FRESH AIR
FOR
COMBUSTION
AND
WARNING
WARNING ICON
G
001
This heater must have fresh air for proper operation. If not, poor
fuel combustion could result. Read the following instructions to
insure proper fresh air for this and other fuel-burning appliances
in your home.
VENTILATION
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 fuel-burning appliances.
PRODUCING ADEQUATE 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 5 through 8 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 continu-
ous water vapor retarder with a rating of one perm or less with open-
ings 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 addi-
tional fresh air. See Ventilation Air From Outdoors, page 8.
If your home does not meet all of the three criteria above, continue reading.
Unconfined Space
An unconfined space has a minimum air volume of 50 cubic feet for each 1000
BTU/Hr input rating of all appliances in the space (cubic feet equals length x
width x height of space). Include adjoining rooms only if there are doorless
passageways or ventilation grills between the rooms.
Confined Space
A confined space has an air volume of less than 50 cubic feet for each 1000
BTU/Hr input rating of all appliances in the space (cubic feet equals length x
width x height of space). Include adjoining rooms only if there are doorless
passageways or ventilation grills between the rooms.

FOR
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined space.
COMBUSTION
AND
Space: Includes the room in which you will install heater plus any adjoining rooms with
doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space (length x width x height).
VENTILATION
Length x Width x Height =
___________________
cu. ft. (volume of space)
Continued
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. 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)
3. Add the BTU/Hr of all fuel burning appliances in the space.

_________________ BTU/Hr (actual amount of BTU/Hr used)
Example: 51,200 BTU/Hr (maximum the space can support)
58,000 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 7.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8.
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
You must provide additional ventilation air in a confined space.

Never connect heater directly to the propane supply. This heater
requires an external regulator (not supplied). Install the external
regulator between the heater and propane 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 can 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.

Use only new, black iron or steel pipe. Internally-tinned copper
tubing may be used in certain areas. Check your local codes. Use
pipe of 1/2" 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, 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 15).
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

repairs are not reimbursable under this warranty and are 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 two years from the date of first purchase; and DESA

consequential damages, so the above limitation of implied warranties, or exclusion, or limitation of damages may not
apply to you.
