Halaman CetakWARNING: always switch off the heater and isolate the gas and electricity before carrying out any
service or maintenance operation.
Order of maintenance
•
First clean the heater and filters as described below by daily maintenance. Take the venturi (22) out
during cleaning to remove dust directly behind it.
•
Clean the reflector and other parts with water and mild detergent and a cloth or soft brush.
•
Carefully inspect the outer and inner burner globes on damage, cracks and holes. Replace when
needed.
•
Check the gas injector for obstructions. Remove obstructions by brushing them away and by using
a pin or drill to clean the injector hole. Make sure that the injector hole does not become wider by
using a pin or drill that is larger than the size stamped on the side of the injector.
•
Pay special attention to the dual injection model Di. (See parts list for numbers). Clean the holes in
injector (32) very carefully. Gas soundness is achieved by a metal to metal connection with part (34).
So, keep clean and inspect for damage and avoid making scratches on the contact surfaces of both
parts. Make sure that the small o-ring (33) (4 mm) is still in place in the seat behind the injector and
does not get lost during cleaning.
•
Clean the inside of the gas safety device and injector with compressed air. Make sure that the
pressure of the compressed air is not larger than the 1,5x the pressure mentioned on the data plate
(300 till 1400 mbar). Otherwise the rubber seals inside the safety device will become damaged.
•
Check the condition of the thermocouple sensor. Replace in case the tip is burnt-in already to avoid
unnecessary shut down later on. The end of the thermocouple shall be 25 or 22 mm above the upper
plate of the burner (see picture next page).
•
Check the condition of the spark plug; no cracks of the ceramic and a spark gap of 3-4 mm. Check
if the metal spark wire and earthing wire still makes a 90 degrees angle directly above the ceramics
and are not bending away to larger angles.
•
Clean the EID2G and check the connection of the ignition wire for proper contact and watertightness.
Check if the ignition wire is not damaged and has no cracks.
•
Check all gas carrying parts and connections for gas tightness with leak detection liquid or soapy
water according the procedure in the standards applicable at the local installation situation. Never
use a flame for soundness checks!
•
In case a gas hose is used, check this carefully for cracks, wear and other signs of damage or
alteration. Replace it also when the maximum lifetime printed on the hose, or the maximum allowed
by local requirements, has been passed.
•
Commission the heater after maintenance and check it carefully during first ignition, firing and
extinguishing.
In case the heaters need to be stored for a long time, make sure that no dust, spiders, etc. can enter the
heater. Use the carton packaging box to store the heater, or a plastic bag if the box is not available
anymore, and close this carefully.
Daily maintenance
In dusty or dirty environments check and clean a heater every day. In case a heater is not cleaned
internally the heat efficiency will drop and the lifetime of the inner and outer burner globe will become
shorter or they will be destroyed. Also, there is a possibility that carbon monoxide (poisonous) will be
produced and soot deposit will occur. It is very important to keep the heater internally and externally free
of dust. Inspect and clean also every day the combustion air openings into the building and the proper
functioning of exhaust fans.
Dust filter 2F (if applicable)
Dust filters must be check
every day and cleaned in case
needed. Remove a filter before
cleaning. Dry dust can be
removed by tapping the filter
softly against a solid surface
like the sole of a shoe. The
dust will fall off easy now. In
case the filter is still not clean, brush the surface gently with a brush or clean it with compressed air from
inside to the outside. In case the dust is greasy, clean the filter in warm water with a bit detergent. Make
sure that filters are dry before placing them back. Even with the use of a filter still check the heater
regularly inside while very fine dust still will pass the filter and pollute the heater internally.
