PRODUCT FEATURES
OPERATION
This rebox is designed for use with approved
ANSI Z21.11.2 decorative type unvented room
heaters. (Physical size limitations apply. Refer
to minimum rebox requirements supplied
with log heater.) It requires no outside vent-
ing or chimney making installation easy and
inexpensive. When used without the blower,
the rebox requires no electricity making it
ideal for emergency backup heat.
The circulating models will accept a rotary
type fan (model BK) accessory. The blower
circulates heated air from the rebox into the
room. Use of blower is optional.
Your rebox may feature a concrete refrac-
tory brick liner. As with all concrete liners,
this liner may develop slight cracks when
exposed to heat. These cracks will not affect
the performance of the replace or vent-free
gas logs.

PLANNING
Plan where you will install the rebox. This will save
time and money later when you install the rebox.
Before installation, consider the following:
1. Where the rebox will be located. Allow for
wall and ceiling clearances (see Installation
Clearances, page 10).
AIR FOR COMbUSTION AND VENTILATION
WARNING: This heater shall

National Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International
Fuel Gas Code,-
-
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 ap-
pliances need fresh air for proper combustion
and ventilation.
Exhaust fans, reboxes, 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 page 7 through 9 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.

and
If your home meets all of the three criteria
above, you must provide additional fresh air.
See Ventilation Air From Outdoors, page 9.
If your home does not meet all of the three
criteria above, proceed to Determining Fresh-
Air Flow for Firebox Location, page 8.
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/hr (4.8 m3 per kw) of the aggregate
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/hr (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.

AIR FOR COMbUSTION AND VENTILATION

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 heater plus any adjoining rooms with
doorless passageways or ventilation grills
between the rooms.
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 22 ft. (length) x 18
ft. (width) x 8 ft. (ceiling height) = 3168 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 deter-
mine the maximum Btu/Hr the space can
support.
_____ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 3168 cu. ft. (volume of space) x
20 = 63,360 (maximum Btu/Hr the space
can support)
3. Add the Btu/Hr of all fuel burning appli-
ances in the space.
Vent-free heater ________ 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 appli-
ances. Direct-vent draws combustion
air from the outdoors and vents to the
outdoors.
Example:
Gas water heater ________ Btu/Hr
Vent-free heater +_______ Btu/Hr
Total =_______ Btu/Hr
4. Compare the maximum Btu/Hr the space
can support with the actual amount of Btu/
Hr used.
40,000
39,000
79,000
_______ Btu/Hr (maximum the space
can support)
_______ Btu/Hr (actual amount used)
Example: 63,360 Btu/Hr (maximum
the space can support)
79,000 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 9.
C. Install a lower Btu/Hr heater, if lower Btu/
Hr size makes room unconned.
If the actual Btu/Hr used is less than the
maximum Btu/Hr the space can support, the
space is an unconned space. You will need
no additional fresh air ventilation.

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.
www.fmiproducts.com 115254-01C14
INSTALLATION
Continued
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
12. Pointing the vent down protects it from
freezing rain or sleet.
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 13 or 14, depending on your model).
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.
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 Figures 13
and 14, depending on your model. 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.
