CAUTION: When using the decorative appliance, the fireplace damper must be set in the fully open position. Gas line for gas log sets used in the Isokern firebox can be FIRE BRICK SIDE routed through the side wall, back wall or floor of the firebox by drilling an appropriately sized hole using a masonry drill bit (Figure 20).
Page 19: Firebrick Installation
NOTE: The 60 & 72 units require 4” Fire-Brick on the side walls. (NO GAPS) Isokern makes no claims as to the performance of fire brick or fire brick mortar(s). It is typical for heat stress cracks to appear in the fire bricks in wood burning fireplaces.

It is the general contractor’s responsibility to assure that listed clearances to combustible framing and to insulation are maintained throughout the construction of the project subsequent to the installation of the Isokern unit.
Page 34: Required Clearances To Insulation And Vapor Barriers
When MAGNUM fireplace installations are surrounded by walls that are to be insulated, the walls must have enough clearance to the Isokern unit in order to maintain the three inch (3”) minimum clearance to insulation. (Figure 75) Never spray the MAGNUM fireplace with any type of sealer, insulation or other material.

DM 54 Chimney Alignment: Where the chimney run is to be a straight vertical run OUTER the DM 54 outer casing block sits directly onto the Isokern CASING smoke dome lid. The DM 54 outer casing block, properly set is intended to be flush with the back face of the firebox smoke dome assembly (Figures 89 and 90 ).

Page 47: Offset Block
DM 54 Offset Chimney Block: For vertical DM 54 chimney to bypass overhead obstructions, 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.
Page 48 DM 54 Chimney System: Offset Block (cont.) With straight chimneys the front of the DM 54 outer casing block sits approximately three and three-quarters inch (3- 3/4”) back from the front of the smoke dome. This allows for a nominal 4” thick wall to be flush with the room side face of smoke dome assembly while the DM 54 chimney passes up the backside of the wall.
Page 49 DM 54 Chimney System: Offset Block (cont.) Offset block Support Foundations: It is required that every third Isokern offset chimney block in the sequence be supported down to footings via concrete block or steel support columns. Plan fireplace and DM 54 chimney systems carefully before foundations are laid to assure that proper footings are available to support Isokern offset blocks chimney run.
Page 50: Offset Block
The total chimney weight above the last offset block will be the total weight of the vertical chimney plus any additional allowable loads such as the Isokern brickledge, its OVERHEAD OBSTRUCTION related brick or stone veneers, and any crown caps, clay pots or other masonry chimney terminations.

Page 56: Common Chimney Terminations
Common Chimney Terminations Two chimney terminations are offered by Isokern, the DM 54 large crown cap and the DM 54 small crown caps. These are cement crown caps designed to provide a weather cap to the DM 54 chimney system. Their design is typical of the cement caps found on traditional masonry chimneys.

Listed chimney liners conforming with the seventeen hundred degree (1700°) Fahrenheit requirements of UL 1777 or ULCS635 or ULC640 may also be used with Isokern fireplaces. Notes: The selected, approved chimney manufacturer must provide the masonry anchor plate designed to fit their flue system.
Page 58: Specialty Applications
Specialty Applications - Two Story Stacked Installations General Information: To install one MAGNUM fireplace and DM 54 chimney system above another, as in a two story stacked installation, both the upper and lower fireplace installations require a concrete slab that is supported down to footings via concrete or steel support structure.
Page 59 “D” is also the sum of “B” plus “C”. “E” is the height of the MAGNUM fireplace chosen for the lower unit and includes the Isokern three inch thick base plate. “E” is seventy inches (69 ½” actual) for all of the MAGNUM models.
