CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY OCCUR IF AIRFORCOMBUSTIONCONTAINSCERTAINCHEMICALVAPORS.SUCH CORROSION MAY RESULT IN FAILUREAND RISK OF ASPHYXIATION.
Spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride (water softener salt), waxes, and process chemicals are typical compounds which are potentially corrosive.
Do not store products of this sort near the heater. Also, air which is brought in contact with the heater should not contain any of these chemicals. If necessary, uncontaminated air should be obtained from remote or outside sources. The limited warranty is voided when failure of water heater is due to a corrosive atmosphere. (See limited warranty for complete terms and conditions).
WATER PIPING
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, cleaning and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a *mixing valve, shall be used at the hot water taps used by these people or at the water heater, see Figure 2. Valves for reducing point of use temperature by mixing cold and hot water are also available:
Consult a Qualified Installer or Service Agency. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.
This water heater shall not be connected to any heating systems or component(s) used with a
All piping components connected to this unit for space heating applications shall be suitable for use with potable water.
Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.
When the system requires water for space heating at temperatures higher than required for domestic water purposes, a tempering valve must be installed. Please refer to Figure 2 for suggested piping arrangement.
Water supply systems may, because of such events as high line pressure, frequent
The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s
