Operation of improperly installed and maintained venting system could result in serious injury, property damage or loss of life. NOTICE WARNING VENT INSTALLATION Failure to follow these instructions will void the warranty. INSTALLATION PRECAUTIONS Consult local building codes before beginning the installation.
VENT INSTALLATION INSTALLATION PLANNING There are two basic types of direct-vent installation: • Horizontal Termination • Vertical Termination It is important to select the proper length of vent pipe for the type of termination you choose. It is also important to note the wall thickness. Select the amount of vertical rise desired. The horizontal run of venting must have 1/4" rise for every 12" of run towards the termination. You may use up to three 90° elbows in this vent configuration.

VENT INSTALLATION 1. Determine the route your horizontal venting will take. Note: The location of the horizontal vent termination on the exterior wall must meet all local and national building codes. Snorkel terminations are available for terminations requiring a vertical rise on the exterior of the building. See Figures 12 and 13. Follow the same installation procedures used for standard horizontal terminations.
VENT INSTALLATION HORIZONTAL VENT INSTALLATION (continued) 3. Attach vent pipe assembly to the stove. Set stove in front of its permanent location to insure minimum clearances. Mark the wall for a 91/2" (241) square hole (for noncombustible material such as masonry block or concrete, a 71/2" [190mm] diameter hole is acceptable). See Figure 15. The center of the hole should line up with the center line of the horizontal rigid vent pipe.
VENT INSTALLATION HORIZONTAL VENT INSTALLATION (continued) Interior Wall Surface 5. Slide the wall thimble over the vent pipe before connecting the horizontal run to the vent cap. See Figure 18. 6. Carefully move the stove with vent assembly attached toward the wall and insert the vent pipe into the horizontal termination. The pipe overlap should be a minimum of 11/4" (mm). Apply silicone to the outer pipe connection. Fasten all vent connections with screws provided. 7.

VENT INSTALLATION INSTALLATION FOR VERTICAL TERMINATION 1. Determine the route your vertical venting will take. If ceiling joist, roof rafters or other framing will obstruct the venting system, consider an offset. See Figure 22 to avoid cutting load bearing members. NOTE: Pay special attention to these installation instructions for required clearances (air space) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, etc. Do not pack air spaces with insulation.
VENT INSTALLATION 4. Connect a section of pipe and extend up through the hole. NOTE: If an offset is needed to avoid obstructions, you must support the vent pipe every three (3) feet. Use wall straps for this purpose. See Figure 22, page 20. Whenever possible, use 45° elbows instead of 90° elbows. The 45° elbow offers less restriction to the flow of the flue gases and intake air. 5. Place the flashing over the pipe section(s) extending through the roof.
VENT INSTALLATION VERTICAL TERMINATION CONFIGURATIONS Figures 27 through 30 on pages 22 and 23 show four different configurations for vertical termination. IMPORTANT: Install restrictor as indicated on chart (Figure 11) on page 15. NOTE: Install restrictor into 4" collar of stove or first vent section as shown.

STOVE INSTALLATION CHECK GAS TYPE Use proper gas type for the burner system you are installing. If you have conflicting gas type, do not install burner system. See dealer where you purchased the stove and burner system for proper burner system according to your gas type. CAUTION WARNING INSTALLING GAS PIPING TO STOVE / BURNER SYSTEM LOCATION A qualified installer or service person must connect appliance to gas supply. Follow all local codes.
Only persons licensed to work with gas piping may make the necessary gas connections to this appliance. CAUTION WARNING STOVE INSTALLATION A manual shutoff valve must be installed upstream of the appliance. Union tee and plugged 1/8" NPT pressure tapping point should be installed upstream of the appliance. See Figure 32. NOTE : The gas line connection may be made using 1/2" rigid tubing or an approved flex connector.
CHECKING GAS PRESSURE Check gas type. The gas supply must be the same as stated on the appliance’s rating decal. If the gas supply is different from the fireplace, STOP! Do not install the appliance. Contact your dealer immediately. 2. To ease installation, a 30" (mm) flex line with manual shut-off valve has been provided with on this appliance. Install and attach 1/2" gas line onto shut-off valve. 3.
ELECTRICAL INSTALLATION ELECTRICAL WIRING This stove will work without any electrical supply. Electricity is only needed if you install a remote wall mounted switch. WARNING Electrical connections should only be performed by a qualified, licensed electrician. Main power must be off when connecting to main electrical power supply or performing service. All wiring shall be in compliance with all local, city, and state codes.
LOG PLACEMENT AND ROCK WOOL PLACEMENT WARNING Before you begin — This unit is supplied with ceramic fiber logs. Do not handle these logs with your bare hands. Always wear gloves to prevent skin irritation from ceramic fibers. After handling the logs, wash your hands gently with soap and water to remove any traces of fibers. The positioning of the logs is critical to the safe and clean operation of this heater.
LOG PLACEMENT AND ROCK WOOL PLACEMENT INSTALLING CSDV30 LOGS IN FIREBOX (See Figure 37) 1. Carefully remove logs from wrapping. 2. Open front door of firebox. 3.

OPERATING INSTRUCTIONS WARNING FOR YOUR SAFETY READ BEFORE LIGHTING If you do not follow these instruction exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance is equipped with an pilot which must be lit by hand while following these instructions exactly. B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
OPERATING INSTRUCTIONS T LIGHTING PILOT FOR THE FIRST TIME WARNING INITIAL LIGHTING Purge air from the supply line as follows: • Unscrew main pressure test point. • Leave inlet test screw open until gas comes in. • When gas is flowing, tighten inlet screw immediately.
OPERATING INSTRUCTIONS T LIGHTING BURNER MAIN BURNER SWITCH The “ON/OFF” switch for the main burner can be found on the back right side of the stove. This switch allows you to turn on and to turn off the main burner without using the gas valve knob. Make sure the button is in the “ON” position to light the main burner. See Figure 42. ON F OF Figure 42 - Burner Switch LIGHTING THE BURNER Depress and turn the knob counterclockwise to the “ON” position. See Figure 43.
CLEANING AND MAINTENANCE VENTING SYSTEM A qualified agency should examine the venting system annually. CLEANING GLASS CAUTION Make sure the gas valve knob is in the “OFF” position. Wait at least five (5) minutes before start ing maintenance. Let glass cool before cleaning. Do not clean glass when it is hot. Damage could occur. Clean the ceramic glass periodically. Condensation will sometimes form on the glass during a cold startup. This is normal for all gas fireplaces and stoves.
AIR SHUTTER ADJUSTMENT (NATURAL GAS ONLY) ADJUSTING THE AIR SHUTTER The venturi of the burner is equipped with an air shutter. The opening of the venturi has been set at 1/4" for Natural Gas and fully open for Propane installation at sea level. Natural Gas Models may be adjusted for high altitude as follows: • To increase air mixture, pull down the adjustment rod located beneath the stove. This opens the shutter more and will stop sooting. See Figure 49.
Always use gloves when handling broken glass. WARNING CAUTION GLASS REPLACEMENT Make sure the glass panel edges do not touch any metal parts during thermal expansion. 1. Put on gloves. 2. Remove door from stove. See Page 11. 3. Remove glass from stove by releasing two clamps on bottom of stove. Lift glass frame up and off the unit. See Figure 51. 4. Carefully remove broken glass. 5. Wrap new glass pane with tadpole gasket. Make sure you have 1/4" overlap on each side. 6. Place new glass in frame. 7.
