The routing of the gas line has to be done to local and / or national codes. 3. When rigid pipe is used an ANSI approved manual shut off and a union must be installed upstream within the fireplace cavity. 4. To ensure the appliance operates reliably install a sediment trap upstream of the appliance within the structures of the piping system. 5. When using propane, a regulator must be used between the tank and the outside wall of the house to ensure the line pressure does not exceed 14” w.c. 6. Check gas connections with a gas detection device to test for leaks in the system. Soapy water mixture can also be used to check for leaks. 7. Once all the gas connections are tested for leaks, start the appliance. Follow the lighting instructions to ensure the appliance is working properly before finishing.

In order to avoid the possibility of exposed insulation or vapour barrier coming in contact with the fireplace body, it is recommended that the walls of the fireplace enclo- sure be 'finished', (i.e. drywall/sheetrock) as would any other outside wall of the home. This will ensure that clearance to combustibles is maintained within the cav- ity. The National Fuel Gas Code, ANSI Z223.1 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (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 cubic feet per 1,000 Btu per hour (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. The GVFL18/24/30 are all rated at 40,000BTUs per hour and therefore requires a minimum unconfined space of 2,000 cubic feet. To determine the volume of the room where the heater is to be installed, multiply the width x the length x the ceiling height of that room measured in feet. If any adjoining rooms are connected by grills or openings such as kitchen passthroughs, etc., the volume of those rooms may be added to the total. Multiply the room volume by 1000 and divide this amount by 50 to determine the maximum Btu/hr that the space can support with adequate combustion and ventilation air. Add the Btu/hr of all fuel burning appliances located within the space such as gas furnace, gas water heater, etc. Do not include direct vent gas appliances which draw their input and output air from and to the outdoors. WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code ANSI Z223.1, Section 5.3 or the applicable local code. figure 1 Room Volume = Length x Width x Height Max BTU/hr = Room Volume x 1000 . 50 If for example, the length of the rooms is 10 feet, the width of Room 1 is 10 feet, the width of Room 2 is 15 feet the height of the rooms is 8 feet. The volume of Room 1: 10 x 10 x 8 = 800 cubic feet. The volume of Room 2: 10 x 15 x 8 = 1200 cubic feet. If in this example a solid door separates Room 1 from Room 2, the volume of Room 2 could not be used. In this case the maximum BTU/h would be: Maximum BTU/h: 800 x 1000 = 16,000 BTU/h This would be considered a confined space since it can not support the 30,000BTU/h input of the heater and it would be necessary to provide adequate combustion and ventilation air to Room 1. In this example, because there is no door to the adjoining room, the volume of the adjoining room may be added to the volume of the room with the heater to get a total unconfined space. The total unconfined space: 800 + 1200 = 2000 cubic feet. Maximum BTU/h: 2000 x 1000 = 40,000 BTU/h If there are no more fuel burning appliances within this space then the 30,000 BTU/h input of the fireplace is suitable to be installed. This also assumes that the construction of this space is not unusually tight. 50 50 COMBUSTION & VENTILATION AIR PROVISIONS DETERMINING CONFINED OR UNCONFINED SPACE EXAMPLE 1 EXAMPLE 2 ROOM 2 ROOM 1 HEIGHTWIDTHLENGTHWARNING Barriers such as the bottom of a glass door frame placed in front of a gas log set can change the air flow characteristics of the fireplace which in turn can cause the unit to carbon or overheat and malfunction.
