SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a ammable gas which can cause res
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precautions
which can protect both you and your family from an accident.
Read them carefully now, then review them point by point with
the members of your household. Someday when there may not
be a minute to lose, everyone’s safety will depend on knowing
exactly what to do. If, after reading the following information,
you feel you still need more information, please contact your
gas supplier.
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas
because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
• Do not operate electric switches, light matches, use your phone.
Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such as
basements. When you have reason to suspect a gas leak, keep
out of basements and other low areas. Stay out until reghters
declare them to be safe.
• Use your neighbor’s phone and call a trained LP-Gas service
person and the re department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and reghters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell
the odor of the chemical put into the gas. You must nd out if
you can smell the odorant in propane. Smoking can decrease
your ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors in
the area mask the gas odor. People may not smell the gas odor or
their minds are on something else. Thinking about smelling a gas
odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can lter the odorant. Odorants in
LP-Gas also are subject to oxidation. This fading can occur if there
is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That will
take some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a “Scratch and Sniff” pamphlet. Use it to
nd out what the propane odor smells like. If you suspect that
your LP-Gas has a weak or abnormal odor, call your LP-Gas
Dealer.
• If you are not qualied, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualied, consciously think about the odor of LP-Gas
prior to and while lighting pilot lights or performing service or
making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the odor
if there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
reinstalled old tanks, if they are lled and allowed to set too
long before relling. Cylinders and tanks which have been out
of service for a time may develop internal rust which will cause
odor fade. If such conditions are suspected to exist, a periodic
sniff test of the gas is advisable. If you have any question
about the gas odor, call your LP-gas dealer. A periodic
sniff test of the LP-gas is a good safety measure under
any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete “gas out,” (the container is under
no vapor pressure), turn the tank valve off immediately. If the
container valve is left on, the container may draw in some air
through openings such as pilot light orices. If this occurs, some
new internal rusting could occur. If the valve is left open, then
treat the container as a new tank. Always be sure your container is under vapor pressure by turning it off at the container
before it goes completely empty or having it relled before it is
completely empty.

Locating Wall Opening
Locate wall studs and move the wall furnace into position. The shroud
has many holes and can be mounted into 16 or 24 on centers studs.
A series of holes across the top of the rear shroud corresponds to
the mounting holes to aide in aligning the mounting holes with the
wall studs. When mounted directly on the oor, plastic anchors can
be used. Ensure that the vent and gas line openings will be located
between wall studs. Ensure the wall furnace is level, adjust legs on
the bottom of the unit if necessary. See Figure 29.
Move the wall furnace away from the wall and remove the rear
shroud from the wall furnace. Remove four 10 x 1/2” hex-head
screws and set aside. Determine if using a direct vent, single ue
venting system. Place the rear shroud against the wall and mark
the vent and gas openings. For single ue installations, mark only
the left hole (as shown in Figure 31). For direct-vent installations,
mark the left and right holes. See Figure 31. The wall opening
required for intake and exhaust pipes is 2-3/8” in diameter within
the circles made above. If the wall furnace is to be wall mounted
above oor level, install per the instructions included with the wall
shroud kit listed on page 15.
Figure 29
Use masking or painter’s tape to mark the location of the two top
corners of the rear shroud against the wall. See Figure 30.

Insert the blue intake connector gasket into the inlet air opening
in the rear shroud. See Figure 33.
Installing Rear Shroud
After cutting the opening for the vent and gas line, place the shroud
back into position against the wall and secure in place. The shroud
should be mounted to the wall studs, if possible, using the four 10
x 1-1/2” hex-head screws provided. Two screws in top holes and
two screws in bottom holes. See Figure 34.
Figure 34
If installing the wall furnace on the oor, the rear shroud may be
anchored solidly to the wall using the four plastic anchors (not
provided) and four 10 x 1-1/2” (38mm) hex-head screws (provided).
Figure 33
WARNING
DO NOT use plastic anchors if installing the wall furnace off
of the oor. The wall furnace must be secured to the studs;
it may fall causing damage possible harm. Wall furnaces
installed on the oor may be secured to the wall may use
plastic anchors.

WALL FURNACE INSTALLATION
GAS SUPPLY
All gas piping must be installed in compliance with local codes and
utility regulations. In the absence of local codes the installation
must comply with NFCG NFPA 54/ANSI Z223.1.
Notice: Never use plastic pipe. Check to conrm whether your
local codes allow copper tubing or galvanized.
Where permitted, exible gas connectors must be certied to the
following standards:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tub-
ing and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority having jurisdiction. The state of Massachusetts requires that a
exible appliance connector cannot exceed three feet in length.
A drip leg should be installed in the vertical gas supply pipe run to
the wall furnace.
Manual Shut-off Valve
Some local regulations require the installation of a manual shut-off
valve and ground joint union external to the appliance. The shutoff
should be accessible for service and/or emergency use. Consult the
local utility or gas supplier for additional requirements regarding the
placement of the manual shut off valve. Compounds used on
threaded joints of gas piping shall be resistant to the action of liq-
ueed petroleum gases.
Leak Testing
WARNING - FIRE OR EXPLOSION HAZARD
Never test for leaks with an open ame. Check all connections using a commercially available soap solution. A re or
explosion may result causing property damage, personal
injury or loss of life. Failure to follow the safety warnings
exactly could result in serious injury, death or property
damage.
After gas piping to the wall furnace is complete, all connections
must be tested for gas leaks. This includes pipe connections at
the main gas valve, emergency shutoff valve and exible gas connectors (if applicable). The soap and water solution can be applied
on each joint or union using a small paintbrush. If any bubbling is
observed, the connection is not sealed adequately and must be
retightened. Repeat the tightening and soap check process until
the bubbling ceases.
2.
The appliance and its individual shutoff 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. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig.

WALL FURNACE INSTALLATION
VENTING
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 38. 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 inches from pipe centers and maximum distance of 24 inches must be
maintained between the pipes. See Page 31.
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 insulation, Armaex-type insulation or equivalent (Ameraex is a registered trademark of Amaracell). Insulating pipe is important to avoid
condensate icing. See Figure 39.
WARNING
The nearest point of the vent cap should be a minimum
horizontal distant of three feet (0.91m) from any pressure
regulator. In case of regulator malfunction, the three feet
(0.91m) distance will reduce the chance of gas entering the
vent cap.
Notice: Clean all debris from the inside of the ue pipe prior
to applying the glue and nal assembly of the pipe. Since the
condensate is designed to ow back to the appliance this debris
will be carried to the condensate trap resulting in a clog. An “A2”
error will appear on the display panel if this happens. The clog,
and the work required to x it, can be easily prevented by pulling
a wet cloth through the pipe prior to applying the glue and nal
assembly.
Install Vent Termination and Piping
The UltraSaver may be installed with up to 50’ equivalent length
venting.
Notice: For each 45° elbow installed in the run, the length
of the run MUST be reduced by 1.5 feet (45 cm). Reduce the
length of the run three feet (91.4 cm) for every 90° elbow. The
vent terminal elbow does not contribute to the overall vent
length measurement.
See pages 29 through 32 for vent termination and vent run examples and requirements.
This unit is vented directly out the back using 1-1/2” or 2” PVC
pipe. See Figure 38 for exterior vent hole location.
If 1-1/2” pipe is used, it must be enlarged to 2” pipe prior to exiting the wall into the shroud.
If venting out the back through the wall is not possible (such as
in a basement) the vent pipes may be run in front of the wall (left,
right, or up) inside of the room using an optional deep shroud.
See page 15.
When venting through the wall, be sure to leave 2-3/8” (51mm)
of ue pipe extending through the rear shroud into the room for
connection to the inducer. See Figure 40.
Figure 39
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.

VENTING
To prevent ue pipe from pushing back into the wall, place a hose
clamp on the pipe against the wall and tighten. See Figure 41.
Figure 41
For direct-vent installations, the inlet air pipe will only extend
1/4” through the wall into the rear shroud. The inlet pipe will butt
against the stopping ange provided with the air pipe kit. See
Figure 42.
Attach the transition box to the back of the wall furnace with six
10 x 1/2” hex-head screws. See Figure 44.
Figure 44
Carefully push the wall furnace back into position against the rear
shroud and connect the ue pipe to the inducer.
Attach the wall furnace to the rear shroud by using four 10 x 1/2”
(13mm) hex-head screws previously removed (see page 21). See
Figure 45. Do not tighten the screws.
Reinstall the lter door by inserting the lter door tabs into the
two receiving slots on top of the rear shroud. Close the lter door,
then adjust the wall furnace positions to minimize the gap be-
tween the wall furnace casing and the lter door. Tighten the four
wall shroud screws to secure the wall furnace in place.
Figure 42
Due to the high efciency of the Ultra Saver, condensate will form
in the heat exchanger and ue pipe. A condensate trap and drain
tube are provided to dispose of the condensate to a nearby oor
drain. An optional humidication tray is also available to evapo-
rate the condensate back into the room as humidity instead of
draining it away from the wall furnace. See page 15.
If draining the condensate away from the wall furnace, route the
condensate drain tube provided in the instruction envelope to the
elbow on the tube sticking through the back of the wall furnace
to a nearby drain. See Figure 43. The elbow may be rotated to
direct the hose to either side or straight down. Eliminate all sags
or dips as they may prevent drainage. An optional drain tube
extension kit and optional condensate pump kit accessory are
available. See page 15.
Notice: Due to the mildly acidic nature of wall furnace condensation, check with local authorities to determine if a ph neutralizing
process may be required.
Figure 45
Notice: For oor mounted wall furnaces, ensure the adjustable
legs are all on the oor.
To complete inside installation open the lter door and, tighten
the inducer hose clamp with a 10-inch 5/16” nut driver. See
Figure 46.

VENT EXAMPLES FOR SINGLE FLUE
Max Vent Run - 50 ft. Equivalent
When installing a horizontal vent termination, the minimum vent
length protruding from the outside wall is 10 inches (304mm). See
Figure 47.
For venting cap, exhaust with 45° elbow.
Notice: Horizontal discharge 45° elbow must be pointed down-
ward. See Figure 47.
Notice: All horizontal runs require a 1/4” per foot rise to run con-
densation back to the wall furnace.
Notice: For each 45° elbow installed, the length of the run
MUST be reduced by 1.5 feet (45 cm). Reduce the length of the
run three feet (91.4 cm) for every 90° elbow. The vent terminal
elbow does not contribute to the overall vent length measure-
ment.
