Insulation Blankets; Hard Water - Lochinvar LTN07575 Instruction Manual

If this water heater will be used in beauty shops, barber
shops, cleaning establishments, or self-service laundries
with dry cleaning equipment, it is imperative that the
water heater or water heaters be installed so that
combustion and ventilation air be taken from outside
these areas.
Propellants of aerosol sprays and volatile compounds,
(cleaners, chlorine based chemicals, refrigerants, etc.)
in addition to being highly flammable in many cases, will
also change to corrosive hydrochloric acid when exposed
to the combustion products of the water heater. The
results can be hazardous, and also cause product failure.

INSULATION BLANKETS

Breathing Hazard - Carbon Monoxide Gas
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.
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
(page 31) for identification of components
Test Points
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. See
Figure 16
• DO NOT cover the thermostat or the temperature-
pressure relief valve.
• DO NOT allow the insulation to come within 2 inches
(5 cm) of the floor to prevent blockage of combustion
air flow to the burner.
• 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 the
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.
