INSTRUCTIONS
FOR YOUR SAFETY - READ BEFORE OPERATING
A
WARNING:
IF YOU DO NOT FOLLOW THESE
INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION MAY
RESULT, CAUSING PROPERTY DAMAGE, PERSONAL
INJURY OR LOSS OF LIFE.
INTRODUCTION
Your pool/spa heater has been designed for years of
safe and reliable pool/spa water heating. It is available
with electronic ignition. This manual provides installation,
operation, maintenance, and service information for these
heaters.
F10316
With proper installation and setup, operation of the heater
is straightforward. The upper front panel of the heater
contains the control center that allows you to turn the heater
On or Off, select the mode of operation, and adjust the
temperature settings for the pool or spa. The temperature
range is factory set from 50°F (18°C) to 104°F (40°C).
See figure above for location of toggle switch to turn the
heater On and Off. Section 4 of this manual contains more
details about the use of the controls (starting on "Control
Adjustments" on page 28).
Start-Up Procedures
1.
Clean air louvers of dust, lint and debris.
2. Keep heater area clear and free from combustibles,
flammable liquids and chemicals.
3.
Remove the top panel by removing the two screws at
the rear of the heater and the knurled screw above
the control panel. Lift the top panel off and set it
aside. Visually verify that the filter box intake is not
obstructed and that the filter is clean.
4. Water must be flowing through the heater during
operation. Ensure that the system is filled with water
and the pump is operating. Double check for any
water leaks.
5.
Purge air from the gas line. Insufficient purging may
keep the heater from lighting on the first try.
6.
Double check gas connections, make sure no leaks
are present. Use soapy water to inspect.
7.
Double check incoming electrical power, verify
sufficient supply of 120V/1ph/60Hz power to the
heater.
8. If installed indoors, make sure flue gases are vented
properly, and that combustion and makeup air
openings are adequate and clear of obstruction.
9.
Verify that the fuel type of the unit matches the supply
gas.
10.
Locate and turn the manual gas valve ON.
11.
Locate the plugged bleedle valve on the pipe
downstream of the gas valve.
12.
Remove the bleedle plug and connect a manometer
capable of reading up to -24" WC (-6 kPa).
CAUTION:
The X94 manifold and blower suction
pressures measured at this point are negative, and can
be as high as -19" WC (-4.73 kPa) when the blower is
at full speed and the gas valve is closed. Verify that
manometers are rated appropriately and set up to take
measurements of this magnitude.
13.
Locate and flip the display lid upwards.
14.
Turn the heater on, by pressing the ON/OFF toggle
switch on the front display.
15.
Set the mode to either SPA or POOL. For installations
utilizing the Raypak Expanded Function Board refer
to the installation and set up instructions "Installer
Setup Mode" on page 29 to set up the pump, valve
and auxiliary functions prior to firing the heater.
16.
If the set point is higher than the current temperature,
the heater will begin its startup sequence.
17.
The ignition control will verify that the blower relay
is open before starting the blower. Once proven
open, the blower will be powered to start the ignition
sequence.
18. Once the blower relay proves, a 45 second pre-purge
period will begin to purge the combustion chamber.
19. Once the pre-purge period ends, the igniter will begin
to spark just prior to the gas valve opening. The gas
valve will open for a 4 second trial for ignition. If
flame is proven, the heater will operate to meet heat
demand.
If flame is not proven, the 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 35 for adjusting the
valve manifold pressure if the reading is not within
tolerance.
