SELECTING LOCATION
To determine the safest and most efficient location for your appliance, you must take into consideration the following guidelines:
1.The location must allow for proper clearances (see Clear-ances, page 6).
2.Consider a location where heat output would not be affected
by drafts, air conditioning ducts, windows, or doors.
3.A location that avoids the cutting of joists or roof rafters will
make installation easier. Figure 2 shows a plan view of a few
common locations.
Flush installations are recommended where living space is limited
or at a premium, and since the space required to enclose the
appliance would be located beyond an outside wall, this would also
reduce the cutting of joists, roof rafters, and such. Check local codes
for any restrictions.
Projected installations can extend any distance into the room. A
projection may be ideal for a new addition on an existing, finished wall.
Corner installations make use of space that may not normally be
used and provides a wider and more efficient range for radiant heat
transference.

VENTING INSTALLATION
A B-type venting system must be connected to the appliance for
venting to the outside of the building.
The following section is provided as a guide to a standard B-type
vent installation.
Standing codes requirements concerning B-type vent installations
may vary within your state, province or local codes jurisdiction.
Therefore, it is recommended that you check with your local
building codes for specific requirements or in absence of local
codes, follow Section 7.0 of the current National Fuel Gas Code
NFPA No. 54/ANSI Z223.1 and in Canada with CAN/CSA B149 for
Category I systems using double wall B-1 vent pipe .
This gas appliance must be vented to the outdoors only and may not
be terminated into an attic space or into a chimney flue servicing a
solid-fuel burning appliance.
This appliance may be vented through a manufactured chimney
system or a masonry chimney using a B-vent adapter or a chimney
liner system if all are listed, inspected and approved by local codes
and/or building authorities.
The examples shown in Figure 10 are typical of most B-vent
installations and codes practices.

Example 1:
Shows the minimum allowable system height and
lateral offset for a 60° degree or greater inclination. Code specifies
that offsets at 60° degrees or greater are considered horizontal and
must follow the 75% percent rule for lateral to total vertical system
height. Codes also allows only one offset in the total system when
at 60° degrees or greater. The total vertical height in this example
represents the minimum height of 8 feet and therefore the allowable
lateral is 6 feet when the 75% percent rule applies. If the lateral
length must exceed 75% then the system must be sized in accordance with the Category I venting tables.
Example 2:
Shows a multiple offset each at 45° degrees of
inclination. Multiple offsets are permitted if they do not exceed 45°
degrees of inclination. The total lengths of the two offsets are not
required to meet the 75% percent allowable rule.
Example 3:
Shows a single offset at 45° degrees of inclination and
therefore the lateral length at 10 feet of offset does not have to meet
the 75% percent rule.
In each case the offsets must be supported and firestops must be
positioned wherever the vent must pass through a sub-floor, ceiling
joist or an attic overhang. The vent pipe must terminate vertically
into a listed type vent cap and extend a sufficient height through an
approved roof flashing, roof jack or a roof thimble. At all points the
listed clearances must be maintained.

Vent terminations must be located in accordance with height and
proximity rules of NFPA No. 54 or CAN/CSA B149. These rules
apply to vents at 12 in. diameter or less and require a minimum
height in accordance with the roof pitch and a minimum of 8 ft.
distance from a vertical wall or obstruction (see Figure 11).
If venting horizontally through a side wall becomes necessary, a
listed thimble approved for use with B-type vent must be used.
Check with your local codes before venting through a side wall.
Some codes areas allow the use of existing B-type vent systems if
the system is at or above the recommended diameter of the flue.
The flue connection must be made using listed B-type connectors
and the existing system must be code inspected for damage and
proper installation.
It is not recommended that this appliance be common vented with
an existing gas burning appliance. However, if it becomes necessary
to common vent this appliance, the venting system must be sized
and configured in accordance with the common venting guides
Appendix G of the current National Fuel Gas Code NFPA No. 54/ANSI Z223.1 and in Canada with CAN/CSA B149.

Note:
Before connecting this appliance to an existing vent system
or a common venting system consult with your local architect,
planner, or building official.
WARNING: This appliance must be properly connected to a system and must not be connected to a
chimney flue servicing a separate solid fuel burning
appliance.
CHECKING FOR PROPER VENTING
After completing and checking the electrical, gas and vent connections, follow the lighting instructions and allow the main burner to run
for approximately 5 minutes. Hold a lighted match or cigarette near
the top edge of the fireplace opening and play it along the entire length
of the opening (see Figure 11). Proper venting should tend to draw the
flame or smoke into the appliance. Improper venting or escaping of
spillage of burned gas, is indicated when the match flickers or goes
out. Smoke from a cigarette will also tend to disperse away from the
appliance.
If the appliance is found to be improperly venting, shut it off and
notify your installer or a qualified service agency to inspect the
venting system.
NOTICE: This appliance is equipped with a vent
safety shutoff switch which will shut down the appliance in the case of a venting problem. Do not bypass
the vent safety switch. If the appliance should shut
down, contact a qualified installer, service agency, or
your gas supplier to have the vent inspected before
operating.
Check this area along
the entire top edge of the
fireplace opening. Smoke
or flame should be drawn
into the appliance
opening.

DESA recommends that a black iron gas line be routed from the gas
source, through a sediment trap (shown in Figure 19), and into the
appliance, Once connected through the appliance, a flexible gas line
may be used for ease of installation to gas control valve (see Figure 20).
Before connecting the black iron gas line to the inside of the appliance
a sediment trap must be included outside the appliance between the gas
line and the gas shutoff valve. It must extend down three (3) inches
beyond the center of the pipe. Prepare incoming black iron gas line with
teflon tape or pipe joint compound (Check with local building codes).
CAUTION: Compounds used on threaded joints
of gas piping shall be resistant to the action of
Liquefied Petroleum (LP or propane), and should be
applied lightly to ensure excess sealant does not
enter the gas line.
WARNING: All gas piping and connections must
be tested for leaks after the installation is completed.
After ensuring that the gas valve is on, apply a
noncorrosive leak detection solution to all connections and joints. If bubbles appear, leaks can be
detected and corrected.
Do not use an open flame for leak testing and do not
operate any appliance if a leak is detected.
Complete your gas installation by connecting incoming gas line
with flexible gas line. Secure tightly with wrench but DO NOT
OVERTIGHTEN.

TROUBLESHOOTING
TROUBLESHOOTING
Continued
OBSERVED PROBLEM
Pilot goes out when wall switch is ON
Spark ignitor will not light pilot after repeated triggering of red button
POSSIBLE CAUSE
1. Millivolt output on thermopile too high
1. Defective ignitor (no spark at electrode)
2. Defective pilot or misaligned electrode
at pilot (spark at electrode)
3. No gas or low gas pressure
4. If using propane/LP gas, no propane/LP
gas in tank
REMEDY
1. Replace thermopile
1. Check for spark at the electrode and pilot; if no spark and electrode wire is
properly connected, replace ignitor
2. Using a match, light pilot. If pilot lights,
turn off pilot and trigger the red button
again. If pilot lights, an improper gas/
air mixture caused the improper lighting and a longer purge period is recommended. If pilot will not light, check gap
at electrode and pilot. Gap should be 1/
8" to have a strong spark. If okay, replace pilot
3. A)Check remote shut off valves from
fireplace. Usually there is a valve near the
fireplace and sometimes there is a valve
near the main. There can be more than one
(1) valve between the fireplace and main
B)Low pressure can be caused by a
variety of situations such as bent line, too
narrow diameter of pipe, or even low line
pressure. Check for kinked lines. If none,
consult with plumber or gas supplier
4. Check propane/LP supply and contact
local propane/LP supplier

WARRANTY INFORMATION
KEEP THIS WARRANTY
Model
Serial No.
Date Purchased
Always specify model and serial numbers when communicating with the factory.
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard written
warranty. We make no other warranty, expressed or implied.
LIMITED WARRANTY B-VENT FIREPLACE
DESA warrants this product to be free from defects in materials and components for four (4) years from the date of first purchase, provided
that the product has been properly installed, operated and maintained in accordance with all applicable instructions. To make a claim under
this warranty the Bill of Sale or cancelled check must be presented.
This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore this heater to proper
operating condition and an allowance for labor when provided by a DESA Authorized Service Center. Warranty part(s) MUST be obtained
through authorized dealers of this product and/or DESA who will provide original factory replacement parts. Failure to use original factory
replacement parts voids this warranty. The heater MUST be installed by a qualified installer in accordance with all local codes and
instructions furnished with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become damaged
as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation. Travel, diagnostic cost, labor,
transportation and any and all such other costs related to repairing a defective heater will be the responsibility of the owner.
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE PRODUCT;
THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES AND LIMITS THE DURATION
OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE TO FOUR (4) YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA’S
LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA SHALL NOT BE LIABLE FOR ANY
OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.
Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or consequential
damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
