Answer 1
- Is the system switch on?
- Is the thermostat up to temperature?
- Is the pump running with a clean filter less than or equal to
16 psi on pressure gauge?
- Is the gas valve in the on position?
- Is the pilot lit?
- Is the gas supply valve open?
- Are all plumbing and filter valves open?
- If a bypass is installed, is it properly adjusted?
- Contact a qualified technician if you still cannot find the
problem.
Answer 2
This could be due to low gas pressure, inadequate air supply, or
improper venting. Make sure gas is turned on; with propane, make
sure the tank has fuel. Also check for water run-off from roof or
sprinklers.
Answer 3
The thermostat may be set too low. If the heat loss is greater than
the heater input - the heater may be too small, outside air
temperature is too low, inadequate gas supply. You may want to
install a solar cover to slow heat loss.
Answer 4
Inadequate water flow due to a dirty filter, closed valve, external
bypass needs adjusting, reversed water connections, or pressure
switch out of adjustment. It is also possible that your thermostat
is out of calibration or needs replacing.
Answer 5
See previous two questions for additional information. Also check
for water run off from above or sprinklers directed at heater. A
high wind stack may be needed due to heater location. Further
troubleshooting will require a service technician.
Answer 6
Review the Owner's Manual if you do not find your answer, turn the
heater off and contact a qualified service.
Answer 7
The heat exchanger may be leaking because of chemical or sanitizer
damage. The damage may be from winter freeze - usually leaking upon
spring start-up. Contact a qualified pool service technician.
Answer 8
This may be caused by condensation (occurring when heating very cold
water); a missing or damaged bypass; or excessive water flow through
the heater from an oversized pump.
Answer 9
Either low gas pressure and/or inadequate air supply and venting,
review the installation requirements in the Owner's Manual. Both
conditions may need to be evaluated by a qualified service
technician.
Answer 10
One, or a combination of the following: low gas pressure,
downdrafting, air supply, and venting. The heater may need a high
wind stack, if installed near a vertical wall or windy area. Contact
a qualified service professional.
Answer 11
Sanitizers or chemical imbalance can deteriorate protective coatings
on heater components and create rust. Rebalance chemicals and
replace damaged components.
Answer 12
Low gas pressure can cause whistling in the burners. Check your
Owner's Guide or contact your installer.
Answer 13
No. Hayward heaters cool down immediately after shut down.
Answer 14
All heaters should be installed on a non-combustible material, such
as concrete or block.
Answer 15
Yes, specific conditions apply. Please consult your Owner's Manual
for complete details.
Answer 16
Propane heaters use one gallon of fuel per hour for each 91,000
BTU's of heater input.
Example: A 250,000 BTU heater uses: 250,000/91,000 = 2.75 gallon per
hour
Natural gas heaters use one therm (100,000) BTU per 100,000 BTU's
heater size. Your gas is usually billed by therms.
Answer 17
- Purchase an energy efficient model.
- Use a pool blanket on your oasis when not in use.
