Each heater includes a unitized set of ceramic
fiber logs. The heater and logs are assembled
as shown in
Figure 11. Handle these logs with
great care. The logs can be easily damaged, but
when handled properly they can provide years
of performance and enjoyment.

Gas Pressure Check
The heater regulator controls the burner pres-
sure which should be checked at the pressure
test point (
¹⁄₈
" NPT plugged tap) located at the
bottom of the regulator (on manual models) or
on the control valve itself (on Millivolt mod-
els), identified A for the manifold side and E for
inlet pressure. Ensure operatilng pressures
are within the limits specified in the techinical
chart on page 10.
Figure 10
The pressure should be checked with the gas
heater burning and the control set to high (3).
The pressure regulator on manual models is
preset and locked to avoid tampering. If the
pressure is not as specified in the Technical
Details Chart on page 10, replace the regulator
with P/N 110351 for natural gas and P/N
110352 for propane (L.P.G.) heaters.
Replace the test point plug after pressure
measurement ensuring no gas leaks.
Step 3. Secure the log set within the firebox
using the screws and drilled holes discussed
in Step 2.
Step 4. Assembling the Logs
WARNING: DO NOT ADD EXTRA LOGS OR
ORNAMENTS SUCH AS PINE CONES, VER-
MICULITE OR ROCK WOOL. USING THESE
ADDED ITEMS CAN CAUSE SOOTING.

Periodically check the positioning of all logs.
Flame Appearance
REFER TO THE OPERATING INSTRUCTIONS
LOCATED AT THE BACK OF THIS MANUAL
BEFORE LIGHTING THE HEATER TO OBSERVE
THE FLAMES.
Flames from the pilot, front and rear burner
should be visually checked as soon as the
heater is installed. In addition a periodic visual
check of the flames should be made. The pilot
flame should always be present when the heater
is in operation (
Figure 12 ).
WARNING: NO ADJUSTMENTS ARE TO
BE MADE TO THE ODS PILOT SYSTEM.
TAMPERING WITH THIS SYSTEM CAN
BE EXTREMELY HAZARDOUS.
Figure 12
An incorrect pilot flame pattern is shown in
Figure 13. This pilot flame will cause the
thermocouple to cool. When the thermocouple
cools, the log set will shut off. If pilot flame
pattern is incorrect, or if log set shuts off,
contact your service representative.

WARNING: FAILURE TO POSITION THE
PARTS IN ACCORDANCE ITH THESE DIA-
GRAMS OR FAILURE TO USE ONLY PARTS
SPECIFICALLY APPROVED WITH THIS
HEATER MAY RESULT IN PROPERTY
DAMAGE OR PERSONAL INJURY.
WARNING: DO NOT PLACE ANY LAVA
ROCK ON LOGS OR BURNERS. THIS MAY
CAUSE SOOTING. ONLY PLACE LAVA
ROCK ON FLOOR OF FIREPLACE.
