sional service technician reassemble the heater as
follows:
1. Attach the copper tubing to the pressure switch
(see Figure 22).
2. Tighten the drain plugs.
3. Turn on the filter pump and circulate water
through the heater for five (5) minutes. Check for
leaks while circulating.

9.3
inspection and service
The Legacy heater is designed and constructed
to provide long performance life when installed and
operated properly under normal conditions. Periodic
inspections, especially at spring start-up, are impor-
tant to keep your heater running safely and efficiently
through the years.
WarninG
Improper installation or maintenance can cause
nausea or asphyxiation from carbon monoxide in
flue gases which could result in severe injury, or
death.
9.3.1 owner inspection
Zodiac recommends that you inspect the heater
on a continual basis and especially after abnormal
weather conditions. The following basic guidelines are
suggested for your inspection:
1. Keep the top and surrounding area of the heater
clear of all debris.
2. Keep the area around and beneath the heater
clean and free of all combustible materials such
as paper, leaves, etc.
Caution
Do not store or use gasoline or other flammable
vapors, liquids or chemicals in the vicinity of this or
any other appliance.
WarninG
Do not use this heater if any part has been under
water. Immediately call a qualified service techni
-
cian to inspect the heater and replace any part of
the control system and any gas control which has
been under water.
3. If the heater is equipped with a pressure relief
valve, check for corrosion in and around the
valve. Twice a year, with the filter pump on, lift
the release lever on the top of the valve to make
sure that water runs freely through it. If corrosion
is found, replace the pressure relief valve. When
replacing the valve, be sure that the pump is off.
Install the valve so that the discharge is directed
away from any area that may be damaged by
water.
4. Be sure all combustion air and ventilation
openings are not blocked. Check for spider webs
and other debris inside the heater, in the vents on
all sides of the heater jacket and in the exhaust
outlet– especially after a long period of nonuse.
