Vermont Castings Radiance Vent-Free Gas Heater

20004555

The Radiance RUVSOD, Model Nos. 3370 thru 3379,
is an unvented gas heating appliance tested and listed
to the ANSI standard Z21.11.2-2000. This appliance is
specifically configured to burn either Natural Gas or
Propane fuel, as indicated on the metal rating plate
attached to the rear shroud. The Radiance RUVSOD is
not fuel convertible.

The RUVSOD is shipped fully assembled with the
exception of the log set. The log set is assembled
during installation.

The RUVSOD is equipped with a Honeywell control
valve that allows thermostatic control, on/off switch or a
remote switch (not supplied).

The RUVSOD model incorporates variable regulators
that allow you to adjust burner heat output between
HIGH, (35,000 BTU), and LOW, (26,000 BTU). See the
Operation Section for details.

A push button Piezo ignitor is used to light the standing
pilot.  The pilot incorporates an Oxygen Depletion
System (ODS/pilot) which will shut off gas flow to the
burner in the event that sufficient fresh air becomes
unavailable for continued safe operation.

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 within it require fresh air in
order 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 is insufficient to meet the demands
of these appliances, problems can result.

The Radiance Unvented heater has specific fresh air
requirements.  

air requirements will be met within the space where
the appliance will be installed. The following informa-
tion will help you insure that adequate fresh air is
available for the heater to function properly.

Any space within a home can be classified in the
following categories:

1)  Unusually Tight Construction
2)  Confined Space
3)  Unconfined Space

First, determine which classification defines the
intended space.

You must provide additional fresh air if the space falls
into this classification. 

Unusually Tight Construction is

defined as construction wherein:
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.  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 supplemental fresh air for the appliance
from outside the home as detailed on page 7, B.
If your home does not meet the above criteria, follow
the procedure below.

Use the following formula to determine if you have a
confined or unconfined space.

Space is defined as the room in which you will install
the heater plus any adjoining rooms with doorless
passageways or ventilation grilles between the rooms.

The National Fuel Gas Code 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
input rating of all appliances installed in that space and
an unconfined space as a space whose volume is not
less than 50 cubic feet per 1,000 BTU per hour, (4.8
m3 per kw), of the aggregate input rating of all appli-
ances 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.
1.  Determine the volume of space, (length x width x
height)

. Include adjoining rooms connected by doorless

passageways or ventilating grilles.
Example: 

A room that is 18' x 12' x 8' has a volume of 1728 cubic
feet, ( length x width x height). An adjoining open
kitchen that is 10' x 12' x 8' has a volume of 960 cubic
feet. An adjoining open dining room is 12' x 12' x 8'
