WATER VAPOR: A BY-PRODUCT OF VENT-FREE ROOM HEATERS
Water vapor is a by-product of gas combustion. A vent-
free room heater produces approximately one (1) ounce
(30ml) of water for every 1,000 BTU's (.3KW's) of gas
input per hour.
Unvented room heaters are intended for 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.
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.
2. If high humidity is experienced, a dehumidifier
may be used to help lower the water vapor content
of the air.
3. Do not use a vent-free room heater as the primary
heat source.
A IMPORTANT: Vent-free heaters add mois-
ture 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 Combus-
tion and Ventilation, pages 5 and 6.
AIR FOR COMBUSTION
AND VENTILATION
Á 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.
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.
LengthXWidthxHeight=
to the total volume of 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
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 (6x10 kg
per pa-sec-m? 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
Determining Fresh-Air Flow for
Heater Location, page 5.
cu.ft. (volume of space)
Confined and
Unconfined Space
The National Fuel Gas Code ANSI
2223.1 defines a confined space as
a space whose volume is less than
50 cubic feet per 1,000 Btu per hour
(4.8 m* per kw) of the aggregate
input 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*
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 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 air.
* Adjoining rooms are communi-
cating only if there are doorless
passageways or ventilation grills
between them.
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 (lengthxwidthxheight).
Example: Space size20ft. (length)x16ft.( width)x8ft. (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
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)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater Btu/Hr
Gas water heater* Btu/Hr Example:
Gas fumace Btu/Hr Gas water heater 40,000 Btu/Hr
Vented gas heater Btu/Hr Vent free heater + 18,000 Btu/Hr
Gas Fireplace logs Btu/Hr Total - 58,000 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.
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.
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 codes.

*A CSA/AGA design-certified equipment shutoff valve with 1/8” NPT tap
is an acceptable alternative to test gauge connection. Purchase the
optional CSA/AGA design-certified equipment shutoff valve from
your dealer.
In the state of Massachusetts the gas
cock must be a T handle type. The
state of Massachusetts requires that
a flexible appliance connector cannot
exceed three feet in length .
IMPORTANT: Install an 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 threads. This will prevent
excess sealant from going into
pipe. Excess sealant in pipe could
result in clogged heater valves.
Install sediment trap in supply line
as shown in Figure 12. Locate
sediment trap where it is within
reach for cleaning. 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.
CHECKING GAS

air, or small, soft bristled brush
to clean.
CLEANING BURNER AND PILOT
AIR INLET HOLE
We recommend that you clean the
unit every 2,500 hours of operation
or every three months. We also
recommend that you keep the burner
tube and pilot assembly clean and
free of dust and dirt.
14
To clean these parts we recommend
using compressed air no greater
than 30 PSI. 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 direc-
tions on the can. If you don’t follow
directions on the can, you could dam-
age the pilot assembly.
1. Shut off the unit, including the
pilot. Allow the unit to cool for
at least thirty minutes.
Inspect burner, pilot for dust
and dirt.
3. Blow air through the ports/slots
and holes in the burner.
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.

LIMITED WARRANTY HEARTHRITE VENT-FREE-FIREPLACE Gas 374 ce Meatens
HearthRite warrants this product to be free from defects in materials, components except for electrical components
and limited labor for (3) three year and electrical components for (1) year from the date of first purchase, provided
that the product has been properly installed, operated and maintained in accordance with all applicable instructions.
To make certain under this warranty, the Bill of Sale or cancelled check must be presented.
This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to
restore this heater to proper operating condition and an allowance for labor when provided by a HearthRite
Authorized Service Center. Warranty part(s) MUST be obtained through authorized dealers of this product and/or
HearthRite who will provide original factory replacement parts. Failure to use original factory replacement parts voids
this warranty. The heater MUST be installed by a qualified installer in accordance with all local codes and instructions
furnished with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear or parts that
fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper
installation.
Some States do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental
or consequential damages, so the above limitation on implied warranties, or exclusion or limitation on damages may
not apply to you.
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state. For
information about this warranty, please write to:
