California Health & Safety Code Sec. 25249.6
This appliance may be installed in an aftermarket
permanently located, manufactured home or mobile
home, where not prohibited by local codes.
This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is
not convertible for use with other gases, unless a
certified kit is used.
The DVRTSB has been approved for mobile home
installations.
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
Remove any plastic from trim parts before turning the
fireplace ON.
It is normal for fireplaces fabricated of steel to give off
some expansion and/or contraction noises during the
start up or cool down cycle. Similar noises are found
with your furnace heat exchanger or car engine.
It is not unusual for a gas fireplace to give off some
odor the first time it is burned. This is due to the
curing of the paint and any undetected oil from the
manufacturing process.
Please ensure that your room is well ventilated
- open all windows during burn in period.
It is recommended that you burn your fireplace for
at least ten (10) hours the first time you use it. If
the optional fan kit has been installed, place the fan
switch in the “OFF” position during this time.

Hearth
A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305mm) or more from
the front of the fireplace.
Cold climate installation recommendation:
When installing this unit against a noninsulated exterior wall or chase, it is
mandatory that the outer walls be insulated
to conform to applicable insulation codes.
Framing and Finishing
1. Choose the unit location.
2. Place the unit into position and secure it to the floor
with 1¹⁄₂” (38 mm) screws, or nails. The holes to
secure the unit to the floor are located just behind
the access door grille on the left and right side of the
unit.
3. Frame in the fireplace with a header across the top.
It is important to allow for the finished wall face when
setting the depth of the frame.
4. Drywall (sheetrock) or wood material may be placed
with a zero clearance to the top edges of the appli-
10003848
Page 7

ance when finishing walls above sides of the appli
ance with glass windows. Attach the wall finishing to
the constructed frame not the appliance.
5. On DVRTSB models, drywall, wood or wood molding
may be placed with zero clearance to the rear
wall of the unit, along the vertical edge formed
by the standoffs to intersection of the rear wall to the
side wall containing the small glass window. Attach
the wall finishing to the constructed frame, not the
appliance.
-
Final Finishing
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the appliance.
DO NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the edges
of the appliance.

Gas Line Installation
When purging the gas lines, the front glass
must be removed.
The gas pipeline can be brought in through the side and
back of the fireplace as well as the bottom. Knockouts
are provided on the bottom behind the valve to allow for
the gas pipe installation and testing of any gas connection. It is most convenient to bring the gas line in from
the right side of the valve as this allows fan installation
or removal without disconnecting the gas line.
The gas line connection can be made with properly
tinned 3/8” copper tubing, 3/8” rigid pipe or an approved
flex connector. Since some municipalities have additional local codes, it is always best to consult your local
authority and the CSA-B149.1 installation codes.
For USA installations consult the current National Fuel
Gas Code, ANSI Z223.1/NFPA 54.
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.

The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8” test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so the gas line can be easily disconnected for
burner or fan servicing. Refer to the gas specification
for pressure details and ratings.
The fireplace valve must not be subjected
to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or any other gas
appliance control from the gas line when
pressure testing.

General Information for Connecting Vent Pipes
To join the twist lock pipes together, simply align the
beads of the male end with the grooves of the female
end, twisting the pipe until the flange on the female
end contacts the external flange on the male end. It is
recommended that you secure the joints with three (3)
sheet metal screws, however this is not mandatory with
twist lock pipe.
NOTE: For ease of assembly, use a lubricant (Vaseline
or similar substance) on male end of twist lock pipe
prior to assembly.

How to Use the Vent Graph
The vent chart should be read in conjunction with the
following vent installation instructions to determine the
relationship of the vertical and horizontal dimensions of
the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph, (Fig. 15)
locate the point intersecting with slanted graph line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
3. Select the indicated dimension, and position the
fireplace in accordance with same.
Example A:
If the vertical dimension from the floor of the
fireplace is 11’ (3.4 m) the horizontal run to the face
of the outer wall must not exceed 14’ (4.3 m).
Example B:
If the vertical dimension from the floor of the unit is
7’ (2.14 m), the horizontal run to the face of the outer
wall must not exceed 8¹⁄₂’ (2.6 m).
Rear Wall Vent Applications
When installed as a rear vent unit this appliance may
be vented directly to a termination located on the rear
wall behind the appliance.
• Specific rear vent starter kits must be used in these
applications (see ‘Venting Components’). The
appliance has been approved for installation flat
against a rear wall. (Fig. 16)
• The maximum horizontal distance between the rear
of the appliance and the outside face of the rear wall
is 20” (508mm). (Fig. 16)
• The minimum clearances between any combustible
material and the vent pipe sections are:
Top ..................................................... 2” (51 mm)
Sides .................................................. 1” (25 mm)
Bottom ................................................ 1” (25 mm)
When the vent termination is installed in an accessible
location, a Screen Guard Kit, item #7V1B60, should be
installed. (Accessible means the termination is likely to
be touched)

STEP 3
Measure the horizontal length requirement for the venting including a 2” (51 mm) overlap, i.e. from the elbow
to the outside wall face plus 2” (51 mm) (or the distance
required if installing a second 90° elbow. (Fig. 17)
STEP 4
Install the 4” (102 mm) vent to the appliance collar and
secure with three (3) sheetmetal screws. Install the 7”
(175 mm) vent pipe to the appliance collar and secure
with three (3) sheet metal screws. It is not necessary to
seal this connection.
It is critical that there is no downward
slope away from the appliance when connecting the vent or elbow.
STEP 5
Guide the vent through the vent hole as you place the
appliance in its installed position. Guide the 4” (102mm)
and 7” (175 mm) collars of the vent termination into the
outer ends of the venting. Do not force the termination.
If the vent pipes do not align with the temination remove
and realign the venting at the appliance flue collars.
Attach the termination to the wall as outlined in the
instruction sheet supplied with the termination.
Vertical Sidewall Applications
Since it is very important the venting system maintain
its balance between the combustion air intake and the
flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.
The vent graph showing the relationship between vertical and horizontal side wall venting will help to determine the various dimensions allowable.
Minimum clearance between vent pipes
and combustible materials is one 1”
(25mm) on top, bottom and sides unless
otherwise noted.
When the vent termination exits through foundations
less than 20” (508 mm) below siding outcrop, the vent
pipe must flush up with the siding.
It is always best to locate the fireplace in such a way
that minimizes the number of offsets and horizontal
vent length of vent pipe from the flue collar of the fire
place to the face of the outer wall.
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
When installing the appliance as a rear
vent unit the 90° Transition Elbow attached
directly to the rear of the unit is not included in the following criteria and calculations, and unless specifically mentioned
should be ignored when calculating venting layouts.

• The maximum number of 90° elbows per side wall
installation is three (3).
• If a 90° elbow is fitted directly on top of the fireplace
flange, the maximum horizontal vent run before the
termination or a vertical rise is 36” (914 mm).
FP1381
Fig. 20 Maximum horizontal vent run.
• If a 90° elbow is used in the horizontal vent run
(level height maintained) the maximum horizontal
vent length is reduced by 36” (914 mm). (Fig. 21)
This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. (Fig. 21)
Example: According to the chart the maximum horizontal vent length in a system with a 7.5’ vertical rise is
20’ (6 m) and if a 90° is required in the horizontal vent it
must be reduced to 17’ (5.2 m).
Dimension A plus B must not be greater than 17’

Vertical Sidewall Installation
STEP 1
Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 23) For
combustible walls first frame in opening. (Fig. 23)
Combustible Walls: Cut a 9³⁄₈”H x 9³⁄₈”W (240 x
240mm) hole through the exterior wall and frame as
shown in Figure 23.
Noncombustible Walls (Fig. 23): Hole opening must
be 7¹⁄₂” (190 mm) in diameter.
FP1382
Fig. 21 Maximum vent run with elbows.
• The maximum number of 45° elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced by
18” (45cm). This does not apply if the 45° elbows are
installed in the vertical part of the vent system.
• The maximum number of elbow degrees in a system
is 270°. (Fig. 22)

Place fireplace into position. (Fig. 25) Measure the ver
tical height (X) required from the base of the flue collars
to the center of the wall opening.
STEP 5
Measure the horizontal length requirement including a
2” (51 mm) overlap, i.e. from the elbow to the outside
wall face plus 2” (51 mm) (or the distance required if
installing a second 90° elbow. (Fig. 26)
Always install horizontal venting on a level
plane.
STEP 6
Use appropriate length of pipe sections - telescopic or
fixed and install. The section which goes through the
wall is packaged with the starter kit, and can be cut to
suit if necessary.
Sealing vent pipe and firestop gaps with high temperature sealant will restrict cold air being drawn in
around fireplace.
Fig. 25 Vertical height requirements.
STEP 4
Apply a bead of silicone to the inner and outer flue
collars of the fireplace and using appropriate length of
pipe section(s) attach to fireplace with three (3) screws.
Follow with the installation of the inner and outer elbow,
again secure joints as described in “Connecting Vent
Pipes”.

(175mm) collars or the termination one inch away from
crimped end. Guide the vent terminations 4” and 7” collars into their respective vent pipes. Double check that
the vent pipes overlap the collars by 2” (50mm). Secure
the termination to the wall with screws provided and
caulk around the wall plate to weatherproof.
Support the horizontal pipes every 36” (914mm)
with metal pipe straps.
Check the fireplace to make sure that it is levelled

Below Grade Installation
When it is not possible to meet the required vent terminal clearances of 12” (305 mm) above grade level a
starter kit is recommended. It allows installation depth
of down to 7” (178 mm) below grade level. The 7”
(178mm) is measured from the center of the horizontal
vent pipe as it penetrates through the wall.
If venting system is installed below ground, we recommend a window well with adequate and proper drainage.
Ensure sidewall venting clearances are observed.
If installing a snorkel, a minimum 24” (610mm) vertical
rise is necessary. The maximum horizontal run with the
24” (610mm) vertical pipe is 36” (914mm). The measurement is taken from the collar of the fireplace (or transition elbow) to the face of the exterior wall. See Vent
Chart (see ‘How to use the Vent Graph’) for extended
horizontal runs if the vertical exceeds 24” (610mm).
1. Establish vent hole through the wall. (Fig. 23)
2. Remove soil to a depth of approximately 16”
(406mm) below base of snorkel. Install drain pipe.
Install window well (not supplied). Refill hole with 12”
(305mm) of coarse gravel leaving a clearance of approximately 4” (100mm) below snorkel. (Fig. 27)
3. Install vent system.
4. Ensure a watertight seal is made around the vent
pipe coming through the wall.
5. Apply high temperature sealant caulking (supplied)
around the 4” and 7” snorkel collars.
6. Slide the snorkel into the vent pipes and secure to
the wall.
7. Level the soil so as to maintain a 4” (100mm) clear
ance below snorkel. (Fig. 27)

Vertical Through-the-Roof Applications
This Gas Fireplace has been approved for:
• Vertical installations up to 40’ (12 m) in height. Up to
a 10’ (3 m) horizontal vent run can be installed
within the vent system using a maximum of two 90°
elbows. (Fig. 29 & 30)
• Up to two (2) 45° elbows may be used within the
horizontal run. For each 45° elbow used on the
horizontal level the maximum horizontal length must
be reduced by 18” (457 mm).
Example: Maximum horizontal length
0 x 45° elbows = 10’ (3 m)
1 x 45° elbows = 8.5’ (2.6 m)
2 x 45° elbows = 7’ (2.1 m)
• A minimum of an 8’ (2.4 m) vertical rise.
• A maximum of two (2) sets of 45° elbow offsets can
be used within these vertical installation. From 0 to
a maximum of 8’ of vent pipe can be used between
elbows. (Fig. 30)
• 7DVCS supports offsets. (Fig. 32) This application
will require that you first determine the roof pitch
and use the appropriate starter kit. (See Venting

Glass Cleaning
It is necessary to periodically clean glass. During startup condensation, which is normal, forms on the inside
of the glass. This condensation causes lint, dust and
other airborne particles to cling to glass surface.
Also initial paint curing may deposit a slight film on the
glass. It is therefore recommended glass be cleaned
two or three times with a non-ammonia based household cleaner and warm water (We recommend gas
fireplace glass cleaner) within the first few weeks of
operation.
After the initial cleaning process the glass should be
cleaned two or three times during each operating
season depending on the environment in the house.
Clean the glass after the first two weeks of
operation.
Ceramic Refractory Installation
The rear wall refractory panels are installed in the unit
prior to shipment.
1. Unpack the ceramic refractory panels from their
carton.
Handle the refractory material carefully, the
panels are fragile.
2. Place the front floor refractory panels on the base
of the fireplace. (Fig. 38)
3. Place both side panels in place along the side of
the base. (Fig. 38)
Installation of Logs
The logs can be identified by the number cast into
their underside.
The logs must be correctly placed in the order
described for the correct operation of the fireplace.
Refer to Figures 30 & 40 for log location and alignment.
1. Unpack the logs from the shipping carton. Handle
the logs carefully as they are fragile.
Handle and dispose of the plastic bags in a
safe manner. They are not toys and should
be kept away from infants.
2. Remove front glass/frame assembly.
3. Place the left rear (B105) and right rear (B106)
logs in place on the grate. The square hole in the
underside of the logs locates over the corner legs
of the grate. The inner ends of the log point to the
center of the burner.
4. Place the left front (B107) and right front (B108) logs
in place. Again the square holes fit over the corner
legs of the grate. The inner ends of these logs have
a recess in the underside which locates over knobs
on the top of the B105 and B106 logs to lock the
inner end in place.
5. Place the center front (B109) log in place. The notch
on the outer end of this log locates around the third
outer prong on the grate and the inner ends with a
round recess rest on lug on top of the left front log
(B107).
6. Place the center rear (B110) log in place. The square
hole in the underside of this log, locates over the

Maintenance
Burner and Burner Compartment
It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and replace the logs as per the instructions in this
manual.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
FK24/FK12 Fan Assembly
The fan unit requires periodic cleaning. At least once
per month in the operating season, open the lower
louvre panels and wipe or vacuum the area around the
fan to remove any build up of dust or lint.

Clean the brass trim pieces using a soft cloth lightly
dampened with lemon oil. Do not use water or
household cleaners on any brass components.
Contact your local representative to arrange an annual
service program.
Cleaning the Standing
Pilot Control System
The burner and control system consists of
• burner tube • gas orifice
• pilot assembly • thermopile
• millivolt gas valve
Most of these components may require only an occasional checkup and cleaning and some may require
adjustment. If repair is necessary, it should be per-
formed by a qualified technician.
To obtain proper operation, it is imperative that the pilot
and burner’s flame characteristics are steady, not lifting
or floating.
Typically, the top 3/8” or 1/2” of the thermopile should
be engulfed in the pilot flame. (Fig. 47)
To adjust pilot burner; (by qualified service technician)
1. Remove pilot adjustment cap.
2. Adjust pilot screw to provide properly sized flame.
3. Replace pilot adjustment cap.
The primary air shutter is set at factory and should only
be adjusted, if necessary, by a qualified service technician.
