3. If the heater is equipped with a pressure relief
valve, check for corrosion in and around the valve.
Twice a year, with the lter pump on, lift the release
lever on the top of the valve to make sure that water
runs freely through it. If corrosion is found, replace
the pressure relief valve. When replacing the valve,
be sure that the pump is off. Install the valve so that
the discharge is directed away from any area that
may be damaged by water.
4. Be sure all combustion air and ventilation
openings are not blocked. Check for spider webs
and other debris inside the heater, in the vents on
all sides of the heater jacket and in the exhaust
outlet– especially after a long period of nonuse.
8.3.2 Professional Inspection
Inspections performed at least once a year by
a qualied technician are required to maintain your
heater's safe and efcient operation. The following basic
safety checks must be performed.
1. Inspect the venting system for blockage, leakage,
and corrosion.
2. Check for spider webs or other obstructions in the
main burner orices – especially at spring start-up.
Clean with wire brush if necessary.
3. Check for loose or broken wires and terminal con-
nections.
4. Inspect the electrical controls, specically the
following:
a. High limit controls.
b. Water pressure switch.
c. Power interface/Temperature control.
d. Ignition control.
e. Automatic gas valve.
f. Roll-out switch (fusible link).
g. Control circuit fuse.
h. Vent temperature limit.
5. Inspect the external surfaces of the heat exchanger
tubes for black carbon soot buildup by placing a
mirror between and under the burners when the
heater is ring. Remove any soot that has collected
on the tubes, and correct the cause.
NOTE After installation and rst 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.
6. Make sure that the pressure switch operates
properly by shutting the lter 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.
7. Conduct a normal operating cycle and observe that
the sequence proceeds as intended.
For your safety, when starting the heater, keep
your head and face away from the burner area
opening to prevent any risk of personal injury.

votre visage loin du brûleur pour éviter tout risque
de blessure.
AVERTISSEMENT
8. Make a visual check of the main burner ame. The
ame can be seen in a mirror arrangement held
beneath the burners. The ame should be:
a. Blue in color.
b. 1 to 4 inches (25mm to 102mm) above burner
surface. See Figure 26.
9. Perform a temperature rise test in accordance with
Section 7.8.
Section 9. Troubleshooting
9.1 General Heater Troubleshooting
Table 8 lists some of the more common problems,
causes and solutions encountered when running the
heater. Most problems occur when the heater is being
started for the rst time after installation or at spring
start-up. Careful installation and maintenance will
help ensure years of trouble free use from your Legacy
heater.
9.2 Service Codes
The Legacy Model LRZ electronic controller
monitors several functions of the heater. In the event
of a malfunction, the Legacy controller will display a
FAULT message. Table 9 lists the Legacy Model LRZ
electronic Heater Service Codes along with potential
causes and remedies.
