Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning are similar to the flu with headaches, dizziness and/or nausea. If you have these signs, obtain fresh air im- mediately. Turn off the gas supply to the heater and have the Unvented Gas Heater serviced as it may not be operating correctly.
•Due to high temperatures, the heater should be located out of traffic and away from furniture and draperies.
•Children and adults should be alerted to the hazard of high surface temperatures and should stay away to avoid burns or clothing ignition.
•Young children should be carefully supervised when they are in the same room with the heater.
•Do not place clothing or other flammable material on or near the heater for the purpose of drying.
•Installation and repair should be done by a qualified service person. The heater should be inspected before use and at least annually by a professionalserviceperson. More frequentclean- ing may be required due to excessive lint from carpeting, bedding material, etc. It is important that control compartments, burners and circulat- ing air passageways of the heater be kept clean.
•Allow the heater to cool before servicing. Always shut off any electricity or gas to the heater while performing service work.
•Do not install the VFST and VFPF series heaters in a bedroom or bathroom.
•The installation must conform with local codes or, in the absence of local codes with the National Fuel Gas Code, ANSI Z223.1.
•The heater and its individual
•Any safety screen or guard removed for servicing the heater must be replaced prior to operating the heater.
•The heater must be isolated from the gas supply piping system by closing its individual manual
•Keep heater area clear and free from com- bustible materials, gasoline and other flam- mable vapors and liquids.
•Do not use these appliances if any part has been under water. Immediately call a qualified professional service technician to inspect the appliance and to replace any parts of the control system and any gas control which have been under water.
•Test gage connections are provided on the front of the gas control valve (identified A for the manifold side and E for inlet pressure).
•Input ratings are shown in BTU per hour and are for elevations up to 7,000 feet. Operating heater above elevations of 7,000 feet may cause ODS pilot outage.
•Ensure that the heater is clean when operat- ing. Excessive dust accumulation on the burner and logs will increase the amount of carbon monoxide formation and could lead to carbon monoxide poisoning and death.
CODES
Adhere to all local codes or in their absence the latest edition of The National Fuel Gas Code ANSI Z223.1 or NFPA54 which can be obtained from The American National Standards Insti- tute, Inc. (1430 Broadway, New York, NY, 10018) or National Fire Protection Association, Inc. (Batterymarch Park, Quincy, MA, 02269).
Massachusetts And New York Require- ments
These appliances are approved for installation in the following USA locations listed in the following:
Massachusetts:
These fireplaces are approved for installation in the US state of Massachusetts if the follow- ing additional requirements are met-
•Installation and repair must be done by a plumber or gas fitter licensed in the Common- wealth of Massachusetts.
•The flexible gas line connector used shall not exceed 36 inches (92 centimeters) in length.
•The individual manual
•
•A working smoke detector must be installed in the area where
Seller of unvented propane or natural gas- fired supplemental room heaters shall pro- vide to each purchaser a copy of 527 CMR 30 upon sale of the unit.
New York:
These fireplaces are approved for installation in the US state of New York, but not in New York city.
COMBUSTION AND VENTILATION AIR
These heaters shall not be installed in a con- fined space. The heater may be located in unusually tight construction provided the space is unconfined, or if confined, is pro- vided with two permanent openings commu- nicating directly with an additional room(s) of sufficient volume so that the combined volume of all connected spaces meets the criteria for an unconfined space, (National Fuel Gas Code ANSI Z223.1 (latest edition), Section 5.3). Generally 50 ft 3 per 1,000 BTU input of all operating appliances in the space.
The National Fuel Gas Code defines a con- fined space as a space whose volume is less than 50 ft 3 per 1,000 BTU/Hr (4.8 m3 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 ft 3 per 1,000 BTU/Hr (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicat- ing directly with the space in which the appli- ances are installed, through openings not furnished with doors, are considered a part of the unconfined space.
Unusually tight construction is defined as con- struction where:
a. wall and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating or one perm or less with openings gasketed or sealed, and
b. weather stripping has been added on oper- able windows and doors, and
c. caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall- ceiling joints, between wall panels, at penetra- tions for plumbing, electrical, and gas lines, and at other openings.
Use the following equations to determine if you have a confined or unconfined space.
1.Determine the volume of space — ft 3.
Length x Width x Height = _____ ft 3 (Include adjoining rooms with doorless pas- sageways or ventilation grills between rooms.)
Example: 16' (L) x 16' (W) x 8' (H) = 2048 ft 3
