Flue elbows
FIREFIX Pellet Pipe Elbow 90°, Ø 80 mm (3.15 in)
The pellet elbow: Ø 80 mm (3.15 in) in 1.2 mm steel, with a rubber seal already fitted and a temperature class stated to 200 °C (392 °F).

What the listing actually contains
A 1.2 mm (0.05 in) pellet pipe elbow, black. Ninety degrees, without a cleaning opening, with
a fitted rubber seal. Eighty millimeters diameter. Temperature class to 200 °C (392 °F).
Tested and approved to DIN EN 1856-2:2009.
Five lines, five specifications.
The seal is the whole difference
A log stove elbow pushes together and relies on the flue’s own negative pressure.
This one arrives with a rubber seal already fitted.
A log stove draws: the flue sits slightly below room pressure, so an imperfect joint
pulls a little room air inward, which is untidy and nothing more.
A pellet appliance pushes. A fan drives the exhaust, the flue runs at positive
pressure, and an imperfect joint pushes flue gas and pellet dust out — into the
room the pipe is standing in.
That is why pellet flue seals exist at all, and why this
elbow does not ask the buyer to source one.
Two hundred degrees, and why that is right
A far lower class than a solid-fuel elbow needs.
It is not a weaker component. It is a component for a machine that runs cool. A
pellet appliance burns efficiently and its flue gas is modest; the seals that make
its joints gastight set the ceiling.
This elbow’s class matches that. The whole pellet flue system is built
around it, and a 600 °C (1112 °F) log stove elbow would be the wrong part here just as surely
as this one would be on a wood stove.
No cleaning opening, stated
Which is worth knowing, because the bend is where a pellet flue fouls.
Pellet appliances produce fine ash, and it settles wherever the gas slows — which is
at every change of direction. Some elbows carry a cleaning door; this
one states plainly that it does not.
The consequence is that clearing it means taking the pipe apart, and on a sealed,
positive-pressure system that also means the seal gets disturbed. A replacement
seal is a separate purchase.
One point two millimeters
Between a thin 0.6 mm (0.02 in) aluminized or stainless elbow and a 2 mm (0.08 in) mild
steel one.
That is the pellet gauge: lighter than a log stove’s pipe because the duty is
lighter, heavier than a thin stainless liner because it is a visible, handled
component.
The standard, with its year
DIN EN 1856-2:2009.
The listing names the standard with its date and pairs it with a temperature
class. That combination — a class, under a named document, with an edition — is a
complete certification statement.
