Dunkirk Flue & Venting Replacement in Greater Vancouver
Genuine Dunkirk flue & venting, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Flue & Venting on Your Dunkirk Boiler
The flue and venting system carries combustion products safely outside and, on sealed-combustion boilers, draws intake air in. Damaged, blocked, or improperly sloped venting is a serious safety issue and a common cause of pressure and condensate faults.
On Dunkirk systems — including models such as Q90-200, XEB, PWX — a failing flue & venting often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Dunkirk part.
