† Depending on the installed equivalent length, and/or the number of appliances connected, the
supply gas line size may have to be increased beyond the minimum required sizes - see Gas
8. Locate the water heater where an adequate supply of fresh
air for combustion and ventilation can be obtained. See Air
9. Locate the water heater where the vent and intake air piping,
when installed, will remain within the maximum equivalent
lengths allowed. See Venting requirements on page 24.
10. Do not locate the water heater where noise (such as
the Combustion blower) during normal operation will be
objectionable in adjacent areas.
11. Do not locate the water heater where the subsequent
installation of the vent (exhaust) or intake air terminations
would be objectionable due to noise at the termination(s).
This includes locations close to or across from windows and
doors. See Venting installation on page 22.
Fire or Explosion Hazard
Read instruction manual before
installing, using or servicing
water heater.
Avoid all ignition sources if you smell gas.
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
Use only the gas shown on the water heater rating label.
Keep ignition sources away from faucets after extended
periods of non-use.
Maintain required clearances to combustibles.
Do not expose water heater controls to excessive gas
pressure.
locating the water heater
Carefully choose a location for the new water heater. The
placement is a very important consideration for the safety of the
occupants in the building and for the most economical use of the
water heater.
Property Damage Hazard
All water heaters eventually leak.
•
Do not install without adequate drainage.
•
CAUTION
Whether replacing an existing water heater or installing the water
heater in a new location observe the following critical points:
1. The water heater must be located indoors.
2. The water heater must not be located in an area where it will
be subject to freezing temperatures.
3. Locate the water heater so it is protected and not subject to
physical damage by a moving vehicle.
4. Locate the water heater on a level surface.
5. Locate the water heater near a floor drain. 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 metal drain pan, adequately
drained, be installed under the water heater.
6. Locate the water heater close to the point of major hot water usage.
7. Locate the water heater close to a 120 VAC power supply.
See Power Supply on page 14 for requirements.
