Pressure Switch Settings
The switches have been preset at the factory as
per Table 11. The following description is for the
benefit of the start-up technician should minor
adjustment be required.
Differential air pressure switches are provided to
shut down the gas supply line under block flue
condition. One pressure switch is provided per
burner. If adjustment is necessary the following
steps must be followed: Remove the lower front
jacket panel; insert allen key into the switch
located on the combustion chamber door; with
the fan operating the switch should be set per
Table 11 by rotating the allen key.
Ignition System Safety Shut-Off Device
After initial fill while the main burner is firing,
shut off gas to the pilot and clock the time taken
for the main gas valve to shut down. If the safety
control is functioning properly, power to the gas
valve will be shut off within 4 seconds of the pilot
gas being shut off. If shut down takes longer,
ignition control or gas valve may be defective. If
shutdown does not occur it is possible that the
main flow is generating a signal at the pilot in
which case the pilot shall not recycle with the
pilot gas off.
Appliances Start Up
With the appliance off, open makeup water valve
and allow system to fill slowly. With all air vents
open, run system circulating pump for a
minimum of 30 minutes with the appliance off.
Open all strainers in the circulating system and
check for debris. Check liquid level in expansion
tank. With system full of water at 15 PSIG cold,
the level of water in the expansion tank should
not exceed ¼ of the total volume with the
balance filled with air. Start up appliance
following instructions provided. Operate entire
system including pumps and radiation for at
least 1 hour. Check water level in expansion
tank. If level exceeds ½ of tank volume, air is
still trapped in system. Shut down appliance and
continue to run pumps. Within 3 days of start up,
recheck all air vents and expansion tank as
described above.
9.2 STAGING OPERATION
All MicoFlame® Grande models are available as
on/off, 2-stage, 3-stage and 4-stage. Model
2000 is provided with two burners. Models 2500
and 3000 are provided with three burners and
models 3500 and 4000 are provided with four
burners. Each burner is supplied with a
dedicated airflow proving signal and separate
proved pilot ignition system. All fans must be
running in order for the appliance to proceed to
trial for ignition.
Each MicoFlame® Grande is supplied with the
appropriate wiring diagram showing the actual
staging sequence provided as well as any
special controls or options requested. When
converting
multiple MicoFlame® Grande
appliances to an external sequencing control it is
absolutely necessary to program the sequencer
properly by entering the number of stages
provided on the appliance. In this way the
sequencer will lead/lag or rotate the appliances
properly.
A full diagnostics panel is provided on the
MicoFlame® Grande. On a call for heat, status
lights will light up if the particular safety is
working properly. Once all safeties have been
proved, the appliance will proceed to trial for
ignition and will then sequentially bring on the
burner stages (and the corresponding lights). If
the safety proving sequence does not proceed
to completion, the first safety light to remain off
will indicate the cause of the problem. All other
lights below the problem indicator light will also
remain off.
Burner staging is arranged to allow a minimum
firing rate of no less than 50% in order to
minimize possibility of condensation in the
venting and provide even heat distribution over
the heat exchanger. Staging options are as
follows:
