Safety information Local Codes Continued 12. Do not use this fireplace to cook food or burn paper or other objects. 13. Do not use any solid fuels (wood, coal, paper, cardboard, etc.) in this fireplace. Use only the gas type indicated on fireplace nameplate. 14. This appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.1. 15.
Pre-Installation Preparation Location and space requirements Flush with a wall Determine the safest and most efficient location for your DESA direct-vent fireplace. Make sure that rafters and wall studs are not in the way of the venting system. Choose a location where the heat output is not affected by drafts, air conditioning ducts, windows or doors. Figure 2 shows some common locations.
Pre-Installation Preparation 1 2 Continued 3 A framing and finishing 4 Figure 4 shows typical framing of this fireplace. Figure 5 shows framing for corner installation. All minimum clearances must be met. For available accessories for this fireplace, see Accessories on page 31. If you are using a separate combustible mantel piece, refer to Figure 6 for proper installation height. You can install noncombustible mantels at any height above the fireplace.

Venting Installation Instructions NOTICE: Read these instructions completely before attempting installation. These models are tested and approved for use with DESA (directvent) pipe components and terminations. The venting system must terminate on the outside of the structure and can not be attached to a chimney or flue system serving a separate solid fuel or gas burning appliance. A direct-vent appliance must have its own venting system. DO NOT common vent this appliance.
Venting Installation instructions Female Locking Lugs Continued 2. 3. 4. 5. Direct vent pipe sections and components are designed with special twist-lock connections. Twist-Lock Procedure: The female ends of the pipes have locking lugs (indentations). These lugs will slide straight into matching slots on the male ends of adjacent pipes. Push pipe sections together and twist one section clockwise approximately one-quarter turn until the sections are fully locked (see Figure 8).
Venting Installation instructions Minimum Pipe Overlap 11/4" Continued 7. Slide the wall firestop over the vent pipe before connecting horizontal run to vent cap (see Figure 12). 8. Carefully move fireplace, with vent assembly attached, toward wall and insert vent pipe into horizontal termination. The pipe overlap should be a minimum of 11/4". 9. Slide wall firestop against interior wall surface and attach with screws provided. See Figure 13 for horizontal termination details. 10.
Venting Installation instructions Continued Horizontal Termination Configurations Figures 14 through 18 show different configurations and alternatives for venting with horizontal termination. Each figure includes a chart with critical minimum and maximum dimensions which MUST be met. IMPORTANT: If using a venting configuration of only horizontal venting with no vertical run, a 1/4" rise for every 12" of run toward the termination is required.
Venting Installation instructions Continued SNORKEL TERMINATION INSTALLATION Recommended Applications: • Installations requiring a vertical rise on building exterior • Any installation using snorkel termination to achieve one foot above ground Snorkel terminations are available for installations requiring a vertical rise on the exterior of the building. If installing snorkel termination below grade, you must provide proper drainage to prevent water from entering snorkel termination (see Figure 16).
Venting Installation instructions Continued installation for vertical termination Note: Vertical restrictor must be installed in all vertical installations. 1. 2. Determine the route your vertical venting will take. If ceiling joists, roof rafters, or other framing will obstruct the venting system, consider an offset (see Figure 19) to avoid cutting load bearing members.

Venting Installation instructions Continued High Altitude Installation Your DESA direct-vent fireplace has been CSA tested and approved for elevations from 0-2000 feet (USA) and elevations from 0-4500 feet (Canada). When installing this fireplace at an elevation above 2000 feet (in the USA), you may need to decrease the input rating by changing the existing burner orifice to a smaller size. Reduce input 4% for each 1000 feet above sea level.
Fireplace Installation CHECK GAS TYPE Use proper gas type for the fireplace unit you are installing. If you have conflicting gas types, do not install fireplace. See retailer where you purchased the fireplace for proper fireplace according to your gas type. Installing optional blower accessories NOTICE: The CHDV42NR model fireplace comes with the BKT Blower already installed as standard equipment. If you have a CHDV42NR model fireplace, proceed to Installing Gas Piping to Fireplace Locations, page 16.
Fireplace Installation Continued Model BKT Installation Note: When installing the BKT thermostatically-controlled blower, you must first secure the thermal switch bracket to the blower if it has not already been factory installed. 1. Place the green ground wire with ring terminal between the bottom hole on the thermal switch bracket and the top ear hole on the blower assembly. Insert the Phillips screw into all three pieces and tighten securely (see Figure 28). 2.
Fireplace Installation CSA Design-Certified Equipment Shutoff Valve with 1/8" NPT Tap* Continued For propane/LP connection only, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11" and 14" of water. If you do not reduce incoming gas pressure, fireplace regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 30.
Fireplace Installation Continued CHECKING GAS CONNECTIONS Pressure Testing Fireplace Gas Connections 1. 2. WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once. 3. 4. WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once. 5. 6. Open equipment shutoff valve (see Figure 33).
Fireplace Installation Continued Installing Optional Wireless handheld REMOTE CONTROL - HRC100 and HRC200 Series NOTICE: Use only alkaline batteries (not included).
