MAINTENANCE

WARNING! MAINTENANCE MuST ONLY BE uNdERTAkEN BY A quALIFIEd PERSON. WE STRONGLY RECOMMENd THAT
ALL SERVICING IS dONE BY YOuR LOCAL SERVICE AGENT.
Looking after your AB heater will pay dividends, ensuring heat as and when you need
it and avoiding frustrating operational problems.
IMPORTANT! We strongly recommend that you arrange for heater servicing
during the summer months to avoid being left without heat during the winter.
 WARNING! unplug unit from mains power supply before opening or
servicing heater. See Section 1 regarding electrical safety and maintenance.
6.1. General. Keep the heater clean; wipe outer case with a damp, clean cloth. Do
not use abrasives. Clean fuel tank with a dry cloth. Oil wheels if necessary.
Check heater for damage and immediately repair or replace with authorised
parts. Contact your Sealey Service Agent.
6.2. Spark plug (electrode). Remove, clean and check that the plug gap is 3mm
(fig.7). For paraffin check the plug on a monthly basis (or if you have starting
problems). If using diesel clean plug every 50 hours (or once every working
week if less than 50 hours).
6.3. Air filter. The cast alloy compressor unit is protected by an extra large filter
element. The filter should be cleaned regularly, especially if the appliance is
used in a dusty environment. Remove filter end cover, take out the filter, wash it
using a light detergent and dry thoroughly before re-installing. Replace the filter at least once a year.
6.4. Fuel filter. The fuel line is fitted with an in-line filter. To clean the filter, remove and wash in paraffin.
6.5. Flame-out device. The AB heaters are fitted with a flame-out device (a cadmium cell, see fig.6) which cuts the fuel supply
should the flame be inadvertently extinguished, or if the unit overheats. If this happens, switch off the heater and unplug
from the mains supply. Check the heater to determine the fault. In particular check that the air intake is not obstructed and
that the internal fan is rotating freely. Wait a few minutes and restart the unit. If the problem persists contact your local
Sealey Service Agent.
6.6. Fan. Fan blades should be cleaned every 500 operating hours (depending on environment). Remove the outer case and
clean the fan blades with a paraffin moistened cloth or very light solvent. Dry fan thoroughly using compressed air.
