WARNING
This appliance must not be vented with any other applianc-
es, even if that appliance is of the condensing type. Com-
mon venting can result in severe corrosion of other appli-
ances or their venting and can allow combustion gases to
escape through such appliances or vents. Do not vent the
wall furnace into a replace chimney or building chase. The
ue exhaust pipe must be vented outside.
WARNING
Upon completion of the installation, carefully inspect the en-
tire ue system to ensure it is properly sealed. DO NOT use
any vent material other than what is specied in this manual.
Leaks in the ue system can result in serious personal injury
or death due to exposure of ue products, including carbon
monoxide.
The UltraSaver is classied as a “Category IV” appliance, which
requires special venting materials and installation procedures.
Installations can be Conventional (one-pipe) and Direct Vent
(two-pipe). Venting must be completed with 1-1/2 or 2 inch diam-
eter pipe. In selecting a location for installation, it is necessary to
provide adequate clearances for servicing and proper installation.
All vent and combustion air pipes and ttings must be Schedule
40 PVC and meet the ANSI/ASTM Standard D1785. Cement
must conform to ASTM Standard D2564. Empire approved poly
pipe with gasketed joints may also be used. Contact your Empire
dealer for availability. The use of vent tubes not approved by the
manufacturer may result in unsatisfactory performance.
The ue exhaust pipe and inlet air pipe should be located between
wall studs. If an existing unit is being replaced, the ue exhaust
and inlet pipes may be run continuously through the existing ue
pipe or wall opening. See page 15 for special termination kits. The
required opening for venting is 1-7/8 inch in diameter for 1-1/2 inch
pipe, and 2-3/8 inch diameter for two inch pipe.
The ue outlet must be at least twelve inches from any opening
which ue gases could enter the building. See Figure 36. The ue
outlet must be a minimum distance of three feet from any pressure
regulator.
The bottom of the exhaust vent terminal and the air intake must
be located at least twelve inches above grade or the maximum
snow level.
The pipe must be supported every three feet on horizontal runs
and every 10 feet on vertical runs. All horizontal runs must be
pitched ¼ inch per foot towards the wall furnace.
Notice: If the vent run dips or sags, condensation may become
trapped and cause the wall furnace to not operate properly.
The minimum vent length protruding from outside the wall is ten
inches. For two-pipe installation, a minimum distance of ve inch-
es from pipe centers and maximum distance of 24 inches must be
maintained between the pipes. See Page 30.
Maximum Vent Length is 50 feet. Each 90° elbow used in the
vent system will be the equivalent to three feet, and each 45°
elbow is equivalent to 1.5 feet, which should be added to the
overall vent length. The vent terminal does not contribute to the
overall vent length measurement.
Notice: If vent length requirements are not followed, the wall
furnace will not operate properly.
Vent Freezing Protection
When the vent pipe is exposed to temperatures below freezing
(i.e. when it passes through unheated spaces, chimneys, etc.) The
pipe must be insulated with 1/2 inch thick sponge rubber insula-
tion, Armaex-type insulation or equivalent (Ameraex is a regis-
tered trademark of Amaracell). Insulating pipe is important to avoid
condensate icing. See Figure 37.
Figure 37
The minimum ue length off the wall is 10”.
The bottom of the exhaust vent terminal and the air intake shall
be located at least 12 inches above grade or expected snow level.
WARNING
The nearest point of the vent cap should be a minimum
horizontal distant of six feet (1.83m) from any pressure
regulator. In case of regulator malfunction, the six feet (1.83m)
distance will reduce the chance of gas entering the vent cap.
