Orifice Size/Altitude Adjustment

The Epic™ Stove

For altitudes above 2,000 feet (In Canada 4,500 FT/1370
M),the orifice should be de-rated by 4% for every 1,000 feet
to maintain the proper ratio of gas to air. Improper orifice
sizing may result in damage and unsafe conditions. Chang
ing the orifice should only be done by a qualified service
technician. Contact your Lennox Hearth Products dealer for
proper orifice sizes. (see Page 26 for more information).

Smoke Detectors

Since there are always several potential sources of fire in
any home, we recommend installing smoke detectors. If
possible, install the smoke detector in a hallway adjacent
to the room (to reduce the possibility of occasional false
activation from the heat produced by the appliance). If your
local code requires a smoke detector be installed within
the same room, you must follow the requirements of your
local code. Check with your local building department for
requirements in your area.

Venting

This stove can be vented with Security™ Secure Vent™
pipe*. Coaxial pipe diameters are 6-5/8” outer and 4” inner.
The combustion air for this stove is drawn from outside the
house through the outer DV (direct vent) pipe. Room air is
not required for combustion.

When planning your installation, select the correct length of
vent pipe for your particular requirements. Determine the
minimum clearance to combustibles from the rear of the
unit to the wall. It is also important to note the thickness of
the wall. Before cutting the vent hole through the wall make
sure that ALL vent and termination clearances (see Page

17) will be met.

Electrical

The standard fan motor requires 120 Volts AC for operation.
The stove is not dependent on the fan or an outside electri
cal supply to operate.

Instructions - This appliance is equipped with a three­prong (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.

* Other approved chimney brand is Simpson Dura-Vent DV-GS.

WARNING - Electrical Grounding

Millivolt Valve

This stove is operated with a millivolt valve and therefore
burns even during a power outage.

Fuel

This stove comes from the factory equipped to burn natural
gas at a specified elevation. The stove can be converted to
burn LP gas (liquid propane) by changing the cassette (valve
and pilot assembly) or installing a conversion kit. Only Len
nox Hearth Products conversion kits can be used to convert
from NG to LP or LP to NG. Contact your Lennox Hearth

If logs are not installed according to the log installation
instructions, flame impingement and improper combustion
could occur and result in soot and/or excessive production of
carbon monoxide (CO), a colorless, odorless, toxic gas.

The size and position of the log set is critical to achieve
a safe, reliable and attractive flame pattern. Any attempt
to use a different log set in the fireplace will void the war­ranty and will result in incomplete combustion, sooting
and poor flame quality.

Vent Installation

Venting:

The Epic™ gas stove has been tested and listed as a direct
vent heater system by OMNI-Test Laboratories, Beaver­ton, Oregon and is recommended for use with Security™
Secure Vent pipe*. Use only approved chimney brands
with this appliance.

Important:

• Read all instructions carefully before starting the instal
lation. Failure to follow these instructions may create a
fire or other safety hazard and will void the warranty.
Be sure to check for specific clearances to combustible
requirements on Page 8.

Do not extend the venting sys­tem vertically or horizontally in excess of the distance
prescribed on Page 16. Consult your local building codes

before beginning the installation.

• Always maintain the proper air spaces between the

vent pipe and nearby combustibles to prevent a fire
hazard. Do not fill air spaces with insulation. Be sure to

check the vent termination clearance requirements from
decks, windows, soffits, gas regulators, air supply inlets
and public walkways, as specified in these installation
instructions on Page 17 and local building codes.

• This gas stove and vent system must be vented directly

to the outside of the building and never be attached to
a chimney serving a separate solid fuel or gas-burning
appliance. Each direct vent gas appliance must use its

own separate vent system. Common vent systems are
prohibited.

• The Epic gas stove is recommended for use with Security™
Secure Vent pipe*. The appliances and vent manufactur
ers warranties will be voided and serious fire, health, or
other safety hazards may result from any of the following
actions:

• Installation of any damaged direct vent component.

• Unauthorized modification of the direct vent system.

• Installation of any vent component part not approved
or manufactured by the approved vent manufacturer.

• Installation other than as instructed by Lennox Hearth
Products and vent manufacturers instructions.

Residential and Mobile Home Installations:

These are the minimum pieces required. Other parts may
be required for your particular installation.

Optional Components:

• 45º Elbow

• Vinyl Siding Shield for Riser Vent Terminal

• Vent Guard

• Snorkel Termination (36”)

• Snorkel Termination (14”)

• Wall Penetration Heat Shield

Vent Considerations:

Twist-lock procedure: Four indentations on female ends of

pipes and fittings are designed to slide straight onto male
ends of adjacent pipes and fittings by orienting the four pipe

-

indentations so they match and slide into the four entry slots.
Push pipe sections completely together, then twist-lock one
section clockwise approximately one-quarter turn until the
two sections are fully locked. The female locking lugs will not
be visible from the outside on the pipe or fittings. They may
be located by examining the inside of the female ends.

Supports: Horizontal runs of vent must be supported every
3 feet. Wall straps are available for this purpose.

Pipe Sealing: If Simpson Dura-Vent pipe is used, the pipe
must be sealed as follows: seal both the inner and outer pipes
with a high temperature silicone sealant rated for at least
600ºF (commonly know as “RTV”). Run a 1/8” (3mm) bead
of silicone around outside of male end of outer sleeve. Run
a 1/8” (3mm) bead of silicone about 1/4” (6mm) from the
end of the male inner pipe, which is found in the pipe to be
attached above. Twist-lock the pipes or fittings together.

2. All horizontally terminated vent installations may only use
6-5/8”x 4” Security™ Secure Vent pipe*.

3. Assemble the desired combination of pipe and elbow(s)
to the appliance adapter with pipe seams facing down.
Offsetting the pipe seams as double seams in one place
will cause the outer pipe to take an oval shape.

4. When this pipe passes through a wall, a wall thimble

- Simpson #942 or Security™ #SV4RSM - is required.
The hole in the wall for the wall thimble should be 9-1/4”x
10-1/4”. If the wall being penetrated is constructed of non­combustible material (i.e. masonry block or concrete), a
7” diameter hole is acceptable and a wall thimble is not
required.

5. Horizontal runs of vent pipe must be supported every 3
feet. Wall straps - Simpson #988 or Security™ #SV4BM

- are available for this purpose.

6. If the vent passes through a ceiling or floor, a firestop

- Simpson #963 or Security™ #SV4BF - is required.

7. Also note that venting terminals shall not be recessed
into a wall or siding. If installing the termination cap on
a wall covered with vinyl siding, a vinyl siding standoff

- Simpson #950 or Security™ #SV4VS - or furring strips
must be used to ensure that the termination cap is not
recessed into the siding.

8. The horizontal run of vent should have a 1/4” (6mm)
rise for every 12” of run toward the termination. Never
allow the vent to run downward. This could cause high
temperatures and may present the possibility of a fire.

9. The location of the horizontal vent termination on an ex
terior wall must meet all local and national building codes
and must not be blocked or obstructed. For allowable
external vent termination locations see Page 17

.

10. Allowable clearances from the vent pipe to combustible
materials must be maintained. See Page 8 for these clear
ances.

11. Do not locate the termination cap where it may be blocked
by shrubbery or snow.

storm collar - Simpson #953 or Security™ #SV4FC - are

required.

4. A 1-inch clearance from the vent pipe to combustible
materials must be maintained.

5. A maximum of either two 45º elbows or two 90º elbows
may be used. See Page 16 for allowable offsets.

6. The maximum system height is 30 feet (9.1M) and the
minimum is 10 feet (3M).

Flue Restrictors

This stove requires a balanced flue to ensure proper com­bustion. As such, flue restrictors may need to be installed
depending on the vent configuration of your stove. The

drawings on the next page show all the allowable pipe con

figurations for the Epic™ gas stove. To properly install the
flue restrictors, find your pipe configuration in the drawings
on the next page and note which restrictor setting is recom
mended. The flue restrictors are shipped in the firebox of
your stove. Install the flue restrictors using the four allen
head screws according to the diagram below. Install the
flue restrictor screws in their original holes in the top of
the firebox. Restrictor positions are based on tests run in
a laboratory.

Gas Line Installation

Check all connections
for leaks using a gas
leak test solution.

This stove must be connected to the gas line in accordance
with local codes and/or the National Fuel Gas Code, ANSI
Z223.1 (In Canada, the current CAN/CSA B149.1 installa
tion code). Remove the four screws holding the back of
the pedestal in place. Slide rear cover back far enough to
gain access to the inside of the pedestal. Remove plastic
plug from the 3/8”x 9” pipe. Connect gas line to the 3/8”x 9”
pipe. After connecting the gas line, all joints in the line and
connections at the valve should be checked for leaks before
final positioning of the unit. Conduct a gas leakage test of
the appliance piping and control system downstream of the
shutoff valve in the supply line to the appliance.

Gas Pressure Requirements

A MAJOR CAUSE OF OPERATING PROBLEMS WITH GAS
APPLIANCES IS IMPROPER GAS PRESSURE!

The most important item to check during the initial
installation and the first thing to check when operating
problems occur is gas pressure! This appliance will
not function properly unless the required gas pressure
is supplied. See the table on this page for gas pressure
requirements.

Two pressure taps are provided on the stove’s valve to
check gas pressures. To access the taps, remove the four
socket head screws from the valve control panel. The taps
are located below the On/Off/Pilot knob (see Figure 20 on

Page 20

To check inlet pressure (with the stove burning) insert a
small flat-bladed screwdriver into the tap and turn a half­turn counterclockwise. Cover the tap with the line from the
manometer and check the pressure. Close the tap gently
but securely after completing the check. The manifold
(outlet) tap is to the right of the inlet tap. To check manifold
pressure (with the stove burning at the high burn setting)
insert a small flat-bladed screwdriver into the tap and turn a
half-turn counterclockwise. Cover the tap with the line from
the manometer and check the pressure. Again close the tap
gently but securely after completing the check. Check the
taps for gas leaks with a gas leak test solution (retighten if
necessary).

If the pressure is not sufficient, make sure the gas supply
line is large enough, the supply regulator is properly adjusted
and the total gas load for the residence does not exceed the
amount supplied.

The appliance and its individual shut off 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.

The appliance must be isolated from the gas supply piping
system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping system
at test pressures equal to or less than 1/2 psig. Check
with your gas supplier or plumber.

Flame Color and Behavior

Your stove is designed for maximum heating efficiency.
Therefore, upon lighting of the main burner the flames will
be semitransparent or “bluish.” After 10-20 minutes of
operation, the logs will heat up and the flames will become
a yellow/orange color.

Adjusting the stove to cause the flames to turn orange sooner
may result in poor combustion, sooting and a hazardous
situation. See the drawing to the right showing proper flame
appearance.

to a properly installed and maintained venting
system can result in carbon monoxide (CO)
poisoning and possible death.

carbon monoxide poisoning resemble the flu
with headaches, dizziness, or nausea. If you
have these signs, get fresh air at once! Have
the heater inspected by a qualified service
technician. Some people are more affected by
carbon monoxide than others. These include
pregnant women, people with heart or lung
disease or anemia, those under the influence
of alcohol and those at high altitudes.

When testing for proper operation - If an optional thermo
stat is installed adjust it to its highest temperature setting.
Visually determine that main burner gas is burning properly:
i.e., no floating, lifting or flashback. Adjust the primary air
shutter(s) as required. Check for proper main burner opera
tion at both high and low flame.

Quiet Operation

As the Epic gas stove is burning, a number of normal op­erational sounds may be heard. The flow of gas through the
gas valve and orifice may make a rushing or whistling noise.
If this noise is objectionable, it can be reduced by turning
down the flame. Turning down the flame can reduce total
heat output by more than 30%. When the blower turns on,
the sound of rushing air may be heard. The blower sounds
may be reduced by adjusting the speed control located on the
blower assembly. Also, a slight clicking sound may be heard
as the gas valve or blower switch is turned on and off.

Air Shutter Adjustment

CAUTION: Air shutter is hot while the Epic™ gas stove

is operating and should only be adjusted using a heat

resistant glove.

The air shutter control lever is located inside the main

control door above the control panel. The lever is linked to

the primary air shutter on the main burner. The air shutter

regulates the amount of primary air the burner receives

and, therefore, how clean the stove burns. The air shut

ter should only be adjusted by a qualified gas technician.

The stove should burn for about 15 minutes with the logs

installed before adjusting the air shutter. Moving the lever

to the left (closing the shutter) will raise the height of the

flames as well as turn them more yellow/orange. Moving

the lever to the right will open the shutter, turning the flames

to a cleaner transparent blue and enhance the glow of the

logs.

CAUTION: The air shutter should never be set so as
to make the tips of the flames sooty or create sooting on
the viewing glass, logs, or firebox ceiling. If soot begins
to form after burning, the air shutter should be opened
gradually until the sooting condition stops. Gas quality
and gas pressure may vary, which can affect the burning
characteristics of the stove.

Paint Curing

This stove has been painted with Stove Bright high tempera­ture metallic paint. It leaves the factory dry to the touch, but
completes the curing process as the stove is used. To cure
the paint, burn the appliance four successive times for ten
minutes each time with a five minute cool down between
each firing. Also some parts of the appliance may be lightly
coated with machining oil. Ventilate the house during these
first firings as the paint and oil give off carbon dioxide and
unpleasant odors. It is recommended that persons sensi

­tive to an imbalance in the indoor air quality avoid the stove

during the curing process.

Optional Wall Thermostat

If an optional wall thermostat is to be installed, install the
thermostat per the manufacturers instructions (provided with
the thermostat). Failure to follow manufacturers instructions
could result in a malfunction. Pay special attention to the
thermostat location requirements. If the location require
ments are not adhered to the appliance, erratic operation
or failure may occur.

Do not mount the thermostat where it may be affected by:

Operating Options

Your stove comes equipped with an “On/Off” rocker switch
used to turn the burner on and off while the pilot light is
on. The switch is a round rocker switch located behind the
main control panel door.

A millivolt wall thermostat, or a remote control, can be used
to supplement the rocker switch. The gas valve is powered
by millivolts generated by the pilot assembly. This millivolt
system is very sensitive to electrical resistance, therefore,

make sure all connections are tight, clean and free from
corrosion. Do not splice any millivolt wires. Consult the
table below to determine the proper gage of wire for the

thermostat or wall switch connections. This table refers

to the total length of the wire (out to the switch and back).

The thermostat must be a millivolt type. A 24-volt furnace
thermostat will not work. Never hook up household current

- 120 Volts - to the millivolt system. It is not recommended

to hook up any more than two switches to the stove (for

example a rocker switch and a wall thermostat). Additional

switches may affect the system resistance and increase the

chance of the burner not igniting.

Follow the instructions included with the thermostat or
remote control for wiring. The thermostat, remote control
and rocker switch will turn the burner on and off indepen
dently. Be sure to set the rocker switch to the “Off” position
when using the thermostat or remote control and set the
thermostat or remote control to the lowest temperature when
you wish to use the rocker switch only, otherwise one may
override the other.

Millivolt Control System

This stove operates on a millivolt control system. As such,
no additional power supply is needed for the stove to heat.
The pilot assembly contains a thermocouple that, when
heated by the pilot flame, generates electricity (millivolts­mV=1/1000 of a volt) which opens a valve allowing gas to
continue flowing to the pilot assembly. The pilot assembly
also contains a thermopile that, when heated by the pilot
flame, generates electricity that flows to terminal #1 (labeled
TPTH) on the gas valve. When the electricity is conducted
from terminal #1 through the on/off switch, thermostat, or
receiver of the remote control to terminal #3 (labeled TH)
on the gas valve, the main burner will ignite.

Maintenance and Servicing

2. The viewing glass should be cleaned periodically (see
Glass Door Cleaning and Maintenance).

Maintenance Checklist:

The following should only be performed by a qualified
service technician.

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

servicing.

1. Annual inspection should be made and the following
checks performed:

oWhen unit is cool, open glass viewing door and inspect

burner for dirt, soot and lint accumulations and remove
if necessary. If excessive soot accumulation is present
on burner, have a qualified service technician adjust
burner for proper combustion.

oClean inside of glass viewing door with gas fireplace

glass cleaner. NEVER attempt to open door or clean
glass when unit is hot.

oCheck the hot air outlet vents for lint or other accumula-

tions. Never block or restrict vent openings or obstruct
flow of ventilation air.

oCheck that direct vent pipe, air intake and flue are open

and free of soot, blockage, or debris.

oCheck gaskets once a year. Gaskets must be tight. Replace

if necessary.

oInspect the pilot system for proper flame. NEVER ADJUST

THE PILOT until after the gas pressure has been checked
and supply lines have been completely bled (this may
take an hour or more when bleeding through the pilot).
All pilots are checked and burned at the factory prior to
shipment. The pilot adjustment screw is located to the
lower left of the flame height control knob.

.2 Adjust the pilot screw to properly size the flames. The

flames should completely surround the thermopile
and thermocouple and extend across the main burner
tube ports. Be careful not to back the screw out of its
threads.

oCheck that the area around the stove is kept clear and

is free of combustible materials, gasoline and other
flammable vapors and liquids.

oCheck the millivolt system as per the table on this

page.

3. Should repairs or maintenance of the stove require
the disassembly of the vent/air intake system, the
reassembly and resealing should be completed by a
qualified service technician and follow the instructions

Vent Pipe Maintenance

Glass Door Cleaning and Maintenance

Conduct an inspection of the venting system semiannually.
Recommended areas to inspect are as follows:

1. Check areas of the venting system which are exposed to
the elements for corrosion. These will appear as rust spots,
streaks, or, in extreme cases, holes. These components
should immediately be replaced.

2. Remove the cap and shine a flashlight down the vent.
Remove any bird nests or other foreign material.

3. Check for evidence of excessive condensate, such as
water droplets forming in the inner liner and subsequently
dripping out at joints. Continuous condensate can cause
corrosion of caps, pipe and fittings. It may be caused by
having excessive lateral runs, too many elbows, or exterior
portions of the system being exposed to cold weather.

4. Inspect joints to verify that no pipe sections or fittings have
been disturbed and consequently loosened. Also check
mechanical supports such as wall straps or plumbers’
tape for rigidity.

Cleaning: When cool, the glass may be cleaned with a clean,
soft cloth and glass cleaner. For cleaning white condensation
from the interior glass use KEL KEM gas stove glass cleaner
available from your stove dealer. Use of caustic or abrasive
cleaners may damage glass. Gold or nickel plated trim must
be cleaned with glass cleaner or denatured alcohol and a
soft cloth before firing or fingerprints and stains will remain
permanently. Never use abrasive polish to clean the gold or
nickel as it will ruin the finish. DO NOT operate stove with
broken glass. DO NOT clean door or glass when hot. DO
NOT abuse glass door by striking or slamming shut. DO NOT
use substitute materials if replacing glass. DO NOT spray
commercial glass cleaner with ammonia on the door and
glass gasket as it may dissolve the gasket glue.

WARNING: Do not operate appliance with the glass panel
removed, cracked, or broken. Do not remove glass door
while the stove is hot. Replacement of the glass door
should be done by a qualified service technician.

Glass Replacement: If the glass in your door is damaged

or broken, the complete door assembly (including gaskets)
must be replaced using part number H3102. The replace
ment door assembly is available from your Lennox Hearth
Products dealer. The glass is neo-ceramic and alternative
types must not be used. See Page 25 for door assembly
replacement instructions.
