high pressures! Apply soapsuds (or a liquid deter-
gent) to each joint. Bubbles forming indicate a leak.
Correct even the slightest leak at once.
If you connect natural gas to an LP gas unit, you may
be unable to ignite the pilot. If the pilot does ignite, the
front burner flame on the low setting will be bright blue
but only 1/4" to 1/2" long and most likely lifting off the
burner ports. If this is the case, turn the unit off immedi-
ately.
If you connect LP gas to a natural gas unit, the front
burner flame on the low setting will be about 6" - 8"
long. On the medium and high setting, the front burner
flames will be bright yellow and about 10" in length.
Turn the unit off immediately! If the unit is allowed to
run in this condition, substantial amounts of soot will be
generated and emitted into the house.
Gas Pressure Check
The gas inlet pressure specified in Table 1 is the
pressure where the field-installed gas line connects to
the gas control. This is measured at the inlet test port
on the gas valve in the appliance. Ensure that pressure
is as shown in Table 1.
The manifold pressure is controlled by a regulator built
into the gas control and should be checked at the
pressure test points located between the flame adjust-
ment knob and the control knob at the front of the
valve. The pressure connections accept 1/4” I.D. hose
or tubing.
The pressure should be checked with the appliance
burning on high (highest setting) and all other gas
appliances turned on. One must then read the manom-
eter and if pressures are not 10"w.c. for LP or 3.5" for
natural gas, then the inlet pressure must be adjusted or
increased until the proper pressures are attained. If
these pressures are greater than 10"w.c. for LP or
3.5"w.c. for natural gas, contact your gas supplier
before operating the appliance.

Log Installation
With gloves, remove each of the logs by gripping at
either end while avoiding any undue pressure. The logs
are made from light-weight ceramic fiber and may break
if undue force is applied.
The carton contains the following items: front log, back
log, center twig and a bag of volcanic ash.
Positioning the Logs
(Refer to Figure 8)
•
Position the rear log so the bottom of the log slides
through the large retangular hole behind the burner.
•
Postion the front log so it is centered left to right and
between the rear log and the grate bars. Carefully
push the front log down until the bottom of the log
makes contact with the grate bars. The charred
area should be centered between the outermost
grate bars.
CAUTION: If the appliance’s operating pressures
are not checked and adjusted, improper combus-
tion may result in soot being produced.
The pressure regulator is preset and locked to prevent
tampering. If the pressure is not as specified, replace
the regulator with part # 73332 (for natural gas only), or
part #73333 (for L.P. gas only).
After measuring the pressure, replace the test point
plug and check for leaks. Replace the control box
cover and the two phillips head screws.
