To adjust high fire:
Required Tools: Flat head screwdriver and Combustion
analyzer
Start the boiler and observe proper operating parameters for
the system. Set boiler to the "
BNR ON TEST HI
above, to achieve maximum firing rate of the boiler. Check
combustion readings using the combustion analyzer. If
combustion readings are not in accordance with Table 3.11.2,
adjust as follows: Open the front panel of the boiler. Locate
the automatic gas valve. Turn the orifice adjusting screw,
located on the downstream side of the valve, in the direction
indicated on the sticker to increase or decrease the gas flow.
Increasing the gas flow decreases the combustion exhaust
, while decreasing the gas flow increases the combustion

exhaust . There will be a slight time delay between the

adjustment and the response of the CO /O

instrument. Adjust the settings in small increments and allow
the combustion readings to stabilize before readjusting.
When desired adjustments are complete, check and adjust
low fire if necessary.
To adjust low fire:
Required Tools: 2.5 mm hex wrench and Combustion
analyzer
Start the boiler and observe proper operating parameters
for the system. Set boiler to the " BNR ON TEST LOW
described above, to achieve minimum firing rate of the
boiler. Check combustion readings using the combustion
analyzer. If combustion readings are not in accordance with
Table 3.11.2, adjust as follows: Open the front panel of the
boiler. Locate the automatic gas valve. Turn the offset screw,
located in the bottom center of the side of the valve, in the
direction indicated on the label to increase or decrease the
gas. Increasing the gas decreases the , while decreasing

between the adjustment and the response of the
measuring instrument. Adjust the settings in small increments
and allow the combustion readings to stabilize before
readjusting. When desired adjustments are complete, check
and adjust hi fire if necessary.
3.11.3 Checking Flame signal
Using the control panel, enter the information mode and scroll down view the flame signal. This shows μA when
the boiler is firing and shows 0μA when the boiler is not firing. 7-8μA is a strong flame signal.

Become familiar with the
basic operation of the boiler.
The interior of the front door

Instructions.

4.1.2 Factory tests

Safe lighting and other
performance criteria were met
with the gas manifold and
control assembly provided
on this boiler when the boiler
underwent factory tests
specified in
ANSI Z21.13/CSA
, latest edition. (See "Factory
4.9
Firetest" label.)

4.2.1 lighting Procedures

1. Make sure the system is filled with water and water is circulating in the system.
Turn on electrical supply and open the gas supply valves to the boiler.
2. Turn the on/off switch to the on position. If an error is indicated, see Section
5.5 of this manual to troubleshoot the problem and take the necessary corrective
action before proceeding.
3. Set the desired high temperature limit and operating temperature. The
controller will now complete the automatic firing sequence.

4.2.2 Normal shut Down Procedures

1. Close all manual gas valves.
2. Turn off electric power.
4.3 e
MergenCy
In case of emergency, shut off gas at a valve external to the boiler. See
diagram at right for valve locations.

WARNING
Do not use this boiler if any part
has been under water. Immediately
call a qualified service technician
to inspect the boiler and to replace
any part of the control system and
any gas control which has been
under water.
!
WARNING
If overheating occurs or the gas
supply fails to shut off, do not turn
off or disconnect the electrical
supply to the pump. Instead, shut
off the gas supply at a location
external to the boiler.
