Inspect hose before each use. If there are signs of abrasion, wear, cuts, or leaks, the hose must be
replaced. DO NOT USE.
Inspect burner before each use. Check burner and burner venturi tube for insects and insect nests.
A clogged tube can lead to a re beneath unit.
Check to ensure the orice is centered inside the venturi tube. Failure to properly assemble the
valve orice to the venture tube can result in gas leak or potential re at connection. See assembly
steps for proper assembly method.
