bLoweR sPeeD:

Convection fan operation is optional, it will come on only when the replace is up
to temperature (approximately 15 minutes). The speed of the fan can be changed

by turning the fan control knob. The blower will continue to operate aut omatically

after the unit has been shut off (approximately 25 minutes).To turn the blower off,
turn the knob counter-clockwise until it “clicks” off (Figure 5).
It is advisable not to operate the blower below

windings of t he blower which could also cause premature fan failure.

aiR shutteR (VentuRi):

The air shutter plays a very important role in ame appearence and combustion quality. The shutter

adjusts how much air gets mixed wit h t he gas before it ignites; adjustment s can be made to accomodate

various climates and vent congurations.

Remove surround to access the air shutter. Find the lever underneath the rebox (see Figure 6). Moving
the lever inward (closed) will make the ame appear more yellow and tall; moving the lever outward
(open) will make the ames appear more blue and short.

Typically natural gas ames will require

the shut t er to be more closed.

Typically LP ames will require the
shutter to be more open.

If you cannot attain a healthy ame by making

air shutter adjustments, you may have the
incorrect restrictor setting or venting problem.

If the ame is very ickery, fast moving, and

low then increase the restriction.

If the ame is very tall, lazy, and dirty then

decrease the restriction.

More details can be found in the venting sect ion
of this manual.

Maintenance And Service

Routine maintenance:

Run through the following procedures to ensure the system is clean and working properly at least once

a year. Check the burner to see if all the ports are clear and clean. Check the pilot to make sure it is not
blocked by anything. The pilot ame should be blue with little or no yellow tips.

WARNI NG: Failure to position parts in accordance with this manual, or failure to use only parts specically

approved with this appliance may result in property damage or personal injury.

The venting system must be periodically examined; it is recommended the examination is done by a

qualied agency.

cLeaninG the GLass:

With the replace cooled, remove the surround panel and glass door (See MaIntenance anD serVIce -
surrounD Panel reMoVal and MaIntenance anD serVIce - Glass Door reMoVal). Check the gasket material

on the back of the glass, making sure that it is attached and intact.

During a cold start up, condensation will sometimes form on the glass. This is a normal condition with
all gas replaces. This condensation can allow dust and lint t o cling t o the glass surface which requires

periodic cleaning.

Initial paint curing of the appliance can leave a slight lm behind the glass, a temporary problem. The

glass will need cleaning about two weeks aft er installation.

Use a mild glass cleaner and a soft cloth. Abrasive cleaners will damage the glass and painted

surfaces. Depending on the amount of use, the glass should require cleaning no more than two or three

times a season.

WARNI NG: Do not clean the glass when it is hot.

cLeaninG the FiRebox:

Carefully remove the glass, they are fragile. Gently remove all the media and place on a paper towel.
Vacuum the bottom of the rebox thoroughly. Carefully clean any dust off the glass and remove any
lint from the burner and pilot. At this time, inspect the burner tube for cracking or severe warping. If a
problem is suspected, contact the dealer. Check the glass for deterioration or large amount s of soot; a

small amount on the bottom side of the glass is normal. Replace the glass as shown in the seconDary

InstallatIon - loG set InstallatIon section. If new/more media is required, contact your nearest ENVIRO

dealer.

RePLacinG the GLass:

The glass in the replace is a high temperature ceramic. If the glass is damaged in any way, a factory

replacement is required (see Parts lIst). Wear gloves when handling damaged glass door assembly

to prevent personal injury. Do not operate with the glass front removed, cracked or broken. Removal

and replacement of the glass from t he door must be done by a licensed or qualied service person.

The glass must be purchased from an ENVIRO dealer. No substitute materials are allowed.

To remove the door (see MaIntenance anD serVIce - Glass Door reMoVal). The replacement glass will
come wit h a new gasket installed. Remove any silicone remnants from the door. Apply high temperature
around the perimeter of the door and install the new piece of glass with gasket. Apply even pressure to
the glass to allow the silicone to adhere to the gasket material.

Maintenance And Service

cLeaninG DecoRatiVe suRFaces:

Painted and porcelain faces should be wiped with a damp cloth periodically. If a plated face has been
purchased, it should be unpackaged carefully to avoid getting anything on the surface of the nish,
including cleaners, polish and nger prints. It is important to note that ngerprints and other marks
can leave a permanent stain on plated nishes. To avoid this, give the face a quick wipe with
denatured alcohol on a soft cloth BEFORE lighting the replace. Never clean the face when it is
hot. Do not use other cleaners as they may leave a residue, which can become permanently etched into

the surface.

suRRounD PaneL RemoVaL:

cooL suRFace FRaminG:

This replace is manufactured with a built-in heat distribution kit, referred to as the Cool Surface System
(CSS). The purpose of the CSS is to dramatically reduce the front wall temperatures above your replace.
This is very useful when delicate objects such as a TV or artwork are mounted above the unit. Using
this feature will also allow you to use combustible facing materials right up to the unit. It is extremely

important these instructions are followed meticulously as any wrong doing could create an overheating

situation which could lead to building re. If the CSS is activated it is crucial that the chase is vented in
accordance to this manual. There are a few different options available to frame your CSS.

Framing Option 1: Front Discharge (ush wall installations) - Construct the framing in a way
that provides a minimum 41
It is essential that these dimensions are respected and not to deviate away from them when using
combustible materials inside the chase (see Figure 24).

Not e: If you wish to construct a similar cutout part way up a tall wall then it is essential to build a false

ceiling inside the chase at the desired height to direct the rising heat out of the gap.

Ensure your chase has been constructed in a manner that vents the chase into the same room. It is not
permitted to vent the chase into an adjoining room. The CSS bleeds heat off the replace into the chase

as opposed to climbing up the front face. This dramatically lowers the front wall temperatures allowing

the placement of delicate objects above the replace. Review the guidelines in the previous sections to

tV instaLLation consiDeRations:

Use of the Cool Surface System is highly recommended when mounting a TV or delicate artwork
above the replace. If the system is not desired, some considerations must be made to ensure above objects

are protected from the heat. A recess, mantel, or a combination of both will be needed for heat protection.

During testing temperatures did not exceed 120F over ambient in a 3

no guarantee that these temperatures will not harm the longevity of your TV. Make sure to consult your TV
manufacture’s specications to nd the maximum allowable operating temperature. Since every home and
installation is unique, temperatures should be veried at the time of install. A TV should not be installed if

temperatures exceed the manufacturers maximum allowable temperature.

Mant el Only I nstallaton: Always maintain minimum clearances (see Figure 37). The total depth of the TV

including the wall mount will determine the minimum allowable mantel depth.

Recess/ Mant el I nstallation: Always maintain minimum recess and mantel clearances (see Figure 38). The

total depth of the TV, including wall mount, and recess will determine the minimum allowable mantel protrusion.

exhaust RestRictoR settinG:

WARNING: Improperly set restrictor setting can cause overheating issues which can lead to
building re.

It may be necessary to adjust the exhaust restrictor in order to control combustion quality and ame

appearance. There are six different restrictor settings.

Determine what restrictor setting you require using the vent graphs in “
co-axIal Vent confIGuratIons. The restrictor is set to 1 when the at edge of the dial is vertical (see Figure

44). Rotate the dial counter-clockwise to increase the restriction level successively until the appropriate
setting is achieved. When the at edge is horizontal the restrictor level is at its maximum (see Figure 43).
The proper setting is crucial for an efcient burn and best possible ame appearance.

It may be necessary to deviate from the recommended setting as different altitudes and climates can
vary the operation of the replace. With LP fueled replaces, it is always a good idea to offer slightly less

restriction for higher altitudes to reduce t he risk of sooting over an extended period.

Step 1. Remove surround panel to gain access to restrictor control.

Step 2. Use a 7/16 socket with long extension to adjust the restrictor dial to desired setting.

Step 3. Allow unit to warn up sufcently and make adjustment as needed.

Step 4. Allow unit to cool down and reinstall surround panel.

hoRizontaL teRmination:

1. A minimum of 18”(NG) or 24”(LP) vertical rise before an elbow is required when

horizontally terminating with an approved venting cap.

2. Horizontal pipes must not be level. For every 12” (305 mm) of horizontal travel there
should be at least ¼” (6.4 mm) of vertical rise. Never allow the vent to run downward, as
this could cause high temperatures or even present the possibility of a re.

3. The exterior of t he horizontal
vent t ermination must not be
blocked or obstructed.

4. If the vent termination is not

four wood screws provided
should be replaced with m aterial

( 2 5 mm) bottom, 3” ( 76 m m) t op, and 3” (76 mm) above elbow.

Step 1.

Set the replace in the desired location. Check to determine if wall studs will be in the way when

the venting system is attached. If this is the case, the location of the replace may have to be

adjusted or t he vent ing may have to be offset.

Step 2. Many direct vent pipe sections are designed with special twist-lock connections. Dry t the

desired combination of pipe and elbows to the appliance adaptor.

Step 3. With the pipe in the correct position and attached to the replace, mark the wall for a hole as

directed by specied wall thimble dimensions. Cut and frame the hole in the exterior wall where
the vent will be terminated. If the wall being penetrated is made of a non-combustible material

(i.e. masonry or concrete) a minimum 7 1/2” (191mm) hole is acceptable.

Step 4. The vent pipe must extend into the vent cap at least 1¼” (320 mm). Secure the connection

between the vent cap and the pipe by attaching the two (2) sheet metal straps, which extend
from the vent cap assembly to the outer wall of the vent pipe. Bend any remaining portion of

the strap back t owards the vent cap.

Step 5.

Position the horizontal vent termination in the center of the thimble and attach to the exterior

wall with the four screws provided. The arrow on the vent termination must be pointing up. Run
a bead of high-temp silicone around the edges of the vent cap to make a seal with the wall.

Ensure the proper clearances to combustibles have been maintained.

VeRticaL teRmination:

Step 1. Check “InItIal InstallatIon - VentInG

clearances” for required clearances to

combustibles when passing through
ceilings, walls, roofs, enclosures, attic
rafters, or other nearby combustible

surfaces. Do not pack air spaces with

insulation.

Step 2. Set the replace in the desired location.

Drop a plumb bob down from the
ceiling to the replace ue exit and

mark t he location where the vent will

penetrate the ceiling. Drill a small hole
at this point. Next, drop a plumb bob

from the roof to t he hole and mark the
spot where the vent will penetrate the

roof. Determine if ceiling joists, roof

rafters, or other framing will obstruct
the venting system. Relocate the

replace or offset the venting to avoid

cutt ing load bearing members.

Step 4.

To determine the lengt h of pipe required, measure room height, ceiling thickness, and vertical

rise in an attic or second story. Firestops are required at each oor level beyond the rst oor
ceiling support/wall thimble cover or cathedral ceiling support box. If an offset is required to
avoid obstructions, use a pair of 45 degree elbows. For proper support, use elbow straps with

offsets. Use wall straps for long vert ical runs. Attic insulation shield is required in attic.

Measure roof pitch. Select the proper ashing and storm collar and determine the height above

the roof (see Figure 47). A non-corrosive pipe material must be used for all exterior pipe
lengths. Seal nail heads with silicone.
