Pennant Pool Heater

Page 17

If a call for heat is prevented from being satisfied

either by a safety interlock or due to an ignition
lockout, the red “Service” indicator on the front panel
will light. To reset the standard ignition module,
toggle the Pennant power switch off, and then on
again. (To reset the optional single try lockout ignition
module, the reset button on the module must be
pressed. Interrupting power to this module will not
reset the lockout.)

The Pennant 1250, 1500, 1750 and 2000 models

have two ignition modules that control different
burners.

6.2 Filling the Heater System

1.

Ensure the system is fully connected, filled with
water and all valves are open.

2.

Start up heater according to the procedure in this
manual. Operate the entire system for one (1) hour.

3.

After placing the unit in operation, the ignition
system safety shutoff device must be tested.
First, shut off the manual gas valve, and call the
unit for heat. After the pre-purge and ignitor
heat-up time, the main gas terminals will be
energized, attempting to light, for four (4)
seconds, and then will de-energize. The unit will
go into lockout mode. Second, turn the power off
and then on again, push the reset button (optional
Ignition Module only), open the manual gas
valve and allow the unit to light. While the unit
is operating, close the manual gas valve and
ensure that power to the main gas valve no
longer exists.

4.

Check the entire system for leaks.

Caution

Protect the heater from low pH water if an “acid
start up” or similar technique is used. Corrosion of
the heater and heat exchanger due to low pH water
is not covered under the limited warranty. The water
must be neutralized to normal pH levels before
filling the heater and starting up the system.

Important:

 The installer is responsible for identifying

to the owner/operator the location of all emergency
shutoff devices.

 WARNING

Do not use this appliance if any part has been
under water. Immediately call a qualified service
technician to inspect the appliance and to replace
any part of the control system and any gas control
that may have been under water.

6.3 Operating the Burner and Set Up

6.3.1 Set Up for 0 to 2500 Feet Altitude

The setup must be checked before the unit is put

in operation. Problems such as failure to start, rough

ignition, strong exhaust odors, etc. can be due to
improper setup. Damage to the heater resulting from
improper setup is not covered by the limited warranty.
1.

Using this manual, make sure the installation is
complete and fully in compliance with the
instructions.

2.

Determine that the appliance and system are
filled with water and all air has been bled from
both. Open all valves.

3.

Observe all warnings on the Operating
Instructions label and turn on gas and electrical
power to appliance.

4.

Switch on the appliance power switch located on
the right side of the unit.

5.

The Pennant will enter the start sequence, as long
as the unit is being called for heat. The blower
and pump come on for pre-purge, then the ignitor
warm-up sequence starts and after the ignitor
warm-up is complete and all safety devices are
verified, the gas valves open. If ignition doesn’t
occur, check that there is proper gas supply. Wait
5 minutes and start the unit again. During initial
start up, air in the gas line may cause the Pennant
to "lock out" during the first few trials for
ignition.  Depending on the ignition modules
installed, the manual reset button on the ignition
module(s) may need to be depressed to restart the
heater.

6.

When the unit is running, the supply gas pressure
must be checked. Inlet gas pressure must not
exceed 13" W.C. (3.2kPa). The minimum inlet
gas pressure is 5" W.C. (1.2kPa).

7.

Once the inlet gas pressure is verified, the outlet
gas pressure from each valve (manifold gas
pressure) must be checked, and adjusted, if
necessary. The manifold gas pressure must be
2.5" W.C. (0.62kPa).

8.

Complete the setup by checking the CO

2

 at the

outlet of the unit. The CO

2

 should be 8% for

natural gas, or 9.2% for propane.

9.

After placing the appliance in operation, the
Burner Safety Shutoff Device must be tested

.

To test:
(a)

Close gas shutoff valve with burner
operating.

(b)

The flame will go out and blower will
continue to run for the post purge cycle.
Three (3) additional attempts to light will
follow (only one (1) attempt for optional
module). Ignition will not occur as the gas
is off. The ignition control will lockout, and
will have to be reset before the unit will
operate. The ignition control reset button is
located on each ignition control, in the
lower right corner, and can be reset by
depressing. It is not marked on the ignition
control label.

(c)

Open gas shutoff valve. Restart the
appliance. The ignition sequence will start
