1. This gas log set is only to be installed and burned in a fully vented fireplace with a fully functional damper and
chimney that is free of any obstructions. The fireplace must be constructed of non-combustible materials and
approved to burn wood. WARNING: Do not burn wood or other material in any fireplace fitted with a gas

log set.

2. To operate this gas log set, the fireplace damper must be fully opened and locked.

3. The smallest or minimum dimension of the chimney flue must be 8 inches in diameter. Do not use an Energy
Efiicient Gas Log Set if it is smaller than 8 inches. Do not use an Energy Efiicient Gas Log Set if fumes from the
burner emerge into the room when the damper is fully open. This indicates that there is not adequate draft for our
log set and the gas log set must not be used until fireplace draft is corrected.

4. This appliance must be installed with a Damper Stop Clamp (Part #14). When operating this gas log set, the flue
damper must be fully open.

WARNING: Improper use or installation may cause Carbon Monoxide Poisoning. Carbon Monoxide, which is
an odorless and colorless gas, is a by-product of combustion. Caution must be taken to insure the fireplace is
properly vented when logs are in use. To avoid having potentially dangerous fumes enter the living area, be sure
the chimney is drawing properly and has sufficient draft.

5. A fireplace screen must be in place when operating this gas log set. This screen shall have an opening(s) for the
introduction of combustion air. If the fireplace has glass doors, operate this gas set with the doors fully opened.

6. The nominal inlet gas pressure for this appliance is 7" water column for natural gas.

7. This gas log appliance and its individual shutoff valve must be disconnected from the gas supply piping system
during any pressure testing at pressures in excess of 1/2 PSIG.

This appliance must also be disconnected from the gas supply system by closing its individual manual shutoff valve
during any pressure testing at pressures equal to or less than 1/2 PSIG.

PART NO. 14

FIREPLACE PREPARATION

A. Professionally clean chimney and fireplace floor of any

combustible material to limit the smell from the system.

B. Open fireplace damper fully and install Damper Stop Clamp

with 1/4 x 2" set screw (Part #14). This clamp is designed to
allow any pilot combustion by-products to vent (See Figure 2.)
Should the Damper Stop Clamp supplied not fit, a permanent
damper stop clamp must be installed that will keep the damper
open at a distance of not less than 1 1/2". Damper must be in
full open position anytime this unit is in operation.

C. Prior to connecting the gas log set, make sure that the gas

supply to the fireplace is completely shut off.

Figure 2. Damper stop clamp

Installation of this Energy Efficient Gas Log Set and provisions for combustion and ventilation air

must conform with the National Fuel Gas Code ANSI Z21-84 and applicable local codes.

D. Prefabricated fireplace: Refer to the manufacturers fireplace instruction manual for specific information

regarding the running of a gas line into that particular model. A typical prefab installation involves the insertion
of a 1/2" gas pipe through the gas line tube provided by each manufacturer from outside the fireplace. The
knockout on the inside of the fireplace is removed as the gas pipe is punched through the fireplace.

E. Masonry fireplaces: A 1/2" gas supply line must be provided to the firebox. Most installations require drilling an

access hole through the masonry wall. The supply line should be secured and sealed by mortar within the access
hole. The supply line should also have an on-off valve either in the wall or inside the fireplace. (See Figure 4.)

GAS LOG INSTALLATION

(See Figure 1 Parts List as a guide to reference part numbers.)

BURNER PAN INSTALLATION
NOTE: Use pipe compound on all male threads to seal joints.

A. Determine if the fireplace has a right or left-hand gas line feed. The circular

“dimpled” hole covering must be knocked out on the appropriate (right or
left) side of the burner pan. NOTE: Brace pan on workbench when removing
burner knockout. Strike knockout with nailpunch for easy removal.

B. Locate 3/8" locknut (Part #12 ) and fasten it to the 3/8" brass orifice elbow

(Part #11). Do not fasten the locknut on the “flared” end.

C. Slide the 3/4" burner support spacer (Part #10) over the Dual Burner Bar

(Part #9) and move spacer to opposite corner of the gas intake connection
(See Figure 5).

D. Secure the intake end of the Dual burner bar (Part #9) to the burner pan

(Part #8) through the knockout hole selected (right or left hand) with the
3/8" brass orifice elbow (Part #11) and 3/8" locknut previously assembled in
Step B (See Figure 6).

Figure 5 - Burner bar placement

E. Tighten elbow until firmly attached to the Dual burner bar. Then, firmly

tighten the attached locknut on the elbow to seal the burner bar to the wall
of the burner pan.

CONNECTING GAS SUPPLY TO BURNER ASSEMBLY

(If a Safety Pilot Kit is to be used, please refer to separate installation instructions.) These instructions refer to
Natural Gas applications installed without a Safety Pilot Kit. LP/NG Safety Pilot Kit available at your local store.

A. Place burner pan assembly in the center of the fireplace.

B. Attach brass 3/8" Flared to 1/2" gas valve (Part #13) to the 1/2" gas supply stub.

C. Attach 3/8" flared tubing (part #15) to burner pan assembly. Attach opposite end to gas supply line by carefully

bending the flared tubing as needed to make the connection. Avoid kinking the flared tubing while bending. If
tubing must be cut, use a tube cutter. Flare the cut end of the tube with a flaring tool.

NOTE: A good method of bending the tube is to fill it with sand, bending the tube as needed to make the

connection. This method will eliminate kinking in the line. Once the tube is in the desired configuration for
hookup, be sure to empty the tube completely of any sand before tube is connected to the gas supply line
and the burner.

D. Be certain all connections are tight and use pipe compound on all male threads to seal joints. Test all connections

with a soapy water solution with the gas supply turned on. If bubbles appear on any connection, retighten and
retest. Once it is determined there are no leaks whatsoever, turn off gas supply and move to next assembly step.

GRANULE, EMBER AND GRATE PLACEMENT

A. Spread granules (Part #16) over the installed burner pan. Granules

should be sloped to the same angle as the burner pan filling the entire
pan. (See Figure 7A).

B. Spread glowing embers (Part #17) evenly over the top of the granules

covering the entire surface area, concentrating on the front and sides
of the burner pan for the most realistic burning effect.

C. Place log grate (Part #7) over the burner pan aligning as shown

(See Figure 7B).

Figure 7 (A & B) ­Granule and Grate Placement

D. Attach back log Standoffs (Part #18) to the back part of the grate (See Figure 7B).

NOTE: A hammer may be used to tap the back log standoffs in place. It may be necessary to squeeze the back log

standoffs with pliers after attaching to the grate

LOG PLACEMENT

(Part Numbers 1 through 6)

A. Place longest log in the front of the grate.

B. Place the second longest log on the back log standoffs towards the back of the grate. Allow approximately 2" of

separation of the bottom logs to allow for proper flame combustion.

C. Arrange remaining logs on top of the two base logs. Top logs can be rearranged to achieve the desired

flame pattern.

LIGHTING YOUR GAS LOG SET

(Manual valve only)

A. Open chimney flue damper to the full open position.

B. Be sure gas supply is shut off.

C. Lay match on top of embers and granules near gas burner input.

Do not hold match in hand (See Figure 8).

D. With match burning, slowly turn on gas.

MAINTENANCE

Very little maintenance is required. The carbon deposit resulting from combustion is natural and adds to the realistic
appearance of the set. If carbon becomes excessive it can be lightly brushed or vacuumed away.

TROUBLE SHOOTING

Problem Cause Corrective Action

1. No Ignition valve not on turn valve on

gas line not clear inspect supply lines for tube kinks or obstructions

2. Inadequate Flame valve partially closed open valve fully
