On-Demand Water Heater Installation Manual and Owner’s Guide
A pressure relief valve listed as complying with the standard for Relief Valve and Automatic Gas Shutoff
Devices for Hot Water Supply System, ANSI Z21.22 • CSA 4.4, shall be installed at the time of installation of
the water heater in the location specified by the manufacturer. Local codes shall govern the installation of
relief devices for safety operation of the water heater. The relief valve must not be removed or plugged.
No valve shall be placed between the relief valve and the water heater. The relief from the discharge of
the pressure relief valve shall be disposed of in a suitable place where it will cause no damage. Also, there
shall be no other reducing coupling or other restrictions installed on the discharge line to restrict flow.
See Installation Manual heading “PRESSURE RELIEF VALVES” for installation and maintenance of relief
valve discharge line and other safety precautions.
Vapors from flammable liquids will explode and catch fire causing death or severe burns.
Do not use or store flammable products such as gasoline, solvents or adhesives in the same room or
area near the water heater.
Keep flammable products:
1. Far away from heater.
2. In approved containers.
3. Tightly closed and
4. Out of reach of children.
Vapors:
1. Cannot be seen.
2. Are heavier than air.
3.
Go a long way on the floor.
4. Can be carried from other rooms to
the main burner by air currents.
Installation: Do not install water heater where flammable products will be stored or used unless the main burner is
at least 18” (457 mm) above the floor. This will reduce, but not eliminate the risk of vapors being ignited by
the main burner.
Read and follow water heater warnings and instructions. If the owner’s manual is missing, contact
the retailer or manufacturer.
