CARBON MONOXIDE POISONING HAZARD
Special Warning for Installation of Furnace or Air Handling Units in Enclosed Areas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide producing devices (such as an automobile, space heater, gas water heater, etc.) should not be operated in enclosed areas such as unventilated garages, utility rooms or parking areas because of the danger of carbon monoxide (CO) poisoning resulting from the exhaust emissions. If a furnace or air handler is installed in an enclosed area such as a garage, utility room or parking area and a carbon monoxide producing device is operated therein, there must be adequate, direct outside ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which can occur if a carbon monoxide producing device continues to operate in the enclosed area. Carbon monoxide emissions can be (re)circulated throughout the structure if the furnace or air handler is operating in any mode.
CO can cause serious illness including permanent brain damage or death.

ACCESSIBILITY CLEARANCE, WHERE GREATER, SHOULD TAKE PRECEDENCE OVER MINIMUM FIRE PROTECTION CLEARANCE.
A gas-fired furnace for installation in a residential garage must be installed so that the ignition source and burners are located not less than eighteen inches (18") above the floor and is protected or located to prevent physical damage by vehicles.
A gas furnace must not be installed directly on carpeting, tile, or other combustible materials other than wood flooring.
WARNING
A SOLID METAL BASEPLATE IS SUPPLIED WITH THIS FURNACE. THIS BASEPLATE MUST BE IN PLACE AND SEALED AIR TIGHT WHEN THE FURNACE IS INSTALLED WITH SIDE RETURN AIR DUCTS. FAILURE TO DO SO MAY PERMIT COMBUSTION PRODUCTS, INCLUDING CABON MONOXIDE, TO ENTER THE LIVING SPACE AND CREATE POTENTIALLY HAZARDOUS CONDITIONS SUCH AS CARBON MONOXIDE POISONING OR DEATH. FULL SIZE RETURN AIR DUCT OPENINGS MUST BE UTILIZED. EMBOSSES ARE PROVIDED FOR THIS PURPOSE.
Before proceeding with this installation check the following:
• Correct clearance from combustible materials
• Adequate accessibility for servicing
• Flooring is not carpet or any other combustible material, except wood
• Adequate combustion / ventilation air is supplied
• Metal base plate is in place when using side(s) for return air
• In a garage, the furnace has been adequately elevated and protected from vehicle damage
• Furnace area is free of flammable materials and vapors such as gasoline
COMBUSTION AIR
The GMNT furnace can be installed either as a Direct Vent (2 pipe) or a Non-Direct Vent (1 pipe) appliance. If installed as direct vent appliance, the combustion air is to be taken from the outdoors via a 2" or 3" schedule 40 PVC pipe and terminate at the furnace burner box. As a non-direct vent furnace, the combustion air is taken from the area which the furnace is installed. Avoid combustion air sources that contain flammable fumes and vapors, and gasses such as carbon monoxide, hydrogen sulfide, ammonia, chlorine, and halogenated hydrocarbons.
Direct Vent Combustion Air. As shown in the following illustration, the combustion air pipe is to originate at the furnace’s cabinet and terminate outside of the building. The diameter of the PVC combustion air pipe depends upon the furnace size, the length of pipe, and the quantity of fittings employed. The table found in the “Combustion/Vent Pipe Size” section of this manual outlines these sizing requirements. As a direct vent installation, the “Air for Combustion and Ventilation Air” requirements found in ANSI Z223.1, section 5.3 is not required for the furnace to operate correctly. However, other fuel burning appliances located in the same space as the furnace may still require that the area be serviced with Combustion and Ventilation Air consistent with ANSI Z223.1, section 5.3.
WARNING
COMBUSTIBLE MATERIAL MUST NOT BE PLACED ON OR AGAINST THE FURNACE CABINET. THE AREA AROUND THE FURNACE MUST BE KEPT CLEAR AND FREE OF ALL COMBUSTIBLE MATERIAL INCLUDING GASOLINE AND OTHER FLAMMABLE VAPORS AND LIQUIDS. THE USER MUST BE CAUTIONED THAT THE FURNACE AREA MUST NOT BE USED AS A BROOM CLOSET OR FOR ANY OTHER STORAGE PURPOSE.

Attaching Combustion Air Intake Fitting. A coupling for attaching the combustion air fitting to the furnace cabinet is included in a plastic bag packaged with the furnace. The fitting is sized to accept a 3" diameter PVC pipe. In certain situation, a 2" diameter pipe can be used for this application. Refer to the combustion/ vent table for sizing requirements. Attach the fitting to the cabinet using (4) #10 x 1/2" sheet metal screws (field supplied). If a right hand entrance is preferred, the plug installed on this side is to be removed and reinstalled in the left side opening.
Non-Direct Vent Combustion Air. If the furnace is to be installed as a non-direct vent appliance, the combustion air pipe outlined previously is not used.
As a non-direct vent furnace, this must be installed in accordance with the combustion and ventilation air requirements found in ANSI Z221.3, section 5.3. When installed as a non-direct vent furnace in an area, which is deemed as a confined area, see (ANSI Z223.1, section 1.7, “Space, Confined”) the requirements are as follows:
All Combustion Air Taken From The Inside Of The Building. When installed as a non-direct vent furnace and
indoor air is used as the combustion air source, the space is to be provided with (2) permanent openings communicating directly with an additional room(s) of sufficient volume so that the combined volume of all spaces meets the criteria of an unconfined area. The total input of all gas burning equipment shall be used to determine the minimum size of each opening. Each opening shall be sized to be a minimum of 1 square inch of free area per 1,000 Btu/hr of combined input of gas utilization equipment in the area. The minimum area for each opening shall not be less than 100 square inches, and the minimum dimension of these openings shall not be less than 3 inches. One opening shall commence within 12 inches of the top of the area, while the other opening shall commence within 12 inches of the bottom of the area.
All Combustion Air Taken From Outdoors. If installed as a non-direct furnace and outdoor air is selected as the combustion air source, then area shall be serviced with an opening(s) communicating directly with the outdoors by either of the following two methods. When calculating the minimum area for each opening, the combined input of all gas utilization equipment is to be considered. Also, the minimum dimension for any opening shall not be less than 3 inches.
Method 1..... Two permanent openings communicating
directly with the outdoors via. horizontal ducts shall be sized to be a minimum of 1 square inch per 4,000 Btu/hr or, two permanent openings communicating directly with the outdoors via. vertical ducts shall be sized to be a minimum of 1 square inch per 2,000 Btu /hr.
Method 2..... One permanent opening communicating
directly with the outdoors via a horizontal duct. This opening/duct shall be sized to be equal to 1 square inch per 3,000 Btu / hr, but not less than the sum of the areas all of the vent connectors in the confined space.
When installed as a direct vent furnace and NOT using the concentric vent kit CVK-00 option, the combustion air is to be terminated in the following manner;
OPTIONAL INLET SCREEN
COMBUSTION
AIR INTAKE
If the optional concentric vent kit (CVK-00) is used, follow the instructions provided with this accessory.
SOURCE OF COMBUSTION AIR
The recommended source of combustion air is to use the outdoor air supply. However, the use of indoor air in most applications is acceptable except as follows;
1. If the furnace is installed in a confined space, the necessary combustion must come from outdoors by way of the attic, crawl space, or direct opening to the outside.
2. If indoor combustion is used, there must be no exposure to the substances listed in #3 below.
3. The following installations may require OUTDOOR AIR for combustion, due to chemical exposures;
• Commercial buildings
• Buildings with indoor pools
• Furnaces installed in laundry rooms
• Furnaces installed in hobby or craft rooms
• Furnaces installed near chemical storage areas
Exposures to the following substances in the combustion air supply may also require OUTDOOR AIR for combustion;
• Permanent wave solutions
• Chlorinated waxes and cleaners
• Chlorine based swimming pool chemicals
• De-icing salts or chemicals
• Carbon tetrachloride
• Halogen type refrigerants
• Cleaning solvents (such as perchloroethylene)
• Printing inks, paint removers, varnishes, etc.
• Hydrochloric acid
• Cements and glues
• Antistatic fabric softeners for clothes dryers
• Masonry acid washing materials
VENTING
ANNUAL inspections of the furnace and it’s vent / combustion air supply is strongly recommended. It is the contractor’s responsibility to inform the user of this importance. All venting shall be in accordance with Part 7; Venting of Equipment, of the National Fuel Gas Code, ANSI Z223.1, or applicable local building and/ or air conditioning codes.
PROPER INSTALLATION OF THE VENT / COMBUSTION AIR SYSTEMS IS CRITICAL TO SAFE OPERATION OF THIS APPLIANCE. CAREFULLY READ AND UNDERSTAND THE INSTRUCTIONS IN THIS SECTION. EACH VENT AND COMBUSTION AIR SUPPLY PIPE MUST SERVE ONLY ONE
IO-213D 2/04

APPLIANCE. DO NOT CONNECT TO AN EXISTING VENT OR CHIMNEY UNLESS IT CONFORMS TO ALL PROVISIONS IN THIS INSTRUCTION BOOKLET. THE VENT MUST TERMINATE
OUTDOORS.
VENT/COMBUSTION AIR SUPPLY PIPE LENGTHS
Elbows must be long radius types. (Quarter bends or DWV). The maximum length of the vent pipe and the combustion air supply pipe is 100 feet each.
Model Vent @ Vent @ more Comb. Air @ Comb. Air @
GMNT 45 ft. than 45 ft. More than 45
040-3 2 in. 3 in. 2” 3”
060-3 2 in. 3 in. 2” 3”
080-4 3 in. 3 in. 3” 3”
100-4 3 in. 3 in. 3” 3” 120-5 3 in. 3 in. 3” 3”
or less 45 ft. or less

Chart assumes a maximum of 4 - 90° elbows. For excess of 4 elbows decrease length by 7.5 ft. per elbow. A maximum of 6 elbows is acceptable. The use of two 45° over one 90° is preferred. Do not count the termination as an elbow.
Minimum vent length is 6 ft. for vertical and horizontal runs. There is no minimum combustion air supply pipe length.
These furnaces are a condensing type appliance. The products of combustion are recirculated through a secondary coil. During this process the flue products are brought to a point below dew point. Thus the moisture present in the flue products condenses leaving a liquid by-product. This by-product must be removed from the furnace and it’s collection system.
In addition, the vent temperatures are also considerably lower than conventional furnaces. This allows the use of low temperature plastic as the vent system. The recommended plastic is schedule 40 PVC, ABS, DWV (or equivalent if allowed by local code). See the previous chart for proper sizing. The use of two 45° elbows is suggested over the use of a single 90° elbow. The vent pipe must slope toward the furnace to properly drain the condensate. The drain trap and related parts must be installed as shown in the illustrations. Failure to follow these instructions can cause products of combustion including CARBON MONOXIDE entering the dwelling.
IF THIS FURNACE IS INSTALLED IN AN ATTIC OR SIMILAR AREA WHERE CONDENSATE OVERFLOW MAY BE A PROBLEM, AN AUXILIARY DRAIN PAN MUST BE INSTALLED UNDER THE FURNACE WITH THE AUXILIARY DRAIN LINES ROUTED TO THE OUTDOORS TO PREVENT WATER DAMAGE CAUSED BY LEAKS.
THE COMBUSTION PRODUCTS AND MOISTURE IN THE FLUE GASES WILL CONDENSE. THE CONDENSATE MAY FREEZE ON THE EXTERIOR WALL AND SURROUNDING SURFACES. SOME DISCOLORATION OR ETCHING IS TO BE EXPECTED.
THE VENT AND COMBUSTION AIR SUPPLY PIPES MUST BE INSPECTED ANNUALLY.
Visually check the vent terminal and combustion air supply pipe screens, clean if necessary. Visually check for blockage of the condensate disposal system. Hoses may
be disconnected to determine that proper flow is maintained. Should an obstruction be observed, it can be dislodged by forcing a stream of water through it using a device such as a garden hose.
Materials and procedures must conform to: The ASTM Standards. Pipe and Fittings ASTM 1785, D2465 and D2266 PVC Primer and Solvent Cement ASTM D2564 Procedure for Cementing Joints ASTM D2855 (ref.) This appliance may be vertically or horizontally vented.
HORIZONTAL THROUGH THE WALL VENTING
This appliance may be horizontally vented through an exterior wall following the applicable instructions in the “VENTING” section in conjunction with these additional requirements. A wall sleeve must be used.
ALL HORIZONTAL VENT INSTALLATIONS MUST BE MADE IN ACCORDANCE WITH THESE INSTRUCTIONS.
When selecting which exterior wall to penetrate, the following items should be taken into consideration:
1. Layout the combustion air and vent system to avoid the possibility of interference with beams, poles, posts, electrical wiring, plumbing, etc.
2. When possible, the combustion air and vent termination should not be subjected to prevailing winds.
3. The combustion air intake and vent termination must be located at least twelve (12) inches above expected snowfall. Consideration should be made to past unusual snowfalls.
DO NOT locate the terminal less than seven (7) feet above
public walkways. This applies to steps and stairwells.
DO NOT locate the termination areas where condensate
may present a problem such as flowerbeds, patios, etc.
DO NOT locate within four (4) feet of a gas meter, electric
meter, or gas regulator; (3) feet in Canada
DO NOT locate the vent terminal within four (4) feet of an
adjacent building.
DIRECT VENT INSTALLATION - DO NOT locate the vent
terminal within twelve (12) inches of an operable window or door.
NON-DIRECT VENT INSTALLATION - DO NOT locate the
vent terminal less than (12) inches above a door or operable window.
NON-DIRECT VENT INSTALLATION - DO NOT locate the
vent terminal less than (4) feet below or (4) feet horizontally from any door, window or gravity air inlet into any building.
DO NOT locate the vent terminal less than three (3) feet
above, or (10) feet horizontally from, a forced air inlet into any building, other than the combustion air supply pipe.
DO NOT locate the vent terminal within three (3) feet of an
inside corner of a building or structure. Minor corners created by fireplace chimneys are excluded from this requirement.
To protect the exterior surface from staining due to the condensate, an aluminum plate or similar material may be installed surrounding the termination. This plate should extend approximately two (2) feet from the termination.
