Resumen del manual
Commercial, Multi-family (Multi-level exceeding two stories), or High-Rise Applications For Installation into a commercial, multi-family (multi-level exceeding two stories) or high-rise applications: All outer pipe joints must be sealed with high temperature silicone, including the slip section that connects directly to the horizontal termination cap. • Apply a bead of silicone sealant inside the female outer pipe joint prior to joining sections. See Figure 8.1. • Only outer pipes need to be sealed. All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed in this manner, unless otherwise stated. WARNING! Risk of Fire or Explosion! DO NOT break silicone seals on slip sections. Use care when removing termination cap from slip pipe. If slip section seals are broken during removal of the termination cap, vent may leak. Note: Align seams to engage pipe, then rotate counterclockwise to lock Figure 8.5 Adding Venting Components C. Assemble Slip Sections • Slide the inner flue of the slip section into the inner flue of the pipe section and the outer flue of the slip section over the outer flue of the pipe section. See Figure 8.6. • Slide together to the desired length. Pilot holePilot hole Figure 8.6 Slip Section Pilot Holes • Maintain a 1-1/2 in. (38 mm) overlap between the slip section and the pipe section. • Secure the pipe and slip section with two screws no longer than 1/2 in. (13 mm), using the pilot holes in the slip section. See Figure 8.7. Figure 8.7 Screws into Slip Section • Continue adding pipe as necessary following instructions in “Assembling Pipe Sections.” NOTICE: If slip section is too long, the inner and outer flues of the slip section can be cut to the desired length. NOTICE: When installing a vent system with an HRC termination cap, all pipe system joints shall be sealed using a high temperature silicone sealant. • Apply a bead of silicone sealant inside the female outer pipe joint prior to joining sections. • Only outer pipes are sealed, sealing the inner flue is not required. • All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed. Heat & Glo • 6000G, 6000G-IPI • 2103-900 Rev. M • 9/08 D. Secure the Vent Sections • Vertical runs of DVP pipe must be supported every 8 ft. (2.44 m) after the 25 ft. (7.62 m) maximum unsupported rise. • Vertical runs of SLP pipe must be supported every 8 ft. (2.44 m). • Horizontal sections must be supported every 5 feet (1.52 m). • Vent supports or plumbers strap (spaced 120. apart) may be used to support. See Figures 8.8 and 8.9. • Wall shield firestops may be used to provide horizontal support. • SLP ceiling firestops have tabs that may be used to provide vertical support. WARNING! Risk of Fire, Explosion or Asphyxiation! Improper support may allow vent to sag and separate. Use vent run supports and connect vent sections per installation instructions. DO NOT allow vent to sag below connection point to appliance. E. Disassemble Vent Sections • Rotate either section (see Figure 8.10) so the seams on both pipe sections are aligned as shown in Figure 8.11. • Pull carefully to separate the pieces of pipe. Figure 8.10 Rotate Seams for Disassembly Figure 8.8 Securing Vertical Pipe Sections Figure 8.9 Securing Horizontal Pipe Sections Figure 8.11 Align and Disassemble Vent Sections Heat & Glo • 6000G, 6000G-IPI • 2103-900 Rev. M • 9/08 F. Install Decorative Ceiling Components (SLP only) A decorative ceiling thimble can be installed on a fl at ceiling through which the vent passes. The decorative ceiling thimble is used to cover the firestop. • Seal the gap between the vent pipe and fi restop using high temperature silicone to prevent cold air infiltration. • Install the decorative ceiling thimble by sliding it up to the ceiling and attaching it using the provided screws. A decorative cathedral ceiling support box can be installed on a cathedral ceiling through which the vent passes. • Use a plumb-bob to mark the center line of the venting system on the ceiling and drill a small hole through the ceiling and roof at this point. Locate the hole and mark the outline of the cathedral ceiling support box on the outside roof. • Remove shingles or other roof covering as necessary to cut the rectangular hole for the support box. Cut the hole 1/8 in. (3 mm) larger than the support box outline. • Lower the support box through the hole in the roof until its bottom is at least 2 in. (51 mm) below the ceiling (Figure 8.12). • Level the support box both vertically and horizontally and temporarily tack it in place through the inside walls into the roof sheathing. • Use tin snips to cut the support box from the top corners down to the roof line and fold the resulting flaps to the roof. See Figure 8.13. • Nail the flaps to the roof AFTER running a bead of non hardening sealant between the flaps and the roof. WARNING! Risk of Fire! Clean out ALL materials from inside the support box and complete the vertical vent run and termination. LEVEL CAT...
