Safety and Your Fireplace
Please Follow These Important
Child Safety Precautions and
Recommendations,
• Parts of your Valor Fireplace become
extremely hot while in operation.
• The glass viewing window
temperature can exceed 500 F
at full capacity.
Momentary contact
with a hot glass
surface can cause
a severe burn,
even if the fireplace
is operating at reduced heating
capacity.
• The glass window will remain hot
for an extended period of time after
the fireplace has been turned off.
Ensure that children are prevented
from touching the fireplace during the
cool down period.
• Toddlers and Young Children
must be closely supervised at all
times when they are in the same
room as the operating fireplace. They
lack full awareness of danger and
rely on your protection. Toddlers, in
particular, do not have the motor skills
and response reflexes to withdraw in
the event of accidental contact with a
hot surface.
• A physical barrier is strongly
recommended if there are young
children, or at-risk individuals in the
house. Install an approved after-market
safety gate to keep toddlers, young
children and other at-risk individuals a
safe distance from the fireplace.
• Keep the remote control handset
out of reach of children at all
times. A wall mount storage holster
is provided with your remote control
handset.
• Ensure that the fireplace, including
the pilot light, is completely turned
off when children are present and
close supervision and safety barriers
are not available—see page 8 of
Owner’s Information section.
• If the fireplace is not going to be used
for the summer or any extended
period of time, remove the batteries
from the remote control handset
and receiver. It is recommended that
batteries are replaced annually in any
event—see page 7.
Please Read and Carefully Follow all Safety Warnings and
Operating Instructions Contained in Your Owners Manual
(Replacement Manuals are available by contacting our service department at
1-800-468-2567 or visit www.valorfireplaces.com).

Operating Your Fireplace for the First Time
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. We
recommend opening a window to vent the room. After
a few hours use, the vapors will have disappeared and
the flames will be at their normal height.
Flame Supervision Device
For your safety, this appliance is fitted with a flame
supervision device which will shut-off the gas supply
if, for any reason, the pilot flame goes out. This device
incorporates a fixed probe, which senses the heat
from the pilot flame. If the probe is cool, the device will
prevent any gas flow unless manually lighting the pilot.
See full lighting instructions on page 12 of this manual.
Owner’s Information
Performance of LPG appliances may be affected by
the quality of commercial gas supplied in your area.
Do not put
furniture or other objects
in this space in front of

This manual and particularly the preceeding
and following pages contain very important
information regarding the safe operation of your
fireplace as well as maintenance instructions.

and pay special attention to the SAFETY
WARNINGS.
A heating gas appliance does require safe handling
and for this reason, we very strongly recommend that
no children be allowed to touch the fireplace and its
controls at all times. Do install a screen or barrier
in front of the fireplace to protect your children
against severe burns.

- Some parts of your fireplace are EXTREMELY
HOT, particularly the GLASS window.
- DO NOT LET CHILDREN touch the glass or any
parts of your fireplace even after it is turned off

INFORMATION

Owner’s Information
Cleaning
Important - Glass cleaning - Mineral deposits
One of the by-products of the combustion process in
a gas appliance is a mineral which can show up as a
white film on the ceramic glass of the viewing door.
The composition of the deposit varies widely from
various locations and also from time to time in the
same location. It seems this is associated with the
varying sulfur content of the gas. You may have the
problem for a time and then not see it for many months
when it will reappear in your area.
We have discussed this problem with ceramic glass
manufacturers and they cannot give us a definitive
answer to this problem. Dealers have tried various
cleaning products with varying results. The following
recommendations will not guarantee results in your
particular case.
NOTE: This is a problem beyond Miles Industries’
control and is not covered under warranty.
• Clean the glass regularly as soon as you notice
the buildup (white film). If the film is left for a longer
period of time, it will bake on. It is then much harder,
if not impossible, to remove.
• NEVER use an abrasive cleaner on the ceramic
glass. Any abrasion of the surface has the
immediate effect of compromising the strength of the
glass. An emulsion type cleaner is recommended.
• Use a soft damp cloth to apply the cleaner. Dry the
glass with a soft, dry, preferably cotton cloth. Most
paper towels and synthetic materials are abrasive to
ceramic glass and should be avoided.
• Our dealers have had good results from the
products listed below. We cannot, however,
guarantee the results of these products.

CREME by ELCO, WHITE OFF by RUTLAND, TURTLE WAX
Do not clean the glass while it is hot. Always
securely replace the window before lighting. If broken,
the glass pane may only be replaced as a complete
window unit as supplied by the manufacturer.
To remove the window for cleaning:
1. Turn each bolt a quarter turn to disengage the bolt pin.
2. Gently pull
the bottom of
the window
outward and
unhook it from
the firebox’s
opening frame.
3. Set the window
aside in a safe
place to avoid
damage.
To refit the window:
1. Hook its top part to the firebox’s opening frame.
Make sure that the wider part of the window
frame is at the bottom.
2. While you hold the
window, push in
and turn the two top
spring-loaded bolts
a quarter turn to
engage their pin.
3. Push in the bottom of
the window against
the firebox and
fasten the two bottom
spring-loaded bolts a
quarter turn.
4. If the Hot Glass Warning plate has been removed
from the front lower corner of the window,
reinstall it by sliding it between the glass and
the frame as indicated.
WARNING
!
DO NOT TOUCH THE GLASS WHILE IT IS HOT!
Let the fireplace cool first before touching it.

Vent Location
The vent terminal must be located through the roof. This gravity
vent appliance is designed to opreate when an undistrubed
airflow hits the outside vent terminal from any direction.
Check local codes for allowable vertical vent termination.
Vent Materials
Use a 3” diameter aluminum flex liner approved for gas
venting when installed as an insert (existing chimney). Use a
4” diameter type “B” vent when installed with a 770ZCK Zero
Clearance Kit (see separate instructions packaged with the kit
for details).
Venting Notes
Where possible, avoid joining flex pipe. If joints are required,
use a approved connector and seal joints with RTV high temp
sealant.
Horizontal offsets are permissible to allow for routing around
masonry projections. Avoid bending flex pipe over a 45 degrees
radius where possible.

Installation Planning
Installer—READ THIS FIRST
1. YOU NEED TO KNOW FROM THE
HOMEOWNER what accessories (surround,
door, etc.) will be installed with this fireplace;
2. Unpack the appliance.
3. Check that you have everything.
4. Clean cavity, chimney, ash dumps, clean-outs.
5. Install venting pipe.
6. Attach conversion plate to existing fireplace.
7. Fit appliance into cavity.
8. Connect and test gas supply.
Existing Fireplace Preparation
A few points must be considered before inserting the
738BX into an existing fireplace cavity. Generally, no
modifications are allowed to the existing fireplace that
will compromise the integrity of the existing fireplace.
Components that are bolted or screwed on such as
dampers or baffles may be removed to accommodate
the installation of the 738BX engine. Cutting away
any sheet metal parts of the existing fireplace
to accommodate the installation of the 738BX is
prohibited. Check with local authorities if in doubt.
Clean Fireplace and Chimney
Have the chimney swept and the fireplace cavity
including ash dumps and clean-outs cleaned before
installing the 738BX heater and vent liners. Any
creosote or soot residue remaining in the fireplace
cavity chimney or clean-out may cause odors or
stains once the 738BX insert is installed. Consult with
chimney sweep for information on how best to clean.
Existing Dampers
Factory-built, zero-clearance fireplaces will require the
damper to be removed in order to install the vent liners.
These dampers are usually bolted into place. Dampers
in masonry fireplaces must be fixed open and may
remain in place.
9. Install the remote control system.
10. Install bricks and logs.
11. Refit window.
12. Verify operation and adjust aeration settings.
13. Install the remote control handset wall holder.
14. Instruct the homeowner on the operation and
maintenance of the fireplace.
15. Install the surround trim and front.
16. Install the fret if required.
Ash Retaining Curbs
Some fireplaces (particularly factory-built) have a
raised curb at the front edge to retain ashes. Check the
dimensions carefully to ensure the 738BX engine will fit
behind any raised curb (some curbs may be removed
separately from the refractory base).
Gas Line Routing
Plan the routing of the gas line before proceeding.
Use the existing hole for the gas line in factory-built
fireplaces. If the fireplace has no access hole, carefully
drill an access hole of 1.5 inch (38 mm) or less through
the lower sides or bottom of the firebox. The access hole
must be plugged with non-combustible insulation after
the gas supply line has been installed. See Dimensions
section for detailed location of gas inlet. Also, take
into consideration whether or not a shut-off valve will
interfere when planning routing of the gas line.
Only qualified licensed or trained personnel
should install this appliance.

avoid damage.
4. Verify that you have all the components required
for the installation, including:
-brick panels & logs;
- surround/doors/fret;
- venting components and accessories.
Appliance Preparation
Existing Fireplace Preparation
Existing Glass Doors and Wire Screens
Existing glass doors must be permanently removed
prior to installing the 738BX insert.
Combustible Mantels
Combustible mantel clearances must conform to those
required for the original solid-fuel fireplace into which
the 738BX is being installed.
Window Removal
The window is held in place by four spring-loaded bolts,
two at the top and two at the bottom.
1. To remove the window, turn each bolt a quarter turn
to disengage the bolt pin.
2. Gently pull the bottom of the window outward and
unhook it from the firebox’s opening frame.
3. Set the window aside in a safe place to avoid
damage.
Attach Warning Conversion Plate to Existing
Fireplace (label supplied loose with 738BX
heater)
Attach the “This fireplace has been converted...”
label to the existing fireplace using screws or other
mechanical means and store any removed parts in
back of the existing fireplace for future use.

Venting Installation
IMPORTANT: This appliance’s venting system requires room air to be used
in the combustion process.
1. Rough-in one 3” diameter vent liner into the existing chimney
system from the roof. Be careful not to tear or damage the liner
in the process. Leave plenty of liner at the bottom to facilitate the
connection of the liner to the vent slider. It is best to leave the top
termination until later.
2. a) Large cavity opening
Slide the appliance into the cavity.
b) Smaller cavity opening
Release the two screws retaining the vent slider to the front of the
firebox.
Remove the slider from the firebox by sliding it towards the back of
the firebox.
3. Secure the liner to the collar on the vent slider using 4 tapping
screws.
If the vent slider was removed from the firebox, slide the firebox
onto the vent slider in the cavity taking care not to damage the liner.
Make sure that the vent slider is pulled all the way forward.
Secure the vent slider to the front of the firebox with two screws
removed earlier.
4. From the roof, pull the liner and fit the flashing.
5. Fit the terminal cap. Secure with screws.
6. Seal the terminal and flashing from water penetration as required.
