NOTE
: Keep this manual in a safe place for
future reference by you and your professional
technician when inspecting and servicing the heater.
8.3.2 Professional Inspection and
Maintenance
Inspections performed at least once a year by a
qualified technician are required to maintain your
heater's safe and efficient operation. The following
basic safety checks must be performed.
1.
Check for loose or broken wires and terminal
connections.
2.
Make sure that the pressure switch operates
properly by shutting the filter pump off and on a
few times. The burner should go off immediately
after the pump stops. An ignition sequence
should start shortly after the pump is turned back
on.
3.
Inspect the electrical controls, specifically the
following:
a.
High limit controls.
b.
Water pressure switch.
c.
Fuel burner operation.
d.
Temperature control.
e.
Control circuit fuse.
f.
Ignition control.
g.
Cad cell.
4.
Inspect the venting system for blockage, leakage,
and corrosion.
5.
Replace the in-line oil filter cartridge once a year.
6.
Check for spider webs or other obstructions in
the air shutters and bands especially at Spring
start-up. Clean with wire brush if necessary.
7.
Conduct a normal operating cycle and observe
that the sequence proceeds as intended.
8.
If the heater is equipped with a pressure relief
valve, clean any accumulated corrosion and
make sure that water runs freely.
9.
Inspect the inside of the firebox and burner for
deterioration and indication of improper opera-
tion.
10. Perform a temperature rise test in accordance
with Section 7.7 of this manual.
11. Regularly inspect electrical controls for deteriora-
tion. Repair and replace as necessary.
12. Clean the heat exchanger using the following
schedule:
After installation and first start-up, check the
heat exchanger for black carbon soot buildup
after the following periods of operation: 24 hours,
7 days, 30 days, 90 days and once every 6
months thereafter, preferably at the end of the
swimming season.
Caution
Black carbon soot on a dirty heat exchanger can,
under certain circumstances, be ignited by a random
spark or open flame. To prevent this from happening,
dampen the soot deposits with a wet brush or fine
water spray before servicing or cleaning the heat
exchanger.
Caution
Be careful to avoid damaging the firebox material
when cleaning the heat exchanger or inspecting the
heater. Keep water out of the firebox. Be sure to
replace the gasket, inspection plug and retainer when
the cleaning or inspection is complete.
Clean the heat exchanger as follows:
a.
Remove the heater top assembly and flue
collector.
b.
Remove the inspection hole cover (see Fig. 15).
c.
Remove the V baffles (the retaining wire does
not have to be replaced)
d.
Use an ordinary kitchen brush to brush across
the top of the heat exchanger between the tube
fins.
e.
Use a bottle brush to brush down between the
tube fins toward the firebox.
The ash can be softened for easier removal by
lightly dampening with a wet brush. Do not let water
get in the firebox.
DO NOT
use a water hose to clean
the heat exchanger while it is still installed in the
heater. Water will damage the firebox material.
f.
Reach through the inspection hole and brush
across the bottom of the tube fins using the
kitchen brush.
g.
Carefully remove all dirt and soot from the
firebox by inserting a vacuum cleaner nozzle
through the inspection hole.
h.
Replace the flue collector and top assembly.
For more thorough cleaning, remove the heat
exchanger completely and wash it with a garden hose.
