XIII. System Start-up
A. Check System Setup
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 that venting is clear
of obstructions.
3. Flush the system to remove sediment, flux, and
other contaminants. This must be done with the
appliance isolated from the system.
4. Fill the hot water system with treated water as
specified in the water quality section of this manual.
a. Maintain at least 15 psi primary loop pressure.
5. Power the appliance. Turn on the electrical supply to
the appliance and circulator at the fuse disconnect
switch.
6. Power the circulator(s). Turn system circulator(s) on
and purge air from the system.
7. Pressurize the fuel line.
a. Open the manual gas shut-off valves located
upstream of the field supplied gas regulator.
b. Check gas piping for leaks and purge gas line of air.
c. Ensure the incoming gas pressure is within the
min and max on the rating label. Also, ensure the
setting for the high and low gas pressure switches
are within the limits given in
d. Reset high and low gas pressure switches by
pressing the reset button.
B.
Start the AMP
Start the appliance using "Operating Instructions"in
Figure 27.
1. Allow the appliance to complete its standard startup
sequence: pre-purge, pre-ignition, and drive light-
off.
2. Refer to the Concert Control manual to select the
desired control mode.
3. It may take a couple of ignition attempts before a
flame is established. After the first ignition failure,
the appliance goes into a hard lockout and a
manual reset using the Concert Control is required
to restart. If ignition is not achieved in three
consecutive attempts, contact factory or a qualified
heating service technician.

only by trained and skilled personnel from a qual
-
ified service agency. Follow these instructions ex
-
actly. Improper installation, adjustment, service or
maintenance can cause property damage, personal
injury, or loss of life.
The maximum operating pressure of this appliance
is 150psi (1034 kPa) with the factory installed tem
-
perature and pressure relief valve. Never exceed
the maximum allowable working pressure on the
heat exchanger ASME plate.
The outlet pressure for the gas valve has been
factory set and requires no field adjustment. At
-
tempting to adjust the outlet pressure may result
in damage to the gas valve and cause property
damage, personal injury or loss of life.
Each AMP Series appliance is tested at the factory
and adjustments to the air fuel mixture are nor
-
mally not necessary. Improper gas valve or mixture
adjustments could result in property damage,
personal injury, or loss of life.
Any gas valve adjustments (throttle and/or offset)
specified herein and subsequent combustion data
(%O
2
, %CO
2
, CO air free ppm) collection must be
performed using a calibrated combustion analyzer.
