DESCRIPTION
The Series 35-67 is a hot surface ignition system in which
the ignition source is proven to be capable of ignition prior to
the gas valve being opened and is suitable for appliances over
400K BTU. Models compatible to the requirements of ASME
standard CSD-1 are available.
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. The control also
continuously monitors the pressure switch, thermostat and main
burner flame to ensure safe system operation. On-board diagnostics
with LED output provide assistance with troubleshooting to ensure
safe and efficient burner operation.
Agency Certifications
Design certified by CSA International to CAN C22.2 #199-M89 and
ANSI Z21.20 for Automatic Ignition Systems, including UL1998
Software Review.
