Non-nominal systems: Hab downstairs wall heater
Notes on non-nominal systems:
At around 18:30pm, the crew upstairs heard a strange sound coming from downstairs (sounded like rushing water). We went downstairs to investigate and smelled gas. We saw that the wall-mounted heater (to the right of the engineering airlock) that the left side of the heating grill was operating normally (glowing red), but the right was not glowing and there was a visible flame behind. Commander Andrew immediately turned the thermostat to the off position as I radioed mission support to advise on the situation. The flame then went out and the rushing sound stopped. We opened the engineering airlock door to vent the gas from the room. No alarms were triggered. The gas heater thermostat is now set to “off” and confirm the pilot light is still burning.
