Mounting the Water Heater
Mounting to the wall
To mount the water heater to the wall:
1
Check that the wall is level and can support the weight of the water heater.
2
Affix the mounting bracket securely to the wall.
3
Align the grooves on the back of the water heater with the tongues on the
mounting bracket and hang the water heater from the bracket.
Connecting the Gas Supply
1
Connect the gas supply line.
2
Check for gas leaks at all joints.
Notice
•
Tighten the water heater connection valves with care to avoid damage.
•
Apply gas leak detection solution to all gas fittings.
•
The minimum internal diameter required for any appliance connector is ¾ ”.
•
When using flexible gas lines, ensure that the pipe’s inner diameter and connector is
sufficient to supply the required BTUs. Also, ensure that the flexible line has no crimps
or tight bends in it, as this will restrict gas flow.
•
To facilitate any future maintenance or service, the installation of a union on the gas
supply line close to the water heater is recommended.
Connecting the Water Supply
•
The following is a water piping example for the water heater:
Warning
Make sure to install a mixing/tempering valve in your water system in order
to protect against injury. When it is required by your local plumbing code or
regulation, you must install a mixing/tempering valve accordingly.

Connecting the Pressure Relief Valve
Warning
Improper installation of the pressure relief valve may result in property damage,
personal injury, or death. Follow all instructions and guidelines when installing
the pressure relief valve. Only a licensed professional should install the valve.
Caution
The pressure relief valve must conform to the current edition of ANSI Z21.22 or
CAN 1-4.4 and installation must follow local codes.
This water heater does not come with an approved pressure relief valve. To complete
the installation of the water heater, you must install an approved 3/4”, maximum 150 PSI
pressure relief valve on the pressure relief valve connector.

Notice
In recirculating system, install the pressure relief valve on the hot water outlet. The
pressure relief valve should be placed as close to the water heater as possible. No other
valve should be placed between the pressure relief valve and the water heater.
