WARNING: If the information in this
manual is not followed exactly, a fire or
explosion may result causing property
damage, personal injury or loss of life.
It is the homeowner’s responsibility to assure
their fireplace has adequate draft
RECOMMENDED BURN –IN PERIOD
Hargrove gas logs are made of special
refractory materials, which withstand high
temperatures. One characteristic of this
material is retention of moisture.
For this
reason, we recommend burning the logs for
only fifteen minutes during the first burning.
After allowing the logs to cool for at least one
hour, the set can be burned for any length of
time.
WARRANTY
Hargrove gas logs carry a limited lifetime
warranty against breakage in the original
fireplace. Warranty does not include labor.
This warranty is void if excessive handling
after burning causes breakage. All
accessories and metal parts carry a two year
limited warranty in the original fireplace.
Hargrove will replace items during this period
for the cost of shipping.
INSTALLATION AND OPERATION GUIDE FOR
HARGROVE
GAS LOGS
For all models tested through OMNI-Test Laboratories, Inc., to
ANSI Z21.60-2003/CGA 2.26-2003, Decorative Appliance for Installation in Solid-Fuel Burning
Fireplaces. For model number and seal refer to attached nameplate.
Hargrove Manufacturing Corporation uses refractory material to create ceramic logs. Each log is
hand-finished to assure the most realistic, detailed log available. The gas log burner system is
designed to burn like wood, with a smoky flame. For this reason, the gas log set must be burned only
in a fully vented, non-combustible fireplace with the damper completely open and the chimney free
of any obstructions or restrictions. The fireplace must be designed and approved to burn wood.
The realistic yellow flame produces carbon monoxide and soot. Under normal conditions, these
products are exhausted up the chimney. If fumes or soot, from the gas burning, are evident in the
room when the damper is fully open it indicates that the fireplace draft is defective. Do not operate
your gas log set until the fireplace draft is corrected.

IMPORTANT INFORMATION
WARNING: This appliance assembly contains burner orifices specifically for the input gas and
Btu rating. Modifying or failure to use the factory orifice may cause property damage, personal
injury or loss of life.
1. Do not use a natural gas set for a propane or a propane set for natural gas.
2. There a many different local codes for gas fire logs. The installation and the provision for combustion and ventilation
air must conform to local codes and, or in the absence of local codes, with the National Fuel Gas Code ANSI Z223.1 –
(most current revision).
3. Gas log sets must be installed by personnel qualified for installing gas appliances.
4. This appliance must be installed only in a solid-fuel burning fireplace with a working flue and constructed of
noncombustible materials. Solid fuels are not to be burned in a fireplace where a decorative appliance has been
installed.
5. A permanent free opening must be provided by either the fireplace chimney or chimney damper to vent flue gasses.
Any chimney damper must be fixed in a manner, which will maintain the permanent free opening at all times. Use
Table II to determine the minimum permanent free opening based on chimney height and the appliance Btu input
rating. Refer to the Damper Stop section for additional directions.
6. The minimum free opening is based only on two factors; chimney height and Btu input rating. Many other factors affect
the fireplace drafting. It is the homeowner’s responsibility to assure their fireplace has adequate draft. If fumes or soot
from the gas burning are evident in the room when the damper is fully open, it indicates that the fireplace draft is
defective. Do not operate your gas log set until the fireplace draft is corrected. Consult your fireplace specialist.
7. A fireplace screen must be in place when the appliance is operating and, unless other provisions for combustion air are
provided, the screen shall have an opening(s) for introduction of combustion air.
8. When glass fireplace doors are used, always operate gas log set with the doors fully open to allow for proper
combustion air and to keep control valves from overheating.
9. The minimum inlet supply pressure for the purpose of input adjustment is 3.5 inches (natural gas) 8 inches (propane
gas) in water column. The maximum inlet supply pressure is 10.5 inches (natural gas) 13 inches (propane gas) in
water column.
10. The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2 psig (3.5kPa). The appliance must be isolated from
the gas supply piping system by closing its individual manual valve during pressure testing equal to or less than 1/2
psig (3.5kPa).
11. The fireplace chimney or venting system should be examined annually and cleaned as required by a qualified agency.
12. After burning for several hours the logs become fragile and should not be handled. Knocking or rubbing logs can
cause concrete to crumble and is not covered under the warranty.
13. To clean the logs, use a soft dry paintbrush for periodic dusting of the gas fire logs. Special care must be taken to
clean Birch logs. Rubbing will remove soot but will also remove the white pigments.
14. To clean the burner, shut off the gas supply, remove the burner pan media, and vacuum the burner ports. After
cleaning, replace burner pan media and light the pilot according to the lighting instructions.

Each gas log set requires a minimum 16-inch front opening height and minimum 16-inch depth. To
determine the largest set that will fit in a fireplace, the width at the center of the fireplace is the critical
dimension. Table I below indicates the minimum center width for each size set.
*View is looking down on the fireplace floor. To determine center width, add front width and
back width and divide by 2.

DAMPER STOP
Attach the damper stop clamp to the fireplace
damper blade. Position the clamp to prevent
full closure of the fireplace damper blade.
See Figure 1
If the damper stop provided does not fit, the
installer shall install a permanent damper stop
that will keep the damper open to a minimum
of opening as determined in Table II.
EMBER BURNER POSITIONING
1. Turn the gas off.
2. Remove old log lighter, ashes, and all other
materials from the firebox.
3. Center the ember burner on the fireplace floor
with the burner pipe completely visible from the
front. For best results, the ember burner
should be directly under the flue opening with a
minimum of 4” from the front edge of the ember
burner to the fireplace opening.
4. Place the grate over the ember burner so the
front legs of the grate are just in front of the
ember burner pipe. Once the final positioning
is established, mark the burner and grate
position of the floor of the fireplace for
reference points. Remove the grate and
proceed with the gas connection.
See Figure 2
GAS CONNECTION
1. The gas supply line should be 1/2" Inside Diameter (ID) up to 30 feet and 3/4" for longer distance.
2. Use the aluminum connector to connect gas supply to the regulator on the burner assembly. When
bending aluminum tubing use proper bending procedures to avoid kinking the tube. Do not use
corrugated flexible tubing; it may cause a whistling noise.
3. Read lighting instructions. Light pilot and check for leaks using soapy water. These controls are
factory preset and will not normally require additional adjustment of the pilot flame. If field adjustment
of the pilot flame is required, remove the pilot adjust cover screw to expose the adjusting screw. Turn
the adjusting screw clockwise.

Do not use this appliance if any part has been underwater. Immediately call a qualified service
technician to inspect the appliance and to replace any part of the system or gas control, which has
been underwater. Keep this appliance clear and free from combustible materials, gasoline, and
other flammable vapors and liquids.

BURNER PAN MEDIA
1. Fill the burner pan with Sand (Vermiculite if
using LP gas). Sand level should be sloped
evenly with the sides of ember burner. Burner
should be completely full.
2. Light the gas and observe the flame for even
distribution.
3. Embers (Rockwool) are placed over the sand
to simulate glowing embers. For best results
pinch off pieces of the rockwool the size of a
dime and feather it out. Place as much as
desired over the area the gas comes through.
See Figure 3 on previous page
PILOT FLAME
1. The pilot light should be checked periodically to
assure proper flame. On the EB burner pans
the flame should be directly over the back of
the burner pan. The ember burner pan will be
permanently positioned in relation to the grate.
See Figure 4
When turning the main burner on, the pilot
flame should ignite the main gas within 4
seconds without creating a big poof depending
on the gas pressure.
GRATE PLACEMENT
1. Place the Pedestal Grate over the ember
burner using the reference marks made on the
fireplace floor earlier such that the slots in the
grate brackets fit over the back wall of the
burner pan. The ember burner will be
permanently positioned in relation to the grate.
VOLCANIC CINDERS
The black volcanic ciders are used to cover the fireplace floor, fitting and tubing around the burner
system. Although not functional, the black cinders act as a picture frame to show off the glowing
embers and yellow flame.
