Overheating is the result of excessive draw, due to any of the following reasons:
• The Primary Air Valve is excessively open for the type of wood being used.
• The chimney is too big.
• Improper maintenance of the stove, which may result in air infiltration.
• Inappropriate fuel
• Door not closed correctly. ATTENTION!
During the operation of the stove, the ash pan cover must be perfectly positioned to seal the fire box.
Any uncontrolled intake of air produces overheating that can damage the stove.
HEATERS WITH ENAMEL IN MAJOLICA VERY IMPORTANT! (Applies only to certain models)
In the case of stoves enamelled in Majolica, it is normal for slight fissures to appear in the glazing,
providing the product with its characteristic appearance, once the heater is lit.
However, in the event of uncontrolled overheating, these fissures caused by the different expansion
levels of the cast iron and the Majolica enamel with vitreous components, can cause the enamel to chip.
To avoid this inconvenience, control combustion and never overheat the heater.
INDUSTRIAS HERGÓM S.A. may not be held liable for the deterioration of the stove's enamel if these
instructions are not followed.
5 - CLEANING & MAINTENANCE
Your heater is a device that is subjected to extreme temperatures and to the corrosive effects of
combustion residual materials. Regular maintenance is essential for a longer life and improved user
experience. We recommend performing the following inspections frequently.
DURING THE SEASON
• Perform a visual inspection of the chimney. Clean soot and tar if they have begun to accumulate
on the inner walls of the heater.
• Check whether the doors close tightly; adjust if necessary.
AT THE END OF THE SEASON
• Inspect and clean the chimney.
• Use the vacuum cleaner to clean inside the heater and inspect it.
• Any soot and tar (creosote) that has accumulated on the walls of the heater will hinder
performance.
• Inspect door seals. These should be replaced when they no longer seal the door perfectly.
• In the case of painted heaters, paint the cast iron parts again if necessary
CLEANING
Cleaning should always be performed when the heater is cold.

If necessary clean the ash pan housing.
Enamelled parts. (Applies only to certain models)
Preferably use a damp cloth.
Do not used strong or abrasives detergents that might damage the surface.
