•
This burner must be installed and prepared for start-
up by a qualified service technician who is trained
and experienced in commercial gas burner system
installation and operation.
•
Do not attempt to start the burner unless you are fully
qualified.
•
Do not continue with this procedure until all items in
the 'Prepare the Burner for Start-up' section have
been verified.
•
Carefully follow the wiring diagrams, control instruc-
tion sheets, flame safeguard sequence of operation,
test procedures and all appliance manufacturer's
di-
rections that pertain to this installation.
•
If any of these items are not clear or are unavailable,

Burner
start
procedure:
(Before
proceeding,
turn off and lock out
electrical
power
and close
the main leak test
cock
to shut
off gas to the burner.)
1. With the power and main gas supply to the burn-
er turned off, make sure gas has not accumu-
lated in the boiler or flues.
.
.
Check the initial air settings (shutter & band) for
input firing rate. Check the manufacturer's
set-
tings either on the nameplate shown in Figure
1 or listed in Table 2. If adjustment is necessary
refer to Figure 11 and loosen the adjustment
screws then twist the shutter and/or air band un-
til the indicators point to the values shown on the
nameplate or listed in Table 2.
With the main gas supply valve closed. Set the
limit or controller to call for heat then apply pow-
er to start the burner. Reset the high and low gas
pressure switches if necessary.
.
.
In order to check the function of each component
(i.e: flame safeguard sequence, airflow proving
switch, ignition transformer,
gas valves, safety
lockout timing, etc.), with the gas supply closed
off, monitor a complete
burner run sequence.
Note that the flame safeguard control will lock
out since the fuel supply has been closed off.
If component operation sequence and function
is correct, reset the flame safeguard and initi-
ate a new cycle. Monitor the start-up cycle and
manually open the main leak test cock as soon
as the flame safeguard powers the safety shut-
off valves.
If the boiler room is quiet you may
be able to hear the valve open, if not you can
generally place your hand on the valve and feel
it open.
After you have observed main flame
for a brief time, trip any of the switches in the
limit string to shut the burner down. Monitor the
flame and safety shutoff valves to assure that
shutdown
is controlled
by the valves and that
they operate properly. With this test passed you
may safely initiate automatic start-ups on subse-
quent cycles.
Verify
input
firing
rate:
.
Clock the meter for CFH and calculate the input
firing rate. Compare the calculated
rate to the
specified input for the boiler found on the speci-
fication sheets and on the rating plates for the
burner and boiler. Do not exceed the specified
maximum input for the boiler.
.
Attach a manometer
to the manifold test port,
clock the meter, and adjust the regulated pres-
sure until the specified input level is achieved.
Refer to Table 2.
3. Be sure to set the breech or furnace pressure to
the correct value, since this will have an effect on
the manifold pressure.
