SECTION 3 - MAINTENANCE AND
CARE PROCEDURES
To be followed one month after start-up and then semi-
annually.
1. Inspect and operate all controls, gas valve and
pressure relief valve.
2. On indoor heaters, clean room intake openings to
ensure adequate flow of combustion and ventila-
tion air.
3. Keep area around heater clear and free from com-
bustible materials, gasoline and other flammable
and corrosive vapors and liquids.
4. Visually inspect the intake air filter for damage or
obstruction. If the filter is visually good, test the fil-
ter. If the intake suction reading when operating at
7500 RPM is more negative than -0.5" WC
(-0.1 kPa) replace the filter.
IF HEATER WILL NOT FIRE:
If you have no electrical power, it may be that your
"circuit breaker" has tripped. Try re-setting it.
If you have electrical power but the heater will not fire
check the following or see Troubleshooting section:
CAUTION: Combustion air must not be contami-
nated by corrosive chemical fumes which can dam-
age the heater and void the warranty.
WARNING: Check the heater for possible rodent
nests after long periods of non-use.
SECTION 2 - CAUTION
Elevated water temperature can be hazardous. The
U.S. Consumer Product Safety Commission has these
guidelines:
1. Spa 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.
2. Drinking of alcoholic beverages before or during
spa or hot tub use can cause drowsiness which
could lead to unconsciousness and subsequently
result in drowning.
3. Pregnant Women Beware! Soaking in water over
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.
4. Before entering the spa or hot tub, users should
check the water temperature with an accurate ther-
mometer; spa or hot tub thermostats may err in reg-
ulating water temperatures by as much as 4°F
(2.2°C).
5. Persons with a medical history of heart disease, cir-
culatory problems, diabetes, or blood pressure
problems should obtain a physician's advice before
using spas or hot tubs.
heater will enter a post-purge period and then retry
the ignition cycle or lockout, depending on the
heater configuration.
20. Once gas is flowing, the manometer reading will
drop to -0.2” +/- 0.1" WC (-0.05 +/- 0.02 kPa) at
ignition and will read -2.0" +/- 0.5" WC
(-0.5 +/- 0.12 kPa) at high fire (7500 +/- 50 RPM
fan speed). See the instructions on page 42 for
adjusting the valve manifold pressure if the read-
ing is not within tolerance.
21. Visually check through the sight glass that the
heater is on and heating. An orange glow indi-
cates that the heater is running. At high fire, the
flame should be visible. The flame should be blue
in color with some orange streaks when the
air/fuel ratio is correct. See the visual inspection
instructions on page 43 for additional information.
22. Remove the manometer and replace the bleedle
plug.
23. Reinstall top panel, install the two screws at the
rear and knurled screw above the control panel.
24. Feel the inlet and outlet pipes. Outlet pipe should
be 10ºF to 20ºF (6ºC to 11ºC) warmer than the
inlet. It should not be hot.
6. Persons taking medications which induce drowsi-
ness, such as tranquilizers, antihistamines, or anti-
coagulants, should not use spas or hot tubs.
