The variable control valve can be set to any 

heat setting and flame height desired, by sim

ply turning the control knob until that setting 

is attained. Even the lowest setting provides 
realistic,  dancing  yellow  flames.  Selecting 

higher settings produces greater heat output. 
This results in increased heating comfort.
