CLEANING THE HEAT EXCHANGER AND THE COM- BUSTION CHAMBER
For the heater to operate efficiently the heat exchanger and combustion chamber must be cleaned after a period of prolon- ged use and more frequently if too much soot builds up. Soot builds up when there is not enough chimney draft, when the fuel is of very poor quality, when the burner is regulated incorrectly or when the heater is switched on and off too frequently. If the heater starts vibrating when it is turned on there is probably too much soot.
To get at the internal parts of the heat exchanger (1), remove the burner (2), take off the upper back panel (3), the exchanger inspection panels (4) and the baffle plates (5). Clean out soot or extraneous material with a vacuum cleaner or tube cleaner.
