COLD WEATHER HANDLING
- If the appliance has been stored in
a very cold location (BELOW 0
o
F) before installation, handle with
care until the components come to room temperature. Failure to
do so could result in damage to the appliance.
Carefully consider installation when determining appliance
location. Please read the entire manual before attempting
installation. Failure to properly take factors such as appliance
venting, piping, condensate removal, and wiring into account
before installation could result in wasted time, money, and
possible property damage and personal injury.
This appliance is certified for indoor use only. DO NOT INSTALL
OUTDOORS. Outdoor installations ARE NOT covered by warranty.
Failure to install the appliance indoors could result in property
damage, severe personal injury, or death.
A. Locating the Appliance
1. Installation Area (Mechanical Room) Operating Conditions
• Ensure ambient temperatures are higher than 32
o
F / 0
o
C
and lower than 104
o
F / 40
o
C
• 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
This appliance must be installed upright in the vertical position as
described in this manual. DO NOT attempt to install this appliance
in any other orientation. Doing so will result in improper appliance
operation and property damage, and could result in serious
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 an appliance or components due to incorrect
operating conditions IS NOT covered by product warranty.
• NOTE: To prevent condensing in the fan, it is recommended to
avoid prolonged exposure to temperatures below 45
o
F
This appliance has a condensate disposal system that may freeze
if exposed to sustained temperatures below 32
o
F. Precautions
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 appliance. Remove any combustible materials,
gasoline, and other flammable liquids.
Failure to keep the appliance area clear and free of combustible
materials, liquids, and vapors can result in substantial property
damage, severe personal injury, or death.
The service life of the appliance’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 appliance components. In these environments,
appliances must not be installed using direct vent systems which
draw outdoor air for combustion. Such appliances 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.
