Installing Z-shaped Grate

Retainer Bracket

Before grouting the bricks, locate the z-shaped grate retainer brackets on top of the hearth bricks as shown in Figure 22. Position the retainer brackets at 8 3/4" apart from center to center of notch.

Grouting instructions

Material provided:

2 - 9 lb. bags of cement

2 - 9 lb. bags of sand Material required:

1 - Piping bag

1 - Joints striker

1 - Heavy duty mixing bucket

1 - Trowel

1.Moisten brick surface with a damp sponge or a spray bottle just prior to application. When the bricks are wet, any excess grout mixture that might have gotten onto the brick will easily wipe off.

2.In a heavy duty mixing bucket, pour seven (7) cups of water in first, then add in 4.5 lbs. (half of a bag) of sand and 4.5 lbs (half of a bag) of cement. Mix together well using a power drill with a mixing wand attachment.

3.The overall length of piping bag should be about 16". If the bag is longer than 16", cut it down to size by removing end with larger opening. This will make the bag easier to handle.

4.Put 2 to 3 cups of grout mixture into piping bag making sure the smaller opening is downward and over a moist towel to avoid spilling. Place a wet towel over the bucket making sure it is directly on the surface of grout mixture. This will keep the mixture moist and it will not dry out before use.

5.Begin grouting by first doing a “Filler Pass”. This is done by filling the joint about 3/4 full with grout mixture. It is important to work with only 6 bricks at a time so grout doesn't have time to set up before striking.

6.Complete a “Finishing Pass” around 6 bricks you just put filler pass around. This is done by slowly filling in remainder of the joint with a thick amount of grout mixture. Mixture should be a little higher than the brick surface.

7.Using a trowel, remove excess grout mixture by moving trowel in the direction of the joint. Grout mixture in the joint should now be flush with brick surface.

8.Using a Joint Striker, force grout mixture into joint and sweep back and forth until grout is smooth and round. If grout becomes too shal- low, add more grout mixture with piping bag and strike again.

9.Continue procedure around each group of 6 bricks until an entire panel is finished.

10.Using trowel, scrape in direction of joints to remove any grout that may have collected around bricks during striking. If desired, take a moist sponge and lightly sweep over bricks to remove any grout that may have gotten on bricks. DO NO PRESS HARD OR RUB IN A CIRCULAR MOTION. This will press the grout into brick and turn brick a different color.

Allow 72 hours before operating fireplace.
