Resumen del manual


If a wider CMU block material is used for fireplace wall construction then you must increase the footing to accommodate the change. 2. Table 3 footing depths are adequate for chimney heights up to seventeen feet in standard soil. If the chimney height exceeds seventeen feet or soil pressures are non- standard, increases footing depths at least six inches. Use of reinforced concrete, rebar or steel mesh for stress reduction is recommended. Refer to local building codes. 3. For sandy, loose, or non-standard soil pressures, or for areas that have landfill, Table 3 footing thickness should be increased accordingly. Ensure all local building codes are met. The fireplace furnace foundation must be solid. 4. The CMU foundation wall should end level with the top of the floor joists. Refer to FIGURE 2a. If a floor level installation is planned, then refer to FIGURE 2b, in which case the CMU foundation wall will end below the bottom of the floor joists. 5. Use of a non-combustible H-beam or I-beam may be substituted in the event a combustible header cannot be maintained a minimum distance of 6’8” above a raised hearth. 6. Additional floor protection is not required for installation of the Smart Fireplace Furnace as long as unit is installed per hearth clearances listed in Table 1. FIGURE 2: SINGLE OPENING FIREPLACE SYSTEMS FIGURE 2a shows a fireplace installation where the floor joists are located below the hearth (raised hearth system.) FIGURE 2b shows a fireplace installation where the floor joists are located at the same level as the hearth. Note the changes in hearth depth required for these two different types of installations. FAILURE to observe proper clearances will increase the potential for a fire in the home due to improper installation. STEP 2 – CONCRETE PAD & HEARTH EXTENSIONS .. Determine whether the fireplace is to be installed on an outside wall or an inside wall. The clearances for an inside wall installation differ from an outside wall installation. The type of wall installation will impact the size of the concrete pad and hearth extension to be poured. Ensure conformance to all local building codes. Void areas are often provided in the base to form an air passage for external combustion air (recommended), or an opening for an ash pit or for both. Any nonessential void areas below the hearth should be filled to avoid unwanted air leakage into the furnace. Immediately above the foundation or foundation walls, pouring a concrete pad and creating the required hearth extension will create support for the fireplace furnace and allow an interface to the floor joists. Corbelling may be used to support the hearth extension, but a poured concrete slab, that also supports the fireplace furnace, usually is used to create a hearth extension. Forming the concrete pad requires “block outs” for external combustion air dampers (recommended.) Forming the concrete pad requires an interface with the ash dump provided in the Smart Fireplace Furnace. The concrete pad ash dump block out should be larger than the opening provided for the ash dump in the bottom of the fireplace furnace floor. If a Smart Fireplace Furnace is to be ducted down to a lower level, then include block outs in the concrete pad for the hot air ducting. Refer to FIGURE 3 for a typical outside wall fireplace furnace installation and refer to FIGURE 4 for a typical inside wall fireplace furnace installation. Note that both drawings include block outs for down duct capability. FIGURE 3: OUTSIDE WALL PAD INSTALLATION Use of non-combustible forms will be required for the concrete pad since removal of these forms will not be possible once the concrete pour is complete. Corrugated galvanized sheet metal can be used for the concrete pad form to eliminate any future fire hazard. NOTE: ALL combustible forms used in the hearth extension and concrete pad must not be left in place once the concrete pour is complete. The concrete pad must be a minimum of eight inches thick and be capable of resisting thermal stresses resulting from high temperatures. Check local building codes and specific requirements in order to define the proper thickness requirement of the concrete pad and hearth extension for your specific fireplace furnace application. Hearth extensions must be constructed of noncombustible materials. A U.L. listed hearth extension may be used or the hearth extension can be a continuation of the poured concrete pad. Refer to FIGURE 2 for the depth requirements of a hearth extension. Hearth extension requirements vary according to where the floor joists meet the hearth and what local code requires. FIGURE 4: INSIDE WALL PAD INSTALLATION NOTES: 1. If installing a fireplace furnace on an inside wall, refer to FIGURE 4. An inside wall concrete pad must be six inches deeper than FIGURE 3 shows to allow for additional air space required for inside wall installation. 2. Overall concrete pad and hearth extension sizes can be determined by referring to FIGURE 3. Rem...
