B. System Check
1. Verify that the venting, water piping, gas piping
and electrical system are installed properly.
Refer to installation instructions contained in
this manual.
2. Confirm all electrical, water and gas supplies
are turned off at the source and the chimney/
vent is clear of obstructions. If boiler is
controlled by an external control system, this
system must be temporarily disconnected.
The local boiler controls should be allowed to
operate the boiler.
3. Confirm that all manual shut-off valves between
the boiler and gas supply are closed.
C. Power the Boiler
Turn on the electrical supply to the boiler and
circulation system at fused disconnect switch. Ensure
that the circuit breaker switch is in the “ON” position.
D. Power the Circulators
Turn system circulators on and purge air from the
boiler and system piping.
E. Pressurize the Fuel System
1. Open the manual gas shut-off valves located
upstream of the field supplied gas regulator.
Do not open manual gas valve directly outside
the boiler jacket.
2. Purge gas line of air.
3. Open manual ball valve outside boiler jacket.
Confirm that the supply pressure to the manual
ball valve tapping outside the boiler jacket
conforms to Table 18 for maximum and
minimum supply pressure.
4. Repeat Step 2 and Step 3 for boiler gas train
components.
F. Boiler Commissioning
All of the installation instructions found in Sections I
through VI shall be completed before commissioning
the boiler.
DANGER
Failure to properly adjust excess air will result in
unsafe levels of carbon monoxide. Variations in
venting or combustion air pressure and temperature
will change excess air. Adjust excess air levels so that
variation in venting or combustion air pressures and
temperatures caused by change of seasons, wind
conditions, opening or closing of boiler room doors
or windows do not cause the boiler to operate with
carbon monoxide concentration above 400 parts
per million.
1. Identify boiler water, gas and/or LP, electrical
connections, and other safety controls.
2. Locate manometer pressure taps for pressure
measurements in the following areas:
a. Supply gas pressure (
ball valve tapping
outside of boiler top jacket panel
)
b. Stack or flue outlet pressure
3. Install a gas analyzer probe within 6” above the
boiler flue gas outlet.
4. Verify the high temperature limit (auto reset)
is set to 200° F. (
1000 only
)
5. Verify the high and low gas pressure switch
limits.
a. High gas pressure switch at 1.0” w.c.
b. Low gas pressure switch at 3.0” w.c.
6. For Commissioning Free Flex 1000 - Free Flex
3000 go to Section G or for Commissioning
Hight Turndown or Dual Fuel Free Flex 1500 -
Free Flex 6000 go to Section I.
G. Commissioning Free Flex 1000 - Free Flex 3000
1. Menu > Operation > Auto / Manual Rate
Control > Manual (
76 password required
)
2. Switch boiler circuit breaker in the control panel
to the ON Position (Free Flex
1000 only
).
3. Close the manual gas valve between the
automatic gas valve and the blower inlet.
4. Cycle the boiler. The boiler should lockout on
gas pressure failure. In this case it should be
the low gas pressure switch.
