Direct-Vent is sealed combustion and draws combustion air from the outdoors. 4. 4. _________ BTU/Hr (max. the space can support) _________ BTU/Hr (actual amount of BTU/Hr used) Example: 61,440 BTU/Hr (max. the space can support) 71,000 BTU/Hr (actual amount of BTU/Hr used) The space in the above example is a confined space because the actual BTU/Hr used is more than the maximum BTU/Hr the space can support. You must provide additional fresh air. Your options are: a. Rework equations adding the space of adjoining room(s). If the extra volume provides an unconfined space, then remove door or add ventilation grills between rooms. Refer to National Fuel Gas Code, ANSI Z223.1, Section 5.3. b. Vent room directly to the outdoors. Refer to National Fuel Gas Code, ANSI Z223.1, Section 5.3. c. Install a lower BTU/Hr appliance, such as a 24,000 BTU/Hr, to make the area an unconfined space. If the actual BTU/Hr used is less than the maximum BTU/Hr the space can support, then the space is an unconfined space. You will need no additional fresh air ventilation for an unconfined space. WARNING: IF THE AREA IN WHICH THE APPLIANCE MAY BE OPERATED IS SMALLER THAN THAT DEFINED AS AN UNCONFINED SPACE, PROVIDE ADEQUATE COMBUSTION AND VENTILATION AIR BY ONE OF THE METHODS DESCRIBED IN THE NATIONAL FUEL GAS CODE, ANSI Z223.1, SECTION 5.3 OR APPLICABLE LOCAL CODES. PREINSTALLATION WARNING: BEFORE INSTALLING IN A SOLID FUEL BURNING FIREPLACE, THE CHIMNEY FLUE AND FIREBOX MUST BE CLEANED OF SOOT, CREOSOTE, ASHES AND LOOSE PAINT BY A QUALIFIED CHIMNEY CLEANER. CAUTION: APPLIANCES CREATE WARM AIR CURRENTS. THESE CURRENTS MOVE HEAT TO WALL SURFACES NEXT TO APPLIANCE. INSTALLING APPLIANCE NEXT TO VINYL OR CLOTH WALL COVERINGS OR OPERATING APPLIANCE WHERE IMPURITIES IN THE AIR (SUCH AS TOBACCO SMOKE) EXISTS, MAY DISCOLOR WALLS. Note:Illustrations shown in this manual reflect “typical” installations with nominal dimensions and are for reference only. Actual installations may vary due to individual design preferences. However, always maintain minimum clearances to combustible materials and do not violate any specific installation requirements. Refer to Figures 1 through 7 for clearances. Note:The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence. • Turn off gas supply to the fireplace or firebox. • Position appliance in fireplace or firebox. • Connect gas line. • Secure appliance. • Operate the appliance and check operation. Check Gas Type This appliance can only be connected to the gas type specified on the appliance rating plate. This appliance can not be modified in the field for a different gas type. If the gas supply differs, DO NOT INSTALL the appliance. Contact your dealer to obtain the correct appliance. CLEARANCES WARNING: DO NOT INSTALL THIS GAS APPLIANCE: • IN SLEEPING QUARTERS, BATHROOMS, A MOBILE HOME, OR A RECREATIONAL VEHICLE. • WHERE CURTAINS, FURNITURE, CLOTHING OR OTHER FLAMMABLE OBJECTS ARE LESS THAN 42" FROM THE FRONT OF THE GAS APPLIANCE. • IN HIGH TRAFFIC AREAS. • IN WINDY OR DRAFTY AREAS. VENT FREE APPLICATIONS Ensure the minimum clearances shown in Figures 1 through 7are maintained. Left and right clearances are determined when facing the front of the appliance. NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE. Follow these instructions carefully to ensure safe installation. Failure to follow these requirements may create a fire hazard. Step 1. Sidewall Clearances: The sides of the fireplace opening must be at least 16" from any combustible side wall (Figure 1). 16" Min. 42" Min. Figure 1 Step 2. Ceiling Clearance: The ceiling must be at least 42" from the top of the appliance opening (Figure 1). Step 3. Noncombustible materials (minimum requirements): To install the appliance without wood mantels, shelves or other combustible projections directly above the opening of the fireplace (firebox) refer to Figure 2 and Table 2.Note that at least 8" of noncombustible material must be installed above the appliances described in this manual. Noncombustible materials, such as slate and marble, must be at least ..." thick.
