A spark ignition system (piezo) allows the gas pilot to be
lit without the use of matches, and permits the operation
of the appliance during a power outage.
This burner system is equipped with an Oxygen
Depletion Sensor (ODS) safety pilot system. The ODS
senses the amount of oxygen available in the room and
shuts the burner system off before the oxygen level
drops below 18%. The pilot can only be relit when fresh
air is available. This may require opening a window
or a door to another room or cracking the damper
open slightly.
This burner system has been certifi ed to two standards:
UNVENTED ROOM HEATER-ANSI Z21.11.2.2-2013
VENTED DECORATIVE APPLIANCE-ANSI Z21.60-2012
Check local or state codes to determine if vent-free
heaters are permitted in your locality before you
install this burner system as a vent-free appliance. If
not permitted, you may install and operate this burner
system as a vented appliance.

and building code acceptances, use ONLY Peterson Real-Fyre® controls, parts, and accessories
