Water vapor is a by-product of gas combustion. An unvented room
heater produces approximately one ounce (30ml) of water for every
1,000 BTU's (.3KW's) of gas input per hour. .
Unvented room heaters are recommended as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
This heater shall not be installed in a conned space or unusu-
ally tight construction unless provisions are provided for adequate
combustion and ventilation air.
A conned space is an area with volume less than 50 cubic feet per
1,000 Btuh of the combined input rates of all appliances drawing
combustion air from that space. Small areas such as equipment
rooms are conned spaces. Furnaces installed in a conned space
which supply heated air to areas outside the space must draw return
air from outside the space through tightly sealed return air ducts. A
conned space must have 2 openings into the space for combus-
tion air. One opening must be within 12 inches of the ceiling and
the other must be within 12 inches of the oor. The required sizing
of these openings is determined by whether inside or outside air is
used to support combustion, the method by which the air is brought
to the space (vertical or horizontal duct) and by the total input rate
of all appliances in the space.
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 dened as construction
where:
a. 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
b. Weatherstripping 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 7.
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or
unconned space.
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 16 ft. (length) x 10 ft. (width) x 8 ft. (ceiling
height) = 1,280 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. Divide the space volume by 50 cubic feet to determine the
maximum BTU/Hr the space can support.
(volume of space) ÷ 50 cu. ft. = (maximum
BTU/Hr the space can support)
Example: 1,280 cu. ft. (volume of space) ÷ 50 cu. ft. = 25.6 or
25,600 (maximum BTU/Hr the space can support)
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application, including
ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidier may be used to
help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.

3. Add the BTU/Hr of all fuel burning appliances 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
Example: Vented gas heater 20,000 BTU/Hr
Vent-free heater + 18,000 BTU/Hr
Total = 38,000 BTU/Hr
*Do not include direct-vent gas appliances. Direct vent draws
combustion air from the outdoors and vents to the outdoors.
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:
25,600 BTU/Hr (maximum the space can support)
38,000 BTU/Hr (actual amount of BTU/Hr used)
WARNING
If the area in which the heater may be operated is smaller than
that dened as an unconned space or if the building is of
unusually tight construction, provide adequate combustion
and ventilation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1, Section 5.3 or applicable
local codes.
The space in the above example is a conned space because the
actual BTU/Hr used is more than the maximum BTU/HR the space
can support. 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 unconned 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.
C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes room
unconned.
If the actual BTU/Hr used is less than the maximum BTU/Hr the
space can support, the space is an unconned space. You will need
no additional fresh air ventilation.
WARNING
You must provide additional ventilation air in a conned space.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining unconned space. When
ventilating to an adjoining unconned 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 1). You can also remove door into adjoining room
(see option 3, Figure 1). Each ventilation grill or opening shall have
a minimum free area of one square inch per 1,000 BTU/HR of the
total input rating of the gas equipment in the conned space.
Figure 1
WARNING
Rework worksheet, adding the space of the adjoining
unconned space. The combined spaces must have enough
fresh air to supply all appliances in both spaces.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must
provide two permanent openings: one within 12" of the ceiling and
one with 12" of the oor. Connect these items directly to the outdoors
or spaces open to the outdoors. These spaces include attics and
crawl spaces. In most cases for direct communication with the
outdoors or direct communication through a vertical duct a free
area opening of one square inch per 4,000 BTU/HR of heater input
rating for each grill. If a horizontal duct is used, a grill free area or
duct opening shall have a free area opening of one square inch per
2,000 BTU/HR for each grill. Follow the National Fuel Code NFPA
54/ANSI Z223.1, Section 5.3 Air for Combustion and Ventilation for
required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or outlet air into attic
if attic has a thermostat-controlled power vent. Heated air entering
the attic will activate the power vent.

INTRODUCTION
Instructions to Installer
1. Installer must leave instruction manual with owner after
installation.
2. Installer must have owner ll out and mail warranty card supplied
with unvented room heater.
3. Installer should show owner how to start and operate unvented
room heater.
Always consult your local Building Department regarding regula-
tions, codes or ordinances which apply to the installation of an
unvented room heater.
This appliance may be installed in an aftermarket* manufactured
(mobile) home, where not prohibited by state or local codes.
*Aftermarket: Completion of sale, not for purpose of resale, from
the manufacturer.
Well Head Gas Installations
Some natural gas utilities use “well head” gas. This may affect
the Btu output of the unit and promote sooting. Units shall not be
converted to use well head gas.
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.
WARNING
Any change to this heater or its controls can be dangerous.
Improper installation or use of the heater can cause serious
injury or death from re, burns, explosion or carbon monoxide
poisoning.
Operation
This unvented replace requires no outside venting. State and local
codes in some areas prohibit the use of unvented replace.
Millivolt Controls
The valve regulator controls the burner pressure which should be
checked at the pressure test point. Turn captured screw counter
clockwise 2 or 3 turns and then place tubing to pressure gauge over
test point (Use test point “A” closest to control knob). After taking
pressure reading, be sure and turn captured screw clockwise rmly
to re-seal. Do not over torque. Check for gas leaks.
Millivolt System
When you ignite the pilot, the thermocouple produces millivolts
(electrical current) which energizes the magnet in the gas valve. After
30 seconds to 1 minute time period you can release the gas control
knob and the pilot will stay ON. Allow your pilot ame to operate
an additional one to two minutes before you turn the gas control
knob from the PILOT position to the ON position. This time period
allows the millivolts (electrical current) to build-up to a sufcient
level allowing the gas control to operate properly.
WARNING
This appliance is equipped for (Natural Gas or Propane) Gas.
Field conversion is not permitted.
General Information
This series is design certied in accordance with American National

A manual main gas shut-off should be located in the vicinity of the
unit. Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liqueed petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed ame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the gas
inlet. This should consist of a vertical length of pipe tee connected
into the gas line that is capped on the bottom in which condensation
and foreign particles may collect.
The use of the following gas connectors is recommended:
— ANS Z21.24Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANS Z21.45Assembled FlexibleAppliance Connectors of Other
Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The Commonwealth of Massachusetts requires
that a exible appliance connector cannot exceed three feet in length.

Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must
be placed immediately upstream of the gas supply connection
to the appliance.
2. The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shut-off valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa).
Figure 3
Attention! If one of the above procedures results in pressures in
excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve,
it will result in a hazardous condition.
Checking Manifold Pressure
Millivolt and Intermittent Models Natural Gas will have a manifold
pressure of approximately 3.5" w.c. (.871kPa) for maximum input or
1.7" w.c. (.423kPa) for minimum input at the pressure regulator outlet
with the inlet pressure to the pressure regulator from a minimum
of 5.0" w.c. (1.120kPa) for the purpose of input adjustment to a
maximum of 10.5" w.c. (2.614kPa).
Hydraulic Thermostat Models Natural Gas will have a manifold
pressure of approximately 6.0" w.c. (1.49kPa) at the pressure
regulator outlet with the inlet pressure to the pressure regulator
from a minimum of 7.0" w.c. (1.74kPa) for the purpose of input
adjustment to a maximum of 10.5" w.c. (2.615kPa).
Millivolt and Intermittent Models Propane Gas will have a manifold
pressure approximately 10.0"w.c. (2.49kPa) for maximum input or
6.3"w.c. (1.568kPa) for minimum input at the pressure regulator outlet
with the inlet pressure to the pressure regulator from a minimum
of 11.0"w.c. (2.739kPa) for the purpose of input adjustment to a
maximum of 13.0"w.c. (3.237kPa).
Hydraulic Thermostat Models Propane Gas will have a manifold
pressure approximately 10.0"w.c. (2.49kPa) at the pressure regulator
outlet with the inlet pressure to the pressure regulator from a minimum
of 11.0"w.c. (2.739kPa) for the purpose of input adjustment to a
maximum of 13.0"w.c. (3.237kPa).

Provided with the log set is a small bag of glowing embers (rock
wool) to be placed between logs on the at metal surface of the
burner.
Placement of the embers (rock wool) is very individual and light
coverage of the areas indicated will provide your best effects. We
recommend separation of the rock wool by hand and make your
coverage as light and uffy as possible.
Place just enough embers (rock wool) on the burner to obtain the
glow and a gold yellow ame.
A thin layer of rock wool should be placed under open space
between the right and left middle logs.
Do not place rock wool over large ports in rear portion of burner.
Do not place rock wool in the area of the pilot assembly.
Replacement of loose material (glowing embers) must be purchased
from Empire Comfort Systems, Inc. Application of excess loose
material (glowing embers) may adversely affect performance of
the heater.
WARNING
All previously applied loose material must be removed prior to
reapplication.
Refer to Parts List, Pages 33-34 to order loose material (rock wool).
REPLACEMENT LOOSE MATERIAL (GLOWING EMBERS)
15998 Supplied Rock Wool
PE-20-1 Optional Platinum Bright Embers Kit
NOTICE: A single layer of embers is to be used when applying
Platinum Bright Embers (alone or in combination with production
embers) to the burner.
Flames from the pilot (rear right back side of the pan burner) as
well as the main ame should be visually checked as the log set
is installed.
In normal operation at full rate after 10 to 15 minutes, the ame
appearance should be sets of yellow ames.
NOTICE: all ames will be random by design, ame height will go
up and down.
Glowing embers (rock wool) can cover the pan burner in between
the front and middle logs, but very little is necessary to cover this
area. Excess ember material causes the yellow ame to become
orange and stringy. Apply just enough to obtain slow glow and a
gold, yellow ame.
Avoid any drafts that alter burner ame patterns. Do not allow fans to
blow directly into replace. Do not place a blower inside the burner
area of the rebox. Ceiling fans may create drafts that alter ame
patterns. Sooting and improper burning will result.
During manufacturing, fabricating and shipping, various components
of this appliance are treated with certain oils, lms or bonding agents.
These chemicals are not harmful, but may produce smoke and
smells as they burn off during the initial operation of the appliance,
possibly causing headaches or eye or lung irritation. This is a normal
and temporary occurrence.
The initial break-in operation should last 2-3 hours with the burner
at the highest setting. Provide maximum ventilation by opening
windows or doors to allow odors to dissipate. Any odors remaining
after this initial break-in will be slight and will disappear with
continued use.
This appliance must not be used with glass doors in the closed
position. This can lead to pilot outages and severe sooting outside
the replace.

PILOT FLAME CHARACTERISTICS
Figures 13, 14 and 15 show a correct pilot ame pattern. The
correct ame will be blue and will extend beyond the thermocouple.
The ame will surround the thermocouple just below the tip. A slight
yellow ame may occur where the pilot ame and main burner ame
meet. Figures 16, 17 and 18 show 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.
