Outdoor Crest Supplemental Manual

Determine boiler location
The Outdoor Crest gas manifold and controls
met safe lighting and other performance
criteria when the boiler underwent tests
specified in ANSI Z21.13 – latest edition.
Do not install the unit under a deck.
Do not install the unit in a well, stairwell,
alcove, courtyard or other recessed area.
Do not install outdoor units on stack
frames. Failure to comply with the above
may result in severe personal injury, death
or substantial property damage.
Installation must comply with:
• Local, state, provincial, and national codes, laws, regulations,
and ordinances.
• National Fuel Gas Code, ANSI Z223.1 – latest edition.
• Standard for Controls and Safety Devices for Automatically
Fired Boilers, ANSI/ASME CSD-1, when required.
• National Electrical Code.
Before locating the boiler, check:
1. Check for nearby connection to:
• System water piping
• Gas supply piping
• Electrical power
2. - Keep venting areas free of obstructions.
- Keep area clean and free of combustible and flammable
materials.
- To avoid a blocked air inlet or blocked flue condition,
keep the outdoor air inlet and flue outlet clear of leaves,
debris, etc.
4. If a new boiler will replace an existing boiler, check for
and correct system problems, such as:
•
System leaks causing oxygen corrosion or heat
exchanger cracks from hard water deposits.
• Incorrectly-sized expansion tank.
• Debris left from existing piping, if not flushed and
cleaned with an appropriate cleaner.
⚠
WARNING
NOTICE
3. Check area around the boiler. Remove any combustible
materials, gasoline and other flammable liquids.
Outdoor models must be installed outdoors
only and must use the outdoor air inlet hood
assembly along with the vent termination
cap supplied by the manufacturer. Personal
injury or product damage may result if any
other venting is used or if an outdoor model
is used indoors. All covers, doors and jacket
panels must be properly installed to ensure
proper operation and prevent a hazardous
condition.
⚠
WARNING
⚠
WARNING
The unit must not be installed in an area
that is enclosed by walls or a fence that
will block free wind movement around
the appliance. Free movement of wind
around the outdoor unit is required
to carry away the flue products and
provide combustion air. The flue outlet/
combustion air inlet of an outdoor unit
must not be installed closer than 10 feet
from an inside corner of an L-shaped
structure. Walls or enclosed fencing may
cause eddy currents which can recirculate
the flue products into the combustion
air inlet. Recirculation of flue products
may cause operational problems, bad
combustion or non-warrantable damage
to controls.
Locate the unit at least 3 feet (0.91m)
outside any overhang.
⚠
CAUTION
CAUTION
Do not install in locations where rain from
building runoff drains will spill onto the
unit.
Do not locate the unit so that water
from sprinklers may spray directly onto
it. Water may damage controls or other
electrical components.
Failure to keep boiler area clear and free
of combustible materials, gasoline, and
other flammable liquids and vapors can
result in severe personal injury, death, or
substantial property damage.
⚠
WARNING
This product contains a condensate
management and disposal system that
may be subject to freezing if exposed
to sustained temperatures below 32°F.
Precautions should be taken to protect
the condensate trap and drain lines during
extended periods of outdoor temperatures
below 32°F.
The Outdoor Crest is NOT suitable for
installation in areas which may experience
temperatures below 32°F.
⚠
WARNING
Do not locate unit so that high winds can
deflect off of adjacent walls, buildings
or shrubbery causing recirculation.
Recirculation of flue products may cause
operational problems, bad combustion or
damage to controls. Locate unit at least
3 feet (0.91m) from any wall or vertical
surface to prevent wind conditions from
affecting performance.
⚠
CAUTION
Do not install outdoor models directly on
the ground. You must install the outdoor
unit on a level concrete, brick, block, or
pressure-treated wood platform.
