F. Install Mortar
Note: We recommend mortar be applied after facing materials are installed.
Tools Required:
Mortar bag | Drill |
Trowel | 3/32 drill bit (provided) |
Mixing bucket | Phillips screwdriver |
Sponge or spray bottle | Joint striker |
Drill with mixing attachment (optional)
Bucket of water
The mortar material provided should be sufficient to com- plete the installation of the molded brick panels without considerable waste.
NOTICE: Do not substitute for HHT mortar. Other materials may stain the molded brick panels.
•Mix approximately 1/3 of the mortar material with 1/2 gallon of water in the mixing bucket. Stir the mixture with the mixing attachment and drill. The consistency should allow the material to be squeezed from the mortar bag but not too runny.
•Fill the mortar bag with the prepared mixture.
•Apply mortar by squeezing the material from the mortar bag into the joint lines. If filling a vertical line, start from the top and work down. Apply slowly. Mixture should be flush or higher than the panel surface.
•Mix more material as necessary to finish the job and then let the unit set until firm, may take two hours or more.
•Thoroughly clean the bag, tools and mixing bucket.
•Use a joint striker and strike the material in the joints. The excess material should fall off somewhat dry.
•Sweep the loose material off the floor of the unit.
•Final cleanup with sponge and water.
•VERY IMPORTANT: Allow the mortar 72 hours to cure before operating the fireplace.
Mortar should be applied after finishing material is installed. Mortar will be applied between finishing materials and molded brick edges, bottom and sides.
The seam between finishing materials and firebox top must be sealed with
The noncombustible finishing material across the top of fireplace opening will be even with lower edge of metal face.
Noncombustible finishing materials MUST overlap
side faces by 1 1/4 in. (32 mm) to cover the edges of the panels. Finished opening should be 38 x 42 in. (965 x 1067 mm) to allow for door installation.
The surface of the finished hearth extension and the surface of the hearth panel should be level.
