UVHB10 Vent-Free Heaters
20004232
Description
The UVHB10 vent-free heater is designed to be in-
stalled into an FPS1212NC, FPS1214W or FPS1213N
(corner) mantel cabinet only. It may not be installed in
any other manner.
The UVHB10 is available in Natural or Propane gas,
equipped with an oxygen depletion sensor with a
standing pilot.
Minimum Clearances
Minimum clearance to combustibles are maintained
when the UVHB10 is installed into the FPS1212NC,
FPS1214W or FPS1213N mantel cabinets. Top of unit
to ceiling minimum 42 inches.
Gas Supply Pressures
This heater must be isolated from the gas supply piping
system by closing its individual manual shut-off valve
during any pressure equal to or less than 1/2 psig (3.45
kPa).
The heater and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.45 kPa).

Planning
Planning the installation is an important first step: it will
save time and money later in the actual installation. In
planning the installation, consider:
1. Where the heater will be located.
2. All components needed to complete the
project.
High Elevations
Input ratings are shown in BTU per hour and are
certified without deration from elevations up to 4,500
feet (1,370m) above sea level.
Nuisance outages may occur at altitudes above 4,500
feet (1,370m) if dirt, dust, lint and/or cobwebs are
allowed to accumulate on burner and/or ODS pilot.
Monthly inspection and cleaning is recommended for
altitudes above 4,500 feet (1,370m)
For elevations above 4,500 feet (1,370m), installa-
tions must be in accordance with the current ANSI
Z223.1 and/or local codes having jurisdiction.
The State of California requires the following warning:
WARNING: Combustion by-products
produced contain crbon monoxide, a
chemical known to the State of Califor-
nia to cause cancer and birth defects (or
other reproductive harm).
