checked every 6 months. Float type low water
cutoff should be flushed periodically.
6.
Inspect flue passages, and clean with brushes/
vacuums, if necessary. Sooting in flue passages
indicates improper combustion. Determine the
cause and correct.
7.
Inspect the vent system and air intake system,
and 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 Laars replacement parts should be used.
Caution
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after
servicing.
See Figures 7 through 11 for location of gas train
and control 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.
7.2.2 Filter
The filter used in the Pennant is washable with an
83% arrestance. Since the filter is washable, it will

Spas are excellent for relaxation, body-
conditioning and for arthritic and rheumatic
problems, but can be hazardous.
WARNING
The U. S. Consumer Product Safety Commission
has warned that elevated temperatures in spas and
hot tubs can be hazardous. Follow these “Safety
Rules for Hot Tubs:”
•
Spa or hot tub water temperatures should never
exceed 104°F (40°C). A temperature of 100°F
(38°C) is considered safe for a healthy adult.
Special caution is suggested for young children.
•
Drinking of alcoholic beverages before or
during hot tub use can cause drowsiness,
which could lead to unconsciousness and
subsequently lead to drowning.
•
Pregnant women beware! Soaking in water
above 102°F (39°C) can cause fetal damage
during the first three months of pregnancy
(resulting in the birth of a brain-damaged or
deformed child). Pregnant women should stick
to the 100°F (38°C) maximum rule.
•
Before entering the spa or hot tub, users should
check the water temperature with an accurate
thermometer; spa or hot tub thermostats may
err in regulating water temperatures by as
much as 4°F (2°C).
•
Persons with a medical history of heart disease,
circulatory problems, diabetes or blood pressure
problems should obtain their physician’s advice
before using spas or hot tubs.
•
Persons taking medications which induce
drowsiness, such as tranquilizers,
antihistamines or anticoagulants, should not
use spas or hot tubs.
SECTION 7.
Maintenance
7.1 System Maintenance
1.
Lubricate the system water-circulating pump, if
required, per the instructions on the pump.
2.
Inspect the venting system for obstruction or
leakage at least once a year. Periodically clean the
inlet air filter and the screens in the vent terminal
and combustion air terminal (when used).
3.
Keep the appliance area clear and free from
combustible materials, gasoline, and other
flammable vapors and liquids.
4.
If the appliance is not going to be used for
extended periods in locations where freezing
normally occurs, it should be isolated from the
system and completely drained of all water. All
systems connected to it should also be drained or
protected from freezing.
5.
Low water cutoffs, if installed, should be
