INSTALLING FIREPLACE

Select a suitable location that is not suscep-

tible to moisture and is away from drapes,

furniture and high trafc areas. Note: Follow

all national and local electrical codes. This

insert can be installed into either an existing

replace or as new construction/renovation.

NOTICE: Never pick unit up by

louvers. Louvers will bend.

Existing Fireplace Installation

1. Thoroughly clean out the existing replace

and hearth area.

2. Seal all drafts, vents or ash clean-outs

with berglass insulation. Seal the ue.

Once sealed, close damper to stop debris

from falling onto unit.

3. If existing re box is susceptible to mois-

ture, cap the top of the chimney ue to

prevent infiltration of water. Note: It is

strongly advised that you hire a qualied

professional to undertake this step in order

to prevent personal injury. Once the ue is

capped, the chimney is no longer suitable

for wood burning. Note: Do not install this

unit into a replace that is prone to damp-

ness; the area of installation must be dry.

4. Plan the power supply. If an existing

grounded outlet is near the replace, the

power cord can run along the front of the

replace. If the cord is not long enough

to reach the outlet, a grounded extension

cord minimum AWG No. 14 and rated to

a minimum of 1875 watts may be used. If

you plan to cut or drill a hole in the exist-

ing replace for wiring, it is best to hire

a professional to do this step in order to

prevent personal injury. To reduce the risk

of re, do not run the power cord under

rugs, carpets, etc. Arrange the power

supply cord away from high trafc areas

where it may pose a tripping hazard.

WARNING: The solid fuel/gas

replace has been converted for

use with an electric insert and

cannot be used for original fuels

unless all original parts have

been replaced and the replace

has been reapproved by the au-

thority having jurisdiction.

INSTALLATION

WARNING-RISKOFFIRE!The

power cord must not be pinched

or against a sharp edge. Secure

cordtoavoidtrippingorsnagging

to reduce the risk of re, electric

shock or personal injury.

Do not run cord under carpet-

ing. Do not cover cord with

throw rugs, runners or the like.

Arrange cord away from trafc

areas and where it will not be

tripped over.

WARNING - RISK OF FIRE!

To prevent a possible re, do

not block air intake or exhaust

in any manner. Do not use on

soft surfaces where openings

may become blocked.

WARNING - RISK OF FIRE!

Do not blow or place insulation

against the rebox.

WARNING: This heater is

tested and listed for use only

with the approved optional ac-

cessories. Use of optional ac-

cessories not specically tested

for this heater could void the

heater warranty and/or result in

a safety hazard.

WARNING: If the informa-

tion in these instructions is

not followed exactly, a re or

explosion may result causing

property damage, personal in-

jury or death.

Do not store or use gasoline

or other ammable vapors in

the vicinity of this or any other

heater.

New Construction or Renovation

1. Select a location away from combustible

materials such as curtains or drapes,

furniture, bedding, paper, etc.

2. Place unit in selected location to see how

it will look in the future.

3. Mark the desired location on the oor

and store unit in a safe, dry and dust free

location.

4. Frame in an opening leaving at least 1/4"

(6 mm) around the edge of the unit. Any

new wiring must be done in compliance

with local and national codes and other

applicable regulations in order to reduce

the risk of re, electric shock or other inju-

ries. Therefore, it strongly recommended

that you hire a professional to complete

any such work.

5. Plan you power supply route. See step 4

of Existing Fireplace Installation, page 6.

INSTALLATION

Continued

Installing Insert

Once the site has been prepared, the replace

insert can be installed.

1. Install trim onto front of unit.

2. Make sure power switch is in the OFF

position.

3. Plug replace into a 15-amp/120 volt,

grounded outlet.

4. Push replace insert so that the trim is

against the nished mantle or wall sur-

face.

NOTICE: When the front is

installed it will cover the gap

between the heater and framing,

cabinet, nishing materials or

existing replace.

FINISHING

Combustible Finishing Material: Materials

made of or surfaced with wood, compressed

paper, plant bers, plastics or any material

capable of igniting and burning, whether ame

proofed or not, plastered or unplastered (this

includes drywall).

Noncombustible Finishing Material: Ma-

terials which will not ignite and burn. Such

materials are those consisting entirely of

steel, iron, brick, tile, concrete, slate, glass

or plasters or combinations thereof or have a

re rating of zero.

WARNING: Grills on this

heater cannot, in any way, be

covered as it may create a re

hazard.

FINISHING CHECKLIST

• Power supply service must be completed

prior to nishing to avoid reconstruction.

• Grills and air openings cannot be covered

in any circumstances.

Note: The heater is a zero clearance replace

and may be nished with combustible or non-

combustible nishing materials.

When using paint or lacquer to nish the

mantel, they must be heat resistant to prevent

discoloration.
