FRESH AIR FOR
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from
National Fuel Gas Code. NFPA
54/ANS 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 Construction
2. Unconfined Space
3. Confined Space
The information on pages 4
through 6 will help you classify
your space and provide adequate
ventilation.

insure proper fresh air for this
and ot h er f uel- b urn i ng
appliances in your home.
Confined and
Unconfined Space
The National Fuel Gas Code ANS
Z223.1
defines a confined space
as a space whose volume is less
than 50 cubic feet per 1,000 Btu per
hour ( 4 . 8 m
3
per kw) o f t h e
aggre gat e in put rating of a ll
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 m
3
per k w) of the
aggre gat e in put rating of a ll
appliances installed in that space.
Rooms communicating directly with
t h e s p a ce i n w h ich t h e
appliances are installed*, through
openings not furnished with doors,
ar e consi de red a par t of the
unconfined space.
This heater shall not be installed
in a confined space or unusually

A d j o i n i n g r o o m s a r e
communicating only if there are
doorless passageways or ventilation grills between them.
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, ANS Z223.1, Section 5.3
or applicable local codes.
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-s ec- m2) o r le ss with
openings gasketed or sealed
and
b. weather stripping has been
ad ded on ope na bl e win dows and
doors
and
c. caulking or sealants are applied
to areas such as joints around
window and door frames, between
sole p lates and floors, between
wall-ceil ing 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.
If your home does not meet all of
the t hre e cri ter ia abo ve, see
Determini ng Fresh-Ai r Flow for
Heater Location, page 5.
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.
1. Determine the volume of the space (length
×
width×height).
Length×Width×Height=
cu.ft. (volume of space)
Example: Space size20ft. (length)×16ft.( width)×8ft. (ceiling height)=2560cu. 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)
COMBUSTION AND
VENTILATION

WARNING: Rework worksheet, adding t he spac e of the a djo ini ng
unconfined space. The combined spaces
must have enough fresh air to supply all
appliances in both spaces.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconfined space. When ventilating to an
ad joining unconfin ed s pace, 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/ANS Z223.1. Section 5.3, Air
for Combustion and Ventilation
for required
size of ventilation grills or ducts
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:
Gas water heater 40,000 Btu/Hr
Vent free heater
+ 18,000 Btu/Hr
Total = 58,000 Btu/Hr
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
*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
: 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 5.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors
, page 6 .
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.

external regulator between the
heater and propane/LP supply.
*A CSA/AGA design-certified equipment shutoff valve with 1/8
" NPT tap is
an acceptable alternative to test gauge connection. Purchase the CSA/AGA
design-certified equipment shutoff valve from your dealer.
IMPORTANT: Install an equipment
shutoff v al ve in an access ible
location. The equ ipment shut off
valve is for turning on or shutting
off the gas to the appliance.
Install sediment trap in supply line
as shown in Figure 14. L ocate
sediment trap where it is within
reac h for c lean i n g. Lo c ate
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
ins t alle d wr ong , he ater ma y
not run properly.
IM PORTANT
: Hold pr es sure
regu l ator wit h wre n ch when
conne cting it to gas piping and/or
fittings.
CAUTION: Use pipe joint
se alant that is resis ta nt to
liquid petroleum (LP) gas.
Figure 14 -Gas Connection
The installer must supply an
external regulato r. The extern al
regulator will reduce incoming gas
p r e s s u r e . Yo u m u s t r e d u c e
incoming gas pressure to between
11 and 13 inches of water. If you
do n ot redu ce inco min g gas
pressure, heater regulator damage
could occur . I n s tall ext e r n a l
regulator with the vent pointing
down as shown in Fi gure 13.
Pointing the vent down protects it
from freezing rain or sleet.

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 of large enough
diameter to allow proper gas volume
to heater. If pipe is too small,
undue loss of pressure will occur.
Insta llati on mu st includ e an
equipment shutoff valve, union,
and plugged 1/8
" NPT tap. Locate
NPT tap within reach for test gauge
ho ok up . NPT t ap must b e
upstream from heater(see Figure 14).
Apply pipe joint sealant lightly to
male threads. This will prevent
excess seal ant from going into
pipe. Excess sealant in pipe could
result in clogged heater valves.
r
Typical Inlet Pipe Diameters
All models up to 20,000 BTU’s use
3/8’’ or greater pipe;
All models 25,000 BTU’s and higher,
use 1/2” or greater pipe.
