IMPORTANT: Installation and service must
be performed by a qualified professional
installer, service agency, or the gas supplier.
NOTE: This appliance is only for use with the
type of gas indicated on the rating plate.
Solid-fuels shall not be burned in a fireplace
where a decorative appliance is installed.
This Hargrove vented gas log set is to be
installed only in a solid-fuel burning fireplace
with a working flue and constructed of
noncombustible material. The installation,
including provisions for combustion and
ventilation air must conform to the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
CSA B149.1, Natural Gas and Propane
Installation Code, and applicable local building
code. A damper clamp is included to maintain
the minimum permanent vent opening and to
prevent full closure of the damper blade. The
gas log set must be burned with the damper
completely open (In the Commonwealth of
Massachusetts the damper must either be
welded in the fully open position or
completely removed) and the chimney free
of any obstructions or restrictions.
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. It is the
home-owners responsibility to assure their
fireplace has adequate draft.

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. It is recommended that adults be present when this gas appliance is operating. It is recommended that this unit
is not left burning when unattended or while anyone is sleeping.
2. Do not use a natural gas set for propane or a propane set for natural gas. If the gas type is not correct. DO NOT
INSTALL. Contact your dealer for immediate assistance.
3. There are 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).
4. Gas log sets must be installed by personnel qualified for installing gas appliances.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. The minimum inlet supply pressure for the purpose of input adjustment is 5.0 inches (natural gas) 11 inches
(propane gas) in water column. The maximum inlet supply pressure is 10.5 inches (natural gas) 13 inches
(propane gas) in water column.
11. 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).
12. The fireplace chimney or venting system should be examined annually and cleaned as required by a qualified
agency.
13. 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.
14. To clean the logs, use a soft dry paintbrush for periodic dusting of the gas fire logs.
15. 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.

BURNER POSITION
GAS CONNECTION
Check that the gas is turned off. Any
remote kits should be installed on the
burner at this point, refer to instructions
with kit for that installation.
The gas supply line should be ½”
inside diameter (ID) up to 30 feet and
¾” for longer distance.
Use the non-whistling flex connector
provided in the accessory kit to
connect the gas supply to the burner
kit. Check to make sure the burner is
in the correct position.
Turn the gas supply on and check
connection for leaks using a soapy
solution.
NOTE- at this point install and
program any remote kits, refer to
the instructions provided with
those kits for installation.
Connect to gas
IMPORTANT: The minimum inlet supply pressure for
the purpose of input adjustment is 5.0 inches (natural
gas) 11 inches (propane gas) in water column. The
maximum inlet supply pressure is 10.5 inches (natural
gas) 13 inches (propane gas) in water column.
BURNER AND GRATE POSITIONING
Check that the gas is turned off.
Center the burner on the fireplace floor.
The burner should be located under the
flue opening.
The grate should be placed over the
burner so the front legs of the grate are
just in front of the burner pipe. The back
legs goes into the slots in the back plate
of the burner.

LIGHTING THE PILOT
Read the lighting instruction plate
attached to the gas valve or located at
the end of these instructions.
Push in gas control knob slightly and turn
clockwise until the knob will not turn any
longer. This is the “OFF” position. The
word off should be at the 12 o’clock
position on the control knob.
Slightly push in on pilot knob and turn
valve to the “PILOT” position. Push the
knob in all the way and hold in.
Immediately light the pilot. (The pilot is
located on the right side of the burner
pan) Continue to hold the knob for at
least 30 seconds after the pilot is lit.
Release the knob and the pilot should
remain lit.
Turn the burner to the “ON”, the pilot
flame should ignite the main burner within
4 seconds.
Carefully check the connections for
leaks using a soapy solution.
NOTE- if the pilot will not stay lit after
several tries turn the control off and
call a technician.
IMPORTANT: 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, adjust using the pilot adjustment screw. The
90 degree pilot should produce 2 flames about 1-1 ½”
in 2 directions. One flame should come towards the
front of the firebox to ignite the burner and the other,
wrapping around the thermocouple to ensure proper
valve operation.
BURNER MEDIA
Fill the burner pan with sand for Natural
gas. For LP no media is needed, just fill
the burner with Glowing Embers. The
media level should be sloped evenly with
the sides of the burner pan. Under filling
will cause uneven flame.
Glowing Embers (Rockwool) are placed
over the media. For best results pinch off
pieces of the rockwool the size of a dime
and feather it out
Test fire the burner once again for
flame distribution, media can be
altered to achieve desired flame
appearance.
GRATE POSITION
FOR YOUR SAFETY: 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
GRATE PLACEMENT
Place the Pedestal Grate over the burner
using the slots as a guide.
The grate should be placed over the burner
so the front legs of the grate are just in front
of the burner pipe.
LOG INSTALLATION
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.
LIMITED LIFETIME 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. Items will be
replaced during this period for the cost of shipping.
VOLCANIC CINDER PLACEMENT
The black volcanic cinders are used to cover the fireplace floor, fittings and tubing around the
burner system. Although not functional, the back cinders act as a picture frame to show off the
glowing embers and yellow flame.
Install the logs based on the installation diagram provided with the logs set, for Radiant Heat
logs it will not be necessary to remove the grate and install the radiant heat bracket (disgard
the radiant heat bracket packaged with Radiant Heat logs).
Once the logs have all been place you can readjust the grate positioning to get desired flame
pattern. When adjusting grate position be careful as the GRATE WILL BE HOT, it might be
necessary to let it cool between adjustments.
