Maintenance schedule
(continued)
ƽ ƽ WARNING Have leaks fixed at once by a qualified
service technician. Failure to comply
could result in severe personal injury,
death, or substantial property damage.
Operate relief valve (if applicable)
1. Before proceeding, verify that the relief valve outlet has
been piped to a safe place of discharge, avoiding any
possibility of scalding from hot water.
ƽ ƽ WARNING
To avoid water damage or scalding due to
valve operation, a metal discharge line must
be connected to the relief valve outlet and
run to a safe place of disposal.
This
discharge line must be installed by a
qualified heating installer or service
technician in accordance with the
instructions in the EnergyRite Installation
and Operation Manual. The discharge line
must be terminated so as to eliminate
possibility of severe burns or property
damage should the valve discharge.
2. Read the pool heater pressure/temperature gauge to
make sure the system is pressurized. Lift the relief valve
top lever slightly, allowing water to relieve through
the valve and discharge piping.
3. If water flows freely, release the lever and allow the valve
to seat. Watch the end of the relief valve discharge pipe
to ensure that the valve does not weep after the line has
had time to drain. If the valve weeps, lift the seat again to
attempt to clean the valve seat. If the valve continues to
weep afterwards,
contact your qualified service
technician to inspect the valve and system.
4. If water does not flow from the valve when you lift the
lever completely, the valve or discharge line may be
blocked.
Immediately shut down the pool heater,
following the operating instructions on page 8 of
this manual.
Call your qualified service technician to
inspect the pool heater and system.
Shut pool heater down
1. Follow “To Turn Off Gas to Appliance” on page 8
of this manual.
2. Do not drain the system unless exposure to freezing
temperatures will occur.
3. Do not drain the system if it is filled with an antifreeze
solution.
3. Replace the front access door.
Test low water cutoff (if installed)
1. If the system is equipped with a low water cutoff, test
the low water cutoff periodically during the heating
season, following the low water cutoff manufacturer’s
instructions.
Reset button (low water cutoff)
1. Testing the low water cutoff shuts the unit off. Press
the RESET button on the low water cutoff to turn the
unit back on.
Check pool heater piping (gas and
water)
1. Remove the pool heater front access door and perform
a gas leak inspection per steps 1 through 6 of the
Operating Instructions on page 8.
If gas odor
or leak is detected, immediately shut down the pool
heater following the procedures on page 8.
Call a qualified service technician.
2. Visually inspect for leaks around water piping.
Also inspect the circulators, relief valve, and fittings.
Immediately call a qualified service technician to
repair any leaks.
