Vent Free Features
The Radiance RUVS40 is an unvented gas heating
appliance tested and listed to the ANSI standard
Z21.11.2a 1997. 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 RUVS40 is not fuel convertible.
The Radiance burner controls are conveniently
located and easy to operate. As illustrated in Figure 1,
the front lip of the heater swings down to reveal the gas
valve controls and piezo pilot ignitor. Once the standing
pilot is lit, the heater can be set for either manual or
thermostatic operation using the convenient toggle
switch (Fig. 3) at the rear of the unit. A variable regulator allows 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.

WARNING
THIS HEATER MUST HAVE FRESH AIR FOR
PROPER OPERATION. IF NOT, POOR FUEL
COMBUSTION COULD RESULT. READ THE
FOLLOWING INSTRUCTIONS TO INSURE PROPER
FRESH AIR FOR THIS AND OTHER FUEL-BURNING
APPLIANCES IN YOUR HOME.
Fresh Air Requirements for
Combustion and Ventilation
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.

follow the procedure below.
Determine if You Have a Confined or
Unconfined Space
Use the following formula to determine if you have a
confined or unconfined space.

doorless passageways or ventilation grilles between
the rooms.
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 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 unconfined
space.
1. Determine the volume of space, (length x width x
height). Include adjoining rooms connected by doorless
passageways or ventilating grilles.
Example:
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'
with a volume of 1152 cubic feet. The total space
volume is 3840 cubic feet. (1728 + 960 + 1152).
The result is the maximum BTU/Hr that the space can
support.

2. Divide the volume of space by 50 cubic feet.
3840 divided by 50 = 76.8 or 76,800 BTU/Hr.

3. Add the BTU/Hr ratings of all fuel-burning appliances installed in the same space, including the
following:
Gas Water Heater Gas Furnace
Gas Fireplace Logs Unvented Gas Heater
Vented Gas Heater* Other Gas Appliances*
* Do not include Direct Vent appliances as these
utilize outside air for combustion and vent to the
outdoors.
Example:
Gas Range 55,000 BTU/Hr
Unvented Heater +33,000 BTU/Hr
Total 88,000 BTU/Hr
4. Compare the maximum BTU/Hr rating the space can
support with the total BTU/Hr used by the appliances.
Example:
76,800 BTU/Hr - max. the space can support
88,000 BTU/Hr - total used by appliances
In this example, the maximum BTU/Hr that the
space can support is less than the total used by the
appliances, the space is considered to be
space
. Additional air must be provided to meet the
Confined
requirements of the Unvented heater.
A confined space may be ventilated in two ways:
A) Open up or provide at least two ventilating grilles
to an adjoining unconfined space. Use any of the
options illustrated in Figure 4.
Each of the two grilles must provide an opening of
at least 50 square inches, with all opening dimensions
being at least 3". One grille must be located within 12"
of the ceiling; the other within 12" of the floor. (If the
total exceeds 100,000 BTU/Hr, additional grilles will be
required.)
B) Vent the room directly to the outdoors. (Provide
one square inch of opening for each 4,000 BTU/hr.
If the total BTU/Hr used by the appliances is less
than the maximum BTU/Hr the space is able to support, the room meets the Unconfined space criteria and
no further ventilation is required.
For further information on ventilation guidelines
and sizing specifications follow the National Fuel Gas
Code NFPA 54/ANSI Z223.1 Section 5.3.
