The BH-Series heater is equipped with a direct
spark ignition system.
Sequence of operation
Turn the thermostat up. When the thermostat
calls for heat, the blower motor will energize.
When the motor approaches nominal running
RPM, the air proving switch closes and activates
the ignition module.
The ignition module then opens the redundant
gas valve and energizes the spark igniter.
When the flame is established, the sparking
sequence ceases.
If the flame is not established during the ignition
sequence, the ignition module closes the gas
valve and purge begins. Module will try two addi-
tional times for ignition (with purge in between). If
ignition is not established, the module will lock
out.
If the flame extinguishes during operation, the
ignition module will provide multiple trial
sequence, described above. If ignition is not re-
established, the module will lock out.
After lockout, control must be reset by turning
down thermostat for five (5) seconds, and then
raising it again to desired temperature, or by dis-
connecting power and then reconnecting.
When thermostat is satisfied, all power to the
unit is shut off.
Pre-Season Maintenance and Annual
Inspection
To ensure your safety and years of trouble-free
operation of the heater, annual inspections by a
contractor qualified in the installation and service
of gas-fired heating equipment and owner are
essential.
Before every heating season, a contractor quali-
fied in the installation and service of gas-fired
heating equipment must perform a thorough
safety inspection of the heater. For best perfor-
mance, the gas, electrical, thermostat connec-
tions, tubing, venting, suspensions and overall
heater condition are some of the areas requiring
inspection.
Please see the chart on pages 18 and 19, for
suggested items to inspect.
