Locating The Water Heater - Westinghouse WGRGH20**75F Series Installation, Start-Up, Maintenance, Parts, Warranty

Carefully consider installation when determining heater location.
Please read the entire manual before attempting installation.
Failure to properly take factors such as heater venting, piping,
condensate removal, and wiring into account before installation
could result in wasted time, money, and possible property damage
and personal injury.
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: upright, with the exhaust vent adapter
in the vertical position. 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 o
lower than 114 F / 46
• 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.
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.
2. Check for nearby connections to:
• System water piping
• Venting connections
• Gas supply piping

F. Precautions
• Electrical power
• Condensate drain
All water heaters eventually leak. Locate the water heater 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 water heater 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 water heater installation. Such a drain pan must
have a clearance of at least 1.0" (2.5 cm) greater than any point on
the water heater's outer jacket and must be piped to an adequate
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
WATER HEATER INSTALLATION WHERE A LEAKAGE OF WATER COULD
RESULT IN PROPERTY DAMAGES.
3. Check area around heater. Remove any combustible materials,
gasoline, and other flammable liquids.
o
C and
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.
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
o
F
• Incorrectly sized expansion tank
6. Clean and flush system when reinstalling a heater.
Do not connect the water heater to any heating systems or
components that have been previously used for non-potable
applications.
Do not introduce toxic chemicals, such as antifreeze or water heater
treatments, into the water heater or any piping meant for potable
water purposes.
Ensure that all piping and components connected to the water
heater are suitable for potable water applications.
Do not use this water heater for space heating applications.
Circulators suitable for DHW applications must be used.
7. When the appliance is installed directly on carpeting, the appliance
shall be installed on a metal or wood panel extending beyond the
full width and depth of the appliance by at least 3" (76.2 mm) in any
direction or, if the appliance is installed in an alcove or closet, the entire
floor shall be covered by the panel. The panel must be strong enough
to carry the weight of the heater when full of water.
