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.
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 and are totally harmless
but 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.

7.1.Window Removal
See figure 20.
• Turn the top three spring loaded window bolts through 900to release the window
from the firebox.
• Remove the bottom three spring-loaded window bolts.
• Detach the chain from the top right corner of the window.
• Carefully lift the window away. Keep the window and bolts in a safe place.
7.2. Ignition Spark Check
The pilot burner and electrode unit is at the left 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 21.
7.3.Rear Vent Outlet positioning
If installing with top vent outlet ignore this stage
See figure 22
1. Remove the rear outlet cover plate and seal by unscrewing 12 screws.
Keep the seal and plate for fitting to the top.
2. Remove the top outer vent collar and seal by unscrewing 12 screws.
3. Remove the top inner vent collar and seal by unscrewing 8 screws.
4. Locate the inner collar and seal inside the rear outlet opening. Secure the
inner collar with 8 screws.
5. Fit the outer collar over inner collar. Loosely fit the 12 screws. Place the
Dura-vent adapter #817VAK or Valor terminal unit #551DVK over the
collars to check alignment. Tighten the 12 screws to secure the outer
collar.
6. Fit the cover plate and seal (Removed from the rear) to the top vent
opening with 12 screws.
7.4.# 817VAK Pipe Adapter Fitting
If installing flat on wall with Valor terminal unit #551DVK ignore this
stage.
See figure 23.
1. Fit the Dura-vent adapter #817VAK over the appliance vent collars
pushing on firmly.
2. For rear vent outlet connection, align the adapter so that the seam on
horizontal Dura-vent pipes is not at the bottom – Check by temporarily
fitting a Dura-vent pipe.
3. Drill through the adapter outer tube and appliance outer collar for #6
screws. See figure 40. Make sure that the drill does not penetrate the
inner tubes.
4. Secure the adapter to the outer collar with two #6 thread cutting screws
supplied.

7.5.Top heat shield & Stand-off Fitting
See figures 24 & 25.
1. If installing appliance with top vent outlet remove the plate covering
the vent hole in the top heat shield by unscrewing four screws. If
installing with rear vent outlet, the plate must remain covering the
hole.
2. Remove the screws at the top rear corner of the case sides.
3. If top vent outlet, locate the heat shield over the vent pipe adapter.
4. Support the front of the shield on the two angle supports.
5. Secure the shield to the case sides byrefitting the two screws at the top
rear corners and by two screws from the pack fitted near the front.
6. Bend the two top rear stand-offs and fit to the heat shield with three
screws each – see figure 26.

7.6.Support Angle Fitting
See figure 26
The distance from the wall angles to the front face of the heater case is
adjustable between 3/8” (10mm) and 13/16” (30mm) to allow for a range
of wall finish material thickness (e.g. tile etc).
1. Fit the top angle support to the case top with three screws.
2. Fit the two side angle supports with two screws each. Fit the screws
from inside the heater case.
7.7.Attaching Air Restrictors
No restrictors are required for appliances, which only have a
horizontal vent, run. If installing an appliance, which has rear vent
outlet connection and no vertical vent pipe rise, ignore this stage.
There are three types of restrictor supplied with each #534 engine unit.
They are identified in figure 27.
Type “A” is for horizontal vent termination.
Types “B” & “C” are for through-the-roof termination.
The restrictors cover part of the openings in the firebox rear wall ports –
See figure 28.
The correct restrictors to be fitted for each type of installation are
shown in the table below.
To fit type “A” 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.
To fit types “B” or “C” restrictors remove the top and
bottom screws from the rear ports and fit the restrictors using these screws.

7.8.Attaching Rear Ceramic Support
Fit the rear ceramic support to the firebox back
panel with three screws. See figure 29.
7.9.Attaching to the Framing
1. Place the heater in position in the framing.
2. 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 wall finish but is not fixed to
the framing.
3. 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 30
