The Consumer Product Safety Commission (CPSC) has announced
an important safety recall/repair warning on a selected number of
Agio's line of Gas Patio Firepits.
If not attached correctly, the hose from the propane tank
to the gas valve can come into contact with the bottom of the burner
where high temperatures could potentially melt the hose.
