1.When directly communicating with the outdoors, each open- ing shall have a minimum free area of 1 square inch per 4,000 BTU per hour of total input rating of all equipment in the enclosure. (See Figure 7.)
2.When communicating with the outdoors through vertical ducts, each opening shall have a minimum free area of 1
square inch per 4,000 _TU per hour of total input rating of all equipment in the enclosure. (See Figure 8.)

5.Louvers and Grilles: In calculating free area, consideration shall be given to the blocking effect of louvers, grilles or screens protecting openings. Screens used shall not he smaller than ¼ inch mesh. If the free area through a design of louver or grille is known, it should be used in calculating the size opening required to provide the free area specified. If the design and free area is not known, it may be assumed that wood louvers will be
the equipment so that they are opened automatically during equipment operation.
6.Special Conditions Created by Mechanical Exhausting or
Fireplaces: Operation of exhaust fans, ventilation systems clomes dryers or fireplaces may create conditions requiring special attention to avoid unsatisfactory operation of installed gas utilization equipment.
Water Piping
_WARNING
HOTTER WATER CAN SCALD: Water heaters are intended to >reduce hot water. Water heated to a temperature which will satisfy'clotheswashing, dishwashing, and other sanitizing needs can scald and permanently injure you upon contact. Some peo- )le are more likely to be permanently injured by hot water than others. These include the elderly, children,the infirm, or pbysical- ly/mentally handicapped. If anyone usinghot water in your home fits into one of these groups or if there is a localcode or state law requiring a certain temperature water at the hot water tap, then _u must take special precautions. In addition to usingthe lowest )ossibletemperature setting that satisfies your hot water needs, a means suchas a mixing valve, shouldbe used at the hot water taps used by these people or at the water heater. Mixing valves are availableat plumbing supplyor hardware stores. Follow man- ufacturers instructions for installation of the valves, Before changing the factory setting on the thermostat, read the "Temperature Regulation" section in this manual.

lfa water heater is installed in a closed water supply system; such as one having a
check valve, etc.., in the cold water supply; means shall be provided to control thermal expansion. Contact the local utility or local Sears Service Center on how to control this situation.
NOTE: To _protect against untimely corrosion of hot and
cold water fittings, it is strongly recommended that
tric unions or couplings be installed on this water heater when connected to copper pipe.
NOTE: If using copper tubing, solder tubing to an adapter before attaching the adaptor to the cold water inlet connection,
Do not solder the cold water supply line dlrecdy to the cold water inlet. It will harm the dip tube and damage the tank.
