Supply water piping

r

Do not use PVC, iron, or any piping which has been

treated with chromates, boiler seal or other chemicals.

r

Mount a check valve and a shut off valve (near the inlet).

comfortably, 98.1 to 491 kPa (14 to 70 PSI) of

pressure is needed from the water supply.

Be sure to check the water pressure. If the

water pressure is low, the water heater cannot

perform to its full capability, and may become

a source of trouble for the client.

If necessary, provide drain piping or use a

drain hose to remove the water.

Try to make the piping as short as possible.

ensure that the supply water pressure to the

inlet of the heater does not fall below 29 PSI when

the maximum amount of water is being demanded.

Also install a pressure meter on the inlet. If this is

not done, local boiling will occur inside the water

heater causing abnormal sounds and decreasing

the durability of the heat exchanger.

is below -30°F (-35°C).

When combustion air is supplied from the indoors, the room temperature must be greater than

32°F

(0°C)

to prevent freezing and the room inside must not have negative pressure.

freeze protection measures, refer to the Use and Care Manual.
