I had a Valor Black Beauty (Model 349) installed last winter. I noticed then that the heat output wasn’t all that great but left things as they were. This year I notice the room temperature barely exceeds 19°C and am concerned that something has not been done according to the installation manual. The previous gas fire gave a good heat even though the efficiency was only about 50%.
The screw within the restrictor elbow is fully open.
Parameters of the fire are:
Max output heat 4Kw
Min output heat 1Kw
Efficiency 74% (gross)
Can someone please help.
