STEP 1: Run the utilities. Protect the propane line with a sleeve so it doesn’t get damaged during the construction.
The propane feature should be pressure tested and installed by a licensed bonded gas technician.
STEP 2: Compact the aggregate base to its optimum density. The density can be measured with a dynamic cone penetrometer.
If we were working off pavement, a wrought iron drain would be needed to allow proper drainage as it is heat resistant, if it were installed within the fire pit.
In this application, we can drain down through the aggregates.
STEP 3: Position the insert and use it as a guide to highlight the perimeter where the walls of the fire pit will be constructed.
Trick of the trade: To avoid leaving stains of paint on the insert, pour marking chalk around it. The perimeter can be painted once the insert is removed.
STEP 4: Make sure the base or setting bed is levelled.

STEP 5: Start laying the wall blocks.
