XIII. Service and Maintenance
NOTICE Warranty does not cover boiler damage or malfunction if the following steps are not performed at
the intervals specified.
1. Continuously:
a. Keep the area around the boiler free from combustible materials, gasoline and other
flammable vapors and liquids.
b. Keep the area around the combustion air inlet terminal free from contaminates.
c. Keep the boiler room ventilation openings open and unobstructed.
2. Monthly Inspections:
a. Inspect the vent piping and outside air intake piping to verify they are open, unobstructed and free
from leakage or deterioration. Call the service technician to make repairs if needed.
b. Inspect the condensate drain system to verify it is leak tight, open and unobstructed. Call the service
technician if the condensate drain system requires maintenance.
c. Inspect the water and gas lines to verify they are free from leaks. Call the service technician to make
repairs if required.
NOTICE Water leaks can cause severe corrosion damage to the boiler or other system components.
Immediately repair any leaks found.
3. Annual Inspections and Service: In addition to the inspections listed above, the following should be
performed by a service technician once every year.
a. Follow the procedure for turning the boiler off found in the Lighting and Operating Instructions (Section
XI "Start-up and Checkout").
b. Turn off all power to the boiler.
c. Inspect the wiring to verify the conductors are in good condition and attached securely.
CAUTION
ATTENTION! Electrical Shock Hazard. Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation
after servicing.
Au moment de l´entretien des commandes, étiquetez tous les fils avant de les débrancher. Les erreurs de
câblage peuvent nuire au bon fonctionnement et être dangereuses. S´assurer que l´appareil fonctionne
adéquatement une fois k´entretien terminé.
d. Verify that the gas shutoff shown in Figure 8.1 is closed.
e. Disconnect the flexible gas line at the gas valve flare connection (Figure 13.1).
WARNING
Fire Hazard. Explosion Hazard. Always use a back-up wrench on the flare connection
when making or breaking this connection as shown in Figure 13.1. Failure to do so can cause adjacent
threaded connections to loosen or damage to the gas valve. Check all internal gas piping for leaks any
time it is disconnected or disturbed during servicing.
f.
Unplug the electrical connection to the gas valve.
g. Disconnect the air proving switch tube from the gas valve outlet tap.
h. Unplug the power and speed control cables from the blower.
