Mounting the SH22 Water Heater
CAUTION: Reinforcement of the wall is required in case the wall is not strong enough to hold the water heater.
Water Supply Connections
Plumbing should be carried out by a qualified
plumber in accordance with local codes.
Use approved plumbing materials and tools only.
To conserve energy and to prevent freezing, insulate
both cold and hot water supply lines. DO NOT cover
the drain valves.
To ensure proper operation of the water heater,
the following water pressure guidelines should be
followed:
• Operation of the water heater requires the
minimum water pressure of 14 psi and a
minimum water flow rate of 0.75 gpm.
• Additional water pressure is required for
long pipe runs and outlet fitting(s) water
pressure drops.
• To maintain proper performance, ensure
sufficient water supply pressure. The
Required Water Pressure = Min. Operating
Water Pressure (14 psi) + Pipe Pressure
Loss + Faucet and Shower Pressure Loss +
Safety Margin (more than 5 psi).
CAUTION: This water heater must only be used with the following water supply system conditions:
• With clean, potable water free of corrosive chemicals, sand, dirt, or other contaminates.
• With inlet water temperatures above 32°F, but not exceeding 120°F.
• Free of lime and scale deposits.
• DO NOT reverse the hot and cold water connections. The water heater will not operate.

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 damage to the area adjacent to the water
heater or to lower floors of the structure. When such locations cannot be avoided,
it is recommended that a suitable drain pan, adequately drained, be installed
under the appliance. The pan must not restrict combustion air flow.
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.
Drill the holes as per the sizes in the figure to the left, put 2 expansion screws into
the top holes, and 2 rubber screws into the bottom holes.
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 wood panel extending beyond the full width and depth of the water
heater by at least 3 in (76.2 mm) in any direction, or if the water heater is installed
in an alcove or closet, the entire floor shall be covered by the panel. The panel
must be strong enough to carry the weight of the heater when full of water.
• To supply hot water to upper floors,
additional water pressure (0.44 psi/ft)
must be ensured.The measurement should
be calculated by the distance between the
water inlet of the water heater (ground
level) to the hot water faucet (upper floor level).
• 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.
NOTICE: If the water flow resistance of a
shower head is too high, the burner in the water
heater 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
water supply fittings will permanently damage the
internal components of the water heater.
