Vented/Vent-Free Burner and Logs

This is an unvented gas-ﬁred heater. It uses air (oxy-

gen) from the room in which it is installed. Provisions

for adequate combustion and ventilation air must be

provided. Refer to page 8.

WARNING: If not installed, operated and maintained

in accordance with the manufacturer's instructions,

this product could expose you to substances in fuel or

from fuel combustion which can cause death or seri-

ous illness.

WATER VAPOR: A BY-PRODUCT OF UN-VENTED

ROOM HEATERS

Water vapor is a by-product of gas combustion. An

unvented room heater produces approximately one (1)

ounce (30ml) of water for every 1,000 BTU's (.3KW's)

of gas input per hour. Refer to page 6.

This appliance may be installed in an aftermarket

permanently located, manufactured (mobile) home,

where not prohibited by local codes.

This appliance is only for use with the type of gas

indicated on the rating plate. This appliance is not

convertible for use with other gases.

— Do not store or use gasoline or other ﬂammable

vapors and liquids in the vicinity of this or any

other appliance.

— WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electrical switch; do not use

any phone in your building.

• Immediately call your gas supplier from a

neighbor’s phone. Follow the gas supplier’s

instructions.

• If you cannot reach your gas supplier, call the

ﬁre department.

GENERAL INFORMATION This is an unvented gas-ﬁred heater. It uses air (oxygen) from the room in which it is installed. Provisions for adequate combustion and ventilation air must be provided. Keep room area clear and free from combustible materials, gasoline and other ﬂammable vapors and liquids. Unvented gas heaters are a supplemental zone heater. They are not intended to be a primary heating appliance.
PAGE 8
PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR This heater shall not be installed in a conﬁned space unless provisions are provided for adequate combustion and ventilation air. The National Fuel Gas Code deﬁnes a conﬁned space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8m3 per kw) of the aggregate input rating of all appliances installed in that space and an unconﬁned space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.

CLEARANCES (continued) Sidewall & Ceiling Clearances (Figure 3) 18”, 24”, 30” Log Non-Combustible Material Distance Requirements for Safe Installation 12" or more Non-combustible material Less than 12" Non-combustible material must be extended to at least 8" with the installation of the optional ﬁreplace hood. If you cannot extend non-combustible material at least 8", you must operate heater with ﬂue damper open.
PAGE 10
COMBUSTIBLE MATERIAL Do not attach combustible material to the mantel of your ﬁreplace. This is a ﬁre hazard. No greeting card, stockings or ornamentation of any type should be placed on or attached to the ﬁreplace. This is a heating appliance. The ﬂow of heat can ignite combustibles. Figure 7 Figure 8 FIREPLACE PREPARATION • Turn off gas supply to ﬁreplace or ﬁrebox. • Have the ﬁreplace ﬂoor and chimney professionally cleaned to remove ashes, soot, creosote or other obstructions.
PAGE 11
INSTALLING AS A VENTED APPLIANCE Notice (Damper Clamp Installation) When installing your log set as a vented installation the damper clamp must be used. When installing your log set as a vent-free installation the damper clamp can be used to eliminate the potential for odors when burning the logs for the ﬁrst time. Installing Damper Clamp (Figure 9) Remove all ashes or other debris from the ﬁreplace.

VFD(R,T,M)(18,24) & VFDR18LB10 LOG PLACEMENT (5 LOG SET) Before you begin: if you are installing logs onto the VFD(R,T,M)18 or VFD(R,T,M)24 models, this burner assembly is supplied with a set of ﬁve ceramic ﬁber logs. Do not handle these logs with your bare hands! Always wear gloves to prevent skin irritation from ceramic ﬁbers. After handling logs, wash your hands gently with soap and water to remove any traces of ﬁbers.
PAGE 14
VFD(R,T,M)30 LOG PLACEMENT (7 LOG SET) Before you begin: If you are installing logs onto the VFD(R,T,M)30 model, this burner assembly place is supplied with a set of seven ceramic ﬁber logs. Do not handle these logs with your bare hands. Always wear gloves to prevent skin irritation from ceramic ﬁbers. After handling logs, wash your hands gently with soap and water to remove any traces of ﬁber. The positioning of logs is critical to safe and clean operation of this burner assembly.

OPERATION INSTRUCTIONS/FLAME APPEARANCE Flames from the pilot (rear right back side of the pan burner) as well as the main ﬂame should be visually checked as the log set is installed. PILOT ASSEMBLY BURNER TUBE In normal operation at full rate, the ﬂame appearance should be sets of yellow ﬂames above the rear burner section, and shorter blue ﬂames with glowing embers on the front burner section. NOTE: all ﬂames will be random by design, ﬂame height will go up and down.

WIRING - VFDR MODELS ONLY burner assembly. Thermostats are not approved on vented decorative appliances. On circulating vent-free ﬁrebox, install remote control receiver behind bottom louver. Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. Refer to remote control installation and operating instructions for more details on remote control.

VFDR(18,24,30)LB LIGHTING INSTRUCTIONS FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a ﬁre or explosion may result causing property damage, personal injury or loss of life. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING, smell all around the appliance area for gas. Be sure to smell next to the ﬂoor because some gas is heavier than air and will settle on the ﬂoor.

PILOT FLAME CHARACTERISTICS Figures 21 and 22 show a correct pilot ﬂame pattern. The correct ﬂame will be blue and will extend beyond the thermocouple. The ﬂame will surround the thermocouple just below the tip. A slight yellow ﬂame may occur where the pilot ﬂame and main burner ﬂame meet. Figures 23 and 24 show an incorrect pilot ﬂame pattern. The incorrect pilot ﬂame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
PAGE 22
PILOT FLAME CHARACTERISTICS Cleaning and Maintenance/Pilot Oxygen Depletion Sensor Pilot (Figures 25 and 26 ) When the pilot has a large yellow tip ﬂame, clean the Oxygen Depletion Sensor as follows: 1. Clean the ODS pilot by loosening nut B from the pilot tubing. When this procedure is required, grasp nut A with an open end wrench. 2. Blow air pressure through the holes indicated by the arrows. This will blow out foreign materials such as dust, lint and spider webs. Tighten nut B also by grasping nut A.
PAGE 23
TROUBLESHOOTING SYMPTOMS, POSSIBLE CAUSES AND CORRECTIONS 1. When ignitor button is pressed, there is no spark at ODS/ pilot. a. Ignitor electrode positioned wrong - Replace pilot. b. Ignitor electrode is broken - Replace pilot. c. Ignitor electrode not connected to ignitor cable - Reconnect ignitor cable. d. Ignitor cable pinched or wet. Keep ignitor cable dry - Free ignitor cable if pinched by any metal or tubing. e. Broken ignitor cable - Replace ignitor cable. f.
