This replace must be installed by a qualied
(certied or licensed) service person. It has
a sealed gas combustion chamber that uses
a coaxial pipe (pipe within a pipe and having
the same center) venting system. It brings in
fresh air for combustion through the outer pipe
and combustion gases are exhausted through
the inner pipe. If the glass door assembly and
venting pipe are not properly seated, con-
nected and sealed, carbon monoxide leakage
(spillage) can occur.

propane/LP gas are odorless. An odor-making
agent is added to the gas. The odor helps you
detect a gas leak. However, the odor added to
the gas can fade. Gas may be present even
though no odor exists.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this replace.

PRODUCT IDENTIFICATION
Figure 1 - Direct-Vent Fireplace with Millivolt Ignition
PRODUCT FEATURES
These are a few facts that can help you under-
stand and enjoy your direct-vent replace:
• The venting system may be routed to the
outside of your home in several ways. It
may vent through the roof (vertical) or it
may vent to an outside/exterior wall (hori-
zontal). The vent pipe installation is very
important to allow for proper operation.
You must follow the venting instructions
very carefully for either vertical or horizontal
applications.
• This replace may be installed in any room
of your house provided all local codes and
these installation instructions are followed.
• This replace requires a wall switch, hand-
held remote or wall thermostat (millivolt) for
operation (see Accessories, page 42).
• This replace does not require electricity
to operate.
• Only the blower requires electricity if in-
stalled and if you plan to install the blower at
a later date, do not forget to wire the outlet at
the bottom of the replace when framing.
• A piezo ignitor and ceramic electrode cre-
ate spark to ignite the pilot light. It does not
require any matches, batteries or any other
sources of ignition to light the pilot.
• Each time you turn on your replace, you
may notice some amount of condensation
on the inside of the replace glass. This
is normal and will disappear after 10-20
minutes of operation.
• Your direct-vent gas fireplace system
(replace and venting) is a balanced and
sealed gas operating unit. It requires ap-
proximately 10-20 minutes of operating
time before the ame pattern stabilizes.
• Fireplaces with the sufx of -HA have been
designed to operate at altitudes of 4000
feet and above.

LOCATION AND SpACE
REqUIREMENTS
Determine the safest and most efcient loca-
tion for your Ironhaus direct-vent replace.
Make sure that rafters and wall studs are not
in the way of the venting system. Choose a
location where the heat output is not affected
by drafts, air conditioning ducts, windows or
doors. Figure 2 shows some common loca-
tions. Be aware of all restrictions and precau-
tions before deciding the exact location for
your replace and termination cap.
When deciding the location of your replace,
follow these rules:
• Do not connect this replace venting to a
chimney ue serving a separate solid-fuel
burning replace or appliance.
• Due to high temperatures, do not locate this
replace in high trafc areas, windy or drafty
areas or near furniture or draperies.
• Proper clearances must be maintained.
• If your replace is to be installed directly on
carpeting, vinyl tile or any combustible mate-
rial other than wood, it must be installed on a
metal or wood panel extending the full width
and depth of the replace. See Figure 3,
• Your replace is designed to be used in
zero clearance installations. Wall or framing
material can be placed directly against any
exterior surface on the back, sides or top of
your replace, except where standoff spacers
PRE-INSTALLATION PREPARATION
are integrally attached. If standoff spacers
are attached to your replace, these spacers
can be placed directly against wall or framing
material. See framing details on page 7.
• If you plan on installing a television or enter-
tainment center recessed above your re-
place, it is recommended that you maintain a
minimum 18" above top of louver opening.
• When locating termination cap, it is impor-
tant to observe the minimum clearances
shown in Figure 7, page 8.
• If recessing into a wall, you can avoid extra
framing by positioning your replace against
an already existing framing member.
• Do not recess termination cap into a wall
or siding.
• You may paint the termination cap with
450º F (232º C) heat-resistant paint to
coordinate with the exterior nish.
• There must not be any obstruction such
as bushes, garden sheds, fences, decks
or utility buildings within 24" from the front
of the termination cap.
• Do not locate termination cap where exces-
sive snow or ice build up may occur. Be sure
to clear vent termination area after snow falls
to prevent accidental blockage of venting
system. When using snow blowers, do not
direct snow towards vent termination area.
• For horizontal installations above 2,000
feet, it is recommended that a 12" extension
pipe be added before starter elbow and a
round horizontal termination be used (see
High Altitude Installation, page 17).
CLEARANCES
Minimum clearances to combustibles for the
replace are as follows:
*Back and sides 0"/cm
Perpendicular walls 6" (15 cm)
Floor 0"/cm
Ceiling to louver opening 42" (107 cm)
Front 36" (91 cm)
Top of Standoffs 0"/cm
Vent (See venting instructions
for specic venting clear-
ances.)
Combustible material with a maximum thick-
ness of 5/8" may be ush with the top front
of replace.
* For back and sides of replace, do not pack
with insulation or other materials. 0" clear-
ance to combustible materials are for framing
purpose only.

These models are tested and approved for
use with DESAHeating, LLC (direct-vent) pipe
components and terminations.
The venting system must terminate on the out-
side of the structure and can not be attached
to a chimney or ue system serving a separate
solid fuel or gas burning appliance.A direct-vent
appliance must have its own venting system.
DO NOT common vent this appliance.
These models are approved to be vented
either horizontally through an outside wall or
vertically through a roof or chase enclosure
using the following guidelines:
• When venting system terminates horizon-
tally on an outside wall, you may install
a standoff if the termination cap is to be
installed directly on a combustible nish
such as vinyl, wood, stucco, etc.
• Never run the vent downward as this may
cause excessive temperatures which could
cause a re.
• Vent pipe air space clearances to com-
bustibles are 1" on all sides except on the
horizontal sections, which requires 2" clear-
ance from the top of the pipe. Where the
termination cap penetrates a combustible
wall, 1" air space clearance is required.
• Snorkel terminations are required when
minimum clearance to grade cannot be
met (see Figure 16 on page 13).
• Have replace and selected vent compo-
nents on hand to help determine the exact
measurements when elbowing or offsetting.
Always use wall restops when penetrating
walls and restops when penetrating ceil-
ings or attic spaces.
• If using a venting conguration of only
horizontal venting with no vertical run, a
1/4" rise for every 12" of run toward the
termination is required.
• For installation of replace at elevations of
4000 feet or greater, pay special attention
to venting requirement recommendations.

INSTALLATION pLANNING
There are two basic types of direct-vent
installation:
• Horizontal Termination
• Vertical Termination
Horizontal Termination Installation
IMPORTANT: Horizontal square terminations
require only inner portion of wall restop. Hori-
zontal installations using round termination
require exterior portion of wall restop (see
Figure 14, page 12).
1. Set replace in its desired location and
determine route your horizontal venting
will take. Do not secure replace until all
venting has been installed. Some instal-
lations require sliding replace in and out
of position to make nal venting connec-
tions. Figures 14 through 18 on pages 12
through 14 show different congurations
for venting with horizontal termination that
will help you decide which application best
suits your installation. Check to see if wall
studs or roof rafters are in the path of your
desired venting route. If they are, you may
want to adjust location of replace.
2. Direct vent pipe sections and components
are designed with special twist-lock con-
nections.
Twist-Lock procedure: Female ends of
pipes have locking lugs (indentations).
These lugs will slide straight into match-
ing slots on male ends of adjacent pipes.
Push pipe sections together and twist
one section clockwise approximately
one-quarter turn until the sections are fully
locked (see Figure 8).
Note: Horizontal runs of vent must be sup-
ported every three feet. Use wall straps
for this purpose.
3. Use a 45° elbow to connect venting sys-
tem to replace ue collar. The elbow is
designed to be twist-locked onto ue collar
as described in step 2. IMPORTANT: Do
not attempt to alter conguration of elbow
by cutting, twisting, bending, etc.
4. Assemble desired combination of pipe
and elbows to replace ue collar. If there
are long portions of venting run, pre-
assembled pipe sections may be installed
as subassemblies for convenience.

5. Carefully determine location where vent
pipe assembly will penetrate outside
wall. Center of hole should line up with
center line of horizontal vent pipe. Mark
wall for a 11 1/2" x 11 1/2" square hole.
Cut and frame square hole in exterior
wall where vent will be terminated. If wall
being penetrated is constructed of non-
combustible material, such as masonry
block or concrete, a 8 1/2" hole with zero
clearance is acceptable (see Figure 9).
