AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This heater shall
not be installed In aconfined
space unless provisions are pro-
vided for adequate combustion
and ventilation air. Read the fol-
lowing instructions to insure
proper fresh air for this and other
fuel-burning appliances in your
home.
Today's homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatloss inhomes. Home owners
weather sl_p and caulk aroundwindows and
doorstokeepthecdd ah"outandthewarm air
in. During heating months, home owners
want their homes as airtight as possible.
While itis 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 com-
bustion and ventilation.
Exhaustfans,fireplaces, clothes dryers,and
fuel burningappfiances draw airfrom the
house to operate. You must provide ad-
equateflesh air for these appliances.This
will insure proper ventingof vented fuel-
burningappliances.
PROVIDING ADEQUATE
VENTILATION
The following is excerpts 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 Construction
2. Unconfined Space
3. Confined Space
The information on pages 4through 6 will
help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and win-
dows may provide enough flesh air for
combustion and ventilation. However, in
buildings of unusually tight construction,
you must provide additional fresh air.
Unusually tight construction is de-
fined as construction where:
a. walls and celllngs exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one penn (6 x 10-11kg
per pa-sec-nd) or less with open-
Ings gasketad or sealed and
b. weather stripping has been
added on openable windows and
doors and
€. caulldng or sealants are applied
to areas such as Joints around
window and door frames, be-
tween sole plates and floors, be-
tween wall-ceiling Joints, be-
tween wall panels, at penetra-
tions for plumbing, electrical, and
gas lines, and st other openings.
ff your home meets all of the three
¢riterle above, you must provide ad-
ditional fresh air. See Ventilation Air
From Outdoors, page 6.
If your home does not meet all of the
three ¢dteda above, proceed to Dater.
mining Fresh-Air Flow for Heater Lo-
cation, page S.
Confined and Unconfined Space
The National Fuel Gas Code (ANSI Z223.1,
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 m3per
kw) of the aggregate input rating of all
appLiances installed in that space and an
unconfialng space as a space whose volume
is not less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3per kw) of the aggregate
input rating of all appliances installed in that
space. Rooms communicating directly with
the space in which the appliances are in-
stalled*, through openings not furnished
with doors, are considered a part of the
unconfined space.
This heater shall not be installed in a con-
fined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
*Adjoiningroomsare communicatingonly
ifthere are doorless passageways or ventila-
tion 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 installheater plus any adjoining rooms with doorless passageway sor ventilation gillls between
the rooms.
1. Determine the volume of the space (length x width x height).
Length xWidth x Height = cu. ft. (volume of space)
Example: Space size 20 ft, (length) x 16 ft. (width) x 8ft, (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

*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.
Bm/Hr (maximum the space can support)
Btu/Hr (actual amount of Btu/Hr used)
Example: 51,200 Btu/Hr (maximum the spacecansupport)
60,000 Btu/Hr (actual amount of Btu/Hr used)
The space intbe above example is aconfined 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 adjoin-
hagroom or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.
B. VeatroomcYu'ecflytotheoutdoors. SeeVentilationAirFromOutdoors, page6.
C. Install a lower Btu/Hr heater, ff lower Btu/Hr size makes room unconfined.
Iftbe 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
adflitional fresh airventilation.

CONNECTING TO GAS
SUPPLY
NOTICE: A qualified service per-
son 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 be-
tween the heater and propane/LP
supply.
The installer must supply an external regu-
lator. 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 incom-
ing 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.
_IL CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-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.
Typical Inlet Pipe Diameters
20,000 Btu/Hr models 3/8" or greater
30,000 Btu/Hr models 1/2" or greater
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).
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.
Pressure
Regulator
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
Install sediment trap in supply line as shown
in Figure 13. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment 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 pip-
ing and/or fittings.

INSPECTING
BURNER
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 18 shows a correct pilot flame pat-
tern. Figure 19 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.
If pilot flame pattern is incorrect, as shown
in Figure 19
•turn heater off (see To Turn Off Gas to
Appliance,)
•see Troubleshooting, pages 14 through 16

BURNER FLAME PATTERN
Figure 20 shows a correct burner flame
pattern. Figure 21 shows anincorrect burner
flame pattern. The incorrect burner flame
pattern shows yellow tipping of the flame. It
also shows the flame higher than 1/2 the
heat shield height.
If burner flame pattern is incorrect, as shown
in Figure 21
•turn heater off(see To Turn OffGas to
Appliance, page 12).
• see Troubleshooting, pages 14through 16
_i, WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If burner flame pat-
tern shows yellow tipping, follow
instructions at bottom of this
page.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles enter the
heater end burn causing brief
patches of orange flame.
