Codes And Approvals DIRECT VENT: This type is identified by the suffix DV. This appliance draws all of its air for combustion from outside the dwelling, through a specially designed vent pipe system. This appliance has been tested and approved for installations from 0 feet to 4500 feet (1372 m) above sea level. In the USA: The appliance may be installed at higher altitudes.
Specifications WARNING: Operation of this heater when not connected to a properly installed and maintained venting system can result in carbon monoxide (CO) poisoning and possible death.

Initial Installation QUALIFIED INSTALLERS ONLY VENT TERMINATION RESTRICTIONS: N O H D E L B C B B Fixed Closed F G Fixed Openable Closed Openable B A Termination Cap G M J Air Supply Inlet G Gas Meter K I Restriction Zone A (Termination not allowed) Figure 3: Exterior Vent Termination Locations, use in conjunction with Table 1. Table 1: Exterior Vent Termination Locations, use in conjunction with Figure 3.
Initial Installation QUALIFIED INSTALLERS ONLY VENT CONFIGURATIONS: Figures 4 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 VENT PARTS: For horizontal venting installations Sherwood Industries Ltd.’s DV Kit with Coupler (part# EC-061) can be used, refer to “Initial Installation - Freestanding Direct Vent Kit with Coupler.” Table 2: Vent Pipe Types with Part Numbers.
Initial Installation QUALIFIED INSTALLERS ONLY PLANNING YOUR INSTALLATION: When planning your installation, it will be necessary to select the proper length of vent pipe for your particular requirements. It is important to note when passing through a wall, the maximum allowable wall thickness is 10 inches (25.4 cm), 11⁄2 inches (3.8 cm) clearance to combustibles must be maintained. Select the amount of vertical rise desired for “vertical-to-horizontal” type installations.
Initial Installation HORIZONTAL INSTALLATION: QUALIFIED INSTALLERS ONLY STEP 1. Set the appliance in the desired location. Check to determine if wall studs or roof rafters are in the way when the venting system is attached. If this is the case, you may want to adjust the location of the appliance. STEP 2. Direct vent pipe and fittings are designed with special twist-lock connections.
Initial Installation QUALIFIED INSTALLERS ONLY STEP 4. Position the horizontal vent termination in the center of the 10” (25.4 cm) x 10” (25.4 cm) hole, and attach to the exterior wall with the four screws provided. Before attaching the vent termination to the exterior wall, run a bead of non-hardening mastic around the edges, so as to make a seal between the termination and the wall.
Initial Installation QUALIFIED INSTALLERS ONLY CORNER INSTALLATIONS: Do not interfere with the structural integrity of the walls. Outside or Inside Wall Outside Wall Figure 13: Corner installation top vented. VERTICAL INSTALLATION: STEP 1. Check the instructions for required clearances (air spaces) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, or other nearby combustible surfaces. Do not pack air spaces with insulation. STEP 2.
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 STEP 8. Continue to add pipe sections until the height of the vent cap meets the minimum code requirements. Refer to Figure 16 and Table 3. Note that for steep roof pitches, the vent height must be increased. In high wind conditions, nearby trees, adjoining roof lines, steep pitched roofs, and other similar factors can result in poor draft, or down drafting. In these cases, increasing the vent height may solve the problem.
Initial Installation QUALIFIED INSTALLERS ONLY CATHEDRAL CEILING INSTALLATION: STEP 1. Follow installation steps 1 & 2 under ‘Vertical Installation’. STEP 2. Using the plumb bob, mark the centerline of the venting system on the ceiling and drill a small hole through the ceiling and roof at this point. From the roof, locate the drill hole and mark the outline of the “Cathedral Ceiling Support Box”. STEP 3. Remove shingles or other roof coverings as necessary to cut the rectangular hole for the “Support Box”.
Initial Installation QUALIFIED INSTALLERS ONLY INSTALLATION INSTRUCTIONS: 1. Decide on a location for the unit that will meet any or all local code requirements. Refer “Planning Your Installation” and “Clearances to Combustibles”. 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 wall. If obstructions are found in the wall it may be necessary to adjust the location of the appliance. 3.
Initial Installation QUALIFIED INSTALLERS ONLY 19. Place a bead of high temperature silicone on the flue pipe and slide the flex liner over the collar, secure the flex liner with three (3) sheet metal screws evenly spaced. 20. Align all straight sections of pipe, slipping all joints together and installing with three (3) sheet metal screws evenly spaced. 21.
Initial Installation QUALIFIED INSTALLERS ONLY VENTING INTO A CLASS ‘A’ CHIMNEY: This model is also certified and tested to vent into CLASS ‘A’ wood stove chimneys. Place the freestanding direct vent appliance in the desired location. Use a conversion kit from Simpson Duravent (931, 932, or 933), or Security Chimney (SV4CCK1, SV4CCK2, or SV4CCK1). Which kit is used will depending on the inner diameter of the CLASS ‘A’ chimney that this appliance is to be vented into.

Initial Installation REPLACING THE BLOWER: 1. Turn the unit off and remove the log set. 2. Remove the burner tray assembly by removing the screw on either side of the tray, between the front and rear burners. Lift the tray out. 3. Remove the four (4) 5/16” bolts that hold the blower mounting plate to the back firewall. Use a light lubricating oil on screws before removal. 5. Carefully pull the blower assembly into the firebox (see Figure 28).
Initial Installation FUEL CONVERSION: WARNING: This conversion kit shall be installed by a qualified service technician in accordance with the manufacturer’s instructions and all applicable codes and requirements of the authority having jurisdiction. If the information in these instructions is not followed exactly, a fire, explosion or CO poisoning may result. The qualified service agency is responsible for the proper installation of this kit.
Initial Installation GAS LINE CONNECTION AND TESTING: WARNING: Only persons licensed to work with gas piping may make the necessary gas connections to this appliance. GAS LINE CONNECTION • This stove is equipped with a certified flexible pipe located on the right side of the unit terminating in a 3⁄8” male NPT fitting.
Secondary Installation INSTALLATION OF LOG SET AND EMBERS: The placement of the logs is not arbitrary. If they are positioned incorrectly, the flames can be “pinched” and will not burn correctly. The burner come with five (5) locator pins and two (2) resing areas, which make alignment easier. Using the pictures provided, carefully set the logs in place. NOTE: The logs are fragile and should be handled gently. CAUTION: Use only the type of ember material supplied with this appliance.
Secondary Installation 4. Upon the first light up, watch for ignition to ALL burner ports. If a long delay is noted: First, wait for the appliance to cool down. • Open the front door of the appliance. • Check to carefully reposition the embers making sure that burner ports are not plugged solid or blocked. Important note: When the unit is turned on for the first time, It should be turned onto high without the fan on for the first 4 hours.
Operating Instructions FOR YOUR SAFETY READ COMPLETELY BEFORE OPERATING. WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION MAY RESULT CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OR LIFE.
