INSTALLATION INSTRUCTIONS
- Position the elements with the female socket facing up.
- Use the sliding element for the male-female connection and always maintain a 3° slanting angle on horizontal installations.
- Observe the compression loads and the non-vertical installations.
ESSENTIAL FEATURES
Resistance to the wind load:
- Distance between wall brackets: NPD m
- Free length from the last bracket: 3 m
Compressive strength:
- Linear elements’ maximum load: 30m
- Maximum load of a straight fitting at 90°: 30m
- Maximum load of the wall chimney support
30m Tensile and bending strength (linear elements):
- Maximum load at traction (element connection means and chimney connections): NPDm
- Non-vertical installations: NPD
- Non-vertical installations: distance between wall chimney supports = NPD
Traction and bending strength (non-linear elements):
- Non-vertical installations: NPD
FLUE SYSTEM MAINTENANCE
Scheduled maintenance carried out by qualified personnel:
- Unless standards dictate otherwise or different agreements are reached with the user, the following maintenance schedule is advisable:
- gaseous fuels: 1 / year;
- liquid fuels: 1 / 6 months;
- Clean the smoke duct with a soft plastic brush or sponge as well as the equipment compartment for pipe supply and ventilation, the inspection fitting and chimney and also make sure the smoke/fumes and condensates etc., are flowing freely.
