Initial Installation QUALIFIED INSTALLERS ONLY INTRODUCTION: This section of the owner’s manual is for the use of qualified technicians only. Fireplace placement, hearths, facings, mantles, and venting terminations will be covered, as well as the gas and electric systems. There are several installation safety guidelines that must be adhered to. Please carefully read the safety precautions at the front of this manual. Warning: Clearances must be sufficient to allow access for maintenance and service.
Initial Installation QUALIFIED INSTALLERS ONLY CORNER INSTALLATION: The dimensions for installing a fireplace in the corner of a room are given below in Figure 11. 50 7/8" (1292mm) 21 3/4" (552mm) 15 3/8" (391mm) 1 1/4" (32mm) 36" (914mm) 21 1/2" (546mm) 13 1/2" (343mm) 45" (1143mm) 72 3/8" (1838mm) Figure 11. Dimensions for a corner installation.
Initial Installation QUALIFIED INSTALLERS ONLY If the unit is raised 4” (102mm) or less it is mandatory to have a hearth installed with a protector pad (sheet metal) placed directly on the floor or hearth framing, with the cement board (see specs below) on top of it. Tile, or another non-combustible material forms the top layer of the hearth. A decorative trim may be added to the edge of the hearth.
Initial Installation QUALIFIED INSTALLERS ONLY MANTLE CLEARANCES: It is not necessary to install a mantle, but if one is desired it is important to follow the guidelines shown in Figure 16.
Initial Installation QUALIFIED INSTALLERS ONLY VENT TERMINATION RESTRICTIONS: N O H D E L B C B B Fixed Closed F Openable B G Fixed Openable Closed A Termination Cap G M J Air Supply Inlet G Gas Meter K I Restriction Zone A (Termination not allowed) Figure 17. Vent Termination Restrictions, refer to Table 2. Table 2: Vent termination clearances, refer to Figure 17.
Initial Installation QUALIFIED INSTALLERS ONLY VENTING: This fireplace has been tested and certified for use with SIMPSON DURAVENT DIRECT VENT TYPE “GS” PIPE FOR GAS STOVES, SECURITY CHIMNEY’S SECURE VENT DIRECT VENT SYSTEM kits, and MDV SELKIRK METALBESTOS. A 1” (25 mm) clearance to combustibles must be maintained around any vertical vent pipe. Around a horizontal vent pipe, the clearance to combustibles should be 2” (51 mm) above and 11⁄2” (38 mm) on the sides and bottom.
Initial Installation QUALIFIED INSTALLERS ONLY VENT CONFIGURATIONS AND RESTRICTOR SETTINGS: Figures 20 shows the range of venting options, it shows possible vent configurations if the unit is top vented, for vertical and horizontal terminations, any layout that remains within the shaded area is acceptable. Having the fewest number of elbows is ideal, as they tend to disrupt air movement. Using 45˚ elbows is preferable to using 90˚ elbows. Also, a shorter vent system will perform better than a longer one.
Initial Installation QUALIFIED INSTALLERS ONLY HORIZONTAL TERMINATION: NOTES: 1. Horizontal pipes must not be level. For every 12 inches (305 mm) of horizontal travel (away from the stove), there should be at least 1⁄4 inch (6.4 mm) of vertical travel. Never allow the vent to run downward, as this could cause high temperatures or even present the possibility of a fire. 2. The exterior of the horizontal vent termination must not be blocked or obstructed. 3.
Initial Installation QUALIFIED INSTALLERS ONLY NOTE: For Simpson Duravent only, place a bead of Mil-Pac or Rutland No 78 Stove and Gasket Cement on the outer edge of the inner exhaust pipe (non-flared end). Push the pipe sections together, then twist about 1⁄4 turn, making sure the two sections are fully locked. Wrap all seams with foil ducting tape. Step 4. With the hole now framed, the wall thimble installed, and the pipe extending into the wall, proceed to the outside.
Initial Installation QUALIFIED INSTALLERS ONLY STEP 5. Cut hole in the roof centered on the small hole placed in the roof from Step 2. The hole should be of sufficient size to meet minimum requirements for Clearance to Combustibles, as specified. Continue to assemble lengths of pipe and elbows necessary to reach from the ceiling support box up through the roof line. Galvanized pipe and elbows may be utilized in the attic, as well as above the roof line.
Initial Installation QUALIFIED INSTALLERS ONLY NOTES: (1) If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3 feet (914 mm), to avoid excessive stress on the elbows, and possible separation. Wall straps are available for this purpose (see Figure 25). plumber’s tape connected to wall strap (2) When ever possible, use 45° degree elbows instead of 90° degree elbows.
Initial Installation QUALIFIED INSTALLERS ONLY DUCTING: The option of ducting allows heat from the fireplace to be transferred to a different area. The maximum total length for the ducting is 20 feet (6.1 m). There are four (4) duct outlets that can be used (see Figure 27), however, the blower puts out 200 cfm no matter how many ducts are used. Therefore, the more ducts there are, the less air goes through each one.
Initial Installation QUALIFIED INSTALLERS ONLY ELECTRICAL REQUIREMENTS: The fireplace must be electrically connected and grounded in accordance with local codes or, in the absence of local codes, with the current CSA C22.1 CANADIAN ELECTRICAL CODE Part 1, SAFETY STANDARDS FOR ELECTRICAL INSTALLATIONS, OR THE NATIONAL ELECTRICAL CODE ANSI / NFPA 70 in the US. WARNING: The electrical grounding instructions must be followed.
