QUALIFIED
AUTOMATIC FLUE DAMPER
• Increases efficiency as it automatically
opens and closes to reduce heat loss in
the standby mode.
ELECTRONIC GAS CONTROL
• Intelligent control logic provides
enhanced operating parameters and
tighter differentials for precise sensing
and faster heating response to optimize
performance.
DIAGNOSTICS
• The electronic gas control incorporates
an LED status indicator that monitors
system operation and service
diagnostics.
ELECTRONIC IGNITION
• Heater operates with an automatic pilot
relight system that shuts off the pilot
during stand-by modes to reduce gas
consumption and eliminates nuisance
pilot outage issues associated with
standing pilot models.
