associated with constant pump operation.
G. Firing
Mode
1. For all models, provide on-off firing control of the gas input to the pool heater.
H. Pool
Heater
Diagnostics
1. Provide external LED panel displaying the following pool heater status/faults:
a. Power on - Blue
b. Call for heat – Amber
c. Flow - Green
d. Stages 1,2, 3 and 4 – Green
e. Fans 1, 2, and 3 proven - Green
f. Ignition fault - Red
g. Safety fault - Red
2. Provide internal circuit board with fault history indicating the following safety faults by LED
signal:
a. System enabled
b. Manual reset hi-limit
c. Blocked vent switch
d. Air pressure switch
e. Flow switch
f. Ignition
lock-out
g. Low gas pressure switch
Specifier Note: The following items are options. Delete if not being specified.
h. Auto reset high limit
i. Low water cut-off
j. High gas pressure switch
3. A Central Point Wiring board with diagnostic LED’s indicating the status of each relay.
4. Provide ignition module indicating the following flash codes by LED signal:
a. 1 flash – low air pressure
b. 2 flashes – flame in the combustion chamber w/o CFH
c. 3 flashes – ignition lock-out (flame failure)
d. 4 flashes – low hot surface igniter current
e. 5 flashes – low 24VAC
f. 6 flashes – internal fault (replace module)
I.
Combustion Chamber: The lightweight, high temperature, multi-piece, interlocking ceramic fiber
combustion chamber liner shall be sealed to reduce standby radiation losses, reducing jacket
losses and increasing unit efficiency.
J. Venting
1. When routed vertically, the pool heater’s flue material and size shall be in accordance with the
National Fuel Gas Code, ANSI Z223.1/NFPA54 latest edition (Category I).
2. When routed horizontally, the pool heater’s flue material and size shall meet or exceed the
requirements as specified for Category III in the National Fuel Gas Code, ANSI Z223.1/NFPA
54 latest edition.
3. The pool heater(s) shall be ducted combustion air ready.
K. Cabinet
1. The corrosion-resistant galvanized steel jackets shall be finished with a baked-on epoxy
powder coat, which is suitable for outdoor installation, applied prior to assembly for complete
coverage, and shall incorporate louvers in the outer panels to divert air past heated surfaces.
2. The pool heater(s), if located on a combustible floor, shall not require a separate combustible
floor base.
3. The pool heater(s) shall have the option of venting the flue products either through the top or
the back of the unit.
4. Combustion air intake shall be on the left side of the cabinet, right side optional.
Specifier Note: The remaining items in this section are options. Delete those that are not being
specified. The Low Gas Supply Pressure and FlexGas Manifolds also cannot be used
on the same boiler.
