G18 SPECIFICATIONS AND REQUIREMENTS
The minimum size of fi replace for installation of the Real-Fyre
®
G18-2 heater gas log set (refer to Fig. 3-1):
The G18 series vent-free gas log sets are available with
a variable fl ame height control valve that can be used
with a remote transmitter and receiver (not included
with model numbers ending in M or MP).
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 vent-free gas log set is equipped with a pilot safety
system with ODS (Oxygen Depletion Sensor). The ODS
senses the amount of oxygen available in the room
and shuts the log set 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 gas log set has been certifi ed to two standards:
UNVENTED ROOM HEATER-ANSI Z21.11.2b-2007
VENTED DECORATIVE APPLIANCE-ANSI Z21.60b-2004
Check local or state codes to determine if vent-free
heaters are permitted in your locality before you install
this log set as a vent-free appliance. If not permitted,
you may install and operate this log set as a vented
appliance.
This unit may not be installed in a vented fi replace with
a chimney of less than 15 feet in height.
Observing minimum fireplace dimensions and
centering the appliance in the fi replace will assure
adequate clearance for operation and servicing. It may
be necessary to un-install the unit for some types of
service.
