Gas Fires Need Annual Attention — Here's Why
Gas fires are statistically the highest-risk gas appliance type in UK homes. Many are old, many are open-flue (drawing combustion air from the room), and many haven't been serviced in years. An annual service catches dangerous faults — particularly carbon monoxide problems — before they become incidents.
A full service covers the burner, ignition, flame supervision device, thermocouple, seals, flue draught, ventilation provision and combustion analysis. We service inset (within a fireplace), outset (on a hearth), and modern flueless catalytic fires.
We also repair faults on the same visit where possible — failed thermocouples, failed flame supervision devices, blocked injectors, perished seals and ignition problems are all common, all repairable, and all in stock as common parts.
Real Work Examples
Why Old Gas Fires Are a Particular Risk
Gas fires fitted in the 1980s and 1990s are still in service in many homes. Their burners and combustion characteristics drift over decades; their seals perish; their flue arrangements may not meet current standards. Most haven't been touched since they were fitted.
- Many older gas fires are open-flue — they draw combustion air from the room and need adequate ventilation
- Blocked or restricted chimneys/flues can cause CO to spill into the room
- Perished seals around the fire frame let combustion gases enter the room
- Failed flame supervision devices mean the fire keeps releasing gas if the flame goes out
- Most homes with gas fires don't have a working CO alarm in the same room
Our Process
Visual & Safety
Fire body, fascia, seals, flueway and hearth area inspected. Ventilation provision to the room checked against requirements.
Burner & Injector
Burner removed, cleaned, inspected. Injector size checked against data plate. Ignition and flame supervision device tested.
Flue Draught
Flue draught tested using smoke pellet or analyser. Spillage test performed under operating conditions.
Combustion Analysis
Flue gas analysis where applicable — CO and CO₂ ratios measured to confirm safe combustion.
Reassemble & Test
Fire reassembled, fresh seals fitted as required, full operation tested, service report issued.
Why Choose Conroy
All Fire Types
Inset, outset, hearth-mounted, hole-in-the-wall, and modern flueless catalytic fires.
Burner & Injector Cleaned
Carbon and dust deposits removed from burner and injector — restores correct flame picture and efficiency.
Flue Draught Tested
Smoke test or analyser used to confirm products of combustion are clearing the flue, not spilling into the room.
Combustion Analysis
Flue gas analyser readings recorded — CO, CO₂ and CO/CO₂ ratio confirm safe combustion.
Common Parts Stocked
Thermocouples, FSDs, ignition leads and common seals carried on board for first-visit repairs.
Service Report
Written service report detailing every check, measurement and any recommendations.
Technical Detail
Open-Flue Fires
Most traditional gas fires draw combustion air from the room and vent through the chimney. They need adequate room ventilation (often a permanent air vent) and a draught-tested flue. We confirm both.
Balanced-Flue Fires
Modern balanced-flue gas fires take air from outside and vent outside via a concentric flue. Safer than open-flue but still need annual servicing of burner, seals and flame supervision.
Flueless Catalytic Fires
Flueless fires (often referred to as 'gas log fires' or 'flueless gas fires') use a catalytic converter to consume combustion products. They have strict room volume and ventilation requirements which we verify at service.
Thermocouples & FSDs
The thermocouple senses the pilot flame and holds the gas valve open. When it fails, the fire won't stay lit. Modern fires use flame supervision devices (FSDs) doing the same job electronically. Both are common stock parts.
Seals & Glass
Decorative front glass and the seals around it are common failure points — perished seals allow combustion gases into the room. We inspect both at every service and fit replacement seals where needed.
