different altitudes and venting arrangements. Start the pilot and then the burner. Make sure the pilot
ame is burning normally and none of the burner ports are plugged. Let the replace burn for roughly
fteen minutes and then examine the ames, compare the ames to Figure 53.
The ideal ame will be blue at the base and light orange above. The ames should be of medium height.
If the ames look like this, no venturi adjustment is needed. If the ames are fairly short and mostly blue,
Open/
More Air
Close/
Less Air
Air Shutter
the replace is getting too much air. Therefore,
the air shutter should be closed (moved right)
slightly until the correct ames are achieved.
Flames that are very orange, with tall, dark,
stringy tips, are not getting enough air. Open
(move left) the venturi until the ames clean up.
If the venturi is opened, or closed all the way, and
the correct ames cannot be attained, turn off
the gas and contact your dealer.

BURNER LIGHTING:

Maintenance And Service
ROUTINE MAINTENANCE:
At least once a year, run through the following procedures to ensure the system is clean and working
properly. 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 on the tips.
Warning: Clearances must be sufcient to allow access for maintenance and service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specically approved with this appliance may result in property damage, personal injury, or void your
warranty.
The venting system must be periodically examined; it is recommended the examination is done by a
qualied agency.
CLEANING THE GLASS:
When the replace is off and has cooled, remove the face of the replace along with the glass.
See 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. However, this condensation can allow dust and lint to cling to the glass surface. Initial
paint curing of the appliance may leave a slight lm behind the glass, a temporary problem. The glass
will need cleaning about two weeks after installation. Use a mild glass cleaner and a soft cloth;
abrasive cleaners will damage the glass and plated surfaces. Depending on the amount of use,
the glass should require cleaning no more than two or three times a season. In some instances, a white
lm may form on the glass, caused by gas impurities. The white lm can be removed by using ceramic
polish. Do not clean the glass when it is hot.
CLEANING THE FIREBOX:
Remove the logs carefully, as they are very fragile. Gently remove all the coal chunks and rock wool and
place on a paper towel. Vacuum the bottom of the rebox thoroughly. Carefully clean any dust off the
logs and remove any lint from the burner and pilot. At this time, inspect the burner pan for cracking or
severe warping. If a problem is suspected, contact your dealer. Check the logs for deterioration or large
amounts of soot; a small amount on the bottom side of the logs is normal. Replace the logs and embers
as in the LOG SET AND EMBER INSTALLATION section. If new/more rock wool 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 - COMPONENTS). Wear gloves when handling damaged glass door
assembly to prevent personal injury. When the glass door assembly is being transported, it must be
wrapped in newsprint and tape and/or a strong plastic bag. Do not operate your replace with the glass
front removed, cracked or broken. Removal and replacement of the glass from the door must be done
by a licensed or qualied service person. The glass must be purchased from an ENVIRO dealer.
Substitute materials will void the warranty.

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 unpacked/unwrapped 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.
GLASS DOOR REMOVAL:
In order to install the log set, and
for regular cleaning, the glass door
must be removed. There are two
(2) door latch mechanisms under
and two (2) above the glass door
shown in Figure 6 & 7. Each latch
has two (2) nger grooves, use
these to pull the mechanisms
straight out. When the latches
are unhooked, lift the door up and
forward off the unit.
To replace the glass door, simply
reverse the above procedure.
Warning: Do not touch or attempt
to remove the glass if the replace
is not completely cold.
WARNING: Never operate
the replace with the glass
removed.

INTRODUCTION:
This section of the owner’s manual is for the use of qualied technicians only. Fireplace placement,
hearths, facing, mantles, and venting terminations will be covered, as well as the gas and electric
systems. There are several installation safety guidelines that must be adhered to. Please carefully read
the safety precautions at the front of this manual.
Warning: Clearances must be sufcient to allow access for maintenance and service.
VENT HEAT SHIELD SET-UP:
The vent shield must be set-up prior to the Retreat
being installed.
1. The heat shield is shipped at (see Figure 9). The
at shield must be bent up 90° to the top of the
unit (see Figure 10).
2. Bend the two (2) side aps 45° back around the
vent (see Figure 11).

The replace can be located along a wall,
raised or at oor level, or in a corner. There
are specic framing measurements for each
situation. The basic opening should have the
dimensions shown in Figure 12 and Table 2.
Refer to Figure 1 and Table 3 for the placement
of the gas and electrical inlets. When the basic
framing is done and the unit is installed the
three (3) top pieces of the framing should be
installed Figure 13.

PLACEMENT AND FRAMING:
The replace must have a strong and level surface to be placed on. The surface should be made of wood
or a non-combustible material, not carpet.
The framing boards may touch the top, side and back standoffs, but no insulation or other material
can be placed between the frame and the standoffs.

Initial Installation
QUALIFIED INSTALLERS ONLY
The gas line,  inch NPT, can be brought to either the right side, the left side, or the bottom of
the replace. If this set up is inconvenient, the electrical wire and the gas line conguration can be
reversed.
The location should be chosen so the replace must be at least 36 inches (91.4 cm) from drapes, doors
and other combustibles. The framed opening should also be a minimum of 6.5 inches (16.5 cm) from the
nearest perpendicular wall (sidewall to the edge of the opening).
The Retreat is designed so it can be installed at oor level without a required hearth.
CORNER INSTALLATION:
RAISED FIREPLACES AND HEARTHS:
Even though the Retreat can be installed at oor level without a hearth, there are a few options with
raised replaces: raised with a raised hearth (Figure 15), raised with a oor level hearth (Figure 16), or
raised with no hearth (Figure 17). If the replace is raised, it cannot be placed within 43 inches (110.5
cm) of the ceiling. When installing a raised replace, it is imperative that the support stand is strong
enough to hold the weight of the replace (up to 200lb [90.7Kg]) and venting.

INSTALLATION INSTRUCTIONS:
1. Plan your installation and clearances to combustibles. Decide on a location for the unit that will meet
the clearances noted in the venting section, and any or all local code requirements.
2. Set the appliance in the desired location. Determine if any wall studs, electrical wiring, or plumbing
pipes are in the way of the venting system as it passes through the exterior wall. The replace location
should be adjusted if obstructions are found in the wall.
3. Project a line from the center point of the ue outlet upward and outward to the desired ue outlet
location on the exterior wall. Using this center point, scribe a 10” (25.4 cm) hole or square on the wall.
Cut the hole from the interior through the exterior wall surfaces.
Please read and understand these instructions before installing. Failure to follow
these instructions carefully could cause property damage or personal injury.
