Yes, air in the gas line can disrupt the gas supply to the burner, causing it to extinguish and trigger the 117 error. This is more common after gas work has been carried out in the area. A qualified engineer can bleed the gas line to remove the air, but it's crucial to identify the source of the air ingress.
