PRODUCING ADEQUATE
VENTILATION
This section is for residential or manufactured (mobile) installation
“This heater shall not be installed in a confined space or unusually tight construction unless pro-
visions are adequate combustion and ventilation 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 (4.8m 3 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 (4.8m 3 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.
“WARNING: IF THE AREA IN WHICH THE HEATER MAY BE OPERATED IS
SMALLER THAN THAT DEFINED AS AN UNCONFINED SPACE OR IF THE
BUILDING IS OF UNUSUALLY TIGHT CONSTRUCTION, PROVIDE ADEQUATE
COMBUSTION AND VENTILATION AIR BY ONE OF THE METHODS DESCRIBED
IN THE NATIONAL FUEL GAS CODE, ANSI Z223.1/NFPA 54, SECTION 5.3 OR
APPLICABLE LOCAL CODES.”
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 1 perm (6 x 10-11 kg per pa-sec-m2) or less with openings gasketed or sealed;
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.
NOTE: SOME AREAS IN THE UNITED STATES HAVE HIGHER REQUIREMENTS
FOR CUBIC FEET PER 1000 BTU/ HOUR INPUT. (EX. CINCINNATI, OHIO CODES
REQUIRE 70 CUBIC FEET). CHECK YOUR LOCAL CODE BEFORE
INSTALLATION.
DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
DETERMINE IF YOU HAVE A CONFINED OR UNCONFINED SPACE
Use this worksheet to determine if you have confined or unconfined space.
SPACE: Includes the room in which you will install heater plus adjoining rooms with
doorless passageways or ventilation grills between the rooms.
Page 12

1. Determine the volume of the space (length x width x height).
Length x Width x Height =_________cu.ft.(volume of space)
EXAMPLE: 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
51200 (maximum BTU/Hr the space can support)
3. 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 40000 BTU/Hr
Vent-free heater + 18000 BTU/Hr
Total = 58000 BTU/Hr
*Does 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: 51200 BTU/Hr (maximum the space can support)
58000 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 21.
B. Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 22.
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.
WA R N I N G : YOU MUST PROVIDE ADDITIONAL VENTILATION AIR IN A
CONFINED SPACE
Page 13

VENTILATION AIR
VENTILATION AIR FROM INSIDE BUILDING
This fresh air would come from an adjoining unconfined space. When venting to an adjoining
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 5). You
can also remove door into adjoining room. (See Option 3, Figure 5).
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.
NOTE: Each opening shall have a minimum free area of 1 square inch per 1000 BTU’s per
hour of the total input ratings of all gas utilization equipment in the confined space, but not less
than 100 square inches.
Figure 5: Ventilation Air From Inside Building
NOTE: Drill holes on bottom of pedestal base on each corner. Unit must be fastened to floor
with screws.
Page 14

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. These spaces include attics and crawl spaces. Follow the National
Fuel Gas Code NFPA 54/ANSI Z223.1, Section 4.3, “Air For Combustion and Ventilation” for
required size of ventilation grills or ducts. See Figure 6.
IMPORTANT: Do not provide openings for inlet air into attic if attic has a thermostat-
controlled power vent. Heated air entering the attic will activate the power unit.
WARNING
THIS HEATER MUST HAVE FRESH AIR FOR PROPER OPERATION. IF
NOT, POOR FUEL COMBUSTION COULD RESULT. READ THE
FOLLOWING INSTRUCTIONS TO ENSURE PROPER FRESH AIR FOR
THIS AND OTHER FUEL-BURNING APPLIANCES IN YOUR HOME.

GAS PRESSURE CHECK
Check the inlet pressure to the burner to ensure that it is shown in the table below.
NOTE: The pressure check point is located on the right side of the valve facing burner, for SIT
Millivolt, and the left side for SIT Modulating.
The appliance and its appliance main gas valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of 1/2
psi (3.5kPa).
The appliance must be isolated from the gas supply piping system by closing its equipment shut
-off valve during any pressure testing of the gas supply piping system at test pressures equal to
or less than 1/2 psi (3.5 kPa).

NOTE: On initial installation it may be necessary to bleed out air in the gas lines. Do this by
holding the control knob and turning the knob to the “PILOT” position for about 30 seconds.
To check the regulator pressure, remove the pressure tag plug at the left side of the regulator
facing the heater. The pressure should be checked with the heater burning and the control set
on high. After measuring the pressure, replace the pressure tap plug, ensuring that there are no
leaks.
