DESCRIPTION

The 35-71 is a 120 VAC direct spark ignition control with
blower relay for controlling a gas valve, controlling and
monitoring combustion air-flow and igniting LP or natural gas
for construction heaters, infrared heaters, crop dryers,
commercial cooking equipment and gas burner applications
that provide a 120 VAC operating signal.
The microprocessor circuit design provides precise, repeatable
timing sequences for ignition times and purge times (pre-,
inter- and post-) as well as multiple tries for ignition, 1 hour
automatic reset and flame sensing during pre-, inter- and post-
purge. The control continually monitors the pressure switch,
thermostat and main burner flame to ensure safe system
operation. The on-board diagnostics with LED output provide
assistance with troubleshooting to ensure safe and efficient
burner operation.
