- C. Approved Pipe This appliance is approved for use with Hearth & Home Technologies DVP venting systems. Refer to Section 12.A for vent component information and dimensions. DO NOT mix pipe, fittings or joining methods from different manufacturers. The pipe is tested to be run inside an enclosed wall. There is no requirement for inspection openings at each joint within the wall. WARNING! Risk of Fire or Asphyxiation. This appliance requires a separate vent. 
- D. Use of Elbows Diagonal runs have both vertical and horizontal vent aspects when calculating the effects. Use the rise for the vertical aspect and the run for the horizontal aspect. See Figure 4.4. Y Two 45º elbows may be used in place of one 90º elbow. On 45º runs, one foot of diagonal is equal to 8-1/2 in. (216 mm) horizontal run and 8-1/2 in. (216 mm) vertical run. A length of straight pipe is allowed between two 45º elbows. See Figure 4.4. Figure 4. 
- E. Measuring Standards F. Vent Diagrams Vertical and horizontal measurements listed in the vent diagrams were made using the following standards: General Rules: • Pipe measurements are shown using the effective length of pipe. See Section 12.A for information on effective length of pipe components. • Horizontal terminations are measured to the outside mounting surface (flange of termination cap) (see Figure 4.6). • Vertical terminations are measured to top of last section of pipe. See Figure 4.7. 
- WARNING Fire Risk. Explosion Risk. Do NOT pack insulation or other combustibles between ceiling firestops. • ALWAYS maintain specified clearances around venting and firestop systems. • Install wall shield and ceiling firestops as specified. Failure to keep insulation or other material away from vent pipe could cause fire. WARNING! Risk of Fire! Top Vent - Horizontal Termination Venting with 1 elbow DO NOT attach elbow directly to the appliance.

- 5 Vent Clearances and Framing A. Pipe Clearances to Combustibles B. Wall Penetration Framing/Firestops WARNING! Risk of Fire! Maintain air space clearance to vent. DO NOT pack insulation or other combustibles: Combustible Wall Penetration Whenever a combustible wall is penetrated, you must frame a hole for the wall shield firestop(s). The wall shield firestop maintains minimum clearances and prevents cold air infiltration. 
- C. Install the Ceiling Firestop A ceiling firestop MUST be used between floors and attics. • DVP pipe only - Frame an opening 10 in. by 10 in. (254 mm by 254 mm) whenever the vent penetrates a ceiling/fl oor. See Figure 5.3. ATTIC ABOVE • Frame the area with the same sized lumber as used in ceiling/floor joist. A • The ceiling firestop may be installed above or below the ceiling joists when installed with an attic insulation shield. It must be under joists between floors that are not insulated. 
- E. Installing the Optional Heat-Zone® Gas Kit • Locate the Heat-Zone® ports on the left and right sides of the appliance. See Figure 5.5. Remove the knockouts from the appliance with a tin snips. • Place the Heat-Zone® adapter box into position prior to the final positioning of the fireplace as shown in Figure 5.5. Secure using eight self-tapping screws. Ensure the Heat-Zone® knockouts are completely covered by the adapter box. 
- 6 Appliance Preparation CAUTION! Risk of Cuts, Abrasions or Flying Debris. Wear protective gloves and safety glasses during installation. Sheet metal edges are sharp. A. Top Standoff Preparation 1. Rotate the four (4) top standoffs up into vertical position. Push the standoff support tab on each standoff toward the center of the appliance and fasten it in place using the supplied screw and pilot hole. See Figure 6.1. 3. Place a vent section on the starting collar. 
- C. Securing and Leveling the Appliance Setting the Fireplace into the Framing WARNING! Risk of Fire! Prevent contact with: The left and right nailing tabs were designed as a means to ensure the fireplace is mounted flush with the framing materials. See Figures 6.5-6.7. • Sagging or loose insulation • Insulation backing or plastic • Framing and other combustible materials Block openings into the chase to prevent entry of blownin insulation. Make sure insulation and other materials are secured. 
- D. Installing Non-Combustible Facing Material WARNING! Risk of Fire! • Follow these instructions exactly. • Facing materials must be installed properly to prevent fire. • No materials may be substituted without authorization by Hearth & Home Technologies. • Remove protective cardboard sleeve from noncombustible facing pieces, which are included with the appliance. • Install non-combustible facing material to the appliance using the 1-1/4 inch screws supplied in the manual bag assembly. 
- 7 Venting and Chimneys A. Assemble Vent Sections Attach Vent to the Firebox Assembly Note: The end of the pipe sections with the lanced tabs will face toward the appliance. Attach the first pipe section to the starting collar: • Lanced pipe end of the starting collar. • Inner pipe over inner collar. • Push the pipe section until all lanced tabs snap in place. • Lightly tug on pipe to confirm it has locked. 
- B. Assemble Slip Sections C. Secure The Vent 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 7.5. • Vertical runs originating off the top of the appliance, with no offsets, must be supported every 8 ft. (2.44 m) after the maximum allowed 25 ft. (7.62 m) of unsupported rise. • Slide together to the desired length. 
- D. Disassemble Vent Sections • Rotate either section (see Figure 7.9) so the seams on both pipe sections are aligned as shown in Figure 7.10 • Pull carefully to separate the pieces of pipe. Figure 7.9 Rotate Seams for Disassembly Figure 7.10 Align and Disassemble Vent Sections Majestic • ECHEL36IN/STIN, ECHEL48IN/STIN, ECHEL60IN, ECHEL72IN Installation Manual • 2406-970 Rev. 
- E. Vertical Termination Requirements Install Metal Roof Flashing • See minimum vent heights for various pitched roofs (Figure 7.11) to determine the length of pipe to extend through the roof. CAULK • Slide the roof flashing over the pipe sections extending through the roof as shown in Figure 7.12. HORIZONTAL OVERHANG 2 FT. MIN. 20 INCHES MIN. LOWEST DISCHARGE OPENING Assemble and Install Storm Collar GAS DIRECT VENT TERMINATION CAP X 12 ROOF PITCH IS X/ 12 H (MIN. 
- Install Vertical Termination Cap F. Horizontal Termination Requirements • Attach the vertical termination cap by sliding the inner collar of the cap into the inner flue of the pipe section while placing the outer collar of the cap over the outer flue of the pipe section. Heat Shield Requirements for Horizontal Termination • Secure the cap by driving three self-tapping screws (supplied) through the pilot holes in the outer collar of the cap into the outer flue of the pipe. See Figure 7.14. 
- Install Horizontal Termination Cap WARNING! Risk of Fire! The telescoping flue section of the termination cap MUST be used when connecting vent. • 1-1/2 (38 mm) minimum overlap of flue telescoping section is required. Failure to maintain overlap could cause overheating and fire. • Vent termination must not be recessed in the wall. Siding may be brought to the edge of the cap base. • Flash and seal as appropriate for siding material at outside edges of cap.
