Framing

This appliance is designed to be recessed into combustible framing with non-combustible material pre-installed on top and side. Drywall or combustible materials (minimum 1/2 inch thick) are designed to contact the noncombustible 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 horizontal strength and utilizing Jack or Trimmer stud fastened to the King studs for vertical strength.

If elevating the appliance, the base of the appliance should also be constructed in a similar manner to prevent settling.

Refer to Figures 3.7, 3.8 and 3.9 for information regarding framing when the Passive Heat Kit is installed. Install the Passive Heat Kit per the instructions provided with the kit.

Note: Refer to Section 10 for important information related to facing, drywall specications and decorative barrier front information.

C. Constructing the Appliance Chase

NOTICE: Install appliance on hard metal or wood surfaces extending full width and depth. DO NOT install directly on carpeting, vinyl, or any combustible material other than wood.

WARNING! Risk of Fire! Maintain specied 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 replace or chimney.

• Failure to maintain airspace may cause overheating and a re.

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 restops and wall shield restops 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.

NOTICE: Where required by code, install only sprinkler heads with a sprinkler activation temperature classied as Extra High.

• Sprinklers inside of chase: Keep sprinkler head away from vent and chimney.

• Heat Management applications: Maintain 36 inches of clearance to openings from which heat is discharged such as convection slots, passive heat registers, heat zone registers, etc. Refer to Section 6.B for Heat Management options allowed for this appliance.

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 restops should be sealed with caulk with a minimum of 300 ºF continuous exposure rating to seal gaps. Gas line holes and other openings should be sealed with caulk with a minimum of 300 ºF continuous exposure rating or stu󰀨ed 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.

Minimum height requirements for an exterior chase on a topvented appliance are shown in Figure 3.12. Reference Figure 4.5 for additional clearances.

Measuring Standards:

Vertical and horizontal measurements listed in the vent diagrams and clearances for termination were made using the following standards:

• Pipe measurements are shown using the e󰀨ective length of pipe. See Section 12.A (Figure 12.1) for information on e󰀨ective length of pipe components.

• Horizontal terminations are measured to the outside mounting surface (flange of termination cap). See Figure 4.8.

• Vertical terminations are measured to top of last section of pipe. See Figure 4.9.

• Horizontal pipe installed level with no rise.

E. Use of Flex Vent (SLP-FLEX Series 6-5/8

Inch)

The ex 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 4.10) requires only enough support to maintain the necessary clearance to combustibles. However, the vent attachment point and the restop location are considered to be supports.

Exhaust Restrictor Instructions

Exhaust restrictors are recommended for these verti-

cally terminated products which have excessive draft.

Exhaust restrictors will compensate for high draft, and

restore visual ame height. If the vent conguration has

a total vertical of 15-60 feet, an exhaust restrictor may

be needed. The exhaust restrictor can be located in the

appliance manual bag.

Exhaust Restrictor Installation

1. COSMO42-IFT-B/COSMO36-IFT-B Only: Remove inner heat shield by removing two wing nuts from top front of heat shield and two screws that secure the heat shield to back wall of replace. Retain heat shield and fasteners.

2. ALL SIZES: Center the exhaust restrictor in the open end of the exhaust outlet and secure through the slots on the exhaust restrictor with the two 1/4 in. self-tapping screws provided in the appliance manual bag. See Figure 4.17.

3. COSMO42-IFT-B/COSMO36-IFT-B Only: Reinstall shield by securing it with the two wing nuts and two screws previously removed in Step 1.

Risk of Fire!

DO NOT apply combustible materials beyond the min-

imum clearances. Comply with all minimum clearances to combustibles as specied in this manual. Materials overlapping into non-combustible zones could ignite and will interfere with air ow through decorative barrier fronts.

• Metal front of appliance may be covered with noncombustible materials only.

• Facing and/or nishing materials must not interfere with air ow through decorative barrier fronts, removal of decorative barrier fronts or access for service.

• Facing and/or finishing materials must never overhang into the glass opening.

• Observe all clearances when applying combustible materials.

• Seal gaps between the nished wall and appliance top and sides using a 300 ºF minimum sealant. Refer to Figure 10.1 and Figure 10.2.

NOTICE: Surface temperatures around the appliance will become warm while the appliance is in operation. Ensure finishing materials used for all surfaces (floor, walls, mantels, etc.) will withstand temperatures up to 190°F.

WARNING! Risk of Fire! Comply with all minimum clearances to combustibles as specied. Framing closer than the minimums listed must be constructed entirely of noncombustible 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 fasteners 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 edges will be at the approximate center of the adjacent framing, 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 noncombustible board and wallboard joints are centered on the framing.

Finishing Instructions

It is important to follow the framing and nishing instructions to ensure proper placement of replace into the surrounding framing/nishing materials.

Wall sheathing materials 1/2 in. thick are specied in this installation manual to properly align with the factoryinstalled non-combustible material.

WARNING! Risk of Fire! DO NOT remove the factoryinstalled non-combustible board or cover it with combustible material, such as:

• Drywall (gypsum board)

• Plywood

• Materials that do not meet the ASTM E 136 Noncombustibility standard (below).

Removal of factory-installed, non-combustible board and/ or use of materials not meeting the ASTM E 136 standard may cause re.

• Facing and/or nishing materials must not interfere with

air ow through decorative barrier fronts.

• Facing and/or nishing materials must never overhang

into the glass opening.

• 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 specied in this manual. Overlapping materials could ignite and will interfere with proper operation of decorative barrier fronts.

WARNING! Risk of Fire! DO NOT install drywall or other combustible materials over the factory-installed noncombustible 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 requirements.

Introduction

If the desired nished replace installation does not utilize non-combustible nishing materials (such as tile, marble, stone, etc.), special attention must be paid to the installation of drywall/gypsum wallboard to the side joints of the non-combustible board 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 installed in the lower left and right sides of the replace opening. See Figure 8.1. These screws, when installed, will ensure the lower panel is correctly installed. If the lower cover panel is not correctly installed, the decorative barrier front may not t into the replace opening correctly. Refer to section 6.D for more information regarding the included non-combustible board.

2. The appliance ships with the required non-combustible 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 ush 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-combustible board has pre-drilled pilot holes. See Figure

10.1. Secure the non-combustible board to adjacent 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 ush to the face of the noncombustible board. See Figure 10.2 and Section 6.D.

4. When installing drywall around the appliance, install a rectangular hole for the replace/non-combustible board in a single sheet of drywall. This will minimize the joints that require nishing adjacent to the replace 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 replace and every ten inches on the sides of the replace.

Heat & Glo • COSMO32-IFT-B, COSMO36-IFT-B, COSMO42-IFT-B Installation Manual • 2619-980 Rev. L • 2/21

5. To ensure good adhesion of drywall compounds and tape, thoroughly clean the non-combustible board and surrounding drywall to remove dust. The non-combustible board may be primed with a high-quality PVA primer.

PRE-DRILLED PILOT HOLES

Figure 10.1 Install Non-Combustible Board

Filling and Finishing Seams

1. Step 1: Fill all gaps and joints between the noncombustible board pieces and the drywall with a general purpose chemically setting joint compound such as Durabond® 45 Joint Compound manufactured by USG (Sheetrock® brand), recommended by Hearth & Home Technologies. Use a drywall knife to rmly press the joint compound into all gaps. See Figure

10.1. Allow these joints to dry.

2. Step 2: All joints are to be taped with berglass mesh tape 1 7/8” minimum width, and embedded with Setting-Type joint compound, such as with Durabond® Joint Compound manufactured by USG (Sheetrock® brand), or equivalent. Allow these joints to dry.

3. Step 3: Depending on the technique used in steps 1 and 2, two to three nishing coats are required to provide a smooth and durable nish. Hearth and Home Technologies recommends a lightweight or allpurpose compound. Allow each coat to properly cure. Allow the nishing coat(s) to cure for 24 hours before operating appliance.

NOTICE: Hearth & Home Technologies recommends

using multiple pieces of decorative nish material around the opening of the appliance to reduce the chances of the material cracking. A single piece of decorative nish material (such as marble or granite) is more susceptible to cracking due to uneven heating and cooling which causes temperature dierentials within the material itself. The use of multiple pieces will reduce the temperature dierentials in each piece and reduce the likelihood of cracks. In addition to using multiple pieces of decorative nish material, the installation of the Passive Heat optional heat management system will also reduce the chances of cracking.

Page 61

Painting

If desired nishing 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 replace will be a󰀨ected by exposure to elevated temperatures, along with other environmental, structural factors due to new construction, and methods used to install and nish the drywall. If a crack does emerge adjacent to the replace, it can be permanently repaired by lling it with a paintable latex caulk, followed by repainting.

Some movement of the screws used to secure the noncombustible 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.

WARNING! Risk of Fire! Maintain specied air space clearances to combustibles. Inadequate air space could cause overheating and re.

WARNING! Risk of Fire! Maintain specied air space

clearances to combustibles. Failure to comply with these instructions may cause a re or cause the appliance 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.

The nal replace 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.

I. Fixed Glass Assembly Removal and Re-

placement

WARNING! Risk of Asphyxiation! Handle xed glass assembly with care. Inspect the gasket to ensure it is undamaged and inspect the glass for cracks, chips or scratches.

• DO NOT strike, slam or scratch glass.

• DO NOT operate replace with glass removed, cracked,

broken or scratched.

• Replace as a complete assembly.

Removing Fixed Glass Assembly

1. Remove the decorative front.

2. The glass assembly has two upper spring latches and two lower spring latches. See Figure 11.3. Locate the two spring latches that are on the upper left and right of the replace.

3. Pull upper spring latch on one side forward to release glass assembly while supporting glass assembly with opposite hand. Repeat for the other upper spring latch always taking care to support the glass assembly with one hand.

4. Grasp glass on the upper right and left sides and remove glass assembly by lifting “up” and “out”.

Note: Observe the presence of a space or gap between the glass latch and the front of the appliance where the bottom of the glass assembly is positioned. This gap is designed for positive placement when replacing the glass assembly. See Figure 11.3.

Replacing Fixed Glass Assembly

The bottom glass latches have been designed to create a small gap between the glass clip and the face of the appliance. See Figure 11.3.

1. Install the bottom of the glass assembly so that the two tabs on the bottom of the glass latch engage the gap. By tilting the top of the glass towards the face of the appliance, tension will be applied to the bottom two glass latches. Use one hand to support the glass at all times.

2. Fasten the two upper glass latches, one at a time, by pulling out and downward into position on the glass assembly. Use one hand to support the glass at all times.

3. Verify that the top two glass latches are engaged by visually verifying that glass latches have engaged both left and right tabs on the glass frame.

4. Verify the bottom two glass latches have engaged the glass frame tabs by grasping the bottom of the glass frame assembly and pulling the glass frame assembly “away” from the face of the appliance and “release” the glass frame. The spring action of the clips will “pull” the glass frame assembly towards the face of the appliance if bottom clips are properly engaged. If the glass frame assembly does not pull back towards the face of the appliance, repeat steps 1-4.
