Out side part is to be manufactured from base Stones of Light concrete and inside part is to be manufactured from ceramic pipes which has rounded horizontal section.; just like Hart Classic chimney system. The insulation material is to be installed between them . Allways Hart Universal Chimney System hs to be used for furnaces which has low temperature and the chimney gas below 100°C. The waste gas of furnaces of fuel oil and natural gas have very big amount of water steam. If the waste gasses cool below 60°C in the chimney. There is going to be condenstaion. Universal Chimney System which is not effected from moisture is suitable fro this kind of furnaces.
For Hart Universal System, there are cavities on corners of base Stones. For this reason there are 4 ventilation canal between base Stone and rockwool.
The air which comes from ventilation grid on second base Stone is to be passed from inside of system with back ventilation canal. With this advantage the moisture transferred to the atmosphere . Therefore the insulation material which is to be manufactured from rockwool stays dry all the time. System has condensation liquid drainage in base section. That condensation liquid drainage system transfers the condensation liquids and rain waters to the outside.
Hart Universal System can be used in furnace which Works with coal or wood. This system adjusted for both classic furnace or modern furnace.
BASIC PACKAGE FOR HART UNIVERSAL SYSTEM:
Light concrete base Stones, Ceramic pipe, insulation material from rockwool, front plate, visor of smoke pipe, cleaning lid, condensation liquid drainage, condensation liquid blockage, ventilation grid, dilation grouting pipe, cement which is durable against acid, face mould for plaster.
