PRODUCT FEATURES

OPERATION This heater is clean burning. It requires no outside venting. There is no heat loss out a vent or up a chimeney. 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 decora tive (ANSI Z21.60) product by opening the ﬂue damper (Non-Thermosta models only).

SAFETY DEVICE

This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shut off system. The ODS/pilot is a required feature for vent-free room heaters. The ODS/pilot shuts off the heater if there is not enough fresh air.

PIEZO IGNITION SYSTEM

This heater has a piezo ignitor. This system requires no matches, batteries, or other sources to light heater.

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in conﬁned space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. Read the following in structions to insure proper fresh air for this and other fuel-burning appliances in your home.

Today’s homes are built more energy efﬁcient than ever. New materials, increased insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.

While it is good to make your home energy efﬁcient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper combustion and ventilation.

Exhaust fans, ﬁreplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these ap pliances. This will insure proper venting of vented fuel-burning appliances.

PROVIDING ADEQUATE VENTILATION

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

3. Conﬁned Space

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.

-

For more information, visit www.desatech.com

114745-01

AIR FOR COMBUSTION AND VENTILATION

Continued

Unusually tight construction is deﬁned as construction where:

A.Walls and ceilings exposed to the outside atmosphere have a con tinuous water vapor retarder with a rating of one perm (6 x 10 pa-sec-m

B. weather stripping has been added on openable windows and doors

C.caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and ﬂoors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you must provide ad ditional fresh air. See Ventilation Air From Outdoors, page 5.

If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow For Appliance Location, below.

Conﬁned and Unconﬁned Space

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 m space and an unconﬁned space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m

DETERMINING FRESH-AIR FLOW FOR APPLIANCE LOCATION

Determining if You Have a Conﬁned or Unconﬁned Space

Use this work sheet to determine if you have a conﬁned or unconﬁned space.

Space: Includes the room in which you will install appliance plus any adjoining rooms with odorless passageways or ventilation grills between the rooms.

1.Determine the volume of the space (length x width x height).

Length x Width x Height = _______________ cu. ft. (volume of space)

Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height)

2560 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.

2.Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support.

____________(volume of space) x 20 = (Maximum Btu/Hr the space can support)

Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum Btu/Hr the space can support)

3.Add the Btu/Hr of all fuel burning appliances in the space.

Vent-free appliance _____________

Gas water appliance* _____________ Btu/Hr

Gas furnace _____________ Btu/Hr

Vented gas appliance _____________ Btu/Hr

Gas ﬁreplace logs _____________

Other gas appliances* + _____________

Total = _____________ Btu/Hr

* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.

Example:

Gas water appliance _____________ Btu/Hr

Vent-free appliance + _____________

Total = _____________

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)

_________

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:

A.Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconﬁned space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.

B.Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.

C.Install a lower Btu/Hr appliance, if lower Btu/Hr size makes room unconﬁned.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can sup port, the space is an unconﬁned space. You will need no additional fresh air ventilation.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION

Note: When used as a vented decorative, appliance must be installed only in a solid-fuel burning ﬁreplace with a working ﬂue and constructed of non combustible material.

If your heater is a non-thermostatically-controlled model, you may use this heater as a vented product. There are three reasons for operating your heater in the vented mode.

1. The ﬁreplace does not meet the clearance to combustibles requirements for vent-free operation.

2. State or local codes do not permit vent-free operation.

3. You prefer vented operation.

If reasons number 1 or 2 above apply to you, you must permanently open chimney ﬂue damper. You must install the damper clamp accessory (to order, see Accessories, page 27). This will insure vented operation (see Figure

10). The damper clamp will keep damper open. Installation instructions are

included with clamp accessory.

See chart below for minimum permanent ﬂue opening you must provide. Attach damper clamp so the minimum permanent ﬂue opening will be maintained at all times.

WARNING: This appliance requires a 3/8" NPT (National Pipe

Thread) inlet connection to the pressure regulator.

WARNING: A qualiﬁed service person must connect heater to gas

supply. Follow all local codes.

CAUTION: Never connect propane/LP ﬁreplace directly to the propane/LP supply. This heater requires an external regulator (not sup plied). Install the external regulator between the heater and propane/LP supply.

WARNING: Never connect natural gas ﬁreplace to private (nonutility) gas wells. This gas is commonly known as wellhead gas.

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

• approved ﬂexible gas line with gas connector (if allowed by local codes) (provided)

* 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 27.

For propane/LP units, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce in coming 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 pointing down as shown in Figure 12. Point ing the vent down protects it from freezing rain or sleet.

Installing Heater Assembly (Cont.)

INSTALLATION

Connecting to Gas Supply

CONNECTING TO GAS SUPPLY

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 Figure 13 page 12, depending on your model).

IMPORTANT: Install equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the ap pliance.

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 pe-

troleum (LP) gas.

We recommend that you install a sediment trap in supply line as shown in Figure 13 page 12, 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. If sediment trap is not installed or is installed wrong, heater may not run properly.

CAUTION: Avoid damage to gas control. Hold gas control with

wrench when connecting it to gas piping and/or ﬁttings.

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

VENT-FREE GAS LOG HEATERS

DESA International 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.

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 International 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 WAR RANTY 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 AND FIVE (5) YEARS ON STAINLESS STEEL BURNERS FROM THE DATE OF FIRST PURCHASE; AND DESA INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA INTERNATIONAL 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.
