2. Cannot obtain Maximum or High fire :
-
Open circuit to regulator coil;
Measure coil resistance = 127
Ω
;
-
Short circuit between coil and casing;
Check resistance between one terminal
and casing, reading indicates short
circuit;
-
Low voltage to regulator;
Check for correct voltage range, should
be: 0 - 24 V DC;
-
Low gas supply pressure;
Check natural gas GB = 17.5-20.0
mbar. Push down plunger, burner
pressure should rise to high-fire rate;
3. Erratic operation:
-
Fluctuating or pulsating DC voltage ;
Check using meter, if pulsating suspect
input signal, transients, etc ...
4. Minimum rate lower than setting required or
below 1.5mbar :
-
Minimum pressure set too low; re-adjust;
-
Line supply gas inlet control regulator
faulty or requires adjustment;
Appliance gas tap not fully open
5.8 Handing over
Upon satisfactory completion of commissioning
and testing, hand the instructions to the user or
their representative. Advise the appropriate
person how to safely use and operate the air
heater and describe the use of appropriate
external controls. Ensure that the person
understands how to start the heater and how to
turn it OFF.
Suggest that the instructions are placed close to
the air heater for future reference. In the absence
of an appropriate location fix them to the gas
service meter. Ensure they are not placed where
they may restrict the airflow from the heater or
where they may catch fire from a hot surface
.
Do not fix them in the control section.
Advise the person who is resuming responsibility
that for continued safe operation the air heater
should be serviced at least once a year.
6.0 SERVICING INSTRUCTIONS
IMPORTANT:
Only appropriately qualified persons may carry
out servicing and fault finding on this gas fired
equipment
.
Before commencing service ensure
that both the gas and the electricity are turned
and switched "OFF" and that the air heater has
cooled down.
Inadvertent substitution or replacement of
components similar to those specified or
replacement in a manner contrary to the method
herein described could constitute a hazard and
lead to prosecution.
Reznor EURO-C 4000 RJL air heaters will operate
with a minimum of maintenance. To ensure long
life and satisfactory and safe performance, an air
heater that is operated under normal conditions
should be inspected and cleaned at the start of
each heating season. If the air heater is operated
in an area where unusual amounts of dust, etc
are present in the air, more frequent servicing is
recommended.
When any service is completed, be sure that
components are reassembled correctly to ensure
that no unsafe condition exists.
Upon completion of the service carry out the
commissioning instructions outlined in section 5
of this document.
WARNING:
Excessive dirt buildup on the inside of the burner
ports could cause unburned gas to spill out of the
back of the burner tube causing a fire or
explosion. To prevent this occurring,
clean all of
the burner ports at least annually.
CAUTION:
When cleaning air heaters, wearing of eye
protection and a dust face mask is
recommended.
6.1 Service procedure
The following procedures should be carried out at
least annually:
1. Remove the burner assembly as in section
7.1. Clean thoroughly, (cleaning the burners
requires an emery cloth, wire brush and a
cleaning cloth -stubborn deposits on burners
are best cleaned using
"acetone"
as a
solvent).
*Check the condition of the igniter and clean
to remove all deposits. Check the spark gap
(3,0 mm).
*Check the sensor - clean as necessary.
*Remove any soot deposits from the burner
with a wire brush. Clean the ports with a
degreaser or acetone. A vacuum cleaner or
compressed air may assist in this cleaning
operation. Wipe the inside of the burner tube
clean (cleaning thoroughly with a degreaser
as recommended will retard future buildup of
dirt).
Inspect the burner for any damage or
deterioration. If the burner is damaged or
corroded, replace it.
2. The heat exchanger should remain clean
unless a problem has developed due to poor
combustion. Examine the heat exchanger
tubes internally and externally for any sign of
deterioration. The outside of the tubular heat
exchanger can be cleaned from the front of
the heater with an air jet and/or a flexible
brush. Remove any dust and grease deposits.
