Page 35: Maintenance
5. MAINTENANCE MAINTENANCE OF THE EXCHANGERS The flue pipe and the exchangers should be inspected regularly during the burning season. Easy access is provided (without the use of tools): simply unscrew the wing nut on the exchangers access door. See pictures below. WARNING: THE HEAT EXCHANGERS ARE TO BE CLEANED THOROUGHLY AT THE END OF EACH HEATING SEASON. -
Page 36: Chimney Maintenance
CHIMNEY MAINTENANCE The most efficient method to sweep the chimney is using a hard brush. Brush downwards so soot and creosote residues will come off the inner surface and fall at the bottom of the chimney where they can be removed easily. The chimney must be checked regularly and if creosote has accumulated, it must be removed without delay. -
Page 37: Replacement Parts
6. REPLACEMENT PARTS Your PSG furnace is designed to burn clean and requires little maintenance. It is recommended to conduct a visual inspection at least once a month to uncover any damage to the unit. Any defect must be repaired without delay using genuine PSG replacement parts. -
