INSTALLER: LEAVE THESE INSTRUCTIONS WITH CONSUMER!

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.

FIREPLACE SIZES

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.
