Start-Up
Step 6 Set the Maximum Firing Rate (...continued)
While monitoring the units temperature rise, set the maximum firing rate by adjusting the regulator (as shown
below) until the designed temperature rise is achieved. After setting the maximum firing rate, reconnect the wire
to the amplifier.
IMPORTANT!
Setting the maximum firing rate during mild
weather conditions may cause the high limit to
trip out during extreme conditions requiring
manual resetting.
NOTE!
Gas trains are equipped with either separate
regulators and modulating valves or with a
combined modulating regulator.
NOTE!
Clockwise rotation increases the temperature rise, counterclockwise rotation decreases the
temperature rise.
