INTRODUCTION
The Fireplace models covered in this manual
are Direct-Vent sealed combustion vented gas
fireplace heaters designed for residential application. Direct-Vent appliances operate with
the combustion chamber completely isolated
from the inside atmosphere. All air for combustion is brought in from the outside and
exhaust gases are vented through the same
direct vent, vent system.
These appliances feature a comfort control
valve which allows remote control of temperature, fan and flame appearance. These
appliances also use a spark ignitor (piezo)
that allows the appliance's pilot gas to be lit
without the use of matches. This system
provides continued service in the event of a
power outage.
The external electrical power (120v) is required to operate the provided circulating
blower.
These appliances comply with National Safety
Standards and are tested and listed by OmniTest Laboratories (Report No. 116-F-02-5) to
ANSI Z21.88-2002 (in Canada, CSA-2.33-2002),

Glass Cleaning
It will be necessary to clean the glass periodically. During start-up it is normal for condensation to form on the inside of the glass. This
can cause lint, dust and other airborne particles to cling to the glass surface. Also initial
paint curing may deposit a slight film on the
glass. It is therefore recommended that the
glass be cleaned two or three times with a nonammonia household cleaner and warm water
(a gas fireplace glass cleaner is recommended).
After that the glass should be cleaned two or
three times during each heating season, depending on the circumstances present.
Note: Clean glass after first two weeks of
operation at least once. In some environments,
it may be necessary to clean the glass several
times during the first weeks of operation.
WARNING: DO NOT USE ABRASIVE
CLEANERS. NEVER CLEAN THE GLASS
WHEN IT IS HOT.
CAUTION: DO NOT ATTEMPT TO TOUCH THE
FRONT ENCLOSURE GLASS WITH YOUR
HANDS WHILE THE FIREPLACE IS IN USE.
Figure 6
Maintenance
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician. However, more frequent periodic inspections and cleanings should be performed by
the homeowner. Homeowner must contact a
qualified service technician at once if any
abnormal condition is observed.
Refer to the maintenance schedule for maintenance tasks, procedures, periodicity and by whom
they should be performed. Always verify proper
operation of the appliance after servicing.

Burner Adjustments
The following paragraphs address burner adjustment concerns and procedures.
Flame Appearance and Sooting
Proper flame appearance is a matter of taste.
Generally most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large will
exhibit flames that are blue and transparent.
These weak, blue and transparent flames are
termed anemic. If the air shutter opening is too
small sooting may develop.
Sooting is indicated by black puffs developing
at the tips of very long orange flames. Sooting
results in black deposits forming on the logs,
appliance inside surfaces and on exterior surfaces adjacent to the vent termination. Sooting
is caused by incomplete combustion in the
flames and a lack of combustion air entering the
air shutter opening.
To achieve a warm yellow to orange flame with
an orange body that does not soot, the shutter
opening must be adjusted between these two
extremes. No smoke or soot should be present.
Reposition the logs if the flames impinge on
any of them.
If the logs are properly positioned and sooting
conditions exist, the air shutter opening on the
main burner tube should be adjusted. Normally,
the more offsets in the vent system, the greater
the need for the air shutter to be opened further.
WARNING: AIR SHUTTER ADJUSTMENT
SHOULD ONLY BE PERFORMED BY A
QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
ENSURE THAT THE FRONT GLASS PANEL IS IN
PLACE AND SEALED DURING ADJUSTMENT.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Adjustment
CAUTION: THE AIR SHUTTER ADJUSTMENT
ROD (
SEE FIGURE 8
ANCE SURFACES ARE HOT. EXERCISE CAUTION TO AVOID INJURY WHILE ADJUSTING
FLAME APPEARANCE.
To adjust the flame, restate the air shutter
adjustment rod toward the back or toward the
front of the fireplace (rod located in the lower
control area). Position the air shutter to the
factory setting as shown in the Table of
8
. Allow the burner to operate for at least 15
minutes. Observe the flame continuously. If it
appears weak or sooty as previously described,
adjust the air shutter by pushing or pulling on
the adjustment rod until the flame appearance
is as desired.
The air shutter adjustment rod and associated
adjustable air shutter is patented technology.
Flame adjustments can be made quickly and
accurately to taste without the need of disassembling the appliance and waiting for 30 minutes after each adjustment.
Propane models may exhibit a flame pattern
that may candle or appear stringy. If this is
problematic or persists as the appliance is
continually operated, adjust the air shutter
closed as described in the previous paragraphs.
Operate the appliance for a period of time as
the effect diminishes, ensuring that the appliance does not develop sooty flames.
