Help with Gazco studio 2

[Alexis]

hi I hope you can help. We have recently had a gazco studio 2 open fronted fire fitted.we also bought the granite inserts. However the flames are not 'straight' - they lean to the back of the fire. This means the granite is being burned and black carbon deposits are being left. What could be causing this? Thanks in advance. A.

You need to urgently get the gas engineer who fitted your fire back, and till then do not use it

Standard on the Gazco fires unfortunately if in doubt contact Gazco on
01392 261950.
The other thing to do is switch the fire on and turn it to low straight away for 10/15mins to allow the granite to heat up slowly stops it cracking
