Part 1 - General Safety Information

This water heater is approved for indoor installations only and is
not intended for use as a pool heater. Clearance to combustible
materials: 0" top, bottom, sides, and back. Heater must have room
for service: 24" front, 3" left and right sides, 6" top, and 0" back
are minimum recommended service clearances. (A combustible
door or removable panel is acceptable front clearance.) This water
heater has been approved for closet installation and installation on
combustible flooring. Do not install directly on carpeting. Install the
water heater in a location where temperature and pressure relief
valve discharge or a leak will not result in damage to the surrounding
area. Use only Category IV vent systems.
Installer - Read all instructions in this manual before installing.
Perform steps in the given order.
User - This manual is for use only by a qualified heating installer
/ service technician. Have this water heater serviced / inspected

FAILURE TO ADHERE TO THE GUIDELINES ON THIS PAGE
CAN RESULT IN SUBSTANTIAL PROPERTY DAMAGE, SEVERE
PERSONAL INJURY, OR DEATH.
NOTE: Obey all local codes. Obtain all applicable permits before
installing the water heater.
NOTE: Install all system components and piping in such a manner
that does not reduce the performance of any fire rated assembly.
NOTE: If the water heater is exposed to the following, do not
operate. Immediately call a qualified service technician.
1. Fire
2. Damage
3. Water
Failure to follow this information could result in property damage,
severe personal injury, or death.
DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN
SUBMERGED IN WATER. Immediately call a qualified service
technician. The water heater MUST BE replaced if it has been
submerged. Attempting to operate a water heater that has been
submerged could create numerous harmful conditions, such as
a potential gas leakage causing a fire and/or explosion, or the
release of mold, bacteria, or other harmful particulates into the
air. Operating a previously submerged water heater could result in
property damage, severe personal injury, or death.
NOTE: Water heater damage due to flood or submersion is
considered an Act of God, and IS NOT covered under product
warranty.
Altering any Westinghouse water heater with parts not
manufactured by Westinghouse WILL INSTANTLY VOID the water
heater warranty and could result in property damage, personal
injury, or death.
This water heater has been designed to heat potable water ONLY.
Using this water heater to heat non-potable fluid WILL VOID
product warranty, and could result in property damage, personal
injury, or death.
Do not use this water heater for anything other than its intended
purpose (as described in this manual). Doing so could result in
property damage and WILL VOID product warranty.
High heat sources (sources generating heat 100
such as stove 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.
A. Improper Combustion
Do not obstruct the flow of combustion and ventilating air. Adequate
air is necessary for safe operation. Failure to keep the exhaust vent
and combustion air intake clear of ice, snow, or other debris could
result in property damage, serious personal injury, or death.
B. Gas
Should overheating or gas supply fail to shut off, turn off the manual
gas control valve to the water heater.
C. When Servicing the Water Heating System
Be sure to disconnect electrical power before performing service.
Failure to do so could result in electrical shock, property damage,
serious personal injury, or death.
To avoid electric shock, disconnect electrical supply before performing
maintenance.
NOTE: When inquiring about service or troubleshooting, reference the
model and serial numbers from the water heater rating label.
To avoid severe burns, allow water heater and associated equipment
to cool before servicing.
D. Heater Water
Do not use petroleum-based cleaning or sealing compounds in a water
heating system. Gaskets and seals in the system may be damaged. This
can result in substantial property damage.
Do not use "homemade cures" or "patent medicines". Damage to the
water heater, substantial property damage, and/or serious personal
injury may result.
E. Freeze Protection
NOTE: Consider piping and installation when determining heater
location.
Failure of the water heater due to freeze related damage IS NOT
covered by product warranty.
NEVER use any toxic chemical, including automotive, standard glycol
antifreeze, or ethylene glycol made for hydronic (non-potable)
systems. These chemicals can attack gaskets and seals in water
systems, are poisonous if consumed, and can cause personal injury
or death.
UNCRATING THE WATER HEATER - Any claims for damage or
shortage in shipment must be filed immediately against the
transportation company by the consignee.
