A 1”, 1-1/2” or 2” Natural Gas Supply Shutoff Valve, and a Propane Shutoff Valve
on Propane and Dual Fuel units
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.
2.4 SITE PREPARATION
Ensure that the site selected for installation of the Benchmark Platinum Boiler includes:
•
Access to a natural gas and/or propane gas supply that conforms to the pressures
specified in the
Benchmark Gas Supply Design Guide
(TAG-0047, GF-2030).
•
Access to AC input power specified in the
Benchmark Electrical Power Design Guide
(TAG-0048, GF-2060).
•
To ensure proper condensate drainage, the unit must be installed on a level concrete
“housekeeping” pad. See Section 2.4.3 for pad requirements.
2.4.1 Installation Clearances
All Benchmark models are the same height, but vary in depth by model. The unit must be
installed with the prescribed clearances for service as shown in Figure 2-1a through 2-1e. The
minimum clearance dimensions, required by AERCO, are listed below for all models. However,
if Local Building Codes require additional clearances, these codes shall supersede AERCO’s
requirements.
The
minimum acceptable clearances
required are as follows:
BMK750
– 5000N
•
Front: 24 inches (61 cm)
•
Sides: 24 inches (61 cm)
•
Rear: 24 inches (61 cm)
•
Top: 18 inches (45.7 cm)
BMK5000-6000
•
Front: 36 inches (91 cm)
•
Sides: 24 inches (61 cm)
•
Rear: 24 inches (61 cm)
•
Top:
18 inches (45.7 cm)
All gas piping, water piping and electrical conduit or cable must be arranged so that they do not
interfere with the removal of any panels or inhibit service or maintenance of the unit.
In multiple unit installations, it is important to plan the position of each unit in advance. Sufficient
space for piping connections and future service/maintenance requirements must also be taken
into consideration. All piping must include ample provisions for expansion
.
NOTE:
Benchmark units may be installed with zero side clearances in pairs only. The perimeter
clearances still apply. See drawings in
Appendix A:
Dimensions and Clearance Drawings
.
If installing a Combination Control System (CCS) using an ACS panel (ACS is not needed for
combination mode, but can still be used if installing with a legacy BMK unit, or if you already
have a panel want to continue to use it), it is important to identify the
Combination Mode
Boilers in advance and place them in the proper physical location. For more information refer to
Section 6.6:
Combination Control System
of the
Benchmark Platinum-Edge: Operation-Service-
Maintenance Manual
(OMM-0137, GF-211).
