Determining
Fresh-Air Flow For Heater Location
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 m3per 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 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 installed*, through openings not furnished
with doors, are considered a part of the un-
conned space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION
Use this work sheet to determine if you have
a conned or unconned space.
Includes the room in which you will install

less passageways or ventilation grills between
the rooms.

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. Dur-
ing 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 ap-
pliances 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.
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.
The air that leaks around doors and windows
may provide enough fresh air for combustion
and ventilation. However, in buildings of un-
usually tight construction, you must provide
additional fresh air.

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/Hr
Gas 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/Hr
Vent-free replace + _________ Btu/Hr
Total = _________ Btu/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.
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.

Note: When used as a vented heater, ap-
pliance must be installed only in a solid-fuel
burning replace with a working ue and con-
structed of noncombustible material.
For Massachusetts Residents Only: Instal-
lation of this gas log set as a vented appliance
in the Commonwealth of Massachusetts re-
quires 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 vent-
free operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply to you,
you must permanently open chimney ue
damper. You must install the damper clamp
accessory (to order, see Accessories, page
29). This will insure vented operation (see Fig-
ure 10). The damper clamp will keep damper
open. Installation instructions are included
with clamp accessory.
See charts for minimum permanent ue open-
ing you must provide. Attach damper clamp
so the minimum permanent ue opening will
be maintained at all times.

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
• approved exible gas line with gas con-
nector (if allowed by local codes) (not
provided)
* 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 re-
duce incoming gas pressure, heater regulator
damage could occur. Install external regulator
with the vent pointing down as shown in Figure
13, page 14. Pointing the vent down protects
it from freezing rain or sleet.
www.fmiproducts.com 125010-01A14
CAUTION: Use only new,
-
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.
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.

The variable control valve can be set to any
heat setting and ame height desired, by sim-
ply turning the control knob until that setting
is attained. Even the lowest setting provides
realistic ames and glowing embers from two
burners. Selecting higher settings produces
greater heat output. This results in increased
heating comfort.

CAUTION: Do not try to ad-
-
Note: Home owners generally prefer to oper-
ate their heater with the chimney damper
closed. This will put all the heat into the room.
However, there may be times you will desire
the full ames of the High heat setting but will
nd the heat output excessive. You can open
the chimney damper (if you have one) fully or
partially to release some of the heat.

7. Keep control knob pressed in for 30 sec-
onds after lighting pilot. After 30 seconds,
release control knob.
• If control knob does not pop out when
released, turn off gas supply and contact
a qualied service person or gas supplier
for repairs.
Note: If pilot goes out, repeat steps 3
through 7.
8. Push in and turn control knob counter-
clockwise to the HI position. Both
burners should light. Set control knob to

MANUAL LIGHTING
1. Follow steps 1 through 5 under Lighting
Instructions, page 18.
2. Press control knob and light pilot with
match.
3. Keep control knob pressed in for 30 sec-
onds after lighting pilot. After 30 seconds,
release control knob. Now follow step 8
under Lighting Instructions, page 18.
Check pilot ame pattern and burner ame
patterns often.
Figure 25 shows a correct pilot ame pattern.
Figure 26 shows an incorrect pilot ame pat-
tern. The incorrect pilot ame is not touching
the thermocouple. This will cause the thermo-
couple to cool. When the thermocouple cools,
the heater will shut down.
If pilot ame pattern is incorrect, as shown
in Figure 26
• turn heater off (see To Turn Off Gas to
Appliance
• see Troubleshooting, page 21
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.
Figure 27 shows correct front burner ame
pattern. Figure 28 shows incorrect front burner
ame pattern. The incorrect burner ame pat-
tern shows yellow tipping at top of blue ame.
-
If front burner ame pattern is incorrect, as
shown in Figure 28
• turn heater off (see To Turn Off Gas to
Appliance)
• see Troubleshooting, page 21

CLEANING AND MAINTENANCE
4. Check injector holder located at the end of
the burner tube again. Remove any large
particles of dust, dirt, lint or pet hair with
a soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the
injector holder.
6. In case any large clumps of dust have now
been pushed into the burner repeat steps
3 and 4.
Clean pilot assembly also. A yellow tip on the
pilot ame indicates dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about 2" from where the pilot ame comes out
of the pilot assembly (see Figure 30). With the
unit off, lightly blow air through the air inlet
hole. You may blow through a drinking straw
if compressed air is not available.

LOGS
• If you remove logs for cleaning, refer to
Installing Logs, page 16, to properly replace
logs.
• Replace log(s) if broken or chipped (dime-
sized or larger).
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame
holes should be open with yellow ame pres-
ent. 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.
WARNING: Turn off heater
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.
1. Shut off unit, including pilot. Allow unit to
cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet
holes on injector holder for dust and dirt
(see Figure 29).
3. Blow air through the ports/slots and holes
in the burner.
