GENERAL INFORMATION
TheseUnventedGas Log RoomHeatersincor-
porate unitized ceramic fiber logs which glow
realistically when the heater is operating.
The log sets covered in this document are
manually controlled heater rated units. These
unitsareequippedwitheitherastandardmanual
gas valve or a millivolt gas valve. The control
knobissettothedesiredposition,whichmain-
tains a continuous gas burning rate.
A spark ignition system (piezo) allows the gas
pilot to be lit without the use of matches or
batteries and permits operation of the heater
during a power outage.
These heaters are fitted with a specially de-
signed pilot utilizing an oxygen depletion sen-
sor (ODS) which responds to the amount of
oxygen available in the room and shuts the
heater off before the oxygen level drops below
18%. Thepilot can berelit only when fresh air
is available. Refer to the Combustion and Ven-
tilation Air section.

unusually tight construction provided the
space is unconfined, or if confined, is pro-
videdwithtwopermanentopenings commu-
nicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 (latest edition),

Step 2. Connecting Gas Line – Aqualified gas
applianceinstallermust connect thegasroom
heater to the gas supply.
Consult all local codes.
Route gas line using techniques and materials
prescribedbylocaland/ornationalcodes.Only
use pipe of ¹⁄₂" or greater diameter to allow full
gas volume to the gas fireplace. Undue pres-
sure loss will occur if the pipe is too small.
An ANSI approved manual shut-off valve and
unionmustbeinstalledupstream of theheater
within the fireplace cavity when rigid pipe is
used.
Ensure that a sediment trap is installed up-
stream of the heater within the structures
piping system to prevent moisture and con-
taminants from passing through the pipe to
the heater controls and burners ( Figure 9 ).
Failureto do socould prevent the heater from
operating reliably.
IMPORTANT: HOLD HEATER REGULATOR

for connection to the inlet.
When tightening up the joint to the regulator
hold the regulator securely with a wrench to
prevent the regulator from moving.
Checking Gas Connections: Turn on gas sup-
ply and test for gas leaks using a gas leak test
solution (also referred to as bubble leak solu-
tion). NOTE: using a soapy water solution
(50%dishsoap,50%water)isaneffectiveleak
test solution, but it is not recommended, be-
causethesoapresiduethatisleftonthepipes/

A. Light the appliance (refer to the lighting
instructions label in the control compartment
or on pages 12 or 14).
B.Brushalljointsandconnectionswiththegas
leaktest solutionto check for leaks. If bubbles
are formed, or gas odor is detected, turn the
gas control knob (off/pilot/on) to the “OFF”
position. Either tighten or refasten the leaking
connection, then retest as described above.
C. When the gas lines are tested and leak free,
be sure to rinse off the leak testing solution.
