6Vent Clearances and FramingA. Pipe Clearances to CombustiblesWARNINGFire RiskExplosion RiskMaintain vent clearance to combustibles asspecifi ed.• Do not pack air space with insulation orother materials.Failure to keep insulation or other materialsaway from vent pipe may cause fi re.Note: Heat shields MUST overlap by a minimum of 1-1/2 in.(38 mm). The heat shield is designed to be used on a wall4 in. to 7-1/4 in. (102 mm to 184 mm) thick. If wall thicknessis less than 4 in. (102 mm) the existing heat shields must befield trimmed. If wall thickness is greater than 7-1/4 in. (184mm) a DVP-HSM-B will be required.HeatShield3 in.

This shield maintainsminimum clearances and restricts cold air infi ltration.• If the wall being penetrated is of noncombustible materials(material which will not ignite or burn, or has a UL fire ratingof zero), a 9 in. (229 mm) diameter hole is acceptable.• Whenever a wall is penetrated the wall shield fi restopis only required on one side and no heat shield isnecessary.• If your local inspector requires the wall shield fi restop onboth sides of the wall, then both wall shield fi restops musthave a heat shield attached to them.The center of theframing hole is1 in.

C. Install the Ceiling Firestop• Frame an opening 10 in. by 10 in. whenever the ventsystem penetrates a ceiling/fl oor (see Figure 6.4).• Frame the area with the same sized lumber as used inceiling/fl oor joist.• When installing a top vent vertical termination appliancethe hole should be directly above the appliance, unlessthe fl ue is offset.• The ceiling fi restop may be installed above or below theceiling. Refer to Figure 6.5.• Secure with three fasteners on each side.• Do not pack insulation around the vent. Insulation mustbe kept away from the pipe.<strong>At</strong>tic Above10 in.
