Ignition Control Functions
When there is a call for heat, and all safeties are
closed, then the combustion air blower starts to purge
air from the combustion chamber. After the pre-purge,
the igniter is energized. The standard ignition module
will lock-out after failing to light 3 times during a call for
heat. To reset the lock-out, press and release the
RESET button located on the user interface. The con-
trol will automatically reset after 1 hour. When in
lock-out the control will run the blower through a post-
purge cycle.
The single-try ignition module (part of the CSD-1
option) will attempt to light only one time before lock-
out occurs. To reset the lock-out, press and relase the
RESET button located on the user interface.
Turning off the power to the heater WILL NOT reset
the single-try ignition module.
High Limit — Manual Reset
The heater is equipped with a fixed-setting manual-
reset high limit temperature device as standard and it
may have an additional optional adjustable manual-
reset high temperature device.

The fixed-setting manual-reset high limit is built into
the PIM, it utilizes a dual-element sensor located on
the outlet (see Fig. 32). To reset a high limit lock-out,

If the water temperature drops below 45˚F on the
Outlet or Inlet sensors, the Boiler pump is enabled.
The pump is turned off when both the Inlet and Outlet
temperatures rise above 50˚F.
If either the Outlet or Inlet temperature drops below
38°F, the VERSA starts the burner at the minimum fir-
ing rate. The burner cycle will terminate when both the
Inlet and Outlet temperatures rise above 42°F.
Controls
WARNING: Installation, adjustment and service of
controls, including timing of various operating func-
tions, must be performed by a qualified installer,
service agency or the gas supplier. Failure to do so
may result in control damage, malfunction, property
damage, personal injury, or death.
