Have replace serviced. Some people are

more affected by carbon monoxide than oth-

ers. These include pregnant women, people

with heart or lung disease or anemia, those

under the inuence of alcohol and those at

high altitudes.

propane/LP gases are odorless. An odor-

making agent is added to the gas. The odor

helps you detect a gas leak. However, the

odor added to the gas can fade. Gas may be

present even though no odor exists.

Make certain you read and understand all

warnings. Keep this manual for reference. It

is your guide to safe and proper operation of

this replace.

11. Do not run replace

• where ammable liquids or vapors are

used or stored.

• under dusty conditions.

12. Do not use this replace to cook food or

burn paper or other objects.

13. Never place any objects in the replace

or on logs.

14. Do not use replace if any part has been

under water. Immediately call a qualied

service technician to inspect the room

replace and to replace any part of the

control system and any gas control which

has been under water.

15. Turn off and unplug fireplace and let

cool before servicing. Only a qualied

service person should service and repair

replace.

16. Operating replace above elevations of

4,500 feet could cause pilot outage.

17. Do not operate fireplace if any log is

broken. Do not operate replace if a log

is chipped (dime-sized or larger).

18. To prevent performance problems, do

not use propane/LP fuel tank of less than

100 bs. capacity (propane/LP units only).

19. Provide adequate clearances around air

openings.

5. Do not use this replace as a wood-burn-

ing replace. Use only the logs provided

with the replace.

6. Do not add extra logs or ornaments such

as pine cones, vermiculite or rock wool.

Usingthese addeditemscan causesoot-

ing. Do not add lava rock around base.

Rock and debris could fall into the control

area of replace.

7. This replace is designed to be smoke-

less. If logs ever appear to smoke, turn

off replace and call a qualied service

person. Note: During initial operation,

slightsmoking couldoccurdue tologcur-

ing and replace burning manufacturing

residues.

8. To prevent the creation of soot, follow the

instructionsinCleaning andMaintenance,

page 22.

9. Before using furniture polish, wax, carpet

cleaner or similar products, turn heater off. If

heated, the vapors from these products may

create a white powder residue within burner

box or on adjacent walls or furniture.

10. This replace needs fresh air ventilation to

run properly. This replace has an Oxygen

Depletion Sensing (ODS) safety shutoff

system. The ODS shuts down the re-

place if not enough fresh air is available.

See Air for Combustion and Ventilation,

page 7. If replace keeps shutting off, see

Troubleshooting, page 23.

ASSEMBLING AND INSTALLING TRIM

1. Remove packaging from 3 pieces of trim.

2. Locate 2 adjusting plates with set screws

and 2 shims in hardware packet.

3. Align shim under adjusting plate as shown

in Figure 4.

4. Slide one end of adjusting plate/shim

in slot on mitered edge of top trim (see

Figure 4).

5. Slide other end of adjusting plate/shim

in slot on mitered edge of side trim (see

Figure 4).

6. While rmly holding edges of trim together,

tighten both set screws on adjusting plate

with slotted screwdriver.

7. Repeat steps 2 through 6 or other corner.

8. Trim should be attached only after your

fireplace has been installed into the

mantel or wall. To install trim, rmly snap

trim assembly on shoulder screws (see

Figure 5). Shoulder screws are located

on replace cabinet.

Today’s homes are built more energy efcient

than ever. New materials, increased insulation

and new construction methods help reduce

heat loss in homes. Home owners weather

strip and caulk around windows and doors

to keep the cold air out and the warm air in.

During heating months, home owners want

their homes as airtight as possible.

While it is good to make your home energy

efcient, your home needs to breathe. Fresh

air must enter your home.All fuel-burning ap-

pliancesneedfreshair forpropercombustion

and ventilation.

Exhaust fans, replaces, clothes dryers and

fuel burning appliances draw air from the

house to operate. You must provide adequate

fresh air for these appliances. This will insure

proper venting of vented fuel-burning appli-

ances.

Example: Space size 20 ft. (length) x 16 ft.

If additional ventilation to adjoining room

is supplied with grills or openings, add the

* Do not include direct-vent gas appliances.

Direct-vent draws combustion air from the

outdoors and vents to the outdoors.

Example:

Gas water heater ____________Btu/Hr

Vent-free heater +___________Btu/Hr

Total =___________Btu/Hr

4. Compare the maximum Btu/Hr the space

can support with the actual amount of Btu/

AIR FOR COMBUSTION AND VENTILATION

Continued

Example: 51,200 Btu/Hr (maximum the

space can support)

56,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the above example is a conned

space because the actual Btu/Hr used is more

than the maximum Btu/Hr the space can sup-

port. You must provide additional fresh air. Your

options are as follows:

A. Rework worksheet, adding the space of an

adjoining room. If the extra space provides

an unconned space, remove door to adjoin-

ing room or add ventilation grills between

rooms. See Ventilation Air From Inside

Building,.

B. Vent room directly to the outdoors. See

Ventilation Air From Outdoors, page 9.

C. Install a lower Btu/Hr replace, if lower Btu/

Hr size makes room unconned.

If the actual Btu/Hr used is less than the

maximum Btu/Hr the space can support, the

space is an unconned space. You will need

no additional fresh air ventilation.

adjoining unconned space, you must provide

two permanent openings: one within 12" of

the ceiling and one within 12" of the oor

on the wall connecting the two spaces (see

options 1 and 2, Figure 6, page 9). You can

also remove door into adjoining room (see

Note: Your replace is designed to be used in

zero clearance installations. Wall or framing

material can be placed directly against any ex-

terior surface of your replace, except where

standoff spacers are integrally attached. If

standoff spacers are attached to your re-

place, these spacers can be placed directly

against wall or framing materials.

Use the dimensions shown for rough openings

to create the easiest installation (see Built-In

Fireplace Installation, page 11).

Use the correct gas type (natural or propane/

INSTALLATION ITEMS

Before installing replace, make sure you

have the items listed below.

• external regulator - propane/LP only (sup-

plied by installer)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• test gauge connection *

• ground joint union

• sediment trap

• tee joint

• pipe wrench

* A CSA design-certied equipment shutoff

valve with 1/8" NPT tap is an acceptable al-

ternative to test gauge connection. Purchase

the optional CSA design-certied equipment

shutoff valve from your dealer.

Note: If desired, purchase a four-sided brass

trim kit for built-in installations. See Acces-
