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. If such a location is not available install an auxiliary catch pan.
This appliance is rated Category IV (pressurized vent, likely to form
condensate in the vent) and requires a special vent system designed
for pressurized venting.
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
annually by a qualified service technician.
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.
A. Operation and Installation Warnings
To avoid serious injury or death, read, understand, and follow all of
the precautions listed here.
DANGER
!
Vapors from flammable liquids will explode and cause a fire,
resulting in personal injury or death. The water heater has a burner
that can come on at any time and ignite vapors. DO NOT use or
store flammable liquids around the water heater.
Improper venting can cause a build-up of carbon monoxide.
Breathing carbon monoxide can result in brain damage or death.
DO NOT operate the water heater unless it is properly vented to
the outside and has an adequate fresh air supply for safe operation.
Inspect the exterior exhaust gas outlet port and fresh air inlet port
on a regular basis to ensure they are functioning properly.
A concentration of carbon monoxide as small as .04% (400 parts
per million) in the air can be fatal. When making high fire or low
fire adjustments, CO levels must be monitored using a calibrated
combustion analyzer such that a CO level of no more than 150
ppm is exceeded at any time during operation.
Adjusting the “low fire offset” or the “main flow restrictor” in small
increments can result in a significant increase in CO concentration.
To avoid serious injury or death, DO NOT make any adjustments
to the gas valve without monitoring the exhaust gases with a fully
functional and calibrated combustion analyzer.
Failure to follow these instructions will result in property damage,
severe personal injury, or death.
NOTE:
If the water heater is exposed to fire or water (or is any way
damaged), do not operate. Immediately call a qualified service
technician. Failure to follow this information could result in property
damage, severe personal injury, or death.
WARNING
!
The manufacturer cannot anticipate every circumstance that might
involve a potential hazard. Each installation has its own specialized
characteristics, requirements, and possible hazards. Therefore, all
possible incidents are not included in these warnings. Proper and
safe installation, operation, and service are the responsibility of the
qualified service technician.
Proper care of the water heater is the user’s responsibility. Ensure the
user carefully reads and understands the User’s Information Manual
before operating the water heater.
Make sure the user knows the location of the gas shut-off valve and
how to operate it. Immediately close the gas shut-off valve if the
appliance is subjected to fire, overheating, flood, physical damage, or
any other damaging condition that might affect the operation of the
unit. Have the appliance checked by a qualified service technician
before resuming operation.
Do not power up the unit unless the gas and water supply valves are
fully opened. Make sure the fresh air intake port and exhaust gas port
are open and functional.
No one but a qualified service technician should attempt to install,
service, or repair this water heater. There are no serviceable parts
which can be changed by the user / owner.
User / Owner: Contact the original qualified service technician if the
water heater needs repair / maintenance. If the original technician
is unavailable, ask your gas supplier for a list of qualified service
providers.
DO NOT store or place newspapers, laundry, or other combustible
items near the appliance or the exterior exhaust gas outlet and/or
fresh air inlet port.
The owner should inspect the system monthly for damage, water
stains, signs of rust, corrosion, and exhaust vent and air intake
blockage. If inspection of the unit shows signs of damage, the water
heater should be shut off until the problem is repaired by a qualified
technician.
After installation, all appliance safety devices should be tested.
Carefully consider installation location and the placement of critical
components (circulators, condensate neutralizers, etc.) before
installing the water heater.
DO NOT allow children to operate this water heater. DO NOT use
this water heater if it does not appear to be operating correctly. A
qualified service technician should service and inspect the water
heater annually.
This water heater must be installed by a licensed plumber, licensed
gas fitter, and/or professional service technician. Improper installation
and/or operation can cause a potentially hazardous situation, which,
if not avoided, could result in serious injury or death, and will void
the warranty.
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.
