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 efciently

through the years.

Improper installation or maintenance can cause

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.



Do not store or use gasoline or other ammable

vapors, liquids or chemicals in the vicinity of this or

any other appliance.



Do not use this heater if any part has been under

water. Immediately call a qualied 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 lter 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.
