NOTE: OBTAIN ALL APPLICABLE PERMITS AND OBEY ALL LOCAL CODES.

NOTE: Install all system components and piping in such a manner that does not reduce the performance of any fire rated assembly.

DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN UNDERWATER. Immediately call a qualified service technician.

Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee.

B. WHEN SERVICING THE WATER HEATING SYSTEM

 To avoid electric shock, disconnect electrical supply before performing maintenance.

 To avoid severe burns, allow water heater and associated equipment to cool before servicing.

C. HEATER WATER

 Do not use petroleum-based cleaning or sealing compounds in a water heating system. Gaskets and seals in the system may

be damaged. This can result in substantial property damage.

 Do not use “homemade cures” or “heater patent medicines”. Damage to heater, substantial property damage, and/or serious

personal injury may result.

NOTICE FOR SINGLE-WALL HEAT EXCHANGER MODELS

Per the Uniform Plumbing Code:

Single-wall heat exchangers are permitted if they satisfy all of the following requirements:

1. The heat transfer medium is potable water or contains only substances which are recognized as safe by the U.S. Food and

Drug Administration (FDA).

2. The pressure of the heat transfer medium is maintained less than the normal minimum operating pressure of the potable water

system (steam systems must comply with this statement).

3. The equipment is permanently labeled to indicate that only additives recognized as safe by the FDA shall be used as the heat

transfer medium.

Other heat exchanger designs may be permitted where approved by the Administrative Authority.

D. FREEZE PROTECTION

NOTE: Consider piping and installation when determining heater location. Place water heater as close to the boiler as possible, in a

location not prone to freezing.

Failure of the water heater due to freeze related damage IS NOT covered by warranty.

In water heaters with single wall heat exchangers, the heat transfer fluid must be water or nontoxic food grade glycol, FDA rated

“generally recognized as safe” (GRAS) and having a toxicity rating or class of 1, as listed in Clinical Toxicology of Commercial

Products, 5

edition. Ensure the system is permanently labeled to indicate any additives used in the heat transfer fluid.

NEVER use any toxic chemical, including automotive, standard glycol antifreeze, or ethylene glycol made for hydronic (non-potable)

systems. These chemicals can attack gaskets and seals in water systems, are poisonous if consumed, and can cause injury or death.

E. CHEMICAL VAPOR CORROSION

NOTE: DAMAGE TO THE WATER HEATER OR RELATED COMPONENTS CAUSED BY EXPOSURE TO CORROSIVE VAPORS

IS NOT COVERED BY WARRANTY. The limited warranty is voided when failure of water tank is due to a corrosive atmosphere. (Refer

to the limited warranty for complete terms and conditions).
