IBC SFC-1 F005 — No flame detected during operation
F005
The appliance was firing and the controller then lost the flame signal during operation. The unit stops rather than continue without a proven flame.
If you smell gas
- Stop what you are doing. Do not use phones, switches, matches or anything that can spark inside.
- Go outside and leave the door open behind you.
- Call the FortisBC 24-hour emergency line at 1-800-663-9911 or dial 911.
Only after that, call ROMA about the boiler. Official guidance: FortisBC gas leaks and odour.

Why a code is not a diagnosis
A flame lost mid-run can be a blocked condensate drain, blocked or recirculating venting, high winds at the terminal, gas pressure dropping at low or high fire, or a fouled ignitor/sensor. The code does not say which.
Safe things to observe
- Note the code and whether high winds or heavy rain coincided with the failure.
- From a safe distance check the vent terminal for blockage or debris.
- If you smell gas or a CO alarm sounds, follow the emergency steps first.
Do not
- Do not keep resetting while the cause is unknown.
- Do not touch gas or ignition components.
How professional service helps
- A technician checks the condensate drain, vent path and termination, gas pressure at low and high fire, and combustion readings.
- The ignitor is cleaned or replaced and the unit is run through full firing to confirm the flame holds.

Parts and service
Parts commonly involved
These parts appear in the documented text for this alert. A code reports a condition, not a failed part — a technician confirms the cause by testing before anything is replaced.
Flame sensor (flame rod)
The flame sensor is the small rod that proves a gas boiler's burner is actually lit before the control will keep the gas valve open.
