5  PART D - MAINTENANCE 

 
5.1  HEAT EXCHANGERS CARE 

 

Heat exchangers must be cleaned thoroughly at the end of every heating season. 
During summer, the air in basements is damper and with minimal air circulation within 
the furnace, it can mix with creosote and/or sooth deposits in the exchangers to form 
an acid that could accelerate the corrosion process and induce premature decay of 
the steel. Corrosion damages are not covered under warranty. 
 
Smoke pipe and exchangers must be inspected regularly during the heating season. 
Access to the exchangers is easy and does not require tools; just remove the 
decorative facing by just lifting it, remove the wing nut that keeps the hinged access 
panel closed. (See pictures below)
