VENTING INSTRUCTIONS FOR DIRECT VENT FIREPLACES ...

1 1 APPLICATIONT hese INSTRUCTIONS apply to the Simpson Dura-Vent DIRECT Vent System, ModelDV-GS. This VENTING system, in combination with the gas appliance, has been testedand listed as a decorative gas appliance system, or as a DIRECT vent heater systemby a major testing agency such as UL, AGA, CGA, Omni or Warnock the manufacturer's rating plate and instruction manual to confirm that theSimpson Dura-Vent DIRECT vent system is approved for use on the brand nameappliance you have all INSTRUCTIONS carefully before starting the installation. Failure to follow theseinstructions may create a fire or other safety hazard, and will void the warranty. Besure to check the appliance manufacturer's installation INSTRUCTIONS for specificventing and clearance to combustible requirements, which may vary from oneappliance to another.

2 Do not extend the VENTING system vertically orhorizontally in excess of the distance prescribed in the appliancemanufacturer's installation PRECAUTIONSThe Simpson Dura-Vent DIRECT Vent System is an engineered product that has beendesigned and tested for use with an approved list of DIRECT vent FIREPLACES . TheSimpson Dura-Vent warranty will be voided, and serious fire, health, or other safetyhazards may result from any of the following actions: Installation of any damaged DIRECT Vent component. Unauthorized modification of the DIRECT Vent System Installation of any component part not manufactured or approved bySimpson Dura-Vent. Installation other than as instructed by Simpson Dura-Vent and theappliance INSTRUCTIONS FOR DIRECT 1-866-667-84542 Consult your local building codes before beginning the Always maintain required clearances (air spaces) to nearbycombustibles to prevent a fire hazard.

3 Do not fill air spaces with sure to check the appliance manufacturers's installation INSTRUCTIONS for minimumclearance requirements between the outer walls ofthe vent pipe and nearby combustible surfaces. Be sure to check the venttermination clearance requirements from decks, windows, soffits, gas regulators,air supply inlets, and public walkways, as specified in these installationinstructions and local building codes. The fireplace and vent system must be vented directly to theoutside of the building. Each DIRECT vent fireplace must use it's own separate ventsystem. Common vent systems are PRECAUTIONS FOR THE INSTALLER Wear gloves and safety glasses for protection. Exercise extreme caution when using ladders or on roof tops. Be aware of electrical wiring locations in walls and LISTThe Simpson Dura-Vent DIRECT Vent System offers a complete line of componentparts for installation of both horizontal and vertical installations.

4 The galvanized pipeand fittings are used for concealed locations such as attics, or spaces wherecorrosion is a factor, such as above the roofline.

Check the appliancemanufacturer's installation INSTRUCTIONS to confirm what types are permitted, and alsocheck for any VENTING restrictions such as maximum horizontal run, and maximumvertical rise. The two types of installations are: Horizontal Termination (Fig 1 and Fig 2) Vertical Termination (Fig 3)When planning your installation, it will be necessary to select the proper length ofvent pipe for your particular requirements.

6 For horizontal installations, check theappliance manufacturers's installations INSTRUCTIONS to determine the minimumclearance from the rear of the appliance to the wall. It is also important to note thewall thickness. Select the amount of vertical rise desired for "vertical-to-horizontal"type installations. To determine the length of vent pipe required for verticalinstallations, measure the distance from the appliance flue outlet to the ceiling, theceiling thickness, the vertical rise in an attic or second story, and allow for sufficientvent height above the roofline. For two-story applications, firestops are requiredat each floor level. If an offset is needed in the attic, additional pipe and elbows willbe INSTALLATIONStep 1. Set the fireplace in it's desired location.

7 Check to determine if wallstuds or roof rafters are in the way when the VENTING system is attached. If this isthe case, you may want to adjust the location of the 2. DIRECT Vent pipe and fittings are designed with special twist-lockconnections. To connect the VENTING system to the appliance flue outlet, a twist-lockappliance adaptor is required. With some brands of appliances, the Simpson Dura-Vent adaptor will be built into the appliance at the factory. With other brands, itwill be supplied by the appliance manufacturer, for installation in the field. Assemblethe desired combination of pipe and elbows to the appliance adaptor with pipeseams oriented towards the wall or floor, as much out of view as possible. If theappliance adaptor is not built into the appliance at the factory, it may be preferableto assemble the pipe and elbows to the adaptor prior to mounting the adaptor ontothe fireplace.

With the adaptor andpipe attached to the fireplace, slide thefireplace into it's correct location, andmark the wall for a square hole of theappropriate size. Use a 10"x10" squarehole for 7" x 4" pipe and use an 11"x11"square hole for 8" x 5" pipe. The centerof the square hole should line up withthe centerline of the horizontal pipe, as shown in Figure 6.

10 Cut and frame the squarehole in the exterior wall where the vent will be terminated. If the wall beingpenetrated is constructed of noncombustible material, masonry block orconcrete, a hole with zero clearance to the pipe is :(1) The horizontal run of vent must be level, or have a 1/4-inch rise for every1 foot of run towards the termination. Never allow the vent to run downward. Thiscould cause high temperatures and may present the possibility of a fire.(2) The location of the horizontal vent termination on an exterior wall mustmeet all local and national building codes, and must not be easily blocked orobstructed. Termination clearances are as follows:(a) Clearance above the ground, veranda, porch, deck or balcony -12inches minimum.
