Inspect drainage. X X X Perform a visual check of the drainage system, including the air gap
funnel and drainage into the building drain.
Initiate a manual drain (refer to "Manually Initiate Tank Draining" on
page 47 ), and visually check that water flows freely through the
drain.
Perform water
analysis.
– X X Perform a water analysis on a semi-annual basis to ensure opti -
mal performance. Refer to
"Management of Scale and Chloride Levels" on
page 52 .
Inspect tank,
primary heat-
exchanger coils
and drain fitting
for scale build-
up.
X X X Adjust Blowdown Rate and FTBD Interval , as necessary, to reduce scale
build-up.
Inspect the inside of the tank, and make sure that scale build-up
does not exceed 2 in (50 mm). De-scale as required. Refer to "Clean-
ing the Tank" on page 56 .
Inspect sec -
ondary heat-
exchanger (CS/
NX model only)
for blockage.
– X X Inspect water flow through the secondary heat-exchanger and make
sure there is not blockage. Clean, if necessary – refer to
"Cleaning the
Secondary Heat-exchanger" on page 58 .
Inspect the condensate trap connected to the secondary heat-ex -
changer for blockage. Flush and prime the condensate trap, if neces -
sary – refer to "Cleaning the Secondary Heat-exchanger" on page 58 .
Inspect sacrificial
anode in the
tank.
– – X Inspect the anode for severe corrosion or scale build-up. Scrape off
excess scale – refer to "Cleaning the Tank" on page 56 . Replace the
anode, if necessary.
Clean the float
chamber.
X X X Make sure that the floats move freely. Clean the float chamber –
refer to
"Cleaning the Float Chamber" on page 59
.
Inspect the
hoses, fill valve
and drain pump
for blockage.
– X X Check the fill and drain hoses for blockage. Clean the inside of
the hoses – refer to "Cleaning Hoses, Dual Fill Valves and Drain Pump" on
page 60 .
Clean the strainer in the dual fill valves – refer to "Cleaning Hoses, Dual
Fill Valves and Drain Pump" on page 60 .
Clean the drain pump – refer to "Cleaning Hoses, Dual Fill Valves and Drain
Pump" on page 60 .
Remove dust
build-up on the
blower housing.
– X X Use an air gun to remove dust accumulation on the blower housing.
Inspect the
spark-igniter for
oxidation.
– – X Clean the spark-igniter – refer to "Cleaning the Burner Assembly" on
page 62 for details.
Inspect the
exhaust vent and
terminal.
X X X Check that there are no leaks in the exhaust vent, and it is not dam -
aged or corroded excessively. Check the vent is secured properly
and has the proper slope.
Make sure there is no blockage in the exhaust vent including the
exhaust terminal.
When operating in a stable state, make sure that flue temperature
is 275-300 °F (135-149 °C) for the standard-efficiency model. Flue
temperature should be 120-140 °F (49-60 °C) for CS/NX model.
Inspect air
intake vent and
terminal.
– X X Check the air intake vent for leaks, if used.
Make sure there is no blockage in the air intake terminal, if used.
Clean the screen on the elbow at the intake air inlet.
Inspect high
limit switch and
sensor.
X X X
Visually check that the thermocouple is attached to the exhaust vent,
and the thermocouple wires are connected properly to the switch.
