INNER FIREPLACE COLLAR Figure 11 Figure 12 Step 3. INSTALL THE VENT SYSTEM General Information These instructions should be used as a guideline and do not supersede local codes in any way. Install vent according to local codes, these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards of CAN/CGA-B149.1 and B149.2 in Canada. These fireplaces are designed, tested and listed for operation and installation with, and only with, Secure Vent™ (SV 4.5) Direct Vent System Components, Secure Flex™ Flexible Vent Components manufactured by Security Chimneys International. These approved vent system components are labeled for identification. FIREPLACE SPECIFICATIONS DO NOT use any other manufacturer's vent components with these appliances. These fireplaces must be vented directly to the outside. The vent system may not service multiple appliances, and must never be connected to a flue serving a solid fuel burning appliance. The vent pipe is tested to be run inside an enclosing wall (such as a chase). There is no requirement for inspection openings in the enclosing wall at any of the joints in the vent pipe. Preparing the Appliance Top Vent Outlet in All Venting Applications Using the Appliance Top Vent Outlet A vent restrictor may be needed with this appliance. Install the vent restrictor (provided) in the appliance top flue outlet as shown in Figure 12. It is held in place by friction, only. Select Venting System - Horizontal or Vertical Select Venting System - Horizontal or Vertical VERTICAL TERMINATION SYSTEMS (ROOF) Figures 13, and Figures 23 through 27 on pages 12 to 13 and their associated Vertical Vent Tables illustrate the various vertical venting configurations that are possible for use with these appliances. Secure Vent pipe applications are shown in these figures; Secure Flex pipe may also be used. A Vertical Vent Table summarizes each system’s minimum and maximum vertical and horizontal length values that can be used to design and install the vent components in a variety of applications. Both these vertical vent systems terminate through the roof. The minimum vent height above the roof and/or adjacent walls is specified in ANSI Z223.1-(latest edition) (In Canada, the current CAN-1 B149 installation code) by major building codes. Always consult your local codes for specific requirements. A general guide to follow is the Gas Vent Rule (refer to Figure 4on page 5). Vertical (Straight) Installation Determine the number of straight vent sections required. 4 ..." (114 mm), 10 ..." (267 mm), 22 ..." (572 mm), 34..." (876 mm) and 46..." (1181 mm) net section lengths are available. Plan the vent lengths so that a joint does not occur at the intersection of ceiling or roof joists. Refer to the Vent Section Length Chart.
