1. SAFETY INFORMATION
WARNING: Do not operate the appliance with the glass
front removed, cracked or broken. Replacement of the
glass should be done by a licensed or qualified service
person.
(The whole window unit may be temporarily removed by
the owner for cleaning the interior of the firebox, etc.)
Only the authorized Valor replacement window unit listed
in the repair parts booklet must be fitted - never use
substitutes.
If the glass is damaged search inside and adjacent to the
appliance for any glass fragments.
Due to high temperatures, the appliance should be located
out of traffic and away from furniture and draperies.
Children and adults should be alerted to the hazards of
high surface temperatures and should stay away to avoid
burns or clothing ignition.
Young children should be carefully supervised when they
are in the same room as the appliance.
Clothing or other flammable material should not be
placed on or near the appliance.
This appliance must be installed and repaired by a
qualified service person. The appliance should be
inspected before use and at least annually by a professional
service person. More frequent cleaning may be required
due to excessive lint from carpeting, bedding material, etc.
It is imperative that control compartments, burners and
circulating air passageways of the appliance are kept
clean.This appliance should be installed and repaired by a
qualified service person.
Keep curtains, clothing, furniture and other flammable
materials a safe distance from all parts of the appliance.
Keep the appliance area well clear and free from
combustible materials, gasoline and other flammable
vapors and liquids.
If any changes are made to the room construction in the
vicinity of the appliance after installation (e.g. additional
mantle etc.) make sure that the changes conform to the
installation requirements in this manual.
Never attempt to burn paper or any other material in the
appliance.
Keep the base of the appliance clear to prevent obstruction
of air flow to the appliance.
This appliance must be properly connected to a venting
system. It is equipped with a vent safety shutoff system.
Operating when not connected to a properly installed and
maintained venting system or tampering with the shutoff
system can result in carbon monoxide (CO) poisoning and
possible death.
The venting system should be checked periodically.
Recent trends in home improvement and new tighter
construction techniques have contributed to problems
with venting. If you suspect that your appliance is not
venting properly, do not operate. Seek expert advice.
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.
NOTE
When operating your new furnace for the first time, some vapors may be released which may cause a slight odor and could possibly set off any smoke
detection alarms in the immediate vicinity. These vapors are quite normal on new appliances. They are totally harmless and will disappear after a few
hours use.

4. LOCATION IN THE ROOM
The appliance can be installed in the following constructions:
2.1 Solid fuel (Non-combustible) fireplaces
As supplied, this appliance can be installed as an inset in an existing solid fuel type fireplace with a chimney and 3" dia liner (see
fig.1a).
The fireplace must be built in accordance with the national, state provincial or territorial building code recognized by the
authority having jurisdiction, or in the absence of such a code, in accordance with the National Building Code of Canada or the
National Fire Protection Association code in the USA The size of the fireplace recess must be sufficient to accommodate the
appliance case as shown in fig.1a.
The chimney must be swept and both chimney and fireplace checked for soundness before installation of the appliance. The liner
must be a type approved by the enforcing authority and installed in accordance with the manufacturer's instructions.
The appliance must be installed on a non-combustible floor. The floor must be sufficiently flat and level to support the appliance
satisfactorily. Some fireplace constructions have a well in the floor at the back that may need to be filled in. In the USA it is
mandatory that a hard surfaced non-combustible hearth area must be maintained at least 16" in front of the fireplace. This may be
finished in brick, ceramic tile, marble,etc. Raising the hearth slightly will help to minimize dust and lint accumulation under the
unit.
In Canada, though not mandatory, we recommend that carpet, soft vinyl or other combustible floor coverings are kept at least 16”
from the front of the furnace since these types of materials may be affected by the high radiant heat output from this appliance.
The minimum clearances from any combustible constructions at the front of the appliance are shown in fig.1b. These front
clearances apply for all installations.
2.2 Enclosures constructed with combustible materials
#770ZCK Zero clearance kit must be installed where the furnace is intended to be in an enclosure made with wood studding or
other combustible materials.
The enclosure framing requirements are shown in figures 1c through 1f.
Note that in Canada, though not mandatory, we recommend that carpet, soft vinyl or other combustible floor coverings are kept
at least 16” from the front of the furnace since these types of materials may be affected by the high radiant heat output from this
appliance.

7. INSTALLATION
7.1. Pre-installation preparation
For installations in enclosures constructed with
combustible materials, complete the enclosure and install
the #770ZCK zero clearance kit in accordance with the
instructions supplied with the kit.
7.1.1 Closing Large Fireplace Openings
This appliance is suitable for solid fuel fireplace openings
within the sizes shown in figure 1a. Larger fireplace
openings may be reduced or the outer surround plate
extended using non-combustible materials.
Fig. 3 Window removal (Shown with Standard Front Frame)
7.1.2 Remove Window and Logs (see fig.3).
• Detach the window unit by removing the two screws
situated at the bottom corners of the unit.
• Lift the window unit up and forwards to unhook the
top. Put the window in a safe place.
• Take the ceramic logs out of the firebox and store in a
safe place.
7.1.3 Check Ignition Electrode Spark.
The pilot burner and electrode unit is at the right end of the burner.
Push in the lighting knob and turn counter-clockwise through the
“IGN” position to “PILOT”. A spark should flash across from the pilot
electrode to the pilot burner shield. See figure 4.
7.1.4 Check flame control motor.
• Fit the four batteries into the battery box (Which is attached to the
switch wires).
• Temporarily connect the black connector pad to the control unit –
See figure 5.
• Operate the switch. This should cause the flame control knob to
rotate counter-clockwise. See figure 5.
• Disconnect and remove after checking.
7.1.5 Remove the Vent Connection Unit.
Detach the vent connection unit from the top of the appliance case by
removing the screw at front. Slide the vent connection unit back and lift clear (see fig.6).
