Mounting the Water Heater
CAUTION: Reinforcement of the wall is required in case the wall is not strong enough to hold the appliance.

Make sure the location of the appliance allows for easy access and operation.
Wall studs should be utilized when mounting the water heater to the wall. Alternately, a suitable piece of wood may be placed inside or outside of the wall to span the distance between the wall studs. Fasten the water heater mounting brackets to the wood.
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 10 feet (3 m), (Indoor water heater only.)
Install a wood screw for the upper bracket with a clearance of 1/8” (.32 cm) between the wall and the screw head. Hang the center of the upper bracket on the screw.
Using a wood screw and a washer, affix the lower bracket to the wall (Left and Right). Repeat to affix the top bracket.
The brackets can be adjusted to change the distance between the back of the appliance and the wall within the range of 3/8” (.95 cm) to 1½” (3.8 cm).
Loosen the adjustment screws of both the top and the bottom brackets to adjust the distance. (See diagram below)

IMPORTANT: Do not apply heat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to adapter before fitting adapter to the water connections on heater. Any heat applied to the water supply fittings will permanently damage the internal components of the water heater.
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 (0°C), but not exceeding 140°F (60°C).
●Free of lime and scale deposits.
●DO NOT reverse the hot and cold water connections. The water heater will not operate.
Water Supply Connections
Plumbing should be carried out by a qualified plumber in accordance with local codes.
Use approved plumbing materials only.
The diameter of the pipe lines should be a minimum of 3/4”.
To conserve energy and to prevent freezing, insulate both cold and hot water supply lines. DO NOT cover the drain or pressure relief valve.
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 (97 kPa) and a minimum water flow rate of 0.66 gpm (2.5 lpm).
●A water pressure of 40 psi (276 kPa) is required to achieve maximum flow rate.
●To maintain proper performance, ensure sufficient water supply pressure. The Required Water Pressure = Min. Operating Water Pressure
(14 psi) (97 kPa) + Pipe Pressure Loss + Faucet and Shower Pressure Loss + Safety Margin (more than 5 psi)
(34 kPa).
●To supply hot water to upper floors,
additional water pressure (0.44 psi/ft) (10 kPa/m) 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 to ensure a minimum system pressure of 40 psi (276 kPa).
●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.
Notice: If multiple water heaters are installed in a manifold system, the water piping must be in “Parallel”. A water pressure of 40 psi (276 kPa) is recommended for each water heater for proper operation of the water heaters.
