5WS-415-131 / A / 09.11.00ROOM 2ROOM 1COMBUSTION AND VENTILATIONAIR PROVISIONSThis heater shall not be installed in a confinedspace or unusually tight construction unless pro-visions are provided for adequate combustion andventilation air.This fireplace must be installed against a finishedwall. Do not install against a vapour barrier orexposed insulation.The National Fuel Gas Code, ANSI Z223.1 defines a con-fined space as a space whose volume is less than 50cubic feet per 1,000 Btu per hour (4.8 m 3 per kW) of theaggregate input rating of all appliances installed in thatspace and an unconfined space as a space whose vol-ume is not less than 50 cubic feet per 1,000 Btu per hour(4.8 m 3 per kW) of the aggregate input rating of all appli-ances installed in that space. Rooms communicating di-rectly with the space in which the appliances are installed,through openings not furnished with doors are consid-ered a part of the unconfined space.The GVF30 is rated at 30,000BTUs per hour andtherefore requires a minimum unconfined spaceof 1,500 cubic feet.DETERMINING CONFINED OR UNCONFINEDSPACE: To determine the volume of the room where theheater is to be installed, multiply the width x the length x theceiling height of that room measured in feet. If any adjoin-ing rooms are connected by grills or openings such askitchen pass-throughs, etc., the volume of those roomsmay be added to the total.Multiply the room volume by 1000 and divide this amountby 50 to determine the maximum Btu/hr that the space cansupport with adequate combustion and ventilation air.Add the Btu/hr of all fuel burning appliances located withinthe space such as gas furnace, gas water heater, etc. Donot include direct vent gas appliances which draw theirinput and output air from and to the outdoors.WARNING: If the area in which the heater may be oper-ated is smaller than that defined as an unconfined spaceor if the building is of unusually tight construction, provideadequate combustion and ventilation air by one of themethods described in the National Fuel Gas Code ANSIZ223.1, Section 5.3 or the applicable local code.INSTALL ATIONFIGURE 1Room Volume = Length x Width x HeightMax BTU/hr = Room Volume x 1000 ÷ 50If 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 feetthe 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.EXAMPLE 2If in this example a solid door separates Room 1 fromRoom 2, the volume of Room 2 could not be used. In thiscase the maximum BTU/h would be:Maximum BTU/h: 800 x 1000 = 16,000 BTU/hThis would be considered a confined space since it cannot support the 30,000BTU/h input of the heater and itwould be necessary to provide adequate combustion andventilation air to Room 1.EXAMPLE 1In this example, because there is no door to the adjoiningroom, the volume of the adjoining room may be added tothe volume of the room with the heater to get a totalunconfined space.The total unconfined space: 800 + 1200 = 2000 cubic feet.Maximum BTU/h: 2000 x 1000 = 40,000 BTU/hIf there are no more fuel burning appliances within thisspace then the 30,000 BTU/h input of the fireplace is suit-able to be installed. This also assumes that the construc-tion of this space is not unusually tight.H E I G H TH E I G H TH E I G H TH E I G H TH E I G H TW I D T HW I D T HW I D T HW I D T HW I D T HL E N G T HL E N G T HL E N G T HL E N G T HL E N G T H5050
