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).

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.

L. Pool Heater Pump - Refer to Equipment Schedule
M. SureRack™ Pool heater Stacking Kit
1. The pool heaters shall be stacked directly one on top of the other, without offset, to minimize
footprint.
2. The stacked pool heaters shall be factory-certified to Seismic Zone 4 requirements.
N. Manual Bypass
1. The heater shall be equipped with an external bronze pump and bypass arrangement designed
to maintain the water entering the heater at the proper temperature that will prevent
condensation and scale in the heat exchanger. The entire waterway shall be non-ferrous.
O. Cold Water Run System
1. The pool heater(s) shall be configured with a cold water run automatic proportional by-pass
system that ensures the pool heater will experience inlet temperatures in excess of 105ºF in
less than 7 minutes to avoid damaging condensation. The unit will automatically shut down if
the inlet temperature is not achieved within the 7 minute time frame.
2. The cold water run system shall be configured with a variable speed pump that is controlled by
a system-matched PID control that injects the correct amount of cold water directly into the -
pool heater loop to maintain a minimum inlet temperature. The PID controller temperature
sensor shall be located in the inlet header of the pool heater.
3. The control shall have a temperature setting dial located on the face of the board. The
temperature range of the dial shall be 105ºF to 120ºF. The PID Logic shall be capable of
limiting system overshoot to a maximum of 10ºF on initial start-up or call-for-heat.
4. The cold water run system shall be completely wired and mounted at the factory.
5. The control shall have the following diagnostic LED’s:
a. Call for heat
b. Start-up mode
c. Inlet temperature error
d. Sensor out of range
6. The controller shall have the capability to add optional alarm contacts
P. Low Gas Supply Pressure Manifold
1. The pool heater(s) shall be CSA-certified for full-input operation down to 4.0 inches W.C.
dynamic inlet gas supply pressure.
Q. FlexGas™ Dual-Fuel Gas Manifold
1. The pool heater(s) shall be configured with a patented, CSA-certified gas control system that
is capable of operating with natural gas or propane gas in a configuration that does not require
mechanical disassembly or adjustment of gas or air components.
a. The gas switching shall be accomplished by a keyed three-position electrical switch with an
“OFF” position between the Natural and Propane settings including a positive fuel
shutdown in both directions to block back-pressure.
b. The FlexGas manifold shall as a minimum have two ON/OFF solenoid shutoff valves for
natural gas, and a minimum of one ON/OFF solenoid shutoff valve and a lock-up regulator
for propane gas, as a safety feature.
c. The FlexGas manifold shall be capable of accomplishing the fuel changeover in less than
sixty seconds.
R. TruSeal™ Direct Vent
1. The pool heater(s) shall meet safety standards for direct vent equipment as noted by the 2006
UMC, section 1107.6, ASHRAE 15-1994, section 8.13.6, and ANSI Z21.10.3.
2.3
SOURCE QUALITY CONTROL
A. The pool heater(s) shall be completely assembled, wired, and fire-tested prior to shipment from the
factory.
B. The pool heater(s) shall be furnished with the sales order, ASME Manufacturer’s Data Report,
inspection sheet, wiring diagram, rating plate and Installation and Operating Manual.
