NOTICE
This is a gas appliance and should be installed
by a licensed electrician and/or certified gas
supplier. Service must be performed by a
qualified service installer, service agency or
the gas supplier.
ƽ WARNING
If the information in these instructions is
not followed exactly, a fire or explosion may
result causing property damage, personal
injury, or death.
This appliance MUST NOT be installed in
any location where gasoline or flammable
vapors are likely to be present, unless the
installation is such to eliminate the probable
ignition of gasoline or flammable vapors.
Warranty –
Factory warranty (shipped with unit) does not apply to units
improperly installed or improperly operated.
Experience has shown that improper installation or system
design, rather than faulty equipment, is the cause of most
operating problems.
1. Excessive water hardness causing a lime/scale build-up in
the copper tube is not the fault of the equipment and is
not covered under the manufacturer’s warranty (see
Water Treatment and Water Chemistry).
2. Excessive pitting and erosion on the inside of the copper
tube may be caused by too much water velocity through
the tubes and is not covered by the manufacturer’s
warranty (see Pool heater Flow Rates and Temperature Rise
for flow requirements).
Checking equipment –
Upon receiving equipment, check for signs of shipping damage.
Pay particular attention to parts accompanying the appliances
which may show signs of being hit or otherwise being
mishandled. Verify total number of pieces shown on packing
slip with those actually received. In case there is damage or a
shortage, immediately notify the carrier.
Do not use this appliance if any part has been under water.
The possible damage to a flooded appliance can be extensive
and present numerous safety hazards. Any appliance that has
been under water must be replaced.
ƽ WARNING
Improper installation, adjustment,
alteration, service or maintenance can
cause injury or property damage. Refer
to this manual for assistance or additional
information, consult a qualified installer,
service agency or the gas supplier.
Special instructions
REMOVAL OF COMBUSTION CHAMBER LINING OR
BASE PANELS:
Avoid breathing dust and contact with skin and eyes.
• Use NIOSH certified dust respirator (N95). This type of
respirator is based on the OSHA requirements for
cristobalite at the time this document was written. Other
types of respirators may be needed depending on the
job site conditions. Current NIOSH recommendations
can be found on the NIOSH website at
http://www.cdc.gov/niosh/homepage.html.
NIOSH approved respirators, manufacturers, and phone
numbers are also listed on this website.
• Wear long-sleeved, loose fitting clothing, gloves, and eye
protection.
The ceramic fiber material used in this
appliance is an irritant; when handling or
replacing the ceramic materials it is advisable
that the installer follow these safety guides.
NOTICE
ƽ WARNING
The combustion chamber insulation in this
appliance contains ceramic fiber material.
Ceramic fibers can be converted to cristobalite
in very high temperature applications.
The International Agency for Research on
Cancer (IARC) has concluded, “Crystalline
silica in the form of quartz or cristobalite
from occupational sources is carcinogenic
to humans (Group 1).” Normal operating
temperatures in this appliance are below the
level to convert ceramic fibers to cristobalite.
Abnormal operating conditions would have
to be created to convert the ceramic fibers in
this appliance to cristobalite.
The ceramic fiber material used in this
appliance is an irritant; when handling
or replacing the ceramic materials it is
advisable that the installer follow these safety
guidelines.
Apply enough water to the combustion chamber
lining to prevent airborne dust.
Remove the combustion chamber lining from the
appliance and place it in a plastic bag for disposal.
• NIOSH stated First Aid:
Eye: Irrigate immediately.
Breathing: Fresh air.
