Locating The Water Heater; Leveling - Westinghouse WGR050NG076 Installation, Start-Up, Maintenance, Parts, Warranty

A. Locating the Water Heater
This water heater is certified for indoor use only. DO NOT INSTALL
OUTDOORS. Outdoor installations ARE NOT covered by warranty.
Failure to install the water heater indoors could result in property
damage, severe personal injury, or death.
Incorrect ambient conditions can lead to damage to the heating
system and put safe operation at risk. Ensure that the installation
location adheres to the information included in this manual.
Failure to do so could result in property damage, serious personal
injury, or death. Failure of heater or components due to incorrect
operating conditions IS NOT covered by product warranty.
This water heater must be installed upright in the vertical position
as described in this manual. DO NOT attempt to install this water
heater in any other orientation. Doing so will result in improper
water heater operation and property damage, and could result in
serious personal injury or death.
1. Installation Area (Mechanical Room) Operating Conditions
• Ensure ambient temperatures are higher than 32
o
and lower than 104 F / 40
• Prevent the air from becoming contaminated by the
products, places, and conditions listed in this manual
• Avoid continuously high levels of humidity
• Never close existing ventilation openings
• Ensure a minimum 1" clearance around hot water and
exhaust vent pipes
• NOTE: To prevent condensing in the fan, it is recommended
to avoid prolonged exposure to temperatures below 45
This water heater has a condensate disposal system that may freeze
if exposed to sustained temperatures below 32
should be taken to protect the condensate trap and drain lines
from sustained freezing conditions. Failure to take precautions
could result in property damage, severe personal injury, or death.
2. Check for nearby connections to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power
• Condensate drain
3. Check area around heater. Remove any combustible materials,
gasoline, and other flammable liquids.
Failure to keep the water heater area clear and free of combustible
materials, liquids, and vapors can result in substantial property
damage, severe personal injury, or death.
High heat sources (generating heat 100
as boiler flue pipes, space heaters, etc.) may damage plastic
components of the water heater as well as plastic vent pipe
materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8" from high heat
sources. Observe heat source manufacturer instructions, as well
as local, state, provincial, and national codes, laws, regulations,
and ordinances when installing this water heater and related
components near high heat sources.

The service life of the water heater's exposed metallic surfaces,
such as the casing, as well as internal surfaces, such as the heat
exchanger, are directly influenced by proximity to damp and salty
marine environments. In such areas higher concentration levels of
chlorides from sea spray coupled with relative humidity can lead to
degradation of water heater components. In these environments,
heaters must not be installed using direct vent systems which draw
outdoor air for combustion. Such heaters must be installed using
room air for combustion. Indoor air will have a much lower relative
humidity, and hence potential corrosion will be minimized.
All appliances eventually leak. Locate the appliance where any
leakage from the relief valve, related piping, tank, or connections
will not result in damage to surrounding areas or lower floors of the
building. Any appliance should be installed in such a manner that if it
should leak the resulting flow of water will not cause damage to the
area in which it is installed. National Plumbing codes require a drain
pan for any appliance installation. This drain pan should be sized with
a maximum depth of 2", and a minimum diameter 2" greater than the
diameter of the appliance. The drain pan should empty into an open

drain line. This drain line should be 3/4" ID minimum, piped to an
open drain. Leakage damages ARE NOT covered by warranty. Failure
to install a drain pan is the sole responsibility of the owner and/or
installer. Reference UPC 2000 (Uniform Plumbing Code) Section 510
- Protection from Damage or IPC 200 (International Plumbing code)
Section 504 - Safety Devices. Leakage damages ARE NOT covered by
warranty.
In addition, water leak detection devices and automatic water shutoff
valves are readily available at plumbing supply houses. IT IS HIGHLY
RECOMMENDED BY THE MANUFACTURER TO INSTALL WATER LEAK

DETECTION DEVICES AND AUTOMATIC SHUTOFF VALVES IN ANY
APPLIANCE INSTALLATION WHERE A LEAKAGE OF WATER COULD
RESULT IN PROPERTY DAMAGES.
Failure of the water heater or components due to incorrect operating
conditions IS NOT covered by product warranty.
4. Gas control system components must be protected from dripping
water during operation and service.
5. If the heater is to replace an existing heater, check for and correct
any existing system problems, such as:
• System leaks
• Location that could cause the system and heater to freeze and
leak
• Incorrectly sized expansion tank
6. Clean and flush system when reinstalling a heater.
NOTE: When installing in a zero clearance location, it may not be
possible to read or view some product labeling. It is recommended to
make note of the heater model and serial number.
NOTE: A combustible door or removable panel is acceptable front
clearance.
B. Leveling
In order for the condensate to properly flow out of the collection
system, the area where you locate the heater must be level. Location
must also fully support the weight of the filled water heater.
