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 venting according to local codes, these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards of CAN/CSA-B149.1 in Canada. Ensure clearances are in accordance with local installation codes and the requirements of the gas supplier.
Vertical Termination Systems (Roof) See Figure 19 and Figures 29-33 on Pages 17 and 18 and their associated Vertical Vent Tables which 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.
Vertical (Offset) Installation Analyze the vent routing and determine the quantities of vent sections and number of elbows required. Refer to Vertical Vent Figures and Tables on Pages 17 and 18 to select the type of vertical installation desired. Vent sections are available in net lengths of 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2" (572 mm), 34-1/2 " (876 mm) and 46 1/2" (1181 mm). Refer to the Vent Section Length Chart on Page 13 for an aid in selecting length combinations.

Support the vertical vent run sections -Support the vertical portion of the venting system every 8 feet (2.4m) above the fireplace vent outlet using field provided support straps (conventional plumber's tape). Secure the plumber's tape to the framing members with nails or screws.
J. Install the storm collar - Install the storm collar, supplied with the flashing, over the vent/flashing joint. See Figure 27. Loosen the storm collar screw. Slide collar down until it meets the top of the flashing. Tighten the adjusting screw. Apply non-combustible caulking or mastic around the circumference of the joint to provide a water tight seal.

VERTICAL VENT FIGURES/TABLES Notes: • Secure Vent™ (rigid vent pipe) is shown in the Figures; Secure Flex™ (flexible vent pipe) may also be used. • It is very important that the horizontal/inclined run be maintained in a straight (no dips) and recommended to be in a slightly elevated plane, in a direction away from the fireplace of 1/4" rise per foot (20 mm per meter) which is ideal, though rise per foot run ratios that are smaller are acceptable all the way down to at or near level. • SV4.

J. Assemble vent run to exterior wall - If not previously measured, locate the center of the vent at the exterior wall. Prepare an opening as described in Step B. Assemble the vent system to point where the terminus of the last section is located relative to the exterior surface to which the termination is to be attached as shown in Figure 36 and Table 8 on Page 21. If the terminus of the last section is not within this distance, use the telescopic vent section SV4.5LA, as the last vent section.
See Table 8 as an aid in venting component selection for a particular range of exterior wall thicknesses.

Vertical or Horizontal Venting Using Secure Flex Kits and Components Secure Flex™ venting kits and components may be used in any venting application in place of rigid Secure Vent™ (SV4.5) direct-vent components. All restrictions, clearances and allowances that pertain to the rigid piping apply to the flexible venting. Secure Flex kits may not be modified; also, under no circumstances may separate sections of flex pipe be joined together. APPLY ONLY MIL-PAC BLACK HIGH TEMPERATURE SEALANT (Cat. No.
Step 4. Field Wiring Note: The gas valve is set in place and pre-wired at the factory. CAUTION Ground supply lead must be connected to the wire attached to the green ground screw located on the outlet box. See Figure 47. Failure to do so will result in a potential safety hazard. The appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, the National Electrical Code, ANSI/NFPA 70-latest edition. (In Canada, the current CSA C22-1 Canadian Electrical Code).
Step 5. Connecting Gas Line Gas Flex Line Connector All codes require a shut-off valve mounted in the supply line. The orientation of the shut-off valve should face the front. Figure 48 illustrates two methods for connecting the gas supply. A Sediment Trap is recommended to prevent moisture and debris in gas line from damaging the valve. The flex-line method is acceptable in the U.S.A. where local codes permit, however, Canadian requirements vary depending on locality.
TEST ALL CONNECTIONS FOR GAS LEAKS (FACTORY AND FIELD): WARNING Never use an open flame to check for leaks. Turn on gas supply and test for gas leaks using a gas leak test solution (also referred to as bubble leak solution). Note: Using a soapy water solution is an effective leak test solution but it is not recommended, because the soap residue that is left on the pipes/fittings can result in corrosion over time. A.
Step 7. INSTALL VOLCANIC STONE, GLOWING EMBERS AND LOGS WARNING • DO NOT attempt to install the logs until the appliance installation has been completed, the gas line connected and tested for leaks and the initial burner operation has been checked out. • The size and position of the log set was engineered to give the appliance a safe, reliable and attractive flame pattern.

Step 8. Installing the Glass Door WARNING • Do not attempt to substitute the materials used on these doors, or replace cracked or broken glass. • Handle this glass with extreme care! Glass is susceptible to damage – Do not scratch or handle roughly while reinstalling the glass door frame. • The glass door(s) of this appliance must only be replaced as a complete unit as provided by the manufacturer. Do not attempt to replace broken, cracked or chipped glass separately.
Burner Air Shutter Adjustment Procedure Burner Flame Appearance Model SDV35 WARNINGS • Air shutter adjustment should only be performed by a qualified professional service technician. • Ensure front glass panel are in place and sealed during adjustment. CAUTIONS • Soot will be produced if the air shutter is closed too much. Any damage due to carboning resulting from improperly setting the air shutter is n ot covered under the warranty. • The air shutter door and nearby appliance surfaces are hot.
Step 11. ATTACHING SAFETY-IN-OPERATION WARNINGS It is the installer's responsibility to ensure these warnings are properly affixed during installation. These warning labels are a critical step in informing consumers of safe operation of this appliance.
