*This project video and walkthrough provided by Keystone Retaining Walls and serves as a general explanation of how to build this project. Measurements and products may slightly vary when using RCP manufactured units. Please contact us if you have any questions.
NOTE: Although this video's focus is on a specific style of fire pit, the information included can be applied to any RCP Block and Brick Fire Pit whether a kit or custom made.
In all situations, fire pit placement and construction must comply with all county, city and local fire department codes and /or regulations for your area; a permit may be required. Always place well away from homes, overhanging trees, power lines or other structures. It is good practice to use a spark screen and never leave a fire unattended. A fire extinguisher or garden hose should be kept nearby. Burn compressed logs or wood with a low resin content, using only 1 or 2 at a time, in a fire pit.
Enjoy the warming glow of your very own wood burning fire pit. The following example focuses on the building of a Country Manor Small Unit Fire pit, but the information can be applied to any custom fire pit or fire pit kit available from RCP Block & Brick.
The finished outside diameter of this fire pit will equal 61" To get started, hammer a spike into the middle of the desired fire pit location. Tie a piece of string to the spike and measure out 46" from the center. Attach another spike at 46". Keeping the string taunt, draw a circle using spray paint or other marking material. This marks the outside diameter of your excavation area.
Excavate the fire pit location 92" x 12" deep around the marked circle. Compact the soil. Place 6". of granular base material within excavated area. Compact and level base to avoid settling.
You can plan on burying up to 1 course of block.
Again using the center spike and string , measure out 20.5 in. for the inside radius. Place the first block with the 4 in. x 6 in. block face touching the end of the string. Continue around the circle using the same technique. Level each block front-to-back and side-to-side making sure that all blocks are level to each other. After placing all 32 blocks, adjust the circle to eliminate any gaps.
Insert Keystone Interlocking pins in center pin hole of the first course of blocks or use masonry adhesive to secure the courses to each other. Then place next course of blocks offsetting the block placement below.
Continue adding courses until your fire pit has reached the desired height.
Finish the fire pit with caps. Align the caps so that you have a ½ in. over-hang on the outside face. Cut the caps at the correct angle to fit tightly together. Once you have all the caps in place, lift one cap at a time and glue the caps to the fire pit using an outdoor concrete adhesive. A fire pit steel ring shield is required to prevent heat damage to the blocks.
OPTIONAL: You can insert a custom metal ring or fire brick to protect the inner walls of your fire pit.
