor (see Figure
5.3).
• Frame the area with the same sized lumber as used in
ceiling/floor joist.
• The ceiling firestop may be installed above or below the
ceiling joists when installed with an attic insulation shield. It
must be under joists between floors that are not insulated.
Refer to Figure 5.4.
• Secure with three fasteners on each side.
WARNING! Risk of Fire! DO NOT pack insulation around
the vent. Insulation must be kept back from the pipe to
prevent overheating.
D. Install Attic Insulation Shield
WARNING! Fire Risk. DO NOT allow loose materials or
insulation to touch vent. Hearth & Home Technologies
requires the use of an attic shield.
The International Fuel Gas Code requires an attic shield
constructed of 26 gauge minimum steel that extends at least
2 in. (51 mm) above insulation.
• Attic insulation shields must meet specified clearances to
combustible materials and be secured in place.
• An attic insulation shield kit is available from Hearth & Home
Technologies. Contact your dealer to order. Install attic
insulation shield according to instructions included with kit.
