SECTION IX - MAINTENANCE SCHEDULE AND LUBRICATION REQUIREMENTS
e. Check the voltage and amps on all motors.
f. Check the operation of all safety limits and con-
trols. Clean and recalibrate or replace.
g. Check the operation of the automatic gas shut-
off valves, and check them for leakage at the
pressure test ports provided.
h. Inspect all electrical components, connections,
and terminals. Clean or replace and tighten as
necessary.
i. For DDC Controls: Check that the battery in
the UC-01 controller has 3 VDC. CAUTION: Do
not remove the battery with the power to the
unit turned off.
6. Off Season or Yearly
a. Complete the monthly and quarterly mainte-
nance schedules.
b. Inspect, and if necessary, clean all fan wheels,
props, and housings.
c. Check all nuts and bolts for tightness.
d. Inspect all bearings and check condition and
alignment.
e. Check the condensation lines for any leaks or
blockages (if applicable).
f. Inspect all burner components.
g. Clean fl ame sensor, ignition electrodes, and
check for cracks.
h. Test the fl ame safeguard relay (RE-02) and
replace components if necessary.
i. Inspect all regulators, relief valves, motorized
valves, solenoid valves, vent valves, manual
shut-off valves, and safety shut-off valves.
Check their operation and clean or replace as
necessary.
j. Inspect and clean all drip legs in fuel lines and in
the fl ue.
k. Remove the rear panel and the rear header box
cover. Inspect the header box and tubes. Look
for carbon deposits, soot, scale or rust. Clean if
necessary.
l. Inspect the combustion chamber for carbon
deposits, soot, scale, or signs of fl ame impinge-
ment. Clean if necessary. If there is evidence of
fl ame impingement, a complete burner adjust-
ment must be made.
m. Lubricate fan motors as directed by motor manu-
facturer. Inspect motors for loose connections.
n. Lightly oil all door latches.
o. Check that the cabinet is weather-tight. Replace
door gaskets and re-caulk as needed.
p. Check the CO level in the entering and leaving
airstream of the furnace. If the CO is greater in
the leaving airstream, it is possible that the heat
exchanger is leaking CO into the airstream. The
leak must be located and repaired or replace the
heat exchanger.
NOTE: Keep screened air intakes clear of obstruc-
tions at all times.
WARNING: Failure to comply with the general
safety information may result in extensive
property damage, severe personal injury or
death.
Periodic maintenance is essential to the effi cient
operation and extended service life of this equipment.
Failure to provide maintenance as recommended may
void the equipment warranty.
A. Maintenance Schedule
1. Daily
a. Check gauges, monitors, instruments and equipment
settings.
2. After 8 hours of operation
a. Check that fan belts are tight and sheaves are aligned.
The fan belts can be checked every 30 days after the
fi rst 60 days of new belt run-in. CAUTION: Do not
overtighten belts.
b. Check set screws and bolts on the fan, bearings, cou-
plings, and burner assembly.
c. Check gas pressure at regulator.
3. After 48 hours of operation, check bearings for any
unusual vibration or excessive temperature.
4. Monthly
a. Check all valves, piping and connections for-
leaks.
b. Check the pilot and burner fl ame signal, and
safety lockout (RE-02).
c. Check the fuel pressure in the fuel supply line to
each heater.
d. Check the burner manifold pressure and draft.
e. Do a fl ue gas analysis.
f. Inspect fi lters. Clean or replace as necessary.
g. Inspect main fan bearings; lubricate if necessary.
See following section on bearing lubrication.
h. Check all dampers, damper actuators and link-
ages. Adjust and tighten if necessary.
i. Inspect area and make sure that no combustible
or hazardous material has been stored within
clearances as shown on the specifi cation plate.
j. Check for any vibration or unusual noise. If any is
observed, locate the cause and correct.
k. Ensure the supply, discharge, combustion air,
vents, and stack remain clean and open.
l. Check and clear air sensing tubes and fi ttings.
CAUTION: Remove tubes from switches and
transducers before using compressed air to blow
through tubing.
5. Quarterly
a. Complete the monthly maintenance schedule.
b. Inspect all drives for proper belt tension, wear,
and alignment.
c. Check that bearings, fans, props, sheaves, and
coupling setscrews are securely locked to the
shaft.
d. Remove pilot assembly. Clean and adjust if nec-
essary. (Refer to burner manufacturer IOM).
