The mortar is supplied dry, in 50 pound 19 pails. Earthcore mortar is mixed with clean water to a ' smooth, workable texture (without lumps or dry pockets) ► 1 of a "toothpaste" consistency. This mixture is suitable for ' , application onto Isokern components by using a masonry grout II- bag supplied with the unit. I' / Attention should be paid that the mortar mixture is not 41 too thin or runny, as this will not allow the mortar to reach its maximum bonding strength. 11117 Earthcore mortar is squeezed from a grout bag onto the contact surfaces of the Isokern components as they are fitted together. It is important that a 1/2" bead of mortar on all the components' contact surfaces is applied at about 1/2" in from all edges of the contact surface of the component.(Figure 8) When setting the next component onto the mortared FIGURE 7 contact surface of the first component, some mortar should squeeze out along the face of the entire joint as a sign of ECI complete and proper sealing of the joint. MORTAR On broader contact surfaces it is advisable to apply several additional 1/2"beads of the Earthcore Mortar to the area Alto assure proper sealing of the joint. r Properly mortared firebox and smoke dome assembly ",„„i0-- requires approximately 30 pounds (dry measure) of Earthcore i-- — ' mortar. Broken Components: Components broken into 2 or 3 pieces can be repaired by using Earthcore mortar along the break line as the component is set into place. Components broken into multiple small pieces FIGURE 8 should be discarded and replaced. Leveling and Aligning Components: Be sure to assemble all Isokern components level and flush with adjoining components. Earthcore mortar is not intended to create a mortar joint of any thickness for leveling purposes.Therefore,leveling and alignment adjustments are made by the use of small plastic shims supplied with the unit.(Figure 9) The shims can be inserted under a component to level 1 .4. 4,11/N,.. ,. _. • SHIM IF REQUIRED TO and align it with adjacent Isokern components.

It is composed of two precast, mating components, \.p the outer casing block and an inner liner. arN General Information: This chimney system is designed for installation in accordance ` %. with the National Fire Protection Standard for Chimneys and Solid Fuel-Burning Appliances, NFPA 211 and in accordance with codes ,` 4 such as ICC, BOCA Basic/National Codes, the standard Mechanical • �!` `_ Code and the Uniform BuildingCode. i Note: Illustrations shown reflect"typical"installations with nominal , 'Ipr dimensions and are for design and framing reference only. Alwaysmaintain minimum required clearances to combustible materials anddo not violate any specific installation requirements.Required DM Chimney Clearance:The DM chimney system,rated UL 103HT,is listed for zeroclearance to normal construction materials. 4 The DM chimney system may be enclosed in a wood chimney chase at zero clearance to wood framing members.WARNING: Keep all insulation minimum of three inches (3")away from all DM chimney components. If insulation is used inwalls surrounding the chimney, insulation may be installed behind sheathing of gypsom board,plywood,particle board or other materialon the side facing the Isokern material.The facing material cannot be within 1 1/2"to the chimney outer casing.Failure to use manufacture's provided parts or variations in techniques and construction materialsipi1P. or practices other than those described in this manual may create a fire hazard and void the limited warranty.Note: A firestop is required wherever a chimney passes between one zone of a building to another. Ex: When the chimney passes through the ceiling into the attic area, there must be a sealed area around the chimney so there isn't a chaseway for a fire to get to the attic. When lateral support is required for DM chimneys, the framing members will be in contact with the DM chimney system. \/ Important: "Combustibles" are defined as "normal construction I \/ materials"and are considered to be:framing materials,particle board, mill board, drywall, plywood paneling, plywood sub flooring, and 1 wood flooring. ' I► Mechanical Vent Systems: ' f I�\I It is acceptable to use mechanical draft systems, if the venting P Y companies do the engineering calculations and make the necessary recommendations for fan size and flue vent diameter following I/ ' the guidelines of NFPA 211/2006, pg. 211-13.

OUTER CASIN OFFSET BLOCK RECEIVED 06/05/2018 31 ASPEN BUILDING DEPARTMENT DM Chimney System: Installation Instructions DM Chimney Alignment: OOWhere the chimney run is to be a straight vertical run the DM outer casing block sits directly onto the Isokern smoke �o0 dome lid.The DM outer casing block,properly set is intended to be flush with the back face of the firebox smoke dome OUTER CASING assembly (Figures 48 and 49). FIGURE 45 Set in this way the DM outer casing block will sit three and three fourths inches(3-3/4")back from the front face ri of the smoke dome. (Figure 48). 12" HIGH This total set-back distance makes it possible for INNER LINER a three and one-half inches (3-1/2") thick bearing header to pass over the firebox smoke dome assembly and for the DM FIGURE 46 chimney to run straight up the back side of the bearing header (Figure 49). 6"HIGH STARTER q■/ INNER LINER Installation of the DM chimney: Begin straight DM chimney runs by setting a DM FIGURE 47 10 3/4" ' outer casing block in a bed of mortar on top of the smoke dome lid with the outer casing block centered on the lid from side to 4f■c,--., /\ side and flush with the back of the smoke dome lid. 3 3/4" o� Be sure that the outer casing block aligns with the flue ir 1ihole in the smoke dome lid. Next set the DM inner liner's six inch(6")tall starter piece (Figure 47) inside the first outer casing block. The "factory" version of the six inch (6") tall inner liner starter \ , piece has a female end and a flat end.Set this inner liner starter with the flat end down. Set the downward end into Earthcore FIGURE 48 , Mortar so that it is fully sealed to the smoke dome lid. WARNING: Do not mortar the air space between the inner 00 liners and the outer casing blocks. Starting with the six inch (6") tall inner liner starter I \�� piece creates six inch(6")staggered horizontal joints between the inner liner and the outer casing block. / Both the outer casing block and the inner liner components have tongue and groove type detailing on each ` r end to assure alignment and interlock of the pieces as they are liI' \/ stacked and glued together. I_ ` A Notes: If the "factory" inner liner starter piece is broken or otherwise unavailable then a full twelve inch(12") tall inner 11111 liner piece can be cut to six inches (6") in height to make an inner liner starter piece. DM chimney inner liners can be stacked with either the male or the female end up. In either case start the inner liner stack with a six inch(6")starter piece. Magnum Fireplace Shown For Illustration Purposes Only After setting the DM inner liner starter piece, apply FIGURE 49 mortar to the top of the starter liner. Continue the straight chimney run by placing a full height inner 1' t,i� I) inch (6") starter liner. The top of this full h will sit 6" above the top of the outer casing b oc that was previously set. 0 6/0 5/2 018 32 ASPEN BUILDING DEPARTMENT DM Chimney System: Lateral Support This six inch (6") offset between joints of the inner liner stack and the joints of the outer casing stack continues to the top of the chimney run. Continue the straight vertical DM chimney by setting an outer casing block onto the mortared top surface of the preceding outer casing. The grooves on the bottom end of the upper outer casing block fit onto the tongues on the top of the lower outer casing block.This assures proper alignment of the / two components. Next place a full height inner liner onto the mortared ( top end of the previously set inner liner. Proceed this alternate stacking of outer casing blocks and inner liners until the desired height of the flue is attained. Mortar all outer casing blocks together and mortar all inner liners together.Do not mortar or fill the space between the outer casing and the inner liner. Lateral Support for DM Chimneys: Though not required, it is recommended that where the DM chimney is built up along an exterior wall the vertical chimney system can be connected to the structural wall system at a minimum of four foot (4') intervals. This connection can be made using 18 gauge strap ties(Simpson Strong Tie CS coil strap,or equivalent). Starting on one side of the DM chimney, at four foot S � \ (4') intervals up the structural wall adjoining the chimney, (� connect one 18 gauage strap tie to the structural wall with C ; two, three inch (3") #8 (minimum) wood screws or masonry anchors,as appropriate. Next fold the strap around the three exposed sides of the outer casing. Connect the strap to each of the three outer casing faces with two, one and one-half inch (1-1/2") long masonry anchors, such as "Tapcon"or"Titen" screws. Fasten FIGURE 50 the strap back to the structural wall with two three inch(3") #8(minimum)wood screws or masonry screws,as appropriate. (Figure 50) Where DM chimneys are built up from the interior walls the DM chimney outer casing block is to be laterally braced at ceiling and roof penetrations. _ Pressure treated two inch (2") by four inch (4") 0ii;1:1 blocks,set at each side of the flue between the trusses or rafters and fastened to the pre-engineered roof trusses or rafters with two 16d common nails at each end, provides lateral support, ��'-- _0 parallel with the framing.Additionally,a two inch(2")by four -- inch (4") by six feet (6') minimum pressure treated member -`,, \- ("rat run")installed on each side of and butted up to the outer u' casing block will provide lateral support perpendicular to the direction of the truss or rafter framing system. Fasten the perpendicular member with two 16d common nails to each intersecting truss or rafter. The perpendicular bracing should be installed on the top side the ceiling level framing as well as on the bottom side of the rafters. (Figure 51) Note: A firestop is required wherever a chimney passes between q0 one zone of a building to another.Ex:When the chimney passes through the ceiling into the attic area, there must be a sealed RECEIVED area around the chimney so there isn't a chaseway for a fire to get to the attic. FIGURE 51 06/05/2018 33 ASPEN BUILDING DEPARTMENT DM Chimney System: Offset Block DM Offset Chimney Block: For vertical DM chimney to bypass overhead obstructions, 7 the Isokern offset chimney block is used. Offset blocks are six inch (6")thick,single module chimney components,measuring twenty-one and one-half inch(21-1/2")wide by twenty-five inches(25")long.The fourteen inch hole passes through the block at thirty(30°)degrees.An offset chimney block can be set as the first flue component on top of o o the fireplace smoke dome. When building offset sequences it is necessary to support FIGURE 52 o0 the third offset block in the sequence and every third offset block thereafter. When using only one or two offset blocks no additional 4 support is required. 4 Offset sequences are best when built as low as possible in the 4A 1 chimney run to maximize performance.Do not make support columns of brick, stone or wood.All support columns must bear onto proper 41 r noncombustible foundations. Isokern Offset Chimney Block Installation: 11 r1 1 Isokern offset chimney blocks are stacked in a stair step fashion with each successive block overhanging the previous offset 11 block by three inches(3"),allowing the flue to rise at an angle of thirty 11 I (30°)degrees off of vertical.(Figure 52) ( ) When building offset sequences check the interior flue alignment as each offset block is set to avoid creating overhanging jil ledges on the inside of the flue. Such internal overhangs will inhibit j flue drafting. Each offset block is to be set fully in a bed of Earthcore Mortar, 440V completely sealing each offset block to the underlying component. Offset chimney block sequences can be built to shift the chimney run to the left,right or to the rear of the firebox/smoke dome assembly. Offset blocks can also be set in a spiraling rotation, thus FIGURE 53 moving the chimney to a point that is diagonally away from its starting point. Offset blocks require a 1 1/2" clearance to combustible framing. Offsets to the Left or Right: // A When offsetting chimneys to the left or right of the firebox it is not possible to build a support column directly under the third offset block. To create proper support, construct a support column against the firebox from bearing up to the level of the smoke dome. Bridge from the column over to bearing on the smoke dome with two pieces of four inch (4") by four inch (4") by five-eighths inch (5/8") steel angle. On the steel angles build a masonry or steel support column up to the underside of the third offset block in the sequence.(Figure 53) Note: For offset chimney block sequences that clear the side wall of the firebox below,it is allowable to support the first offset block that clears the the firebox side wall and the psi i n .

FIGURE 59 The brick ledge has four 2-1/2" holes through it that align with the hole in each of the four corners of the DM outer casing block. These four holes are provided for reinforcement of the chimney stack by the insertion of#4, minimum, steel reinforcing rods and subsequent grouting.(Figure 60&61) �N' <2�7 The brick ledge is intended for use in chimneys that 3 rise through the roof only where all four sides of the chimney O are bounded by the roof.

RECEIV r 06/05/2 18 37 ASPEN BUILDING DEPARTMENT DM Chimney System: Brick Ledge Load Capacity Lateral Support for Isokern Brick ledge Chimneys: Once the DM chimney and brick ledge are assembled and after the intended masonry veneer has been installed on the brick ledge,be sure to brace the chimney following the guidelines -on page 32 of this manual for Lateral Support of DM chimneys. Load Capacity for Brick Ledge: The sources of load delivered into the Isokern brick ledge are: (1) the total physical load of brick, stone or other masonry veneer on the brick ledge,and (2) loading due to the force of wind delivered against the exposed height of the chimney mass. The required height of any chimney is governed by _`�;,. �---- applicable local building codes. The overall finished height of any chimney varies based upon site-specific conditions (eg. elevation of roof line, roof pitch, distance of the chimney from @, the ridge,etc.). ISOKERN It is relatively simple to calculate the total physical load BRICK LEDGE on the brick ledge resulting from the physical weight of applied s veneers built to code height,however calculation values for load to the brick ledge due to wind are site specific and based on local variables such as wind speed zone,exposure classification, _ S eave height and roof pitch of the structure, as well as height of chimney mass exposed to wind. The total of physical load and load due to wind must not exceed ninety four hundred(9400)pounds.

A typical flashing detail would be to field fabricate an I aluminum or galvanized sheet metal flashing, approximately thirty-two inches(32")square with a twenty inch(20")square hole INNER in it,to serve as an inner flashing. (Figure 63) FLASHING Place the inner flashing on the first DM outer casing block that fully clears the roof line.Keep the flashing to about a one-half FIGURE 63 inch(1/2") lap onto the top of the outer casing block. The twenty inch (20") square hole in the flashing should fit to the outside of the alignment grooves on top of the DM outer casing.Continue the 1L2 DM chimney up to the required termination height. Once the masonry veneer is in progress the inner flashing iis set into a horizontal joint in the veneer at a level above all other roof deck flashings, chimney-to-roof flashings and counter IIIII ill flashings. Weep holes should open to the outer face of the veneer at vertical mortar joints located at the level of the inner flashing. (Figure 64) !� Where moisture may develop between the DM outer casing and the chimney veneer,inner flashings as described above will help to divert such moisture to exterior face of the veneer ��� by way of the weep holes and thereby keep such moisture from working its way down between the veneer acing and the DM outer �A casing and into the interior of the structure below. IIII M DM Small Crown Cap(Figure 65) The DM small crown cap is a prefabricated cement _ weather cap that measures 26- 1/2"square and 3"thick.The small � crown cap is designed and installed the same as the large crown 111 cap. The small crown cap is intended for use where DM chimneys are to receive thin veneers and cultured stone that do FIGURE 64 not require the installation of the Isokern brick ledge. The small crown cap is also suitable where DM chimneys are to receive ' � ` a stucco finish. Other chimney terminations are possible with DM chimneys. Check local codes for use of custom chimney terminations and decorative shrouds. SMALL DM Large Crown Cap(Figure 66) CROWN CAP The DM large crown cap is a prefabricated cement FIGURE 65 weather cap for masonry veneer chimneys. The large crown cap measures 37-1/2"square and is 3"thick at its center. The component has an octagonal hole at its center so that the top inner liner of the DM chimney stack can pass through it. The crown cap then sits on the top most DM outer casing block. To set the large crown cap the last inner liner should be at least 3"above the last outer casing block in the chimney stack.

The top of the chimney must be at least 2'above this work point. (Figure 68) (3)In all cases,the chimney cannot be less than 3'above the roof at the edge of the chimney. (Figure 67&68) 10'-0" A simple example of this would be if the roof is flat then the chimney would need to be at least 3' above the roof surface. Or, if the chimney penetrates the roof at the ridge then the chimney must be at least 3'above the ridge.(Figure 69) WORK POINT N z Note: The "2 foot in 10 foot rule" is necessary in the interest NIMN of fire safety but does not ensure smoke-free operation of the fireplace.

Installation of the FTF-13 Metal Chimney System for the Isokern Fire-Lite: (•I Transition from the Isokern to the FTF-13 Metal Chimney System: The FTF-13 metal flue attaches to the smoke dome's top plate by use of the AP-ISO masonry anchor plate. The Anchor Plate is fitted with an octagonal base plate to affix it to the smoke dome's top plate. The anchor plate also has starter rings for both the inner and the outer sleeves of the metal flue(Figure 89). Step 1. Lay a twenty-four inch (24") square, half inch (1/2") thick(minimum)piece of ceramic fiber high temperature blanket ("Inswool" Ceramic Fiber HP Blanket, rated for temperatures up to 2400 degrees F., or equal.) on the top of the top plate. Cut a hole approximately 11" in diameter in the center of the high FIGURE 88 temperature blanket and align the blanket on the flue hole in the top plate(Figure 89). ECO-STEEL Step 2.Fit the AP-ISO Anchor Plate assembly onto the Inswool so (•I or FTF-13 that the inner flue sleeve projecting out the bottom of the anchor plate is inserted through the high temperature blanket and into the Anchor Plate hole in the top plate.The high temperature blanket is held between the anchor plate and the top plate as a gasket(Figure 89).Attach `� 1 Anchor Plate to the top plate with masonry attachment screws Inswool through holes provided in the anchor plate into the top plate. Do Blanket not over torque masonry screws into the Isokern material.(Figure 90) Chimney Terminations: FTF-13 chimney pipe requires a termination component to be installed at or near the top of the chimney chase flashing.
