Vermont Castings Radiance
General Information
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 regula-
tor 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.
Quick Installation
Your Radiance Vent Free heater is shipped completely
assembled and ready for installation. You must,
however, locate the heater in accordance with the
specifications detailed in the next section of this
manual. Connection to the gas supply must be
made only by a qualified gas technician and only
after verification that the minimum combustion air
and ventilation requirements have been met.
Optional Fan Kit #2767 /FK26
This accessory will help distribute heated air from
within the firebox out into the room. The fan is con-
trolled by a snapstat that turns power on and off as the
firebox temperature rises above and falls below a
preset temperature. A rheostat provides for variable
fan speeds up to 160 cfm.
Optional
Glass / Catalyst Kit RGDCFK
The glass panel replaces the standard screen. The
catalytic combustor installs easily into the upper
manifold above the firebox. Ask your dealer for details.
