SAFETY INFORMATION
Please read this manual
before installing and using
the heater.
WARNING:
If the infor
mation in
this manual is not followed
exactly, a fire or explosion may
result causing property damage,
personal injury or loss of life.
• Do not store or use gasoline or other
flammable vapors and liquids in the
vicinity of this or any other appliance.
• WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch;
do not use any phone in your
building.
• Immediately call your gas supplier
from a neighbour’s phone. Follow the
gas supplier's instructions.
• If you cannot reach your gas
supplier, call the fire department.
• Installation and service must be
performed by a qualified installer,
service agency or the gas supplier.
Installer: Leave this manual
with the heater.
Consumer: Retain this

the room in which it is installed.
Provisions for adequate
combustion and ventilation air
must be pr
ovided. Refer to the

General Information
SAFETY: Accidents are always tragic especially because so
many of them could have been prevented with a little care and
attention. These are some basic good practices we hope you
will follow for safe use of your gas fired room heater.
IMPOR
TANT: Read this user's manual carefully and
completely before trying to assemble, operate or service
this heater. Improper use of this heater can cause serious
injury or death from burns, fire, explosion, electrical shock
(fan models) or carbon monoxide poisoning.
Early signs of carbon monoxide poisoning resemble the flu
with headaches, dizziness or nausea. If you have these signs,
the heater may not be working properly. Get fresh air at once!
Have heater serviced. Some people are more affected by
carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia, those
under the influence of alcohol or those at high altitude.
Begin by ensuring proper installation and servicing. Ensure
that your qualified technician who installs this heater follows
the installa
tion instructions provided with this product.
Ha
ve
the installer show you where the gas supply shut off valve is
loca
ted so tha
t you kno
w where to shut off the gas to the
hea
ter
.
If the connections are not perfectly sealed or
tightened, you may have a leak and therefore a faint gas
smell.
F
inding a leak is NOT a do-it-yourself procedure.
Some leaks can only be found with the main burner gas on
and this must be done by a qualified technician.

Installation
• This heater shall not be installed in a confined space or
unusually tight construction unless provisions are provided
for adequate combustion and ventilation air.
•
This heater must have fresh air for proper operation. If not,
poor fuel combustion could result. Read the following
instructions to insure proper fresh air for this and other fuel
burning appliances in your home.
Modern construction standards have resulted in homes that
are highly energy efficient and that allow little heat loss.
However, your home needs to breathe and all fuel burning
appliances need fresh air to function properly and safely.
Exhaust fans, clothes dryer, fireplaces and other fuel burning
appliances all use the air inside the building. If the available
fresh air supply is insufficient to meet the demands of these
appliances, problems can result.
Confined Space:
The National fuel Gas Code, ANSI Z223.1 / NFPA 54 defines a
confined space as a space whose volume is less than 50
cubic feet per 1000 BTU per hour (4.8 m3 per kw) of the
aggregate input rating of all appliances installed in that space.
Unconfined Space:
An unconfined space is defined in the same standards as a
space whose volume is not less than 50 cubic feet per 1000
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 unconfined space.
Example:
10,000 BTU Legacy heater should only be installed in a room
whose volume is more than 500 cubic feet. A room that is 8'
x 8' x 8' (512 cubic feet) would be acceptable for a Legacy
10,000 BTU/hour heater.
If an additional fuel fired appliance is installed in the same
room,
the input ra
ting of tha
t a
ppliance should be added to
tha
t of the Legac
y hea
ter to determine the minimum sized
room that should be serviced by both appliances.
Unusually tight construction is defined as construction
where:
a) Walls and ceilings exposed to the outside atmosphere have a
continuous wa
ter va
pour retarder with a rating of 1 perm (6 x
10-11 kg per pa-sec-m2) or less with openings gasketed or
sealed;
b)
Weather stripping has been added on openable windows and
doors; and
c) Caulking or sealants are applied to areas such as joints
around windo
w and door frames, between sole plates and
floors,
between wall-ceiling joints,
between wall panels,
a
t
penetrations for plumbing, electrical and gas lines and at
other openings.
PROVIDE ADEQUATE COMBUSTION
AND VENTILATION AIR
WARNING: If the area in which the heater may be operated is
smaller that that defined as an unconfined space or if the
building is of unusually tight construction, provide adequate
combustion and ventila
tion air by one of the methods
described in the National fuel Gas code, ANSI Z223.1 / NFPA
54,
Section 5.3 or applicable local codes.
Verify the type of gas supply to be used, either natural gas or
LP (Propane), and make sure the marking on the appliance
rating plate agrees with that of the supply gas. The rating plate
is located on the side of the heater, which indicates the type of
gas the heater is manufactured for.
WARNING: This appliance is only for use with the type of gas
indicated on the rating plate.
This appliance is not convertible for use with other gases.
Before installing the heater, make sure you have these items:
• Gas piping (check local codes)
• Test gauge connection
• Sealant (resistant to LP gases) - approved thread
compound
• Manual shut-off valve*
• Sediment trap - where required
• Ground joint union
• Tee joint and pipe wrench
*An installer supplied design-certified manual shut-off valve
with 1/8 NPT tap connection.

Use pa
per templa
te supplied to mark loca
tion of mounting holes.
Be sure templa
te is level.
NOTE: Wall anchors and mounting screws are in hardware
package provided with heater.
1. Install mounting screws on wall as shown in Figure 3. Use
enclosed paper template for proper location of holes. Be
sure template is level. It may be necessary to use plastic or
lead anchors for plaster walls.
2. Drill holes at marked location using 9/64” drill bit.
Insert mounting screws.
3. Leave screw head out from wall far enough to attach
heater.
• Due to high tempera
tures, the appliance should be located out
of traffic and away from furniture and draperies. Keep flammable objects more than 36” from the front and top of the
heaters and more than 10” from the sides of the heater.
• Provide adequate clearances for accessibility for purposes of
ser
vicing the heater.
• Maintain adequate clearances around the air openings to
allow for proper and safe operation of the heater.
• WARNING: Do not allow fans to blow directly into the heater.
Avoid any drafts that alter the burner flame patterns.
This heater is designed to be mounted on a wall or on the floor.
WARNING: Never install the heater;
• in a bathroom*
• in a recreational vehicle
• where curtains, furniture, clothing or other flammable are
less than 36” from the front, top or sides of the heater
• as a fireplace insert
• in high traffic areas
• in windy or drafty areas
*Models RMC-L106NG or LP Permitted for bathroom installation.
WARNING: Vent-free heaters add moisture to the air. Although
this is beneficial, installing heater in rooms without enough
ventilation may cause mildew formation from too much
moisture content. See National Fuel Code for Fresh Air for
Combustion and Ventilation.
This appliance may be installed in an aftermarket, permanently
located manufactured (mobile) home, were not prohibited by
state or local codes.
Caution: If you install the heater in a home garage:
• Heater must be at least 18” above floor
• Locate heater where moving vehicle will not hit it.
• Install to
ANSI Z223.2 / NFPA 54 using fixed gas supply piping.
