AIR FOR COMBUSTION AND  
VENTILATION  
Unusually tight construction is defined as construction  
where:  
WARNING: This heater shall not be installed in a  
confined space or unusually tight construction un-  
lessprovisionsareprovidedforadequatecombustion  
and ventilation air. Read the following instructions to  
insure proper fresh air for this and other fuel-burning  
appliances in your home.  
a. walls and ceilings exposed to the outside atmosphere  
have a continuous water vapor retarder with a rating  
of one perm (6x10-11 kg per pa-sec-m2) or less with  
openings gasketed or sealed and  
b. weather stripping has been added on openable win-  
dows and doors and  
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.  
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 6.  
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.  
If your home does not meet all of the three criteria above,  
proceed to Determining Fresh-Air Flow For Heater Loca-  
tion, page 5.

fuel-burning appliances.  
Confined and Unconfined Space  
PROVIDING ADEQUATE VENTILATION  
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.  
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  
* Adjoining rooms are communicating only if there are doorless  
passageways or ventilation grills between them.  
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.

4. Compare the maximum Btu/Hr the space can support with the actual  
amount of Btu/Hr used.  
DETERMINING FRESH-AIR FLOW FOR

__________________ 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)

Determining if You Have a Confined or  
Unconfined Space  
Use this work sheet to determine if you have a confined or unconfined space.  
Space:Includestheroominwhichyouwillinstallheaterplusanyadjoining  
rooms with doorless passageways or ventilation grills between the rooms.  
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:  
1. Determine the volume of the space (length x width x height).  
Length x Width x Height = ___________ cu. ft. (volume of space)  
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.  
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 open-  
ings, add the volume of these rooms to the total volume of the space.  
B. Vent room directly to the outdoors. See Ventilation Air From Out-  
doors, page 6.  
2. Multiply the space volume by 20 to determine the maximum Btu/Hr  
the space can support.  
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room un-  
confined.  
__________ (volume of space) x 20 = (Maximum Btu/Hr the space  
can support)  
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.  
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.  
WARNING: If the area in which the heater may be  
operated is smaller than that defined as an uncon-  
fined space or if the building is of unusually tight  
construction,provideadequatecombustionandven-  
tilation air by one of the methods described in the

VN30(T), VP26(T), VN25IT, and VP22IT - 1/2" or greater  
WARNING: This appliance requires a 3/8" NPT  
(National Pipe Thread) inlet connection to the pres-  
sure regulator.  
Installation must include 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 15).  
WARNING: A qualified service person must con-  
nect heater to gas supply. Follow all local codes.  
IMPORTANT: Install an equipment shutoff valve in an accessible  
location. The equipment shutoff valve is for turning on or shutting  
off the gas to the appliance.  
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: For natural gas, never connect heater  
to private (non-utility) gas wells. This gas is com-  
monly known as wellhead gas.  
IMPORTANT: For natural gas, check gas line pressure before  
connecting heater to gas line. Gas line pressure must be no greater  
than 14 inches of water. If gas line pressure is higher, heater  
regulator damage could occur.  
WARNING: Use pipe joint sealant that is resistant  
to liquid petroleum (LP) gas.  
We recommend that you install a sediment trap in supply line as  
showninFigure15.Locatesedimenttrapwhereitiswithinreachfor  
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: For propane/LP gas, 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 pro-  
pane/LP supply.  
IMPORTANT: Hold the pressure regulator with wrench when

THERMOSTAT OPERATION  
1. Slightly press in plaque control knob on right side of heater  
The thermostatic control used on these models differs from  
standard thermostats. Standard thermostats simply turn on  
and off the burner. The thermostat used on this heater senses  
the room temperature. At times the room may exceed the set  
temperature.Ifso,theburnerwillshutoff.Theburnerwillcycle  
back on when room temperature drops below the set tempera-  
ture. Forstandardmodels(T), thecontrolknobcanbesettoany

1, 2, 3, or 4 locked positions for the desired comfort level. The  
number of plaques selected will turn off and on.  
and turn counterclockwise  
to the desired position.  
C-clockwise  
IMPORTANT: Release downward pressure while turning  
control knob. Control knob will lock at the desired position.  
2. For standard models (T), turn thermostat control knob on  
left side of heater to any setting between LO and HI. For  
infrastat models (IT), set thermostat control knob at the 1,  
2, 3, or 4, locked positions. Note: When burners cycle on,  
(from LO to HI or one locked positions to another) a “click”  
will be heard. When the burners light, a “whoosh” noise  
will be heard.

INSPECTING HEATER  
Check pilot flame pattern and burner flame pattern often.  
PILOT FLAME PATTERN  
Figure 27 shows a correct pilot flame pattern. Figure 28 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.  
CAUTION: You must keep control areas, burner,  
and circulating air passageways of heater clean. In-  
spect these areas of heater before each use. Have  
heater inspected yearly by a qualified service person.

ODS/PILOT AND BURNER  
If pilot flame pattern is incorrect, as shown in Figure 28  
• turn heater off (see To Turn Off Gas to Appliance, page 14 or 16,  
• Use a vacuum cleaner, pressurized air, or small, soft bristled  
brush to clean.  
depending on your model)  
• see Troubleshooting, pages 19 through 21  
CLEANING BURNER PILOT AIR INLET  
The primary air inlet holes allow the proper amount of air to mix with  
the gas. This provides a clean burning flame. Keep these holes clear  
of dust, dirt, and lint. Clean these air inlet holes prior to each heating  
season. Blocked air holes will create soot. We recommend that you  
clean the unit every three months during operation and have heater  
inspected yearly by a qualified service person.  
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.

Serial No.

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  
VANGUARD VENT-FREE INFRARED GAS HEATERS  
DESA International 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 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 FOUR (4) 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.
