Drywall or combustible materials (mini- mum 1/2 inch thick) are designed to contact the non- combustible material/appliance as called out in Section 10 Finishing. This appliance has been thoroughly tested to minimize drywall cracking and/or the protrusion of screws “screw pops" when framed as shown below. Framing should be done in a manner similar to framing a window or door: Double-2x4/2x6 as a header for horizon- tal strength and utilizing Jack or Trimmer stud fastened to the King studs for vertical strength. If elevating the appliance, the base of the unit should also be constructed in a similar manner to prevent settling. Note: Refer to Section 10 for important information related to facing, drywall specifications and decorative front information. 01/29/2018 15Heat & Glo • COSMO42-IFT, COSMO32-IFT Installation Manual • 2491-980 Rev. C • 11/17 C. Constructing the Appliance Chase A chase is a vertical box-like structure built to enclose the gas appliance and/or its vent system. In cooler climates the vent should be enclosed inside the chase. NOTICE: Treatment of ceiling firestops and wall shield firestops and construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Therefore, you MUST check local building codes to determine the requirements to these steps. Chases should be constructed and insulated in the same manner as the thermal envelope of the home based on the code requirements for that climate zone to prevent air leakage and draft problems. The chase is an extension of the building thermal envelope. To further prevent drafts and air leakage, the wall shield and ceiling firestops should be caulked with caulk with a minimum of 300 ºF continuous exposure rating to seal gaps. Gas line holes and other openings should be caulked with caulk with a minimum of 300 ºF continu- ous exposure rating or stuffed with unfaced insulation. If the appliance is being installed on a cement surface, a layer of plywood may be placed underneath to prevent conducting cold up into the room. NOTICE: Install appliance on hard metal or wood surfaces extending full width and depth. DO NOT install directly on carpeting, vinyl, tile or any combustible material other than wood. WARNING! Risk of Fire! Maintain specified air space clearances to appliance and vent pipe: • Insulation and other materials must be secured to prevent accidental contact. • The chase must be properly blocked to prevent blown insulation or other combustibles from entering and making contact with fireplace or chimney. • Failure to maintain airspace may cause overheating and a fire. 01/29/2018 Heat & Glo • COSMO42-IFT, COSMO32-IFT Installation Manual • 2491-980 Rev.

Use of Flex Vent (SLP-FLEX Series 6-5/8 Inch) The flex vent must be supported with the spacing between support intervals not exceeding 4 feet, with no more than 1/2 inch sag between supports. A support is required at each change in venting direction, and in any location where it is necessary to maintain the necessary clearance to combustibles. A simple “up and out” installation (Figure 4.8) requires only enough support to maintain the necessary clearance to combustibles. However, the vent attachment point and the firestop loca- tion are considered to be supports. Figure 4.8 Flex Vent Pipe - Generic Fireplace Shown 3 in. CLEARANCE TERMINATIONCAP FLEX-VENT 1 in. CLEARANCE General Rules: • Elbows may be placed back to back anywhere in the system. • Any 90º elbow may be replaced with two back to back 45º elbows. • When penetrating a combustible wall, a wall shield firestop must be installed. • When penetrating a combustible ceiling, a ceiling firestop must be installed. • Horizontal runs of vent do not require vertical rise; horizontal runs may be level. • Horizontal termination cap should have a 1/4 inch downward slant to allow any moisture in cap to be released.

Venting Components The LINK-DV30B is approved for use with the coaxial/co- linear venting application. The LINK-DV30B kit includes: • Two 30 foot sections of flexible vent pipe (3 inches Ø). One section is used to draw combustion air and the other section is used to expel exhaust gases. • One vertical termination cap. WARNING! Risk of Fire! Coaxial to colinear venting con- figuration may only be used in existing non-combustible chimney. Installation in any other venting application could cause fire. Prior to installing the gas appliance: • Have the chimney and adjacent structure inspected and cleaned by qualified professionals. Hearth & Home Technologies recommends that NFI or CSIA certified professionals, or technicians under the direction of certi- fied professionals, conduct a minimum of a NFPA 211 Level 2 inspection of the chimney. • Replace component parts of the chimney and fireplace as specified by the professionals. • Ensure all joints are properly engaged and the chimney is properly secured. Stainless Steel Flex Requirement - COSMO32-IFT ONLY: The COSMO32-IFT model requires the use of a 3 ft. stain- less steel flex liner (468-380A) to be installed directly to the exhaust collar on the DV-46DVA-GCL connector. Coaxial to Colinear Venting The coaxial to colinear adapter (DV-46DVA-GCL) is ap- proved for installations into solid fuel masonry or factory built fireplaces that have been installed in accordance with the National, Provincial, State and local building codes. The DV-46DVA-GCL must be recessed into exist- ing masonry fireplace. See Table 1 and Figure 4.20. Table 1 CAUTION! DO NOT use any flue restrictor when vent- ing with the DV-46DVA-GCL adapter and LINK-DV30B kit. This could result in poor flame appearance, sooting, pilot malfunction, or overheating.

Comply with all minimum clear- ances to combustibles as specified. Framing closer than the minimums listed must be constructed entirely of noncom- bustible materials (i.e., steel studs, concrete board, etc.) The appliance is designed to accept 1/2 in. wall sheathing materials such as drywall, plywood, wood composites, or non-combustible materials. The type of material used depends whether the installation is an Inside or Overlap Fit Method. Refer to Section 10.D regarding installation details associated with the Inside and Overlap Fit methods. The factory-supplied non-combustible board must be used in all installations. It must be directly attached to structural framing adjacent to the appliance. Screw fas- teners should be installed in the pilot holes provided in the outer perimeter of the non-combustible board. See Figure 10.1 and Figure 10.2. The factory-supplied board is designed such that its edg- es will be at the approximate center of the adjacent fram- ing, assuming it is 1-1/2 in. nominal thickness. This will allow the wallboard joints to occur on the center of the framing where the panels can be fastened properly. If the framing thickness is less than 1-1/2 in. nominal, such as with formed steel systems, then it may be necessary to adjust the adjacent framing dimensions so that the non- combustible board and wallboard joints are centered on the framing. Finishing Instructions It is important to follow the framing and finishing instruc- tions to ensure proper placement of fireplace into the sur- rounding framing/finishing materials. Wall sheathing materials 1/2 in. thick are specified in this installation manual to properly align with the factory- installed non-combustible material. WARNING! Risk of Fire! DO NOT remove the factory- installed non-combustible board or cover it with combus- tible material, such as: • Drywall (gypsum board) • Plywood • Materials that do not meet the ASTM E 136 Non-com- bustibility standard (below). Removal of factory-installed, non-combustible board and/ or use of materials not meeting the ASTM E 136 standard may cause fire. • Facing and/or finishing materials must not interfere with air flow through decorative fronts. • Facing and/or finishing materials must never overhang into the glass opening. Non-Combustible Materials Specification Material which will not ignite and burn. Such materials are those consisting entirely of steel, iron, brick, tile, concrete, slate, glass or plasters, or any combination thereof. Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750 ºC. • Observe all clearances when applying combustible materials. WARNING! Risk of Fire! DO NOT apply combustible materials beyond the minimum clearances. Comply with all minimum clearances to combustibles as specified in this manual. Overlapping materials could ignite and will interfere with proper operation of decorative fronts. WARNING! Risk of Fire! DO NOT install drywall or other combustible materials over the factory-installed non-com- bustible board. Overlapping materials could ignite. Decorative facing material thickness is measured from the face of the factory-installed non-combustible board. See Section 10.D for Overlap Fit and Inside Fit require- ments. 01/29/2018 53Heat & Glo • COSMO42-IFT, COSMO32-IFT Installation Manual • 2491-980 Rev. C • 11/17 B. Non-Combustible Board and Drywall In- stallation Introduction If the desired finished fireplace installation does not utilize non-combustible finishing materials (such as tile, marble, stone, etc.), special attention must be paid to the instal- lation of drywall/gypsum wallboard to minimize potential development of cracking and paint discoloration. Hearth and Home Technologies has tested the following methods and materials and therefore recommends the following steps for the best drywall performance. Attaching Non-Combustible Board to Framing 1. To ensure the lower cover panel has been correctly installed, verify that two screws (total) have been in- stalled in the lower left and right sides of the fireplace opening. See Figure 8.1. These screws, when in- stalled, will ensure the lower panel is correctly installed. If the lower cover panel is not correctly installed, the decorative front may not fit into the fireplace opening correctly. Refer to section 6.D for more information regarding the included non-combustible board. 2. The appliance ships with the required non-combus- tible board. The large top piece of non-combustible board is pre-installed at the factory. The narrow left and right non-combustible pieces are shipped within the appliance. Install the non-combustible side pieces with the screws provided in the manual bag assembly. There are pilot holes located on the left and right side columns. Care should be taken not to tighten these screws into the non-combustible board excessively. Set screws flush to the face of the non-combustible board. See Figure 10.2 and Section 6.D. 3. The outer perimeter of the factory-installed non-com- bustible board has pre-drilled pilot holes. See Figure 10.1. Secure the non-combustible board to adja- cent framing with drywall screws that are a minimum of 1-1/4 inch in length. Care should be taken not to tighten these screws into the non-combustible board excessively. Set screws flush to the face of the non- combustible board. See Figure 10.2 and Section 6.D. 4. When installing drywall around the appliance, install a rectangular hole for the fireplace/non-combustible board in a single sheet of drywall. This will minimize the joints that require finishing adjacent to the fireplace opening. Ensure that the 1/8 inch gap is maintained between the factory installed non-combustible board and the surrounding drywall. See Figure 10.1. Secure the drywall to the framing with screws a minimum of one inch in length every six inches across the top of the fireplace and every ten inches on the sides of the fireplace. 5. To ensure good adhesion of drywall compounds and tape, thoroughly clean the non-combustible board and surrounding drywall to remove dust. PRE-DRILLED PILOT HOLES APPLIANCE OPENING FILL GAPS Figure 10.1 Install Non-Combustible Board Filling and Finishing Seams 1. Fill all gaps and joints between the non-combustible board pieces and the drywall with a general purpose chemically hardening joint compound. Hearth and Home Technologies recommends Durabond® 45 Joint Compound manufactured by USG (Sheetrock® brand). Use a drywall knife to firmly press the joint compound into all gaps. See Figure 10.1. Allow these joints to dry. 2. All joints are to be taped with a paper tape and embed- ded with Durabond® 45 Joint Compound manufac- tured by USG (Sheetrock® brand). Allow these joints and paper tape to dry. 3. Depending on the technique used in steps 1 and 2, two to three finishing coats are required to provide a smooth and durable finish. Hearth and Home Tech- nologies recommends ProForm® Lite-Blue Joint Com- pound manufactured by National Gypsum. Allow each coat to properly cure. Allow the finishing coat(s) to cure for 24 hours before operating appliance. Painting If desired finishing includes a painted wall, a high-quality 100% acrylic latex paint with a high-quality latex primer base coat are recommended around the appliance to limit discoloration. Oil-based or standard acrylic paints may be more prone to discoloration due to heat exposure. Drywall Joint-Crack Prevention and Repair Drywall joints around the fireplace will be affected by ex- posure to elevated temperatures, along with other envi- ronmental, structural factors due to new construction, and methods used to install and finish the drywall. If a crack does emerge adjacent to the fireplace, it can be perma- nently repaired by filling it with a paintable latex caulk, followed by repainting. Some movement of the screws used to secure the non- combustible board to the appliance/surround framing is expected. If a blemish begins to show over a screw head, sand the surface to remove the blemish and repaint.01/29/2018 Heat & Glo • COSMO42-IFT, COSMO32-IFT Installation Manual • 2491-980 Rev. C • 11/1754 WARNING! Risk of Fire! Maintain specified air space clearances to combustibles. Failure to comply with these instructions may cause a fire or cause the appli- ance to overheat. CAUTION! Risk of Glass Damage and Cuts! DO NOT drill or install any type of screw or fastener into the lower cover panel. Sharp screw or fastener tips may penetrate and break the glass or cause cuts. Note: It is acceptable to use a silicone sealant with a minimum of 300 ºF continuous exposure rating to adhere drywall to lower cover panel. The final fireplace installation can be accomplished by either the Overlap Fit or Inside Fit method. Reference Section 10.D regarding installation details associated with the Inside Fit and Overlap Fit methods. It is acceptable to pre-drill holes and use self-tapping screws in the installed non-combustible board to attach non-combustible backer board for tile, marble, etc. Refer to Figure 10.2 for acceptable screw or metal lath location and screw length requirements. Do not drill or install screws which may penetrate the lower cover panel as this will restrict required access to the glass, battery-backup, and control module. See Figure 10.2. Note: If the desired look is painted drywall, it is recommended that no additional screws are installed into the factory-provided non-combustible board. Only install the screws provided into the pilot holes located in the factory-provided non-combustible board. Figure 10.2 Finishing Details - COSMO42-IFT and COSMO32-IFT WARNING! Risk of Fire!
