• • • The installation must conform with local codes or, in the absence of local codes with the National Fuel Gas Code, ANSI Z223.1. • The appliance and its individual shut-off valve must be disconnected from the gas supply piping system while performing any tests of the gas supply piping system at pressures in excess of ... psig. • The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ... psig. • Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids. • Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water. • Input ratings are shown in BTU per hour and are for elevations up to 2,000 feet. Do not install this appliance at an elevation above 2,000 feet unless the gas supply has been derated for that elevation. Consult your local gas supplier. (If the gas supply has not been derated, the burner orifice must be derated at the rate of 4% for each 100 feet above sea level). • Ensure that the appliance is clean when operating. Excessive dust accumulation on the burner and/or logs will increase the amount of carbon monoxide formation and could lead to the formation of soot, carbon monoxide poisoning and sickness or 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 Institute, Inc. (1430 Broadway, New York, NY, 10018) or National Fire Protection Association, Inc. (Batterymarch Park, Quincy, MA, 02269). State or local codes may only allow operation of this appliance (manual version only) in a vented configuration. Check your state or local codes. Seller of unvented propane or natural gas- fired supplemental room heaters shall provide to each purchaser a copy of 527 CMR 30 upon sale of the unit. Serene Heat Gas Log appliances are certified by OMNI-Test Laboratories to ANSI Z21.11.2 unvented room heaters standard. These gas log appliances may be used as a space heat source for a room in conjunction with an approved unvented firebox. Additionally, these units are design certified by OMNI-Test Laboratories to ANSI 21.60 as a vented gas log set. As such, these units may be used as a vented gas log set in any wood-burning fireplace that has been properly constructed to code, and in the case of factory built fireplaces, installed in compliance with manufacturers listing and installation instruction. Use of the log sets covered by this manual in a properly vented wood-burning fireplace which has had the damper blocked open as detailed below, preclude consideration of the combustion and ventilation air and clearance to combustible restrictions discussed herein. When local codes require the damper to be fixed open, a damper stop must be installed to prevent full closure of the fireplace damper and provide a minimum 29 square inch flue opening at all times. If damper clamp is not available, the damper may be fixed open in the following manner. Drill a hole in the end of the damper. Screw in a bolt of sufficient size and adjust to provide the minimum 29 square inches of flue opening. COMBUSTION AND VENTILATION AIR These heaters shall not be installed in a confined space. The heater may be located in unusually tight construction provided the space is unconfined, or if confined, is provided with two permanent openings communicating 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 confined 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 communicating directly with the space in which the appliances are installed, through openings not furnished with doors, are considered a part of the unconfined space. Unusually tight construction is defined as construction 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 operable 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, ...
