Brrrr - getting Chilly - CARVER SD2000

[RAW]

Good Evening,
Have one of these in New Old Van
Carver SD2000
It is lit and we think on full but really not putting out much heat
Any ideas welcomed as getting cold out and in (near the sea!!)

you might be on pilot /low ,take the front off and find the little glass window to see how much flame there is
