Initial Installation QUALIFIED INSTALLERS ONLY Mantel Clearances: It is not necessary to install a mantel, but if one is desired it is important to follow the guidelines shown in Figure 22. The Manor face has a different set of mantel clearances than the other faces, see Figure 23.
Initial Installation QUALIFIED INSTALLERS ONLY Table 2: Vent termination clearances, refer to Figure 24. Letter Canadian Installation 1 A B US Installation2 12 in (30 cm) 12 in (30 cm) Description Clearance above grade, verandah, porch, deck, or balcony. 9 in (23 cm) Clearance from window or door that may be opened. C 12 in (30 cm)* Clearance from permanently closed window (to prevent condensation).
Initial Installation QUALIFIED INSTALLERS ONLY INSTALLATION INSTRUCTIONS: 1. Plan your installation and clearances to combustibles. Decide on a location for the unit that will meet the clearances noted in the venting section, and any or all local code requirements. Wire spacers 2. Set the appliance in the desired location. Determine if any wall studs, electrical wiring, or plumbing pipes are in the way of the venting system as it passes through the exterior wall.
Initial Installation QUALIFIED INSTALLERS ONLY 9. Install the flex pipe assembly through the wall thimble, ensure that this portion of pipe slides through the outside wall far enough to connect onto the vent termination cap. 10. Apply a bead of Mill-Pac Black sealant to the top section of the Ø4” (10 cm) by 5” (12.5 cm) flue collar adaptor previously installed into the fireplace flue outlet.

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, AMERICAN METAL PRODUCTS AMERIVENT DIRECT and DIRECT-TEMP SELKIRK METALBESTOS. A 1” (25 mm) clearance to combustibles must be maintained around any vertical vent pipe.
Initial Installation QUALIFIED INSTALLERS ONLY Vent Configurations and Restrictor Settings: NOTE: The total length of the vent pipes can not exceed 30 feet (9.17 m). Any combination of rise and run can be used as long as it lays within the shaded area (a total of three (3) 90° elbows or six (6) 45° elbows can be used). In addition to what is shown, if a 90° elbow is used in the horizontal plane, 3 feet (91.
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 ¼ 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.

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 35). 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 37), 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.
