8W415-0379 / C / 03.12.103.0 INSTALLATIONTo determine the volume of the room where the appliance is to be installed, multiply the width x the length xthe ceiling height of that room measured in feet. If any adjoining rooms are connected by grilles or openingssuch as kitchen pass-throughs, 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 thespace 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 waterappliance, etc. Do not include direct vent gas appliances which draw their input and output air from and to theoutdoors.Unusually tight construction is defined as construction where:A) Walls and ceilings exposed to the outside atmosphere have a continuous water vapour retarder with arating of 1 perm (6 x 10-11 kg per pa-sec-m2) or less with openings gasketed or sealed, andB) Weather stripping has been added on openable windows and doors, andC) Caulking or sealants are applied to areas such as joints around window and door frames, between soleplates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical,and gas lines, and at other openings.An unvented room appliance is recommended for use as a secondary heat source rather than as a primarysource. Gas combustion produces water vapour which could occur at the rate of approximately one ounce ofwater for every 1,000 BTU/hr of gas input. During the cold weather season, indoor humidity levels tend to below. Consequently, this water vapour can enhance the living space. However if a problem should occur:A) Ensure sufficient combustion and circulation airB) Use a dehumidifierC) Do not use the unvented room appliance as a primary heat sourceWithout sufficient fresh air for proper operation, poor fuel combustion can result. Carbon Monoxide is a resultof poor combustion.If additional fresh air is required, use one of the methods described in the National Fuel Gas Code, ANSIZ223.1, Section 5.3 or the applicable local code.! WARNINGIF THE AREA IN WHICH THE APPLIANCE MAY BE OPERATED IS SMALLER THAN THAT DEFINED ASAN UNCONFINED SPACE OR IF THE BUILDING IS OF UNUSUALLY TIGHT CONSTRUCTION, PROVIDEADEQUATE COMBUSTION AND VENTILATION AIR BY ONE OF THE METHODS DESCRIBED IN THENATIONAL FUEL GAS CODE ANSI Z223.1, SECTION 5.3 OR THE APPLICABLE LOCAL CODE.17.1This appliance shall not be installed in a confined space or unusually tight construction unless provisions areprovided for adequate combustion and ventilation air.The National Fuel Gas Code, ANSI Z223.1 defines a confined space as a space whose volume is less than 50cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in thatspace 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 communicatingdirectly with the space in which the appliances are installed, through openings not furnished with doors areconsidered a part of the unconfined space.The GVF42 is rated at 30,000 BTUs per hour for natural gas and 30,000 BTUs for propane and therefore re-quires a minimum unconfined space of 1,500 cubic feet.3.1 COMBUSTION AND VENTILATION AIR PROVISIONS3.2 DETERMINING CONFINED OR UNCONFINED SPACE
