DANGER
THERE ARE NO USER SERVICABLE PARTS ON THIS BOILER. ATTEMPTS TO
SERVICE THIS BOILER BY SOMEONE OTHER THAN A QUALIFIED GAS SER­VICE TECHNICIAN COULD VOID THE WARRANTY, CAUSE PROPERTY
DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.

• Do not use this boiler if any part has been under water. Immediately call a qualied service technician

to inspect the boiler and to replace any part of the control system and any gas control which has been
under water.

• Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical

supply to the pump. Instead shut off the gas supply at a location external to the appliance/En cas de
surchauffe ou si l’admission de gaz ne peut étre coupée, ne pas couper ni débrancher l’alimentation
électrique de la pompe. Fermer plutot le robinet d’admission de gaz à l’extérieur de l’appareil.

• This boiler may have parts containing refractory ceramic bers (RCF). See the safety information on

page 11 if this boiler must be serviced or repaired.

CAUTION

Like all central heating appliances, this boiler is equipped with safety devices, which could cause it to shutdown,
requiring service to restore normal operation. Where such a shutdown could result in damage from low temperatures
(such as frozen pipes), do not leave the heating system unattended during cold weather unless alarms or other safe­guards are in place to prevent damage.

1) This manual covers the proper care and use of the following boilers:

• AWR “Aruba IV” series gas water boiler

• CWI “Cayman” series gas water boiler

• BWF “Bali” series fan assisted water boiler

• CWD “Cabo2” series gas direct vent water boiler

• BWC “Bimini” series gas condensing direct vent water boiler

• BSI “Bermuda” series gas steam boiler

Most of the information in this manual applies to all of the above boilers. Information that is unique to a par­ticular series is clearly marked with the series to which it applies.

2) Instructions to safely light and shut down this boiler are shown on pages 5 - 7, as well as on a label af­xed to the boiler.

WARNING



• In the event that the ame rollout switch opens, the cause of the ame rollout must be diagnosed and cor-

rected by a qualied gas service technician before the boiler is restarted.

• In the event that the ignition system on a CWD or BWC does not permit the boiler to re, there is either
a problem with the igntion system, an occurrence of ame rollout, or a problem with the vent system.
Call a qualied gas service technician to diagnose and correct the problem.

• A “tripped” rollout switch must be replaced by an identical switch having the same temperature setting.

Figure 2: Blocked Vent SwitchFigure 1: Flame Rollout Switch

WARNING

A shutdown of the burners due to the blocked vent switch is an indication that there is a problem with the vent system,
such as a blockage. The blocked vent switch should only be reset after a qualied gas service technician has diagnosed
and corrected the venting problem that caused the blocked vent switch to open.

3) All boilers except the CWD and BWC boilers are equipped with a ame rollout switch (Figure 1). This
switch will shut the burners down in the event that ames exit the burner compartment through the front
opening. The CWD and BWC use an electronic means built into the ignition system to extinguish the
burner/s in the event that ames exit the combustion chamber. If the boiler fails to re, call a qualied
heating service agency to diagnose and correct the problem.

4) The AWR, CWI and BSI boilers are equipped with a blocked vent shut-off switch (Figure 2). This switch
will shut the boiler down in the event that there is an excessive blockage in the vent system. This switch
has a reset button, which must be pressed before the boiler can be restarted.

5) BWF, CWD, BWC Series boilers – These boilers are equipped with a safety feature which will shut
down the burners in the event that there is a blockage in the vent system. In the event that the boiler fails
to function, and the boiler is vented through an outside wall accessible from the ground, inspect the vent
terminal on the outside wall for a blockage such as a bee’s nest or ice. If a blockage is found, the burners
should ignite approximately 30 seconds after the blockage is removed. If no blockage is found, or if the
terminal is inaccessible from the ground, the problem must be diagnosed and corrected by a qualied gas
service technician.

Maintenance

1) Safe reliable operation of this boiler depends upon proper periodic maintenance.

2) The following should be done on a continuous basis:

• Keep the area around the boiler free of objects, which are ammable or which could obstruct the

ow of air into and around the boiler.
