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.
Keep curtains, clothing, furniture, and other
flammable materials a safe distance from all parts of
the appliance and its vent system.
Keep the appliance area well clear and free from
combustible materials, gasoline and other flammable
vapors and liquids.
Never attempt to burn paper or any other material in
the appliance.
The venting terminal must not be recessed into a wall
or siding.
The vent terminal on the outside wall must be kept
free from obstructions. No objects should be placed
within 2 feet (60cm) of the vent terminal. The terminal
is hot during operation and requires a guard if it is
accessible to any person. An approved Valor guard is
available from your dealer.
During extreme weather conditions ensure that the
vent outlet is free from ice and snow before attempting
to light.
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.
Should you encounter an operational problem, call
your dealer immediately. Do not try to repair the unit
as you may cause an injury or damage the fireplace.
NOTE
When operating your new fireplace for the first time, some vapors may be released due to the burning of curing compounds
used in the manufacture of the appliance. They may cause a slight odor and could cause the flames to be the full height of the
firebox, or even slightly higher, for the first few hours of operation. It is also possible that these vapors could set off any
smoke detection alarms in the immediate vicinity. These vapors are quite normal on new appliances. You may wish to open
windows into the room to reduce the vapor/odor build up. After a few hours use the vapors will have disappeared and the
flames will be at their normal height.
During the first hour of use, the ceramic firebox walls may go a smoky color. This is not soot. It is a temporary effect lasting
only while the ceramic material becomes stabilized. The walls will revert to their initial color after your fire has been used for
one or two hours.
State of California. Proposition 65 Warning. Fuels used in gas, wood-burning or oil fired appliances, and the
products of combustion of such fuels, contain chemicals known to the State of California to cause cancer, birth defects
and other reproductive harm. California Health & Safety Code Sec. 25249.6.

To fit the restrictors, remove the center screws
from the rear ports and fit the restrictors using
these screws. To set the restrictors at maximum
port opening, slacken the bottom screws in the
ports, slide the restrictors down as far as possible
and tighten the screws over the restrictors.
To set the restrictors at minimum port opening,
slide the restrictors up as far as possible and tighten
the screws.
7.6.1. Installations with Horizontal Termination
Do not fit restrictors if the vertical rise is less than 3ft.
Do not fit restrictors if the horizontal run is more than 4ft.
For installations with a horizontal run of 4ft or less and having a
vertical rise of 3ft or more fit the restrictors at maximum port opening
position. See Graph 2.
On models 535 the horizontal type restrictors are never set at any
position except maximum port opening.
7.6.2. Installations with Through-the-roof Termination
For vent heights up to 20ft. Fit the restrictors at maximum port
opening position.
For vent heights above 20ft Fit the restrictors at minimum port
opening position.
7.7. Attaching Rear Ceramic Support
Fit the rear ceramic support to the firebox back panel with three
screws. See figure 21.
7.8. Attaching to the Framing
•Place the heater in position in the framing.
•Secure the side support angles to the side studding through
two holes each side with the woodscrews supplied. The top support angle should abut the cement board but is not fixed
to the framing.
•Check the wall finish requirements with the homeowner. If necessary, adjust the position of the heater so that the
distance from the front of the heater case to the angles is suitable for the thickness of the wall finish (e.g. tile, etc.) – see
figure 21a.

8. INSTALLATIONS WITH HORIZONTAL TERMINATION – INSTALLING
TO WALL
See section 4 for full range of horizontal termination applications.
8.1. Wall Opening
•Fit all the required pipes and elbows up to the wall to check the wall
opening position. See the manufacturer’s instructions supplied with
the sections.
•Make Wall Opening.
If the wall is constructed of solid non-combustible materials and has no
combustible surface cladding (including wood) inside or outside then
the wall plates or thimbles will not be required.
If the wall has combustible material, mark the wall for a 10”x10”
square. If the wall is totally non-combustible (e.g. masonry block or
concrete) mark for a 7” circular hole. In both cases, the center of the
hole should line up with the centerline of the horizontal vent. (see
figure 24)
8.2. Valor Terminal #551DVK - Preparing Wall Plates
The wall plates are not used for 7” hole in non-combustible walls.
1. Bend the wall shields and screw to the inside of the wall plates with
6 thread cutting screws per plate. See figure 22.
2. Bend the inner wall plate tab as shown in figure 23 so that the seam
on the terminal tube will pass
clearly through the plate with
the wall shield at the top. Place
the inner wall plate over the
terminal unit.
3. Slide the terminal into the wall.
Make sure that the drain hole is
at the bottom – the seam will be
through the notch in the wall
plates – See figure 24.
4. Slide the inner wall plate up to
the wall. Mark the four holes
for the wall screws. Slide the
plate away.
5. Drill and plug the wall.
6. Screw the plate to the wall with
4 screws provided.
7. Bend the outer wall plate tab as
shown in figure 23.
8. Place the outer wall plate over the terminal unit. Slide the wall plate up to the wall. Mark the four holes for the wall
screws. Slide the plate away.
9. Drill and plug the wall.
10. Screw the plate to the wall with 4 screws provided.
See figure 24.

Important Installer Notice – Weather Sealing & Vapor Barriers
It is the installer’s responsibility to ensure that vent installations through exterior walls are caulked and weatherproofed in
such a manner as to:
• Prevent rain water from entering the wall from the weather side by adequately caulking the outer vent plate to the
exterior wall surface.
• Prevent moisture inside the home from penetrating into the wall structure by ensuring the inside wall plate is
adequately sealed to the inside vapor barrier.
• Prevent rain water and moisture from entering the walls by sealing the joints between the outer vent tube and the inner
and outer wall plates.
We recommend the use of a high quality polyurethane sealant.
