f) Regular adjustments
The user must imperatively keep watch on the installation and the instruments of the boiler,
and ensure regularly that there is no external leak, especially on the joints of the boiler
(thermic discharge security valve, water flow and return, the glove pipe, drainage, join to the
water tank...)
All leaks shall immediately be stopped. External leaks are not covered by the factory
guarantee.
g) Maintenance of storage tanks with domestic hot water built-in tank
Our domestic hot water storage tanks are coated enameled steel and needs an annual
revision of their protective magnesium anode. This must imperatively be replaced if
necessary. The storage tanks equipped with an inspection hatch can be maintained internally
(descaling for example) when it is necessary (requires a new gasket)
1.3.14
Wear and tear of the refractory material, hanging plates and seals
The refractory material, metallic tunnel, hanging plates, and the seals are pieces/items
which will be under wear and tear during the lifespan of the boiler, according to different
types of woods, greater or lesser use of the boiler, the maintenance quality of the boiler.
This is perfectly normal and these pieces/items must be replaced, only when they are not
fulfilling their functions.
Generally, a crack or crumbling would not justify being replaced, when they are still doing
their job.
The removable hanging plates positioned in the burning chamber are equally submitted to
high temperatures and can be deformed or altered over time. To limit their normal wear and
tear we must avoid accumulating a large bed of cinders, leaving the cinders to consume for a
long time before reloading with fuel.
When loading the fuel, never "throw" the logs in the burning chamber, but place them
"gently". The refractories are sensitive to shocks and more particularly to heat.
A poor operation of the boiler (not enough evacuated energy of the boiler = slowing
down) provokes premature wear and tear of the refractories, the seals and the removable
hanging plates. See the start of directions for proper use
The boiler must never in any case be installed in a wet atmosphere.
