SAFETY:Accidents are always tragic, especially
because so many of them could have been prevented
with a little care and judgment. There are some basic
good practices we hope you will follow for safe use of
your gas fired room heater.
IMPORTANT: 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 and carbon monoxide
poisoning.
Early signs of carbon monoxide poisoning resembles
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 and those at high altitudes.
Begin by ensuring proper installation and servicing.
Follow the installation instructions provided with this
product. Have your heater installed by a qualified
technician. Have the installer show you where the gas
supply shut off valve is located so that you know where
to shut off the gas to the heater. If the connections are
not perfectly seated or tightened, you may have a leak
and therefore a faint gas smell.
Finding 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 Requirements
Fresh Air for Combustion and Ventilation
WARNING:
This heater must have fresh air for proper opera-
tion. If not, poor fuel combustion could result.
Read the following instructions to insure proper
fresh air for this and other fuel-burning appli-
ances in your home.
Modern construction standards have resulted in homes
that are highly energy-efficient and that allow little heat
loss. Your home needs to breathe, however, and all
fuel-burning appliances need fresh air to function
properly and safely. Exhaust fans, clothes dryers,
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.
Provide for Adequate Ventilation
Any space within a home can be classified in these
categories:
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
defined as construction where:
Walls and ceilings exposed to the outside atmosphere
have a continuous water vapor retarder with a rating of
one perm or less with openings gasketed or sealed
and;
Caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates
and floors, between wall/ceiling joints, between wall
panels, at penetrations for plumbing, electrical and gas
lines, and at other openings.
Unconfined space: An unconfined space whose
volume is not less than 50 cubic feet for each 1,000
Btu/Hr 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 consid-
ered a part of the unconfined space.
Confined space: A confined space whose volume is
less than 50 cubic feet for each 1,000 Btu/Hr of the
aggregate input rating of all appliances in that space.
WARNING: You must provide additional ventilation air
in a confined space.
For proper operation of the unit, provide fresh air
opening(s) to the room. Follow the National Fuel Code
NFPA54/ANSI Z223.1, for required size of combustion
and ventilation openings.
NOTICE: A qualified service technician should install
heater. Follow all local codes.
Gas Type
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 that the heater is
orificed for.
Items Needed for Heater Installation
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.
Locating the Heater
This heater is designed to be mounted on a wall. The
heater may also be located on the floor away from a
wall. An optional floor mounting base is required and cn
be purchased from your dealer.
WARNING: Never install the heater:
•in a bathroom,
•in a recreational vehicle,
•where curtains, furniture, clothing or other
flammable objects are less than 36” from the
front, top or sides of the heater,
•as a fireplace insert,
•in high traffic areas, or
•in windy or drafty areas.
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.

Connect to Gas Supply
Before connecting the appliance, turn of all gas appli-
ances. Close the main gas valve at the gas meter or Lp
tank. Make certain there is good ventilation where the
installation will be made. Installation should comply with
all applicable building codes and ANSI Z223.1, latest
edition. Use LP gas resistant pipe compound to seal
threaded joints.
An installer supplied, design certified gas pressure
regulator must be installed to bring the gas supply
pressure down to 14” w.c.
WARNING: Never connect an unregulated gas line
to the heater.
IMPORTANT: Check gas line pressure before connect-
ing heater to gas line. Gas line pressure must not be
higher than 14” w.c. If gas line pressure is higher,
heater gas pressure regulator damage could occur.
NOTE: The gas line connection can be made with 3/8”
black or steel pipe. Internally tinned copper tubing may
be used in certain areas. Check your local codes. Use
pipe of large enough diameter to allow proper gas
volume to heater. If pipe is too small, undue pressure
loss will occur.
CAUTION: Use pipe joint sealant that is resistant to
liquefied petroleum gases.
Install sediment trap in supply line as shown in Figure 6.
Locate sediment trap where it is within reach for
cleaning. Locate sediment trap where trapped matter is
not likely to freeze. A sediment trap prevents moisture
and contaminants from going into the heater controls. If
the sediment trap is not installed or is installed wrong,
the heater may not operate properly.
Test for gas leaks with a mild soap and water solution.
Apply water/soap solution with brush only - do not over
apply. NEVER test with an open flame.
Floor Installation
1. The heater may only be installed on a noncombus-
tible flat surface. Wall mounting screws may be used
to keep heater from side movements.
2. Measure heater mounting screws location “X” as
desired above floor. (Fig. 5)
3. Use enclosed “paper template” for proper distance
between holes. Be sure template is level. It may be
necessary to use plastic or lead anchors for plaster
wall.
4. Drill holes at marked locations using 9/64” drill bit.
5. Leave screw head out from wall far enough to
attach heater.
