3.1 Compliance with Standards and Regulations

The installation must conform to the requirements of the authority
having jurisdiction or, in the absence of such requirements, to the
latest edition of the National Fuel Gas Code, ANSI Z223.1./NFPA 54. In
Canada, installation must be in accordance with the requirements
of CAN/CSA B149.1, Natural Gas and Propane Installation Code.
This condensing gas boiler complies in its design and mode of
operation with the American National Standard ANSI Z21.13/CSA4.9,
latest edition for Gas Fired Low Pressure Steam and Hot Water
Boilers.
Other confirmed approvals and certifications are indicated by
labels on the boiler.
Where required by the authority having jurisdiction, the installation
must conform to the Standard for Controls and Safety Devices for
Automatically Fired Boilers, ANSI/ASME CSD-1.
Install CO detectors per local regulations. Boiler requires yearly
maintenance (see "Appendix D - Maintenance").

3.2 Operating Limits of the Boiler

The heat exchanger has been designed and certified in accordance
with the ASME Boiler and Pressure Vessel Code, Section IV.
The hot water distribution system must comply with all applicable
codes and regulations. When replacing an existing boiler, it
is important to check the condition of the entire hot water
distribution system to ensure safe operation. Common practice
calls for inspecting an existing system in its entirety and bringing it
up to code. All pipework should be properly cleaned and flushed.

4 INSTALLATION

4.1 Introduction

This Chapter provides the descriptions and procedures necessary
to unpack, inspect and install the
AR 1500 and AR 2000.

4.2 Receiving the Unit

Each Array Boiler System is shipped as a single crated unit. The
unit must be moved with the proper lifting equipment for safety
and to avoid equipment damage. The unit should be completely
inspected for evidence of shipping damage and shipment
completeness at the time of receipt from the carrier and before
the bill of lading is signed.
NOTE: R is not responsible for lost or damaged freight. Any
visual damage to the packaging materials must be reported to the
delivering carrier.

4.3 Unpacking

Carefully unpack the unit, pay particular attention not to damage
the unit enclosure when cutting away packaging materials.
After unpacking, a close inspection of the unit should be made
to ensure that there is no evidence of damage. The freight carrier
should be notified immediately if any damage is detected.
The following accessories come standard with each unit and are
either packed separately within the unit's shipping container or
are factory installed on the unit:
− Pressure/Temperature Gauge
− ASME Pressure Relief Valves
− Condensate Drain Traps
− Outdoor Sensor
− System Supply Sensor (lead length: 20 ft) and Sensor well.
When optional accessories are ordered, they may be packed
within the unit's shipping container, factory installed on the unit,
or packed and shipped in a separate container. Any standard
or optional accessories shipped loose should be identified and
stored in a safe place until ready for installation or use.

4.4 Site Preparation

Ensure that the site selected for installation of the Array AR 1000,
AR 1500 and AR 2000 Boiler includes:
− Access to AC Input Powerat 120VAC, single phase, 60Hz for
AR 1000-1500 and 230VAC, single phase, 60Hz for AR 2000
− Access to Natural Gas line at a recommended minimum
pressure of 8 inches w.c. for 1,000,000 BTU/hr energy input
for the AR 1000, 1,500,000 BTU/hr energy input for the AR 1500
OR 2,000,000 BTU/hr energy input for the AR 2000.
− The boilers should be mounted on a concrete service/
housekeeping pad 3,5-4" in height.
− The boiler should be located close to a floor drain in an
area where leakage from the appliance or connections will
not cause damage to the adjacent area or lower floor levels
in the building.
