protected from freezing.
6. Low water cutoffs, if installed, should be checked
every 6 months. Float type low water cutoff should
be flushed periodically.
7. Inspect flue passages, and clean with brushes/
vacuums, if necessary. Sooting in flue passages
indicates improper combustion. Determine the
cause and correct.
8. Inspect the vent system and air intake system, and
if the vent system is Category III, ensure that all
joints are sealed properly. If joints need to be
resealed, completely remove existing sealing
material, and clean with alcohol. Apply new sealing
material, and re-assemble.
7.2 Appliance Maintenance and
Component Description
Only genuine replacement parts should be used.
Caution
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dan-
gerous operation. Verify proper operation after servicing.
See Figure 5 for location of gas train components.
The gas and electric controls on the appliance are
engineered for long life and dependable operation, but
the safety of the equipment depends on their proper
functioning. It is strongly recommended that a qualified
service technician inspect the basic items listed below
every year.
a. Ignition controls
b. Ignitors
c. Water temperature control
d. Automatic gas valve
e. Pressure switches
f. Blowers
7.2.1 Burners
Close main manual gas valve before proceeding.
Checking the burners for debris - Remove the ignitor
inspection panels(s) and ignitor(s) and inspect the burners
through the ignitor hole(s) using a flashlight to illuminate.
If there is any indication of debris on the burners that are
visible, all the burners will need to be inspected more
thoroughly. Remove the screws from around the front of
the air box (large panel from which the ignitor inspection
panel(s) were removed), and remove the large panel.
Remove the gas manifold assemblies and the burner
panels. Inspect the burners. Clean burners, if necessary,
by blowing compressed air from the outside of the
burners into the center of the burner. A dirty burner may
be an indication of improper combustion or dirty
combustion air. Determine the cause, and correct.
Replace the burners in the reverse order
appliances or 9.2% for LP appliances (to be checked
only at full fire). When using an O
2
analyzer, the correct
O
2
is 6.8% for both Natural Gas and LP appliances.
Caution
Should any odor of gas be detected, or if the gas
burner does not appear to be functioning in a normal
manner, close main shutoff valve, do not shut off
switch, and contact your heating contractor, gas
company, or factory representative.

Maintenance
7.1 System Maintenance
1. Lubricate the system water-circulating pump, if
required, per the instructions on the pump.
2. If a strainer is employed in a pressure reducing
valve or the piping, clean it every six months.
