full of water (77 lbs).
2. The installation area must provide adequate clearances for removal of the front panel and servicing the
unit.
3. Drill two 13/32 inch holes in the masonry wall.
NOTE: The holes must be level and at least 3-1/2 inches deep.
4. Insert the masonry wall anchors into the drilled holes. Place the wall bracket over the anchors and screw
the two Phillips head screws tight against the bracket.
WATER PIPING
HOT 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 Injury
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 disabled. 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 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 should be used at the hot water taps used
by these people or at the water heater. 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 components used with a non potable water
heating appliance.
Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.
Water supply system may, because of such events as high line pressure, frequent cut-offs, the effects of water
hammer among others, have installed devices such as pressure reducing valves, check valves, back flow
preventers, etc. to control these types of problems. When these devices are not equipped with an Internal by-
pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated,
It expands(thermal expansion) and closed systems do not allow for the expansion of heated water.
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 temperature-pressure relief valve is reached, the valve will relieve
the excess pressure. The temperature-pressure relief valve is not limited for the constant relief of thermal
expansion. This is an unacceptable condition and must be corrected.
It is recommended that any devices installed which could create a closed system have a by-pass and/or the
system have an expansion tank or device to relieve the pressure built by thermal expansion in the water
system. Expansion tanks are available for ordering through a local plumbing contractor. Contact the local water
supplier and/or a service agency for assistance In controlling these situations.
