• Well water systems should be set at a range of
50-60 psi.
• When the water is supplied from a water
supply tank, the height of the tank and the
diameter of the pipes and their relation
to water pressure, should be taken into
consideration. Gravity
water pressure is not
recommended.

will fail to ignite. Keep the shower head clean from
debris that could cause additional pressure drop.
NOTICE:
If using mixing valves on the outlet,
choose one which prevents cold water pressure
from overcoming hot water line pressure.
IMPORTANT:
Do not apply heat to the HOT or
COLD water connections. Any heat applied to the

followed:
• Operation of the water heater requires the
minimum water pressure of 14 psi and a

Mounting the 20H Outdoor Tankless Water
Heater
Make sure the location of the water heater allows for easy access and operation. The water
heater should be located in an area where leakage of the tank or connections will not result

In case of dry wall or concrete wall use dry wall anchors or lag bolts.
The water heater requires 120VAC/ 60Hz. Have a receptacle with ground terminal near the
water heater. The length of the power supply cord is 5 feet.

Hang up the water heater unit, tighten the expansion screws, and put 2 wood thread screws
into the bottom holes.
When being installed directly on carpeting, the water heater shall be installed on a metal or
