Make sure that the door is properly adjusted after every
maintenance operation.
ADJUSTING THE DOOR
Make quite sure that the door presses uniformly all around the
double seal to prevent dangerous fumes escaping into the air
from the pressurised furnace. Proceed as follows to adjust the
door seals:
− push the door shut and tighten the main fixing bolts (1)
until the seals start to compress;
− loosen the safety bolts (2 and 3) then fully tighten the
main door fixing bolts (1);
− re-tighten the safety bolts (2 and 3).

site the hinged side of the door.

Cleaning the boiler
Clean the boiler and remove any carbon deposits from the sur-
faces of the heat exchanger
at least once a year
. This not only
extends the boiler’s working life, but also keeps it efficient in
terms of heat output and consumption.
Proceed as follows to clean the boiler:
− open the front door (1) and pull out the turbulators (2);
9
If you need to replace any turbulators, make sure that the
replacements have the characteristics listed in the table be-
low.
− Use a flue brush (3) or other suitable tool to clean inside
the combustion chamber and the flue gas pipes;
− open the inspection window (4) and clean out any de-
posits from inside the flue gas box.
If more thorough cleaning is required, remove the flue gas box
cover (5). Fit a new glass fibre seal when fitting the cover again.
Check at regular intervals that the condensate drain (6) is not
blocked.
On completion of cleaning, follow the above steps in the reverse
order to refit all removed parts.

When using heavy oil fuels (e.g. naphtha, etc.) clean/service
the boiler more frequently and periodically check:
− clean the boiler’s heat exchange surfaces;
− check and clean the turbulators. Replace if worn or dam-
aged.
