Pressure Test Points
UVL-R Series: The gas control is equipped with a
captured screw-type pressure test point, therefore it
is not necessary to provide a 1/8" test point
upstream of the control.
UVL-M Series: The gas valve control is equipped
with a captured screw type inlet and manifold
pressure test point on the right side of the valve.
Odor During Operation
Neither natural gas nor propane gas give off an odor
when burned. The nature of a vent free combustion
system, however, is such that odors may

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) in
USA, installations must be in accordance with
the current ANSI Z223.1 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or
local authorities having jurisdiction for
installations at elevations above 4,500 feet
(1,370m)
occasionally be produced during heater operation
when impurities exist in the immediate area.
Cleaning solutions, paint, solvents, cigarette smoke,
candles, adhesives, new carpet or textiles, etc., all
can create fumes. These fumes may mix with
combustion air and can create odor. Such odors will
disappear over time, however, the condition can be
alleviated by opening a window or otherwise
providing additional ventilation to the area.
