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
fire box, 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.

For installations with a horizontal rear termination, the
combination of horizontal and vertical vent pipes must be
within the allowed area shown in Graph 1. A minimum
vertical pipe run of 6” is necessary.
Example a: If a vertical rise of 2ft 3” is required, the
horizontal run must not be more than 11ft 6”.
Example b: If a horizontal run of 3ft 6” is required, the
vertical run must be at least 1ft 3”.
The horizontal vent pipe run may be
redirected by using elbows up to a total of
180º but the maximum horizontal run (E in
figure 5 & graph 1) is reduced by 18” for
every 45º. For example if two 90º elbows are used
as in figure 5a the maximum horizontal run is
reduced by 3ft per elbow –
Total reduction = 6ft.

7.7.Attaching Air Restrictors
There are two types of restrictor supplied with each
#535 engine unit. One type is for installations with
horizontal vent termination and the other is for
installations with through-the-roof termination.
Figure 19 identifies them.
The restrictors cover part of the openings in the
firebox rear wall ports – See figure 20.
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.
7.7.1. 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.
7.7.2. Installations with Through-the-roof Termination
For vent heights up to 20ft. Fit the restrictors at maximum port
opening position.

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 Dura-vent DV GS pipes and elbows up to the wall to check the wall
opening position. See the Dura-vent 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 Dura-vent
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.
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

9. INSTALLATIONS WITH THROUGH THE ROOF VERTICAL
TERMINATION
•Check the roof pitch to determine which roof flashing will be needed
- see vent accessories section 2.4.
•The distance from the roof to the lowest terminal discharge opening
(“H” in figure 25) depends on the roof pitch and must be in
accordance with the Dura-vent instructions supplied with the
termination unit.
Note: The venting system for these appliances is considered to be a
Special Venting System. The rule in the Installation Code requiring
a minimum vent height of 2ft above any portion of a building within
10ft does not therefore apply.
•The minimum clearances to combustible materials all round the vent
pipes must be in accordance with the dimensions shown in section 4
of this manual.
•Drop a plumb from the ceiling to the center of the appliance vent
opening. Mark the position on the ceiling. Drill a small hole at the
marked position.
•Determine the position where the vent will pass through the roof. If
directly above the position where it penetrates the ceiling, drop a
plumb from the roof to the small hole in the ceiling and mark the
roof at this spot.
If rafters or other obstructions will prevent a vertical exit or if clear
attic space is desired, the roof outlet can be offset using 45º elbows -
see fig. 25.
Drill a small hole at the marked position.
•A ceiling firestop must be installed at the second floor and higher
floors.
A ceiling support should be used below the flat ceiling.
To install the firestop & support cut and frame a 10” (254mm)
square hole centered on the small hole previously
drilled - see fig. 26.
•Fit vent accessory elbows and pipe lengths as required
up through ceiling support boxes and firestops.
If installation includes offset, support the offsetting
pipes every 3 feet (1m) with wall straps (fig. 25).
•Cut a hole in the roof centered on the small hole. The
hole must allow for the minimum clearances to
combustible materials - see section 4.
•Fit pipe lengths through the roof. Fit roof flashing
securing it with roofing nails.
•Fit storm collar and termination cap.

See figures 27, 28 & 29
•Feed the switch wires from inside the appliance case through the
opening at the bottom right side of the heater case.
•Route round the back of the valve and connect the two “L” terminals
to the tabs at the left side of the control unit. See figure 27.
•Connect the battery holder to the black connection pad.
•If using the switch extension wires, connect the extension to the wire
harness.
Fit the four 1.5 V batteries. Place the battery holder on the “Velcro”
pad in front of the battery shield. See figure 28.
•
•A standard wall switch box should be secured in the framing to
accommodate the wall switch. If the required location is over 4ft
away from the appliance, an optional #609WEK unit will be required.
•When fitting the wall plate to the wall box, attach the way up shown
in figure 29 so that pressing the upper half of the switch increases the
flames.
10.2. For active remote control with or without active wall
switch
Caution! Don’t connect the batteries in the remote control receiver until
the wires are connected to the burner control unit. A short circuit could
result in destruction of the electrical components.
Feed the switch wires from inside the appliance case through the opening at
the bottom right side of the heater case.

11. GAS SUPPLY INSTALLATION & AERATION SETTING
11.1. Gas Supply Installation
The gas supply pipe should enter the appliance case through the opening at the rear left side. The supply pipe should be
connected to the appliance gas inlet pipe situated at the left side of the control unit. Supply line connection to the inlet
pipe is 3/8”NPT.
If the circulating fan is to be installed, be aware that the supply pipe run inside the case should be at the same height
as the appliance inlet pipe in order to clear the fan. If intending to fit an internal isolating valve, check that it will be
clear of the fan.

•
Use only new black iron or steel pipes or copper tubing if acceptable - check local codes. Note that in USA copper tubing
must be internally tinned for protection against sulfur compounds.
Unions in gas lines should be of ground joint type.
The gas supply line must be sized and installed to provide a supply of gas sufficient to meet the maximum demand of the
appliance without undue loss of pressure.
Sealant used must be resistant to the action of all gas constituents including LP gas. Sealant should be applied lightly to
male threads to ensure excess sealant does not enter gas lines.
The supply line should include a manual shut-off valve to allow the appliance to be disconnected for servicing.
A plugged 1/8”NPT tapping must be installed in the line. The tapping must be accessible for test gauge connection and be
immediately upstream of the gas supply connection to the appliance.
Pressure test the supply line for leaks.
fThe appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of ½psig (3.5kPa).
fThe appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than ½psig (3.5kPa).
fFailure to either disconnect or isolate the appliance during pressure testing may result in regulator or valve damage.
Consult your dealer in this case.
The minimum supply pressure is given in section 3 of this manual.
All piping and connections must be tested for leaks after installation or servicing. All leaks must be corrected
immediately.
When testing for leaks:
fMake sure that the appliance is turned off.
fOpen the manual shut-off valve.
fTest for leaks by applying a liquid detergent or soap
solution to all joints. Bubbles forming indicate a gas
leak. Never use an open flame to check for leaks.
fCorrect any leak detected immediately.
The pressure test tapping locations are shown in figure 34. A
built-in non-adjustable regulator controls the burner
manifold pressure. The correct pressure range is shown in
the table in section 3 of this manual. The pressure check
should be made with the burner alight and the thermostat at
its highest setting. See lighting instruction section for full
operating details.
11.2. AERATION SETTING CHECK
Aeration is factory set.
The setting is non-adjustable for LP appliances.
For natural gas appliances, the shutter is factory set at an aeration gap that
will give optimum performance for the vast majority of installations.
However, in a few unusual installations performance may be improved by
adjusting the aeration. The need for adjustment should be determined by
operating the appliance with the ceramic fuel effects and window installed.
See the “Final checks” section in this manual for adjustment details.
Adjust the aeration by slackening the aeration plate screw and sliding the
plate. In an extreme circumstance, the plate can be totally removed. See
figure 35.
