The following are excerpts from National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three following ventilation
classifications:
1. Unusually Tight Construction
2. Unconfined Space
PRODUCT FEATURES
OPERATION
3. Confined Space
This heater is clean burning. It requires no outside venting. There is
no heat loss out a vent or up a chimney. Heat is generated by both
realistic flames and glowing coals. This heater is designed for vent-
free operation with flue damper closed. It has been tested and
approved to ANSI Z21.11.2 standard for unvented heaters. State and
local codes in some areas prohibit the use of vent-free heaters. This
heater may also be operated as a vented decorative (ANSI Z21.60)
product by opening the flue damper (Non-Thermostat Models Only).
The information on pages 4 through 6 will help you classify your
space and provide adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough
fresh air for combustion and ventilation. However, in buildings of
unusually tight construction, you must provide additional fresh air.

The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a
confined space as a space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating
of all appliances installed in that space and an unconfined space as
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper
hour (4.8 m3 per kw) of the aggregate input rating of all appliances
installed in that space. Rooms communicating directly with the
space in which the appliances are installed*, through openings not
furnished with doors, are considered a part of the unconfined space.
4. Compare the maximum Btu/Hr the space can support with the actual
amount of Btu/Hr used.
__________________ Btu/Hr (maximum the space can support)
__________________ Btu/Hr (actual amount of Btu/Hr used)
Example: 51,200 Btu/Hr (maximum the space can support)
73,000 Btu/Hr (actual amount of Btu/Hr used)
The space in the above example is a confined space because the actual Btu/
Hr used is more than the maximum Btu/Hr the space can support. You must
provide additional fresh air. Your options are as follows:
* Adjoining rooms are communicating only if there are doorless
passageways or ventilation grills between them.
A. Rework worksheet, adding the space of an adjoining room. If the ex-
tra space provides an unconfined space, remove door to adjoining
room or add ventilation grills between rooms. See Ventilation Air From
Inside Building, page 6.

WARNING: You must secure this heater to fire-
place floor. If not, heater will move when you adjust
controls. Moving heater may cause a gas leak.
Note: When used as a vented heater, appliance must be installed
only in a solid-fuel burning fireplace with a working flue and
constructed of noncombustible material.
If your heater is a manually-controlled model, you may use this
heater as a vented product. There are three reasons for operating
your heater in the vented mode.
WARNING:Ifinstallinginasunkenfireplace,special
care is needed. You must raise the fireplace floor to
allow access to heater control panel. This will insure
adequate air flow and guard against sooting and con-
trolsbeingdamaged.Raisefireplacefloorwithnoncom-
bustible material. Make sure material is secure.
1. The fireplace does not meet the clearance to combustibles re-
quirements for vent-free operation.
2. State or local codes do not permit vent-free operation.
3. You prefer vented operation.
CAUTION: Do not pick up heater base assembly by
burners. This could damage heater. Only handle base
assembly by grates.
If reasons number 1 or 2 above apply to you, you must permanently
open chimney flue damper. You must install the damper clamp
accessory(toorder,seeAccessories,page36).Thiswillinsurevented
operation (see Figure 10). The damper clamp will keep damper open.
Installation instructions are included with clamp accessory.
IMPORTANT: Make sure the heater burners are level. If heater is
not level, heater will not work properly. For thermostat models,
avoid damage to thermostat bulb. Avoid nicks or sharp bends in
thermostat bulb wire. Keep thermostat bulb in mounting bracket
until ready to mount base to floor. See Optional Positioning Of

INSTALLATION
Continued
Installation must include an equipment shutoff valve, union, and
plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from heater (see Figures 16 or
17 page 13, depending on your model).
CONNECTING TO GAS SUPPLY
WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
IMPORTANT: Install equipment shutoff valve in an accessible
location. The equipment shutoff valve is for turning on or shutting
off the gas to the appliance.
WARNING: A qualified service person must con-
nect heater to gas supply. Follow all local codes.
Checkyourbuildingcodesforanyspecialrequirementsforlocating
equipment shutoff valve to fireplaces.
CAUTION: Never connect propane/LP fireplace di-
rectlytothepropane/LPsupply.Thisheaterrequiresan
external regulator (not supplied). Install the external
regulator between the heater and propane/LP supply.
Apply pipe joint sealant lightly to male NPT threads. This will
prevent excess sealant from going into pipe. Excess sealant in pipe
could result in clogged heater valves.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
WARNING:Neverconnectnaturalgasfireplaceto
private (non-utility) gas wells. This gas is commonly
known as wellhead gas.
We recommend that you install a sediment trap in supply line as
shown in Figures 16 or 17 page 13, depending on your model.
Locate sediment trap where it is within reach for cleaning. Install in
piping system between fuel supply and heater. Locate sediment trap
where trapped matter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from going into heater
controls.Ifsedimenttrapisnotinstalledorisinstalledwrong,heater
may not run properly.
Installation Items Needed
Before installing heater, make sure you have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
CAUTION: Avoid damage to regulator. Hold gas
regulator with wrench when connecting it to gas
piping and/or fittings (Variable Manually-Controlled
and Thermostatically-Controlled Models Only).
• approved flexible gas line with gas connector (if allowed by lo-
cal codes) (not provided)
CAUTION:Avoiddamagetogascontrol. Holdgas
control with wrench when connecting it to gas piping
and/or fittings (Remote-Ready Models Only).
* A CSA design-certified equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge connection. Purchase
the optional CSA design-certified equipment shutoff valve from
your dealer. See Accessories, page 36.
External Regulator
Propane/LP
For propane/LP units, the installer must supply an external regula-
tor. The external regulator will reduce incoming gas pressure. You
must reduce incoming gas pressure to between 11 and 14 inches of
water. If you do not reduce incoming gas pressure, heater regulator
damage could occur. Install external regulator with the vent point-
ing down as shown in Figure 15. Pointing the vent down protects it
from freezing rain or sleet.
Supply Tank
CAUTION: Use only new, black iron or steel pipe.
Internally-tinnedcoppertubingmaybeusedincertain
areas. Check your local codes. Use pipe of 1/2" diam-
eter or greater to allow proper gas volume to heater. If
pipe is too small, undue loss of volume will occur.

INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
FRONT BURNER FLAME PATTERN
Figure36showscorrectfrontburnerflamepattern. Figure37shows
incorrect front burner flame pattern. The incorrect burner flame
pattern shows yellow tipping at top of blue flame.
PILOT FLAME PATTERN
Figure 34 shows a correct pilot flame pattern. Figure 35 shows an
incorrect pilot flame pattern. The incorrect pilot flame is not
touching the thermocouple. This will cause the thermocouple to
cool. When the thermocouple cools, the heater will shut down.
WARNING: If yellow tipping occurs, your heater
could produce increased levels of carbon monoxide.
If front burner flame pattern shows yellow tipping,
follow instructions at bottom of this page. Yellow
flame on rear burner is normal.
If pilot flame pattern is incorrect, as shown in Figure 35
• turn heater off (see To Turn Off Gas to Appliance, page 17 [Ther-
mostat-Controlled Models], page 18 [Manually-Controlled
Models], or page 20 [Remote-Ready Models])
NOTICE: Do not mistake orange flames with yellow
tipping. Dirt or other fine particles are burned by
heater, causing brief patches of orange flame.
• see Troubleshooting, pages 24 through 26
Note: The pilot flame on natural gas units will have a slight curve,
but flame should be blue and have no yellow or orange color.
If front burner flame pattern is incorrect, as shown in Figure 37

DESA Heating Products warrants this product to be free from defects in materials and components for four (4) years and five (5) years on stainless
steel burners 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.

through authorized dealers of this product and/or DESA Heating Products 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

DESA HEATING PRODUCTS 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.
