GENERAL INFORMATION
The ULTRA FLAME DIRECT VENT GAS FIREPLACE is a high-efficiency free-standing
gas appliance with a maximum input rating of 30 000 Btu/h with natural gas or 26,000 Btu/h
with propane. It features a thermostatic modulating valve and a constant pilot. This means that
you can set the height of the flame to your liking by turning the adjusting knob. An optional
thermostat is also available for automatic room temperature control. The valve is also
independent of any exterior electrical supply. Your appliance will therefore continue to heat your
house in the event of a power failure.
For increased efficiency, we offer as an option a 200 CFM blower with speed control and
thermo-switch. Your blower will therefore turn itself on or off automatically if you desire.
Read these instructions and consult your local building authorities before installing this
appliance. Install the unit and its venting system only as described in these instructions.

OPERATION
BEFORE LIGHTING
1) Do not use this appliance if any part has been under water. Immediately call a qualified
service technician to inspect the appliance and to replace any part of the control system and
any gas control which has been under water.
2) Make sure that there are no obstructions in the air intake or venting system.
3) Clear the immediate area of combustible materials, gasoline, and other flammable liquids and
vapours.
4) Make sure that the gas log is in its proper place.
THE FIRST FIRE:
During the first few hours of operation the appliance will release an odor. This is caused by the
burning off of residual oils used in the manufacturing process and by the curing of the high heat
paint. The ceramic glass window may require cleaning after this initial "burn in." Please read
the instructions on cleaning in the MAINENANCE section before doing so.
The optional gold plated items must be
from your fingerprints may permanently etch the gold plating.
If the protective packaging that accompanied the gas log is still in place, follow the instructions
in the LOG PLACEMENT section.
absolutely clean before you light each fire. The acid
LIGHTING PROCEDURE
WARNING: If you do not follow these lighting instructions exactly, a fire or explosion may
result causing property damage, personal injury, or loss of life.
Open the pedestal cover front panel to reach the control.
Make sure the gas control knob is turned to the "off" position. If it is not, press knob slightly and
turn clockwise to the "off" position. Do not force the gas control knob. If the gas control was
in the on position you should wait 5 minutes before trying to re-light the fireplace.
• If you smell gas STOP and follow instructions on the COVER page.
• Push in and turn gas control knob counterclockwise to the "pilot" position.

ULTRA FLAME DV “0” Clearance Fireplace
• Press gas control knob in and hold. Immediately push the red igniter button repeatedly until
pilot flame ignites. Continue holding in the control knob for 5 to 10 seconds, then release it.
If the pilot flame goes out, repeat this step.
• Push and turn gas control knob counterclockwise to the "on" position.
CAUTION: This fireplace is hot while in operation. Do not touch. Keep children, clothing
and flammable materials away.
WALL THERMOSTAT
To operate your ULTRA FLAME using the wall thermostat, follow the lighting procedure and
set the gas control to the ON position. Simply set your wall thermostat to a comfortable
temperature and the fireplace will do the rest.
During the heating season, you do not have to touch the gas control valve. If you would like the
fireplace off for a while, just set the thermostat to its minimum setting. However if you do not
need the fireplace for quite some time, follow the procedure outlined in the SHUTDOWN
section. This will extinguish the pilot light as well.
SHUTDOWN
Push in and rotate the gas control knob clockwise to the "off" position. Do not force.
If you are going to perform any maintenance or cleaning, first allow the fireplace to cool
completely. Follow the instructions in the section on cleaning under MAINTENANCE
INSTRUCTIONS.
BLOWER
The blower control contains a variable speed switch and a thermal switch. When the fireplace is
operating, the thermal switch will turn on at 120° F, allowing the blower to operate . When the
fireplace cools to 90° F, the thermal switch turns off the blower in about 40 minutes. This
prevents the blower from operating when the fireplace is not in use.
The blower not only helps circulate air throughout the room, it also increases the heat output and
efficiency of the ULTRA FLAME.

MAINTENANCE INSTRUCTIONS
TURN OFF THE GAS WITH THE SHUTDOWN VALVE AND DISCONNECT THE
ELECTRICAL POWER BEFORE SERVICING THE APPLIANCE.
The venting system and the gas fireplace should be inspected at least once a year.
Remove the glass front and the logs and clean them if necessary.
The control compartment, air circulating passages, firebox, logs and burner should be cleaned at
least once a year by vacuuming or brushing.
Check the pilot flame to see if it is adjusted properly. Readjust the pilot flame if necessary (as
described below) or clean the pilot orifice if readjustment is not possible.
Check the burner for flame lifting or for unusual flame pattern. If necessary clean the burner
orifice. For more information, see “Adjustments” in the INSTALLATION section.
Keep the area clear and free from combustible materials, gasoline and other flammable vapours
and liquids.
GLASS MAINTENANCE
We have supplied your ULTRA FLAME with special ceramic glass which will withstand the
heat from the unit without cracking. Be careful not to hit the glass.
NOTE:
Never clean this glass with abrasive cleaners.
Use only a cleaner recommended by your dealer.
Never clean glass while it is still hot.
Do not operate the fireplace with the glass broken or removed
For removing your glass front see page 22.
If Your Glass Breaks:
• See your dealer for exact replacement glass.
• Remove front as explained above. With a 5/16” nut driver remove all nuts holding the glass
retainers. Carefully remove retainers and seal.
• After removing all broken glass pieces, insert new glass and reinstall seal and brackets. It the
seal is damaged, replace it with an identical new seal from your dealer.

BURST DISC REPLACEMENT
If the burst disc under the burner moves from its location, it must be put back in place into the
silicone seal. Make sure the switch is depressed all the way during the installation. Otherwise
the appliance will not operate.
WARNING: Never glue or lubricate the disc to the silicone seal. Do not put any object under
the disc.
