AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
not be installed in a room or space
unless the required volume of
indoor combustion air is provided
by the method described in the
National Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International
Fuel Gas Code, or applicable
local codes. Read the following
instructions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Today’s homes are built more energy efcient
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
efcient, 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, replaces, 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.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 6 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 dened as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10
less with openings 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 oors, 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 8.
If your home does not meet all of the three
criteria above, proceed to Determining Fresh-
Air Flow For Heater Location, page 7.
Conned and Unconned Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA 54 denes a conned 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 ag-
gregate input rating of all appliances installed
in that space and an unconned space as a
space whose volume is not 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. Rooms communicating
directly with the space in which the appliances
are installed*, through openings not furnished
with doors, are considered a part of the unconned space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.

1. Determine the volume of the space (length
x width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
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. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
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.
Vent-free replace __________ Btu/HrGas water heater* __________Btu/Hr
Gas furnace __________ Btu/Hr
Vented gas heater __________ Btu/Hr
Gas replace 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.
Example:
Gas water heater _________ Btu/HrVent-free replace + ________ Btu/Hr
Total _________ = Btu/
40,000
33,000
73,000
Hr
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)
73,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the above example is a conned
space because the actual Btu/Hr used is more
than the maximum Btu/Hr the space can sup-
port. 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 unconned space, remove door to adjoining room or add ventilation grills between
rooms. See Ventilation Air From Inside
Building, page 8.
126854-01A7
www.Astria.US.com
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 8.
C. Install a lower Btu/Hr replace, if lower Btu/
Hr size makes room unconned.
If the actual Btu/Hr used is less than the maxi-
mum Btu/Hr the space can support, the space is
an unconned space. You will need no additional
fresh air ventilation.
WARNING: If the area in which
the heater may be operated does
not meet the required volume for
indoor combustion air, combustion and ventilation air shall be
provided by one of the methods
described in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54,
the International Fuel Gas Code,
or applicable local codes.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor 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).

ACCESSORY FOR VENTED
OPERATION
Note: When used as a vented heater, appliance must be installed only in a solid-fuel
burning replace with a working ue and constructed of noncombustible material.
For Massachusetts Residents Only: Installation of this vented gas log set in the Com-
monwealth of Massachusetts requires the
damper be permanently removed or welded
in the fully open position.
If your heater is a manually-controlled model,
you may use this heater as a vented product.
There are three reasons for operating your
heater in the vented mode.
1. The replace does not meet the clearance
to combustibles requirements for vent-free
operation.
2. State or local codes do not permit ventfree operation.
3. You prefer vented operation.

If reasons number 1 or 2 apply to you,
you must permanently open chimney ue
damper. You must install the damper clamp
accessory (to order, see Accessories, page
34). This will insure vented operation (see Figure 10). The damper clamp will keep damper
open. Installation instructions are included
with clamp accessory.

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 3/8" NPT (National
Pipe Thread) inlet connection
to the pressure regulator.
WARNING: A qualied service
person must connect heater to
gas supply. Follow all local codes.
CAUTION: Never connect
propane/LP replace directly
to the propane/LP supply. This
heater requires an external regulator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* A equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge
connection. Purchase the optional equipment
shutoff valve from your dealer.
For propane/LP units, 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" of water. If you do not reduce incoming gas pressure, heater regulator
damage could occur. Install external regulator
with the vent pointing down as shown in Figure
13. Pointing the vent down protects it from
freezing rain or sleet.

WARNING: Never connect
natural gas replace to private
(non-utility) gas wells. This gas
is commonly known as wellhead
gas.
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
1/2" diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
volume will occur.
Installation must include an 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 14).
IMPORTANT: Install equipment shutoff valve
in an accessible location. The equipment
shutoff valve is for turning on or shutting off
the gas to the appliance.
Check your building codes for any special
requirements for locating equipment shutoff
valve to replaces.
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: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install a sediment trap
in supply line as shown in Figure 14. Locate
sediment trap where it is within reach for
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.

INSPECTING BURNERS
Check pilot ame pattern and burner ame
patterns often.
PILOT FLAME PATTERN
Figure 34 shows a correct pilot ame pattern.
Figure 35 shows an incorrect pilot ame pattern. The incorrect pilot ame is not touching
the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools,
the heater will shut down.
If pilot ame pattern is incorrect, as shown
in Figure 35
• turn heater off (see To Turn Off Gas to Appliance, page 21)
• see Troubleshooting, page 24
Note: The pilot ame on natural gas units will
have a slight curve, but ame should be blue
and have no yellow or orange color.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes
in the tting at the burner entrance. These
holes may become blocked with dust or lint.
Periodically inspect these holes for any blockage and clean if needed. Blocked air holes
will create soot.
CLEANING AND MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burners and
circulating air passageways of
heater clean. Inspect these areas
of heater before each use. Have
heater inspected yearly by a quali-
ed service person. Heater may
need more frequent cleaning due
to excessive lint from carpeting,
pet hair, bedding material, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result
in sooting and property damage.

MAIN BURNER
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame
holes should be open with yellow ame present. All round burner ame holes should be
open with a small blue ame present. Some
burner ame holes may become blocked by
debris or rust, with no ame present. If so,
turn off heater and let cool. Remove blockage.
Blocked burner ame holes will create soot.
BURNER ORIFICE HOLDER AND
PILOT AIR INLET HOLE
The primary air inlet holes allow the proper
amount of air to mix with the gas. This provides
a clean burning ame. Keep these holes clear
of dust, dirt, lint and pet hair. Clean these air in-
let 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 qualied service person.
We also recommend that you keep the burner
tube and pilot assembly clean and free of dust
and dirt. To clean these parts we recommend
using compressed air no greater than 30 PSI.
Your local computer store, hardware store or
home center may carry compressed air in a
can. If using compressed air in a can, please
follow the directions on the can. If you don’t
follow directions on the can, you could dam-
age the pilot assembly.
