INTRODUCTION
Congratulations on choosing an Brigantia fireplace!
The 24-DVRS25NB(N)-2 is one of the most advanced direct vent fireplace heaters available. It
is solidly designed using the latest technology and manufactured to the highest quality. It is our
aim to provide you with an appliance for many trouble-free years of reliable service.
The following are just some of the many features of your new gas fireplace:
CPI vs IPI:
Continuous Pilot on Demand Ignition (CPI): In this mode the pilot runs continuously even when the
main burner is off. The Continuous Pilot on Demand Ignition operates on a seven day cycle. If the main
burner is not turned on for seven continuous days, the pilot will turn itself off. When the main burner is lit
again the cycle repeats. The pilot will remain lit for seven days, even after the main burner is turned off.
If the main burner is lit during a seven day timing cycle, the seven day timer will reset.
Intermittent Pilot Ignition (IPI): A fuel saving mode in which the pilot is only used when the main
burner is on.
This appliance is shipped in IPI mode. IPI mode is often the preferred method, however, there are some situations
where it may be preferable to switch the fireplace into CPI mode. For example, in colder climates the glass door or
the front of the fireplace could become very cold to the touch. Dynamic Start Advantage will solve most problems
experienced by older IPI operated fireplaces.

VENTING
Clearance to combustibles
The following clearances must be maintained around the vent pipe:
Vertical runs: 1”
Horizontal runs: 2” on top, 1” sides and bottom
IMPORTANT: This appliance venting system is a sealed system (DV), which means that all combus-
tion air is supplied from outdoors and the combustion products are exhausted to the outdoors.
Note: Only venting systems listed in this manual may be used.
Planning your vent installation
This type of direct vent system may terminate in one of two ways: vertical termination using a vent cap,
or horizontally using a wall termination. There are limitations to the vertical and/or horizontal length.
Note: As this system is a sealed system,
The female section of the pipe/fitting has four indentations evenly spaced around the pipe. These indentations are
designed to slide over the male section of the pipe and fully lock by a clockwise quarter turn.
Vent Restrictors
Due to the extra flow produced by tall venting con-
figurations the vent restrictors must be adjusted to
maintain performance. The vent restrictor is de-
signed into the appliance firebox.
When required, adjust the restrictor inside the unit
firebox. Release the screws and adjust the restrictor
position according to the venting charts
LISTED VENTING SYSTEMS
The listed chimney vent systems uses a twist lock connection. Assemble the vent system using the de-
sired combination of sections and elbows for your installation. Make sure you fully insert and twist the
mating sections all the way to make a solid connection.

Installation Instructions Cont.
Horizontal Wall Vent Terminations
The position of the horizontal vent termination
must be positioned in such a way as to meet all
local building codes.
Attach the correct length of vertical section pipe
and an elbow fitting to the stove.
Mark the center line of the pipe facing the wall
(allowing for a 1/4” rise per foot of horizontal,
example 10ft of horizontal would require a rise
of 2.5”).
NOTE: ALLOWING THE VENT PIPE TO SLOP
DOWN TOWARDS THE VENT TERMINATION
COULD CAUSE POOR COMBUSTION AND/
OR HIGH TEMPERTURES THAT MAY PRE-
SENT A FIRE HAZARD.
Mark a 10” x 10” square around the center mark
(inside dimensions).
Cut and frame the exterior wall to accept the
Wall Thimble. Install the Wall Thimble shield
using wood screws. If the wall being penetrated
is constructed of non-combustible material con-
crete or block wall a 7” hole sufficient for the
vent pipe is acceptable.
Venting terminals must not be recessed
into wall or siding

When the termination is to be attached to vinyl siding
apply a bead of non-hardening mastic around the
outside edge to form a seal between the standoff
and the terminal. Attach the terminal to the exterior
wall using four wood screws through the holes in the
corner of the vent terminal.
Complete the terminal installation and apply a bead
of mastic around the outer edge of the vinyl standoff.
With the termination installed you can now connect
the completed vent assembly by sliding the unit back
towards the wall and carefully inserting the pipe into
the terminal.
Slide the pipe into the vent, making sure that at least
1¼” overlap between the pipe and the terminal.
To achieve the minimum vertical rise, a 14” or 36”
snorkel termination may be used. Do not install
where snorkel may be blocked by snow or sub-
merged in water. Ensure adequate space and
drainage.
Basement Installations
FOR PROPER VENTING
When planning your installation, it will be neces-
sary to select the proper length of vent pipe in-
stallations. For vertical installations, determine
the length of vent pipe required by measuring the
distance from the appliance flue outlet to the ceil-
ing, the ceiling thickness, the vertical rise in the
attic or second story, and allow for sufficient vent
height above the roof line. For two-story applica-
tions, fire-stops are required at each floor level. If
an offset is needed in the attic, additional pipe
and elbows will be required. Venting terminals
shall not be recessed into a wall or siding.

24-DVRS25NB(N)-2 15
Vertical Cap Installations
Installation Instructions Cont.
Always maintain a 1” clearance around the vent pipe
(vertical) and on horizontal venting 2” clearance on the
top of the vent, when passing through ceilings, walls,
roofs, enclosures, attic rafters or any combustible sur-
faces.
DO NOT PACK AIR SPACES WITH INSULATION.
Refer to the vent chart on page 15 for maximum allow-
able vertical and horizontal allowable installations.
When planning your installation, determine if ceiling
joists, roof rafters or other framing will obstruct the vent
system. You may have to use 45° elbows to navigate
around any obstacles. When passing through a flat
ceiling, install a Box/Wall thimble. Cut a 10” square
hole and frame as shown in the diagram opposite.
Ensure all pipe sections are fully twist locked.
NOTE: ALWAYS CHECK YOUR LOCAL
CODES BEFORE INSTALLING VENTING.
CLEARANCES, ETC, MAY VARY FROM
STATE TO STATE(PROVINCE TO PROVINCE).

INSTALLATION NOTE

24-DVRS25NB(N)-2 19
Before connecting the appliance to the gas supply line, double check that the appliance you
have purchased is designed for the gas type you are using. The gas type markings are located
on the certification label and also on the appliance’s gas valve.
Adequate clearance for proper installation and checking of the gas connections must be
provided. All gas connections must be checked for gas leaks.
GAS CONNECTIONS
Have your gas supplier or a qualified gas fitter run a gas supply line into the fireplace. The line
must be properly sized and fitted according to the installation codes. Immediately upstream of the
supply connection, the fitter shall provide an accessible manual shut-off valve. When connecting
the supply line to the gas valve, the installer shall brace the gas valve to ensure that the gas valve
is not moved from its bracket. If the valve is not braced when the supply line is connected, the
valve may be moved and cause a “break” in the main burner supply line. Such damage is not
covered by the manufacturer’s warranty.
CAUTION: The appliance and its individual shutoff valve must be disconnected from the gas
supply piping system during any pressure-testing of that system at test pressures in excess of 1/2
psig (3.5 kPa). The appliance must be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure-testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig (3.5 kPa). Failure to do so will damage the
appliance’s gas valve. Such damage is not covered by the manufacturer’s warranty.
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 5.0” W.C. (1.2 kPa) and a maximum of
14.0” W.C. (3.5 kPa). The orifice is a #43 DMS (2.26 mm) drill size.

The inlet supply or line pressure must be a minimum of 12.0” W.C. (2.98 kPa) and a maximum of
14.0” W.C. (3.5 kPa). The orifice is a #54 DMS (1.397 mm) drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 25,000 BTU/hr (9.1 kW)
4500 ft. (1372 M) and above. 25,000 BTU/hr (9.1 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.
NOTE: THE INPUT RATING SHOULD ALWAYS BE CHECKED WHEN FIRST RUNNING THIS
APPLIANCE. To do this, reduce the background flow rate, time the meter, light the fireplace and
take another reading after 15 minutes of operation. Check with your gas supplier for the gas BTU
content at your elevation. Input is the rate of flow multiplied by the heating value of the gas (cubic
feet/hour x BTU per cubic feet). Adjust the manifold pressure so that the unit does not operate
above the rated input.

1. Remove the surround.
2. The pressure test taps are located on the valve. The taps are located in the gas valve front face.
The inlet is marked ‘IN’ and the outlet is marked ‘OUT’. See Fig.1.
3. Loosen the set screw inside the tap with a screwdriver.
4. Connect a 1/4” (6 mm) rubber tube to the tap post and a manometer.
5. Verify that the readings obtained are within specs (as shown on the appliance rating plate)
6. Be sure to tighten the set screw inside the tap after you have finished taking pressure readings.
7. Check for leaks.
