SAFETY INFORMATION FOR USERS OF LP-GAS

Propane (LP-Gas) is a flammable gas which can cause fires 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 mem-

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
firefighters declare them to be safe.

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 find 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 filter the odorant. Odorants

bers 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.

• Use your neighbor’s phone and call a trained LP-Gas ser
vice person and the fire 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 firefighters 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.

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. Imme
diately 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 find 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 qualified, do not light pilot lights, perform ser
vice, or make adjustments to appliances on the LP-Gas sys­tem. If you are qualified, 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 filled and allowed

to set too long before refilling. 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 orifices. 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
refilled before it is completely empty.

Figure 1

Installing a New Main Gas Cock

Each appliance should have its own manual gas cock.

A manual main gas cock should be located in the vicinity of the
unit. Where none exists, or where its size or location is not ad
equate, contact your local authorized installer for installation or
relocation.

Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.

Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!

A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required
by the National Fuel Gas Code that a drip line be installed near
the gas inlet. This should consist of a vertical length of pipe tee
connected into the gas line that is capped on the bottom in which
condensation and foreign particles may collect.

Pressure Testing of the Gas Supply System

1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.

plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.

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 (3.5 kPa).

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 (3.5 kPa).

Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the fireplace gas valve, it will
result in a hazardous condition.

Checking Manifold Pressure

Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5" w.c. (.872kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 5.0" w.c.
(1.245kPa) for the purpose of input adjustment to a maximum of

10.5" w.c. (2.614kPa) Propane gas models will have a manifold

pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 11.0" w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of

13.0" w.c. (3.237kPa).

A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the outlet side of the gas control.

CLEARANCES FOR DIRECT VENT

1 9/16”

4 3/32”

1. Pick a location on a wall with a clear space in the room. In
selecting a location for installation, it is necessary to provide
adequate accessibility clearances for servicing and proper
installation. Be sure to locate the unit close enough to a 110
VAC wall receptacle to properly power appliance.

2. When facing the front of the furnace the minimum clearances
from casing to combustible construction are 0” (0mm) on top,
0” (0mm) on each side, recommend 4” (102mm) on sides for
servicing and 0”(0mm) from the floor and 0” (0mm) to rear
wall.

3. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12” (305mm).

4. The minimum wall depth is 4” (102mm) and the maximum is
48” (121.92cm).

The vent terminal of a direct vent appliance, with an input of
50,000 BTU (14.6KW) per hour or less shall be located at least 9”
(229mm) from any opening through which flue gases could enter
a building.

1. Main Electrical power supply must always be switched on to
the unit with the two burner switches in the off position (up)
before lighting the heater.

2. Turn on main gas supply.

3. Verify that main electrical supply is switched on by checking
the 115V AC power status display (Figures 32 and 33) indica
tor is on.

4. Burner selection: select low burn (front burner), medium
burn (rear burner), or high burn (both burners). Low burn
switch (Figure 32) controls the front burner only. Medium
burn switch (Figure 33) controls the rear burner only. When
both switches are down, they will activate both the low and
medium burners, which is the high setting.

5. Heater operating LED sequence (Front Display Panel). Be
fore starting ensure that the power L.E.D (Figure 34A) is on
and burner switches are off. Switch on the heater by engag­ing the low and medium burner switch, this will activate the
pressure switch and the exhaust fan L.E.D (Figure 34E) will
be on. Also the two burner L.E.D’s (Figure 34C and 34D)
will start flashing for 35 seconds prior to ignition. Once both
burners have ignited, the burner L.E.D’s will remain on. If
you can’t see flame on the rear burner, but the burner L.E.D
is on, then there will be flame there which will become more
visible as the heater warms up. Once the heater warms up
the low speed L.E.D (Figure 34F) will light and the convec
tion fan will blow warm air from the heater. As the heater

becomes warmer, the medium L.E.D (Figure 34G) will come
on. When the heater has reached its highest operating tem
perature, all three L.E.D’s will light up and the convection
fan will now be running at its high speed. Refer to page 30

- Fan Operation. When the heater has been running for some
time, the water pump L.E.D (Figure 34B) may come on to

-

signal that the pump has been activated. Refer to page 33

- Automatic Humidifier Operation.

Note: Three heat settings are available for operating your Mantis

heater - low, medium and high.

a. Low setting (front burner only) - engage low burn switch

only (Figure 32)

b. Medium setting (rear burner only) - engage medium

burner switch only (Figure 33)

c. High setting (front and rear burners).

FAN OPERATION

The 3-speed main convection fan will automatically start approximately 3 to 5 minutes after the heater has warmed up.

Note: The 3-speed main convection fan is automatically controlled and will operate on three preset speeds. Depending on your burner
setting and the surrounding ambient temperature, the L.E.D lights (Page 28, Figure 34) for the fan will light up. The bottom L.E.D light
(Figure 34F) is low speed setting, and middle L.E.D lights (Figure 34G) is the medium speed setting, the bottom, middle and top L.E.D
lights (Figure 34H) is the high-speed setting (both burners on).

Note: The fan will operate totally independent of burner setting - it is controlled by temperature only.

a. Front burner only - low fan speed
b. Rear burner only - medium fan speed
c. Both front and rear burners - high fan speed

On changing the burner setting from high to medium, or from high to low, there will be a delay on the operating speed of the fan until
the firebox has cooled down sufficiently for the fan to change speed.

Note: It can take up to approximately 20-30 minutes before the fan speed will change and settle on the next setting. The firebox tempera­ture and the outside ambient temperature will regulate how quickly the fan responds to speed changes.

HEATER SHUT DOWN INSTRUCTIONS

These are approximates only

}

Turn medium burner switch (Figure 33) and low burner switch (Figure 32) to the “OFF” position.

AUTOMATIC HUMIDIFIER OPERATION

Most gas heaters dry out the air in the room. The Mantis has in­geniously solved this problem with an Automatic Humidifier.
Gas contains moisture which is normally expelled out the flue or
chimney after combustion. But the Mantis is so efficient by taking
92% of the heat out of the burnt gases that the moisture drops out
and condenses in the back of the heater. This water is collected
in a tank which is then pumped up to a stainless steel condensate
tray, where it evaporates in the stream of hot air which is blowing
into your home. Air humidity is automatically restored!

Figure 39

1. The amount of condensate build up in the water sump is dependent on outside temperature, length and height of the flue pipe. The
automatic humidifier can operate from approximately 10 minute to 6 hour intervals, depending on ambient temperature, style and
type of flue. Long single vertical flues can cause the humidifier to come on more often depending on heater settings.

2. When the automatic humidifier is engaged and is transferring the condensate into the holding tank, a hissing sound may be notice
able. This occurs when the condensate enters the holding tank and is quite normal. The duration of the sound may vary from 3 to 30
seconds until the holding tank has been filled with the condensate.

3. When the automatic humidifier pump comes on to pump condensate into the stainless steal tray (located on the top of the heater),
the L.E.D. light (Page 28, Figure 34B) on the front panel will light up and flash while the condensate pump is operating, and then
extinguish after the pump has stopped operating. This means water has been pumped into the tank, and the automatic humidifier
operation will begin.

An optional programmable Remote Control Thermostat can be fit­ted to the heater at the factory when ordered or even after the heat­er has been installed. See your Mantis dealer for correct type.

Installation: The Remote Control can be installed by the owner
of the heater if required. The Remote Control is a battery operated
device, which requires a small amount of low voltage wiring. A
wiring loom package is supplied by Empire Comfort Systems,
Inc. which simply attaches onto the junction box. See Figure 35.

Remove blue jumper wire from junction block and save for fur
ture use. From the remote control receiver, cut and strip one black
wire 1/4” terminal from wire. Attach the stripped black wire to
the blue wire connector from the transformer on the junction box.
From the remote control receiver, attach the Y wiring lead to the
1/4” terminal on the black wire. Attach the one white wire to the
red wire connection from “T1” on the junction block. Attach the
other white wire from the remote control receiver to the black
wire connection from “T2” on the junction block.

Figure 40

In basic terms the red button acts as a Remote Control override
switch for the front burner only. Also the Remote can switch the
heater on and off in the high setting, medium setting or low set­ting.

Note: When the heater or the Remote Control is not being used
for long periods the burner switches should be in the off posi­tion, also in summer the heater should be turned off at the power
point.

Figure 43

Figure 42Figure 41

Economy Display Mode (Red Button Operation): The red but
ton above the two burner switches is called the economy display
mode and will only function when a Remote Control Thermostat
has been installed in the heater. The most common way this button
is used to have the Remote Control set on Thermo mode with a
desired temperature set for the heater to turn on and off, which is
dependant on the ambient temperature, location and the area the
appliance is positioned in. When using a Remote Control Ther­mostat both burner switches need to be in the on position. When
the red button is pressed with both burner switches on, the front
burner only will ignite or if already alight, it will now remain on
regardless of what function or temperature is set on the Remote
Control.

In this situation only the back burner will turn on and off accord
ing to the setting on the Remote Control. By running the heater
this way you will use less gas and still have the aesthetic effect of
the front burner. However, if the appliance is in a small area, this
setting may get to warm for you. To change the setting, press the
red button so that it is not illuminated and the heater will revert
back to its normal operation.

The appliance, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes, with
the National Electrical Code, ANSI/NFPA 70 or Canadian Electri­cal Code, CSA C22.1, if an external electrical source is utilized.

This appliance is equipped with a three-prong [grounding]
plug for your protection against shock hazard and should be
plugged directly into a properly grounded three-prong recep­tacle. Do not cut or remove the grounding prong from this
plug. For an ungrounded receptacle, an adapter, which has two

prongs and a wire for grounding, can be purchased, plugged into
the ungrounded receptacle and its wire connected to the recep­tacle mounting screw. With this wire completing the ground, the
appliance cord plug can be plugged into the adapter and be electri­cally grounded.

CAUTION: Label all wires prior to disconnection when ser­vicing controls. Wiring errors can cause improper and dan­gerous operation. Verify proper operation after servicing.

Note: For testing flame sensor circuit use a micro-amp meter in
series with sensor. Minimum current should be 1 micro-amp dur­ing operation. Be careful as flame sensor is in the 115VAC circuit.
If current is below 1 micro-amp, remove sensor, clean with light
sandpaper and retest.

Note: This heater is equipped with a remote bulb electronic
thermistor control located low on the back of the furnace.
Sometimes due to field locations different air currents may ef­fect the control sensing of the thermistor. This sensing bulb can
be re-located if necessary to provide for better air sensing and
control.

GENERAL INFORMATION

Over Temperature Cut Out

The Mantis Power-Vent High-Efficiency Fireplace is protected
against overheating with a high temperature 80°C (176°F) cut off
switch to protect the heat exchanger, plastic sump and flue fan.

The high temperature cut off switch will automatically switch off
the gas supply to the heater, if the temperature in the room where
the heater is located reaches approximately 28°C (82.4°F). The
heater will go into lock out mode. An allowance of 15 minutes
minimum must be made to allow for the main fan to cool down
the heater prior to restarting the appliance.

Note: In most instances, overheating of the heater is a direct result
of too much lint and dust having accumulated in the main convec­tion fan. This makes the fan unable to supply sufficient air to cool
down the heat exchanger. It is recommended that you inspect your
main convection fan prior to the start of the heating season and if
necessary have it serviced by a qualified service technician (refer
to Page 37 - Maintenance).

Paint Curing - First Firing

The first fire in your heater is part of the paint curing process.
Your Mantis Power-Vent High-Efficiency Fireplace has been
painted with the highest quality heat resistant silicon paint avail­able in the world.

To ensure that the paint is properly cured, light the unit and leave
it burning on high burn for approximately 1 hour.

1. During initial firing of this unit, its paint will bake out, and
smoke will occur. To prevent triggering of smoke alarms,
ventilate the room in which the unit is installed. During initial
firing of logs, you will detect an odor as the logs are cured.
Also, during the curing process the logs will burn with a yel
low flame.

2. Don’t touch the surface of the heater. It will be soft during
this paint-curing phase. Once cured it will not be soft again.

3. The paint finish of the heater should not be cleaned with any
caustic or abrasive cleaning solutions.

4. Any damage to painted surface should be repaired with spe
cial touch paint available from your Mantis Dealer.

MAINTENANCE

Note: Your appliance should be inspected, serviced and checked

annually by a qualified service person to ensure that your
appliance is operating safe and efficiently. Should you
detect any abnormality in the operation of your appli­ance call a qualified service person who has been trained
and approved to inspect and service the appliance. This
may be your installer or dealer (routine service is not
covered under warranty).

Glass Cleaning

It will be necessary to clean the glass periodically. During start­up, condensation, which is normal, forms on the inside of the
glass and causes lint, dust and other airborne particles to cling to
the glass surface. Also, initial paint curing may deposit a slight
film on the glass. It is therefore recommended that the glass be
cleaned two or three times with a non-abrasive household cleaner
and warm water (we recommend gas fireplace glass cleaner) after
the initial burn. We do not recommend using packaged spray type
household glass cleaner. After that, the glass should be cleaned
two or three times during each heating season depending on the
circumstances present.

General Glass Information

Only glass approved for use in Empire Comfort Systems, Inc. fire­place may be used for replacement. The glass replacement must
be done by a licensed or qualified service person.

WARNING

1. The use of substitute glass will void all product warranties.

2. Care must be taken to avoid breakage of the glass.

3. Under no circumstances should this appliance be operated

4. Do not abuse the glass by striking or hitting the glass.

WARNING: Do not use abrasive cleaners on glass. Do not
attempt to clean glass when glass is hot.

UNIT OPERATING FAULTS

SERVICE AND INSTALLATION OF THE APPLIANCE
SHOULD BE CARRIED OUT BY AUTHORIZED PER­SONNEL ONLY.

THE MAJOR CAUSE OF OPERATING PROBLEMS WITH
GAS FIREPLACE HEATERS IS IMPROPER GAS PRES
SURE, INCORRECT LOG PLACEMENT, IMPROPER IN­STALLATION, INCORRECT FLUE INSTALLATION, IN­CORRECT SWITCHING OF BURNERS, DIPS/SPIKES IN
THE INCOMING POWER OR REVERSE POLARITIES.

The above situations can cause such problems as changes in
flame color or configuration, intermittent operations, changes in

RESETTING THE HEATER

There are a number of reasons why sometimes the heater will
switch itself off and is the correct thing for the heater to do in
certain situations (i.e. overheating, power failure or dips, windy
conditions, pump failure, partial or full blockage of flue pipe or no
gas. All of these operations are monitored by the electronic con­trol box inside the heater, which is heat sensitive, pressure switch
sensitive, flame sensitive and water sensitive. If one of these items
is not correct, the heater will shut itself down.

To reset, turn both burner switches to the OFF position, ensure the
red button above the two burner switches is not illuminated (if a
Remote Control is fitted, have it in the off mode). Then turn the
power off at the power point for approximately 10 seconds. Then
turn the power point back on and the power L.E.D. should be illu

heat output, carbon build up or sooting, bad odors, rattles or other
sounds, start up failures and burner(s) switching themselves off.
These are nearly always the result of improper installation or in
correct operation and it may take sometime for these problems
to show themselves. Before calling out a technician you must be

-

able to repeat the fault, try resetting the heater. Read below.

Note: Incorrect installation of the unit, logs, flue pipe, gas pres­sure or operation, which cause the above mentioned faults, are not
covered under warranty and a service call fee will be charged to
correct such problems.

minated. If you have a Remote burner switch and the rear burner
L.E.D. should start flashing, with the flue fan L.E.D. remaining
steady. Wait approximately 60 seconds for the rear burner to ig
nite. You can tell when it has lit, even if you can’t see any flames,
by looking at the rear burner L.E.D. which should remain steady.
Repeat the same process with the front burner. Turn on the front
burner switch and wait approximately 60 seconds and the front
burner L.E.D. will remain steady.

In approximately 5 minutes the convection fan should start and
the heater has been successfully reset.

Note: if the heater is still warm when reset the convection fan
may already be running when the unit is powered up.

22618-4-1106Page 38

LOG PLACEMENT

If for any reason a log should need replacement, you must use the
proper replacement log. Consult your Mantis dealer for correct
replacement logs.

Replacement logs must be installed and positioned as outlined on
pages 16 through 17 under Log Installation.

MAIN CONVECTION FAN

The main convection fan in the heater should be checked, ser­viced and cleaned annually by a qualified service person to ensure
that your appliance is operating efficiently.

Note: Improper positioning of logs can create carbon build up

and will alter the unit’s performance and operation.

Note: If the main convection fan becomes clogged with lint and

dust an over-temperature situation will occur through the
heater exchange system and the over-temperature safety
switch will stop the heater from operating.

HEAT EXCHANGER

The heat exchanger of the unit is located at the rear of the heater.
The heat exchanger should be inspected annually by a qualified
service person for lint and dust build up. Excessive dust and lint
build-up in the heat exchanger can alter the unit’s performance
and operation.

Note: This appliance (Insert and Freestanding Models) needs

to be installed in such a way that the heater (especially
with models built into a fireplace) can be removed at all
times to service the heat exchanger and flue fan, which

22618-4-1106 Page 39

are located at the rear section of the heater.

Under no circumstances should the appliance be installed
under conditions that would not allow for easy removal
of the appliance to carry out routine inspection and ser
vice work on the appliance.
