UNPACKING
1. Remove heater from carton.
2. Remove all protective packaging applied to
State of Massachusetts : The installation must be made by a licensed plumber or gas fitter in the Commonwealth of Massachusetts. Sellers of unvented propane or natural gas-fired supplemental room heaters shall provide to each purchaser a copy of 527 CMR30 upon sale of the unit. In the State of Massachusetts, unvented propane and natural gas-fired space heaters shall be pro­hibited in bedrooms and bathrooms.
Water vapor is a by-product of gas combustion. An vent­free room heater products approximately one (1) ounce (30ml) of water for every 1,000 BTUs (.3KWs) of gas input per hour. Vent-free room heaters are recommended as supplemental heat (a room) rather than a primary heat source (an entire house) . In most supplemental heat application, the water vapor does not create a problem. In most applications, the water vapor enhances the low humidity atmosphere experience during cold weather. 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 and ventilation air.
WATER VAPOR: A BY-PRODUCT OF VENT-FREE ROOM HEATERS
IMPORTANT: Vent-free heaters add moisture to
the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form from too much moisture. See Fresh Air for Combustion and Ventilation, pages 5 and 6.

PROVIDING ADEQUATE VENTILATION
The following are excerpts from
National Fuel Gas Code. NFPA 54/
ANSI Z223.1, Section 5.3. Air for
Combustion and Ventilation. All
spaces in homes fall into one of
the three following ventilation
classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through
6 will help you classify your space
and provide adequate ventilation.
Confined and Unconfined Space
The National Fuel Gas Code ANSI
Z223.1 defines a confined space as
a space whose volume is less than
50 cubic feet per 1,000 Btu per hour
(4.8 m3 per kw) of the aggregate in-
put rating of all appliances in-
stalled in that space and an uncon-
fined space as a space whose
volume is not less than 50 cubic
feet per 1,000 Btu per hour (4.8 m
3
per kw) of the aggregate input rat-
ing 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 uncon-
fined space.
This heater shall not be installed
in a confined space or unusually
tight construction unless provisions
are provided for adequate combus-
tion and ventilation ai r.
*
Adjoining rooms are communicat-
ing only if there are doorless pas-
sageways or ventilation grills be-
tween them.
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:
a. Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm (6×10
-11
kg per pa-sec-m2) or less with openings gasketed or sealed and b. Weather stripping 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 floors, 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 6.
If your home does not meet all of the three criteria above, see Deter-
mining Fresh-Air Flow for Heater Location, page 5.
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if you have a Confined or Unconfined Space*
Use this worksheet to determine if you have a confined or unconfined 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×width×height). Length×Width×Height= cu.ft. (volume of space) Example: Space size20ft. (length)×16ft.( width)×8ft. (ceiling height)=2560cu. 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: 2560 cu. ft. (volume of space)÷50 cu.ft.=51.2 or 51.200(maximum Btu/Hr the space can support)
AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
not be installed in a confined
space or unusually tight con-
struction unless provisions are
provided for adequate combus-
tion and ventilation air. Read the
following instructions to insure
proper fresh air for this and
other fuel-burning appliances in
your home.
Page 6

Rework worksheet, adding the space of the adjoining uncon­fined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.
Ventilation Air From Inside Building
This fresh air would come from an adjoining unconfined space. When ventilating to an adjoin­ing unconfined space, you must provide two per­manent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas
Code NFPA 54/ANSI Z223.1. Section 5.3, Air for Com­bustion and Ventilation for required size of ventila-
tion grills or ducts.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.
Example: Gas water heater 40,000 Btu/Hr Vent free heater + 18,000 Btu/Hr Total = 58,000 Btu/Hr
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 Fireplace 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.
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)
58,000 Btu/Hr(actual amount of Btu/Hr used) The space in the above example is a confined 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 unconfined 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 unconfined.
Figure 2 -Ventilation Air from Inside Building
NOTE: If the area in which the heater may be operated is smaller than that defined as an unconfined 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
Figure 3 -Ventilation Air from Outdoors
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 within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Fol­low the National Fuel Gas 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.

Clean the pilot assembly also. A
yellow tip on the pilot flame indi-
cates dust and dirt in the pilot
assembly. There is a small pilot air
inlet hole about two inches from
where the pilot flame comes out of
the pilot assembly (see Figure 22).
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.

the primary air opening(s) of the
burner(s) clean may result in soot-
ing and property damage.
CAUTION: Label all wires
prior to disconnection when servic-
ing controls.Wiring errors can
cause improper and dangerous
operation. Verify proper operation
after servicing.
To clean these parts we recom-
mend using compressed air no
greater than 30 PSl.
Your local computer store, hardware
store, or home center may carry
compressed air in a can. You can
use a vacuum cleaner in the blow
position. If using compressed air in
a can, please follow the directions
on the can. If you dont follow direc-
tions on the can, you could damage
the pilot assembly.
