insulation blanket
Do not obstruct water heater air intake
with insulating blanket.
Gas and carbon monoxide detectors
are available.
Install water heater in accordance with
the instruction manual.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
Breathing Hazard - Carbon Monoxide Gas
Insulation blankets are available to the general public for external
use on gas water heaters but are not necessary with these
products. The purpose of an insulation blanket is to reduce the
standby heat loss encountered with storage tank heaters. The
water heaters covered by this manual meet or exceed the energy
Policy Act standards with respect to insulation and standby heat
loss requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this
heater, you should follow these instructions. See the features
and Components section of this manual for identification of
components mentioned below. failure to follow these instructions
can restrict the air flow required for proper combustion, potentially
resulting in fire, asphyxiation, serious personal injury or death.
• do not apply insulation to the top of the water heater, as
this will interfere with safe operation of the draft hood.
• do not cover the gas valve, thermostat or the Temperature-
Pressure relief Valve.
• do not allow insulation to come within 2” (5 cm) of the
burners, to prevent blockage of combustion air flow to the
burners.
• do not allow insulation to come within 9 inches (23 cm)
of floor, (within 2 inches (5 cm) of bottom cover) to prevent
blockage of combustion air flow to the burners..
• do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
• do obtain new warning and instruction labels from the
manufacturer for placement on the blanket directly over the
existing labels.
• do inspect the insulation blanket frequently to make certain
it does not sag, thereby obstructing combustion air flow.
hard water
Where hard water conditions exist, water softening or the
threshold type of water treatment is recommended. This will
protect the dishwashers, coffee urns, water heaters, water piping
and other equipment.
See the maintenance Section in this manual for sediment and
lime scale removal procedures.
circulation pumps
A circulating pump is used when a system requires a circulating
loop or there is a storage tank used in conjunction with the water
heater. See Water Piping Diagrams in this manual for installation
location of circulating pumps.
See the Circulation Pump Wiring Diagrams in this manual for
electrical hookup information. Install in accordance with the
current edition of the National electrical Code, NfPA 70 or the
Canadian electrical Code, CSA C22.1.
All-bronze circulators are recommended for used with commercial
water heaters.
