SECTION 4.
INITIAL START-UP
4.1 INITIAL START-UP REQUIREMENTS
The following are the prerequisites for the initial start-up of the Benchmark boiler:
•
Complete the installation per the
Benchmark 750-6000 with Edge [i]: Install-Startup
Manual
(OMM-0144, GF-217), including gas supply piping, vent installation and
condensate drain piping. Starting a unit without the proper piping, venting, or electrical
systems can be dangerous and may void the product warranty.
•
Set proper controls and limits (see Section 4:
Advanced Setup
in the
Edge [i] Controller
Manual
, OMM-0141, GF-213-B).
Initial start-up consists of the following:
•
Combustion calibration (Section 4.4:
Combustion Calibration
)
•
Test safety devices (Section 5:
Safety Device Testing
)
Start-up must be successfully completed before putting the unit into service. The start-up
instructions below should be followed precisely in order to operate the unit safely and at high
thermal efficiency and low flue gas emissions.
Initial unit start-up
must be
performed by AERCO factory trained personnel, who are trained in
the start-up and service of Benchmark boilers.
An AERCO Gas Fired Startup Sheet, included with each Benchmark unit, must be completed
for each unit for warranty validation and a copy must be returned promptly to AERCO via e-mail
at:
.
WARNING!
DO NOT ATTEMPT TO DRY FIRE THE UNIT.
Starting the unit without a full water level can
seriously damage the unit and may result in injury to personnel and/or property damage. This
situation will void any warranty.
NOTE:
AERCO recommends that the
Standby Blower Voltage
parameter be kept at 2.00 volts (the
default set at the factory) to prevent flue gas recirculation.
To check, g
o to the Controller’s
Main Menu
→
Advanced Setup
→
Performance
→
Fire
Control
→
Operating Control
and verify that the
Standby Blower Voltage
parameter is set
to
2.00 V
.
However, individually vented units in positive pressure boiler rooms may set
Standby Blower
Voltage
between
2.00
and
0
volts to compensate.
