1.1 CLEARANCES:
Make sure that the minimum clearances to combustible materials
are maintained during installation including adequate space for
the proper operation and servicing of the heater. The minimum
clearances from the heater to combustible materials are shown in
figure 1. The combustion air opening below the ashlip assembly
and the clearance at the sides of the case rear must not be
obstructed.
ensure that no sags or dips are allowed to occur where the liner
connects to the heater (figure 2).
2. Free standing with connection to an approved chimney or vent
maintaining the clearances shown in figure 1.
3. As a zero clearance installation fitted with the optional
#401CVK Concealed Venting Kit.
This kit allows the heater to be installed with a type B metal vent
concealed behind a wall or partition and/or in a chase. The
venting kit is designed for a 4” round flue. The kit is shown in
figure 3.
Clearances to combustible materials are: Outside edges of
framing plate = 0”. From any part of the flue adapter box
= 1”. Clearances from the connecting elbow are
determined by local codes or, in the absence of local codes,
with the current CAN/CGA1-B149 Installation Code in
Canada or the current National Fuel Gas Code, ANSI
Z223.1 in the USA
1.2 FLOOR:
Do not place the heater on carpeting, vinyl or other soft surfaced
floor coverings. Install only on hard surfaced materials.
It is recommended for aesthetic considerations and ease of
maintenance that the heater is installed on a hearth finished with
brick, ceramic tile, marble etc. Raising the hearth slightly will help
to minimize dust and lint accumulation under the unit. The
recommended minimum hearth size is 32” wide x 15” deep.
If however, the heater is installed directly on flooring of
combustible material other than wood, it must be installed on a
metal or wood panel extending the full width and depth of the
heater.
1.3 DRAFT HOOD:
This heater has a draft hood built into its back and draws its air
from either side. It must not be altered or obstructed. The draft
hood must be in the same atmospheric pressure zone as the
combustion air inlet to the heater.
1.4 VENTING:
This heater is a vented appliance and must be connected to a
chimney or flue in accordance with the national and local codes.
For added safety, this heater is equipped with a vent sensor system
which will react to incorrect venting by shutting down the gas
supply. The thermally activated sensor switch is located within
the draft hood to detect either a blocked or disconnected vent.
Certain backdraft conditions may also activate the switch.
1.5 OPTIONAL ACCESSORIES:
The following kit can be used with this appliance:#401CVK Concealed Vent Kit required for use with a new zero
clearance type installation. It allows the heater to be installed with
type B metal vent concealed behind a wall or partition and/or in a
chase.
Full installation and operating instructions are supplied with the
kit.

1.6 POSSIBLE INSTALLATIONS
This appliance can be installed:
1. As a retrofit
a. To an existing masonry fireplace and chimney
b. To an existing factory built zero clearance type fireplace with a
factory built chimney.
The fireplace must be built in accordance with the national, state,
provincial or territorial building code recognized by the authority
having jurisdiction, or the National Fire Protection Association
code in the USA
Any flue damper must be removed or locked open.
The chimney must be swept and both chimney and fireplace
checked for soundness before installation of the heater.
If local codes dictate or if condensation is a problem, a flue liner
must be installed. Use a flue liner that is approved by the
enforcing authority and that is installed in accordance with the

If installing to #401CVK Concealed Vent Kit
When installing the Valor President to the #401 Concealed Vent
Kit, the vent collar does not penetrate sufficiently into the flue
adaptor box to ensure good extraction of the combustion
products. The collar extension assures good extraction.
If the Valor President is not being installed to the #401
Concealed vent kit don’t use the extension.
Fitting the extension (See figure 8A):
• Make the extension into a coil small enough to fit inside the
vent collar.
• Push the coiled extension right into the vent collar as far as it
will go.
• Release the extension so that the coil expands against the
inner diameter of the collar.
• Seal the joint between the collar and extension all round with

point.
The
appliance is
supplied
with a
3/8”NPT
elbow
Fig. 10 Firebox floor panel removal
connector
for connection to the supply pipe.
Use only new black iron or steel pipes or copper tubing it
acceptable - check local codes.
Note: 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 L.P 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 and
union in the line for safety and to allow the appliance to be
disconnected for servicing.
Pressure test the supply line. The 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 1/2psig (3.5kPa).
The 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 1/2psig (3.5kPa).
All piping and connections must be tested for leaks after
installation or servicing.
All leaks must be correct immediately.
When testing for leaks:(a) Make sure that the appliance control knob is at the OFF
position.
(b) Open the manual shut-off valve
(c) Test 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
(d) Correct any leak detected immediately. Refit the firebox floor
panel when testing results are satisfactory.
The pilot
electrode is
situated at the
right side of the
firebox above the
rear port of the
pilot and cross

Check that there
is an ignition
spark at the pilot
port.
Fit the control
knob over the
control valve.
To initiate a spark
Fig. 9 Pilot ignition system
depress the
control knob.
While keeping it depressed, turn counter clockwise until the click
of the spark igniter is reached.
If there is no spark produced during several attempts, check that
the electrode lead is properly connected to the electrode and that
the spark gap is correct. Replace parts, if necessary, as described in
the relevant servicing sections of this manual.
6. INSTALL THE FIRE
To prevent hearth damage, two plastic caps are included in the
accessory pack. Fit these caps over the heads of the leveling screws
in the front feet.
Level the fire by slackening the two lock nuts and turning the
leveling screws in the front feet up or down as required while they
bear on the hearth. When the fire is level and square to the wall,
retighten the lock nuts.

8. LOG INSTALLATION
8.1 Place the rear log (the log with only one short stub)
in the retaining cradle behind the rear burner tube with
its back against the firebox back wall (fig. 11). The short
stub should be at the top right of the log. Center the
log so that the gap to the firebox walls is the same at
each side.
8.2 Place the front log on the retaining cradles between
the rear and front burner tubes (fig. 12). Center the log
so that the gap to the firebox walls is the same at each
side.
8.3 Place the cross log in position (see fig. 13). The
front of this log is indicated by the letter “F” embossed
on its underside. Make sure that the front of the log is
seated inside the follow in the front log and is not raised
in front of it.
8.4 Replace the window unit. Locate its bottom edge in
the support channels at the firebox sides. Refit the
knurled screws at the sides near the top.

9. CHECK APPLIANCE OPERATION
Depress the control knob. Turn counter clockwise until resistance
is felt just before the piezo-electric ignition is activated. Keep the
knob depressed for a few seconds to purge air from the gas lines.
When it is judged that the air has been purged keep the knob
depressed and turn to the ignition position. A spark should be
produced which should ignite the pilot and cross lighting burner.
When ignition has been achieved, keep the control knob depressed
for approximately five seconds to allow the thermocouple probe to
warm up then release it. It the burner does not remain alight,
ensure that the air has been purged.
Check that the burners are correctly alight at the four settings on
the control valve as shown in the following table:Control knob Burner appearance

The burner manifold pressure is controlled by a built-in non
adjustable regulator. The manifold pressure should be checked at
the pressure test point which is located immediately downstream
of the regulator (i.e. located above the regulator). The pressure
check should be carried out with the fire alight and the control
knob at the full on position. The pressure setting should be
within the limits shown in the table.
If the pressure reading at this test point is incorrect but the supply
system pressure is correct when measured at the test point
upstream of the regulator, then the regulator is faulty and should
be replaced. After checking the pressure, turn off the fire, remove
the pressure gauge and replace the pressure test sealing screw. Test
the sealing screw for gas soundness.

11. CHECK FOR CORRECT VENTING
A CHECK FOR CORRECT VENTING OF COMBUSTION
PRODUCTS MUST BE MADE BEFORE THE INSTALLED
HEATER IS LEFT WITH THE CUSTOMER. THE TEST
SHOULD BE MADE IN THE FOLLOWING MANNER
Light the heater and set the control to the full on position.
After the appliance has been alight for five minutes place a lighted
smoke match or taper at the right side of the case level with the
opening of the smoke channel - see figure 14.
The installation is satisfactory if the majority of the smoke is
drawn into
the draft
diverter.
If the vent is
blocked or
has strong
reverse flow,
the thermally
actuated
switch
mounted in
the draft
diverter
opening will
automatically
shut off the
gas supply
within about
five minutes. Fig.14 Venting check
If most of the
smoke is not drawn in, leave for about ten minutes and then try
again.
If the majority of the smoke is still not drawn into the draft
diverter, turn the heater off and check cause of lack of draft, if
necessary get expert advice.
Turn off after checking. To turn off, Push the control partially
in, turn clockwise and release the knob. If any resistance is
experienced at the ignition position, release the knob before
turning to the off position.
Note: If the fire is turned off while hot, wait three minutes before
relighting.

12. AERATION ADJUSTMENT (See Fig. 15)
Natural gas appliances have adjustable shutters to control primary
aeration on both rear and front burner tubes.
Propane appliances have an adjustable shutter on the front burner
tube only. The
air holes are at
the right side of
the tubes. The
appliances are
supplied set at
maximum
aeration. For
the majority of
installations no
adjustment will
be necessary.
However, in a
few instances,
performance
may be
improved by
reducing the
aeration by
sliding the
shutters to the
left or right.
Evaluate the
aeration only
after the heater
has warmed up
(approximately
Fig. 15 Aeration shutters
15 minutes).
Decreasing
aeration will cause the flames to appear more yellow or Orange
revealing less glow in the logs. Too little aeration may result in
black carbon forming and dropping into the firebox.
Take the cast-iron
Arched Lintel
component and
observe the fixing
attachments on the
rear, and towards
the inside top of the
Side Panels (Figure
17).
13. COMPLETION OF THE CAST-IRON OUTER CASE
ASSEMBLY
Lifting carefully, place the entire Side Panel/Ashlip assembly onto
the hearth in

point and drop the
lower hinge pin into
the hole provided.
Holding the door
using one hand,
carefully lift up the
right hand side of
the arched lintel
component (Figure
19) and offer up the
door to a position
below the top hinge,
which is mounted
on the arched lintel.
Allow the hinge pin
Fig. 19 Door hinge attachment
in the arched lintel
to locate into the
door hinge, by carefully lowering the arched lintel into position.
The door should hinge freely. Close the door.
Offer up the arched
lintel component to
the side panels in
turn, and locate
onto the
attachments in the
side panel (Figure
Fig. 17 Arched lintel attachment points
18).
The sheet metal
component attached to
the rear of the arched
lintel should sit on top
of the horizontal front
section of the heater
convection hood.
Ensure the Arched
Lintel is a good fit,
adjusting the location of
the side panels slightly if
necessary.
Take the cast-iron door,
and observe the hinges
on the right hand side,
looking from the front.
Offer up the door to the
Fig. 18 Arched lintel installation
ashlip assembly hinge
Fig. 16 Outer case & firebox relationship
11
The Outer Case assembly can now be attached to the Heater.
Locate the bolts and washers supplied, and fasten the Arched
Lintel to the top surface of the Heat Engine as shown in Figure
20. Ensure the sheet metal components fit closely together, or
adjust the Arched Lintel attachment points for height as shown in
Figure 21 until they do so.
Observe the correct operation of the door. Using the handle, lift
the door slightly so that it
is released from the
“catch”. It should swing
freely, and open/close
easily.
If further adjustment to
the door alignment is
required, loosen the
fastening bolts(Figure 20)
and adjust the door within
its ”frame” by moving the
outer case slightly - left to
right - until the correct
door operation is achieved.
Refasten all bolts.
Remove the gas control
knob from the extension
rod.
Take the Top Plate, open
the hinged gas control
access panel, and locate the
top plate onto the two
Fig. 20 Arched lintel to heater
attachment
Side Panels and
Arched Lintel,
taking care to insert
the control rod
through the guide
hole in the gas
control well (Figure
22). Refit the
control knob over
the control valve
extension rod. Push
firmly on.
Control Knob Adjustment
Due to
variations in
casting
dimensions the
height of the
shaft linkage
between the gas
control valve
and the control
knob can vary.
If the shaft is
too long, it
could prevent
the cast iron
Fig. 22A Control rod location
knob access door
from closing
properly. If the shaft is too short, it could prevent the pilot from
lighting because the gas valve is not depressing fully.
If the shaft protrudes less than 7/8”, first turn the control knob to
a position between the High and Medium setting. This will give
access to the Phillips head coupling screw through the hole found
at the rear of the heater in the mounting bracket which holds the
gas valve (see figure 22B). Adjust the coupling until 7/8” of shaft
protrudes through the hole in the top of the cast iron case.
Tighten the
screw.
If the shaft
protrudes
more than
7/8” at its
lowest
Fig 22B Control rod fastening
position ,
Tighten the
coupling screw at the lowest shaft position. Make a note of how
much the shaft protrudes in excess of 7/8”. Remove the cast iron
case top and lift the rest of the cast iron case away from the
heater. Screw out the leveling feet on the cast iron sides by the
amount of excess shaft protrusion. (This will raise the cast iron
case top so that the shaft only protrudes by 7/8”). Replace the cast
iron case and top.
IMPORTANT: Tighten the screw firmly against the flat
face of the “D” on the control knob spindle

MAKE FINAL CHECKS AND INSTRUCT OWNER
Make sure that the logs have not been dislodged when fitting the
case.
Fit the Caution & Direction label to the right hand side of the
case in the position shown in Figure 23.
Recheck the operation of
the fire on all control
positions.
Instruct the owner how
to correctly operate the
heater and especially
point out the following:The heater has a pilot. To
light the pilot, the control
knob must be depressed
and turned to the
position.
The pilot flame can be
viewed to check that it is
alight. Show the owner
where to view the pilot.
Point out the illustration
showing how to view the

Explain the full lighting
Fig. 23 Caution label position
and control position
sequence and how to
turn off. It must be explained that the gas control access panel
must be kept open while the heater is in operation. Advise that the
fire can be lit with a long match or taper if necessary.
Advise that the window will require cleaning periodically both
outside and inside as described in the instructions. Explain how to
remove and replace the window unit and logs for cleaning etc.
Stress that cleaning and opening of the door should only be
carried out when the heater is cold. Advise that the heater may
give off a slight odor while new. This is quite normal and will
disappear after a short period of use.
Advise that the bright metal firebox interior will color with use
and that this is quite normal. Emphasize that if the glass panel is
broken or damaged, the heater should be turned off and not used
until the window unit is refitted with an authorized replacement.

14. OPERATING PROCEDURE
Full lighting instructions are given on the next pages.
For your safety this heater is fitted with a Flame Supervision
Device which will shut off the gas supply if for any reason the
pilot flames go out. This device incorporates a fixed probe which
senses heat from the pilot flame. If the probe is cool the device will
prevent any gas flow unless the control knob is held down. When
first turned on, the decorative flames will appear predominantly
blue. After approximately 15 minutes these flames will turn
yellow.
After approximately 3 hours use at the high control setting the
fuel pieces will show areas of charcoal gray color as would real
burning logs.

In the unlikely event of failure of the ignition spark, the heater
can be lit by a long burning match as follows:
Open the cast door fully to gain access to the heater. Light the
match and insert through the opening in the black bar near the
bottom right corner of the window. Insert the match so that
about 1” is inside the black bar (see figure 24).
Open the hinged gas control access panel.
Depress the control knob and turn to the
position. Keep it
depressed while lighting the pilot and for a few seconds afterwards.
The pilot flame can be seen by looking through the gap at the
front right corner of the logs (see figure 25). When the pilot is
satisfactorily alight, close the door.

15. CLEANING
All cleaning should be carried out when the heater is cold. Normally,
the heater should only need dusting. Any stains on the glass can be
removed with a non abrasive cleaner.
Abrasive cleaners should never be used on the glass.
15.1 Cleaning the inside of the window:
Open the case door fully. Remove the window unit by detaching the
knurled screws at sides near the top. Lift the window unit assembly up
to clear the locations at the bottom - see fig 7. In installation section of
this manual.
Be careful not to disturb the logs when removing the window. If they
are disturbed, refit them as described in the log installation section of
this manual.
Clean the window carefully by wiping with a soft cloth using a
suitable non abrasive cleaner in accordance with the makers
instructions. Replace the window unit. Locate its bottom edge in the
support channels at the firebox sides. Refit the two knurled screws and
tighten. Replace the window surround.
17. CALLING FOR SERVICING
For owner
If you require any attention to your appliance, contact your supplier
quoting the model number. It is helpful if the appliance serial number
is also quoted. This will be found near the back of the case at the
bottom right side.
The servicing information on the following pages is for use
