PRODUCT FEATURES
**SAFETY PILOT
**
This heater has a pilot with an Oxygen Depletion Sensor Shutoff System (ODS). The ODS/pilot is a required feature for ventfree 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 a confined space unless provisions are provided for adequate combustion and ventilation air. Read the following instructions 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
appliances. This will insure proper venting of vented fuelburning appliances.
PROVIDING ADEQUATE VENTILATION
The following is exerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Ventilation. All spaces in homes fall into
one of the three following ventilation classifications:
1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.
The information on pages 4 and 5 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.
Unusually tight construction is defined as construction where:
a. walls and ceilings exposed to the outside atmosphere have a continuous
water vapor retarder with a rating of one perm (6×10-11 kg per pa-sec-m2 ) or
less with openings gasketed or sealed and
b. weather stripping has been added on openable windows and doors and
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
additional 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 Heater Location.
Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ2123.1, 1992 Section 5.3) 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 a space whose volume is not 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. 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.
- Adjoining rooms are communicating only if there are doorless passageways or ventilation grills between them.
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space:
Use this worksheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install heater plus any
adjoining rooms with doorless passageways or ventilation grills between the
rooms.
-
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. -
Divide the space volume by 50 cubic feet to determine the maximum Btu/ Hr the space can support.
_____ (volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support) -
Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater _ Btu/Hr
Gas water heater ____ Btu/Hr
Gas furnace ____ Btu/Hr
Vented gas heater ____ Btu/Hr
Gas fireplace logs ____ Btu/Hr
Other gas
appliances + ___ Btu/Hr
Total = ____ Btu/Hr
Example: Gas water heater
40,000 Btu/Hr
Vent-free heater + 10,000 Btu/Hr
Total = 50,000 Btu/Hr
- Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.
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: 46,100 Btu/Hr (maximum the space can support)
50,000 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 5.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors,
page 5.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room
unconfined.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can
support, the space is an unconfined space. You will need no additional fresh
air ventilation.
WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3 or applicable local codes.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining unconfined space. When
ventilating to an adjoining unconfined space, you must provide two permanent
openings: one within 12″ of the ceiling and one within 12″ of the floor on the
wall connecting the two spaces (see options 1 and 2, Figure 2). You can also
remove door into adjoining room (see option 3, Figure 2). Follow the National
Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion and
Ventilation for required size of ventilation grills or ducts.
WARNING: Rework worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.
Figure 2 – Ventilation Air from Inside Building
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide
two permanent openings: one within 12″ of the ceiling and one within 12″ of
the floor. Connect these items directly to the outdoors or spaces open to the
outdoors. These spaces include attics and crawl spaces.
IMPORTANT: Do not provide openings for inlet or outlet air into attic if
attic has a thermostat-controlled power vent. Heated air entering the attic
will activate the power vent.

- Drill hole at marked location using 9/ 64″ drill bit.
- Insert mounting screw into wall stud.
- Tighten screw until 1/16″ space (thickness of penny) is between screwhead and wall.
Attaching to wall anchor method
Follow instructions below to attach mounting screws to hollow walls (wall areas between studs) or solid walls (concrete or masonry).
-
Drill holes at marked locations using
5/16″ drill bit. For solid walls (concrete or masonry), drill at least 1 1/4″ deep. -
Fold wall anchor (see Figure 6).
Figure 6 – Folding Anchor
-
Insert wall anchor (wings first) into hole. Tap anchor flush to wall.
-
For thin walls (1/2″ or less), insert red key into wall anchor. Push red key to “pop” open anchor wings (see Figure 7). IMPORTANT: Do not hammer key! For thick walls (over 1/2″ thick) or solid walls, do not pop open wings.
-
Tighten two screws until 1/16″ space (thickness of penny) is between screwheads and wall (see Figure 8).
Figure 8 – Tightening Anchors
Placing Heater On Mounting Screws
- Locate two keyhole slots on back panel of heater (see Figure 9).
- Place large openings of slots over screwheads. Slide heater down until screws are in small portion of slots.
Figure 9 – Location Of Keyhole Slots On Back Panel Of Heate
Removing Front Panel Of Heater
- Remove two screws near bottom corners of front panel.
- Lift straight up on grill guard until it stops. Grill guard will slide up about 1/4″.
- Pull bottom of front panel forward, then down.
Figure 10 – Removing Front Panel Of Heater
Installing Bottom Mounting Screw
- Locate bottom mounting hole. This hole is near bottom on back panel of heater (see Figure 11).
- Mark screw location on wall.
- Remove heater from wall.
- If installing bottom mounting screw into hollow or solid wall, install wall anchor. Follow steps 1 through 5 under Attaching To Wall Anchor Method. If installing bottom mounting screw into wall stud, drill hole at marked location using 9/64″ drill bit.
- Replace heater on wall.
- Insert bottom anchor screw through back panel into bottom anchor or drilled hole (see Figure 11).
- Tighten screw until heater is firmly secured to wall. Do not over tighten.
Note: Do not replace front panel at this time. Replace front panel after making gas connections and checking for leaks (see pages 8 and 9).
Figure 11 – Installing Bottom Mounting Screw
CONNECTING TO GAS SUPPLY
NOTICE: A qualified service person must connect heater to gas supply. Follow all local codes.
CAUTION: Never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply
The installer must supply an external regulator. 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 pointing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.
Figure 12 – External Regulator With Vent Pointing Down
CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe 3/8″ diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.
Installation must include a manual shutoff valve, ground joint 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).
Apply pipe joint sealant lightly to male threads. This will prevent excess
sealant from going into pipe. Excess sealant in pipe could result in clogged
heater valves.
CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within reach for cleaning. 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
IMPORTANT: Hold pressure regulator with wrench when connecting it to gas piping and/or fittings.
Figure 13 – Gas Connection
- An A.G.A. design-certified manual shutoff valve with 1/8″ NPT tap is an acceptable alternative to test gauge connection. Purchase the optional A.G.A. design certified manual shutoff valve from your dealer. See Accessory, page 15.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for leaks after installing
or servicing. Correct all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply a mixture of
liquid soap and water to all joints. Bubbles forming show a leak. Correct all
leaks at once.
CAUTION: Make sure external regulator has been installed between
propane/LP supply and heater. See guidelines under Connecting to Gas Supply,
page 8

LIMITED WARRANTY
VANGUARD VENT-FREE RESIDENTIAL GAS HEATER S
DESA International warrants this product to be free from defects in materials
and components for three (3) 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 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 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 THREE (3) YEARS ON ALL COMPONENTS 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. For information about this warranty
