SAFETY INFORMATION FOR USERS OF LP-GAS
LP-Gas (Propane) 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, 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.
• 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 sus-
pect 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
SOME POINTS TO REMEMBER
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.

VENTING REQUIREMENTS
WARNING
This appliance must not be vented with any other
appliances, even if that appliance is of the condensing type.
Common venting can result in severe corrosion of other
appliances or their venting and can allow combustion
gases to escape through such appliances or vents. Do
not vent the heater into a replace chimney or building
chase.
WARNING
Upon completion of the installation, carefully inspect the
entire ue system to assure it is properly sealed. DO NOT
use any vent material other than what is specied in this
manual. Leaks in the ue system can result in serious
personal injury or death due to exposure of ue prod-
ucts, including carbon monoxide.
The Mantis is classied as a “Category IV” appliance, which
requires special venting materials and installation procedures.
Installations can be Conventional (1-pipe) and Direct Vent
(2-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.
Installation in Canada must conform to the requirements of
CSA B149 code. Vent systems must be composed of pipe, ttings, cements, and primers listed to ULC S636. In Canada,
the primer and cement must be of the same manufacturer as
the vent system; do not mix primers and cements from one
manufacturer with a vent system from a different manufacturer.
Follow the manufacturer’s instructions the use of primer and
cement and never use primer or cement beyond its expiration
date.
The safe operation, as dened by ULC S636, of the vent system
is based on following these installation instructions, the vent
system manufacturer’s installation instructions, and proper use
of primer and cement. Acceptability under Canadian standard
CSA B149 is dependent upon full compliance with all installa-
tion instructions. Under this standard, it is recommended that
the vent system be checked once a year by qualied service
personnel. The authority having jurisdiction (gas inspection
authority, municipal building department, re department, etc)
should be consulted before installation to determine the need
to obtain a permit.
The maximum vent length is 40 feet equivalent with
(3) 90° elbows. The minimum vent length is 12 inches. Each 90° elbow used in the vent system will be the
equivalent to 3 feet, and each 45° elbow is equivalent to

VENTING REQUIREMENTS
It is recommended that the Mantis Power-Vent High-Efciency
Fireplace be located on an exterior wall for ease of venting.
The ue exhaust pipe and inlet air pipe should be located between wall studs. The required opening for venting is 1-7/8
inch in diameter for 1-1/2 inch PVC pipe.
The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12 inches. The ue outlet must be at least 12 inches from any opening which ue gases
could enter the building. See Figure 1. The ue outlet must be a
minimum distance of 6 feet from any pressure regulator.
The bottom of the exhaust vent terminal and the air intake shall
be located at least 12 inches above grade and must be vented
outside. It is recommended the exhaust and intake be located
12 inches from the maximum snow level.
The ue pipe must be supported on horizontal vent runs. The
ue pipe needs to be supported every 3 feet. All horizontal
runs of the ue must be pitched ¼ inch per foot either towards
the heater or away from the heater.
Note: If the vent run dips or sags, condensation may be-
come trapped and cause the unit to not operate properly.
The minimum vent length protruding from outside the wall is
6 inches. For two-pipe installation, a minimum distance of 3
inches and maximum distance of 24 inches must be maintained between the pipes. See Figures 2 and 3.
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. Insulating pipe
is important to avoid condensate icing.
For proper operation, the ue exhaust must be extended 6
inches from the outside wall before applying an elbow.
Figure 4
Single ue (one-pipe) installations must have a minimum
clearance of 2 inches on the back of the heater for combustion
air.
Note: If the vent length requirements are not followed, the
unit will not operate properly.

Figure 13 displays a single ue (one-pipe) installation. Because
the distance from the replace to the rst elbow is more than 6
inches, the rst 90° elbow must be considered into the total vent
length. The equivalent length of the second 90° elbow also needs
to be added to the total length, but the third elbow does not since
it is the ue terminal. The total horizontal vent length of the ue
system is 7 feet, and the total vertical length is 27 feet. The two
90° elbows are equivalent to 6 feet, bringing the total to 40 feet.
Figure 14 is an example of how the replace can be vented if the
ue outlet is below the level of the oor.
H = 5’ + 2’ = 7’
V = 27’

PVCA HORIZONTAL COLINEAR DIRECT VENT ADAPTOR
Colinear adaptor to be used in conjunction with single ue horizontal vent kit PVVK-SH636. The two attachments are used
for colinear direct vent installation.
Colinear adaptor
1. Attach colinear adaptor to back of replace with two (2)
screws.
2. When adapter is connected, continue with your vent
run. Cementing PVC joint is recommended, but not
required on colinear fresh air intake adaptor.

DIRECT VENT COLINEAR VENT EXAMPLES
Max Vent Run - 40 ft. Equivalent With Three (3) 90° Elbows
Special Note: The vent terminal 90° elbow and rst 90° elbow
off back of the fireplace, when within 6” (15.2 cm), do not contribute to the overall vent length measurement. For each 45°
elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 1.5 feet (45 cm). This does not
apply if the 45° elbows are installed on the vertical part of the
vent system. Reduce the length of the horizontal run 3 feet
(91.4 cm) for every 90° elbow.
Figure 17 displays a two-pipe installation. Because the distance
from the replace to the rst elbow is more than 6 inches, the
equivalent length allowance for the rst 90° elbow must be added
to the total vent length. The equivalent length of the second 90°
elbow also needs to be added to the total length. The third el-
bow also needs to be included. The equivalent length of the PTrap
does not need to be added since it is the termination. The total
horizontal vent length of the ue system is 11 feet, and the total
vertical length is 20 feet. The three 90° elbows are equivalent to 9
feet, bringing the total to 40 feet.
Note: The exhaust must be a minimum of 3 inches above the inlet
air pipe. The ue must be at least 12 inches from the roof line, and
it is recommended to be at least 12 inches above the maximum
expected snow level as indicated in Figures 12 through 20.
Note: Exhaust must be a
minimum of 3 inches above
air intake inlet.
Note: On horizontal runs, a support clamp needs to be installed
every 3 feet. Do not allow “sags” in horizontal vent runs; water will
settle in the pipe.
When installing a colinear horizontal, the minimum vent length
protruding from the outside wall is 6” (15.2 cm) for air intake and 9”
for exhaust. See Figure 18.
Note: Horizontal discharge 90° elbow must be pointed downward.
See Figure 18. All horizontal runs require either a 1/4” per foot rise
to run condensation back to the fireplace, or a 1/4” per foot down-
ward slope to run condensation away from the fireplace.
Note: All PVC vent run piping can be purchased at a local hard-
ware store. Schedule 40 PVC pipe should be used and cemented.
See page 10. PVVK-SH636 Horizontal Vent Adaptor Kit is available from Empire Comfort Systems, Inc.
For horizontal colinear direct venting, exhaust and intake air, cap
pipes with 90º elbows, pointed downward.
Note: The measurement for center to center of the pipes can be
3” to 24” maximum.
