•
Condensate Removal Pump (Part # 554200)
NOTE:
When using an optional system sensor, pipe insulation must be
wrapped around it to improve temperature measurement accuracy
and increase overall system efficiency.
Part 3 - Prepare the Water Heater Installation
Remove all sides of the shipping crate to allow the heater to be moved
into its installation location.
COLD WEATHER HANDLING
- If the water heater 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 water heater.
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.Choosing an Outdoor Installation Location
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.
The outdoor unit is intended for use in outdoor installations ONLY.
DO NOT install the water heater indoors. Installing the water heater
indoors will result in improper water heater operation, property
damage, serious personal injury, or death.
1. Outdoor Installation Area Operating Conditions
• Heater must be placed in an area where the exhaust plume
will not be recirculated into the louver system located on the
front access panel. Avoid fences or walls that extend above
the exhaust vent termination. Pipe the exhaust vent so that
it terminates level with or above the fence, wall, or enclosed
area.
• Do not install heaters in locations where rain from building
runoff may spill onto the heater. Doing so could result in
premature product failure. Such failures ARE NOT covered
by warranty.
• Do not locate where sprinklers may spray directly onto the
heater cabinet and possibly into the louvers, which could
damage the control system and internal components of the
water heater. Such damages ARE NOT covered by warranty.
• Do not install directly on the ground, as the water heater
is heavy when filled with water. Install the heater level on
a concrete pad, block, or pressure treated wood platform,
designed to support the weight of the water heater and
components when filled with water. The water heater must
be properly supported and installed level in order to operate
and drain condensate properly.
• Do not install the water heater under a deck or porch.
• Do not install the water heater in a well, stairwell, alcove,
courtyard, or other recessed area.
• Do not install the water heater on stack frames.
• In areas where heater is exposed to sustained temperatures
below 32
o
F, provisions must be made to protect the water
heater, condensate lines, and piping from freezing. The
use of heat tape is recommended to avoid freezing. It is
also recommended to bush up the condensate line size to
1” and terminate condensate discharge line as close to the
unit as possible. Longer condensate runs are more prone to
freezing.
• Locate heater at least 10’ away from any forced air inlet.
Maintain a clearance of at least 48” below or horizontal from
any window, door, walkway, or gravity air intake. Never place
heater under a porch.
• In areas where it can get extremely hot (over 100
o
F, it is
recommended to install the heater in an area that avoids
direct sunlight to keep the internal components cooler.
Failure to follow this instruction could lead to premature
failure. Such failures ARE NOT covered by warranty.
These heaters are design certified for outdoor installations. Heaters
must not be installed under an overhang unless clearances are in
accordance with local codes, the requirements of the gas supplier /
utility, and the AHJ. Three sides must remain open in the area under
the overhang. Roof water drainage must be diverted away from
heaters installed under overhangs. Failure of heater or components
due to incorrect operating conditions IS NOT covered by product
warranty.
When installing the heater outdoors, ensure the installation
location is not near the exhaust or intake terminations of other
gas-fired products – boilers, water heaters, furnaces, etc. Failure to
do so could result in the recirculation of exhaust fumes. Exhaust
recirculation could result in a hazardous condition and cause
substantial property damage, severe personal injury, or death.
