WARNING
Burn Hazard
■ Before lighting, ensure the variable heat valve

output setting. See Fig. 7.
■ Failure to do so will result in the main burner
igniting at full heat output.
■ Serious injury or death due to burns may
occur.

(This prevents lockup of the excess fl ow check valve
internal to the regulator's POL fi tting.)
2. Fully depress the button on the safety control valve
while pushing the igniter button. The burner will light.
See Fig. 7.
