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 or personal injury.

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

qualied agency.

gLass DooR RemoVaL:

Turn unit off and wait until the appliance has cooled down. Remove the decorative fascia or clip-on bay window by lifting it up

and removing it from the slots in the body of the unit.

Undo the two (2)

the glass and frame, being careful that the glass does not fall out of

the door frame assembly. Install in the reverse order. Ensure the door is properly fastened after cleaning before attempting

to re-light the appliance.

Figure 6: Top bolts for glass door.

cLeaning the gLass:

When the replace 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 replaces. However, this condensation can allow dust and lint to cling to the glass surface. 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 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. 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 embers 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 the 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

seconDary InstallatIon - log set anD ember InstallatIon section. If new/more embers and rock wool are required, contact your nearest ENVIRO dealer.

Maintenance And Service

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. 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 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. No substitute materials

are allowed.

cLeaning the painteD suRFaces:

Painted surfaces should be periodically wiped with a damp cloth when the unit is cool.

buRneR anD bLoweR RemoVaL:

1. Turn the unit off, remove the glass door (see maIntenance anD serVIce - glass Door remoVal) and the log set. Caution: Bleed lines before lighting and light pilot with door open.

2. Remove the burner tray top by removing the two (2) T-20 screws located in the center of the burner tray (see Figure 7). Slide tray to the left and lift out.

3. Remove brick panels (see seconDary InstallatIon - brIck panels InstallatIon).

4. Remove the surround panel by lifting it straight up and then out to free it from the body of the unit.

5. Turn the gas supply off and remove gas connection and disconnect the wiring from the side of the

appliance.

6. Remove the three (3) T-20 screws that hold the air deector in place on the back rewall (see Figure

WARNING: This appliance has been designed to draw room air for proper heat circulation from the sides of the unit. Blocking or modifying the louvers in any way can create hazardous

situations.

The vent length for the EG31 must be between 8ft (2.44 m) and 25ft (7.62 m).

This model is vented with TWO (2) 3” aluminum or stainless steel ex vent leading into a co-linear to coaxial vent adaptor and using a Simpson Dura Vent vertical termination cap. The ue collars of this model will t inside of standard 3” vent and may be fastened directly to the vent. The Exhaust vent is in the center of the ue connector. The Air Intake is on the left side of the vent collar plate (this outlet is not in

the center it is off to one side of the vent collar plate.)

Check periodically that the vents are unrestricted. Also ensure that all direct vent pipes have been

properly sealed and installed after routine inspection or cleaning. The air intake and exhaust pipes must be installed in the correct locations on the removable draft hood connector.

DiRect Vent RestRictoR Ring:

DIRECT VENT ONLY: The maximum vertical vent

height for a direct vent installation is 25 feet (7.62 m). Use the vent restrictor ring for installations above 15 feet (4.57 m). See Figure 14 for installation

An approved chimney liner and rain cap must be used. A throat connector or ashing must be installed to

ensure a tight seal, top performance, safety and efciency. Carefully follow the manufacturer’s instructions that accompany the chimney liner kit. Use double walled aluminum ex vent (3” ex conversion piece and 4”x 6 5/8” cap) from any of the following approved products; Simpson Dura-Vent (Direct Vent GS) or (ICC Excel Direct). If necessary, remove the vent collar plate from the top of the insert and connect it securely

to the liner with sheet metal screws.

Check for any tears in the liner at this point. IMPORTANT: The screws that hold the vent collar plate in its

approved position must be installed.

NOTE: If the EG31 unit is pulled out of its installation, and the vent air intake system is disconnected

for any reason, ensure that the vent-air intake pipes are re-sealed with high-temperature sealant and reconnected with three (3) sheet metal screws evenly spaced.

The placement of the logs is not arbitrary. If they are positioned incorrectly, the ames can be “pinched”

and will not burn correctly. The burner comes with placement pins and rest areas, which make alignment

easier. Using Figures 34 to 39, carefully set the logs in place.

NOTE: The logs are fragile and should

be handled with care.

Place the rear log on the two back placement

pins.

Install the left front log on the left placement

pin with the narrow end of the log resting on the rectangular rest area.

Figure 34: EG31 burner.

Install the right front log on the right

placement pin with the narrow end of the log resting on the rectangular rest area. The last two logs should meet tip to tip on the rest area.

One end of the big log twig will rest

on the pin on the right log and the other will lay within the left rest area.

The small log twig should be placed so it sit completely within the right rest area.

Once the logs are in place the embers

can be placed lightly between the

logs. Bags of ceramic ber embers

and rock wool are provided. The

ceramic ber comes in chunks that are about 2”-4” (5-10cm) long. Break these roughly in half and

place them irregularly around the burner. When there is a sparse but even layer of embers, spread the

rock wool in the same manner. DO NOT pack this ember material as this

could create an unsafe condition. The pieces should be lightly place so they don’t completely block any of

the tiny ports. DO NOT allow any of

the embers to rest against the pilot assembly.
