Unless otherwise noted, the instructions contained within are valid for all of these configurations.
  • Page 5 These Installation and Operating Instructions are intended for use by fully qualified installation technicians. Some localities require the installer/servicer to be licensed. If in doubt, check with local authorities. INSTALLATION: In the USA this furnace must be installed according to the latest edition of the ANSI Z223.1 booklet entitled “National Fuel Gas Code”...

    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.
  • Page 7 GAS PIPING & GAS PIPE CAPACITY TABLE Check the rating plate to make certain that the unit is equipped to burn the type of gas supplied. Care should be taken after the installation of this appliance that the gas control valve is not sub- jected to high gas supply line pressure.
  • Page 8 SIZE* 1 1/4 1050 1 1/2 1600 1100 * Nominal size of Iron Pipe in inches. After the length of pipe has been determined, select the pipe size that will provide the minimum cu- bic feet per hour of gas flow for the required input of the appliance. In the case where more than one appliance utilizes the same supply pipe be sure to consider the sum of all appliances.
  • Page 9 Note: When a combination of outdoor and indoor air is used the system should be designed and adjusted so that the temperature reaching the appliance will not drop below 50 F during heating operation. When this type of system is used the volume of air must not be reduced. Plenum chambers and air ducts must be installed in accordance with the Standard for the Installa- tion of Air Conditioning and Ventilating Systems, NFPA # 90A, or the Standard for the Installation of Warm Air Heating and Air Conditioning Systems, NFPA # 90B.
  • Page 10 WHERE THE MAXIMUM REQUIRED AIR FLOW IS 1800 CFM OR GREATER THE BOTTOM OR BOTH SIDES MUST BE UTILIZED FOR RETURN AIR SUPPLY. NEVER USE THE REAR OF THE FURNACE FOR THE RETURN AIR CONNECTION. WARNING A SOLID METAL BASEPLATE IS SUPPLIED ON THIS FURNACE. THIS BASEPLATE MUST BE IN PLACE WHEN THE FURNACE IS INSTALLED WITH SIDE(S) RETURN AIR DUCTS.

  • Page 11: Rating The Furnace

    The following method should be used in measuring the amp draw of the control circuit to assure proper adjustment of the thermostat heat anticipator RATING THE FURNACE The furnace is supplied with orifices sized for natural gas at altitudes up to 2,000 feet using a heating value of approximately 1,000 Btu/hr, and should not normally require change.

  • Page 12: Timing The Gas Meter

    EXAMPLE: Corrected input for a 100,000 Btu/hr. appliance installed at an altitude of 6.000 ft. utilizing natural gas with a heating value of 1,000 Btu/ft is determined by- Corrected Input = 100,000 - (6,000 X .04) X (100,000 / 1,000) Corrected Input = 100,000 - (240 X 100) Corrected Input = 100,000 - 24,000 Corrected Input = 76,000...
  • Page 13 inability to maintain the proper pressure range will require reorificing. After reorificing, repeat the above steps to insure that the furnace input is adjusted properly. • Turn off gas and electrical supply, remove manometers and replace any plugs that were re- moved.
  • Page 14 This furnace uses a vent pressure switch that prevents the furnace from operating should any por- tion of the vent system become restricted or a venter failure occur. To check this switch, place the furnace in operation and remove the hose from the switch. The gas burners will extinguish. Re- placing the hose will allow the furnace to operate normally.

  • Page 15: Circulating Air Filters

    CIRCULATING AIR FILTERS One of the most common cause of a problem in a forced air heating system is a blocked or dirty filter. Circulating air filters must be inspected monthly for dirt accumulation and replaced if neces- sary. Failure to maintain clean filters can cause premature heat exchanger failure. A new home may require more frequent replacement until all construction dust and dirt is re- moved.

  • Page 16: Service Instructions

    MOTOR LUBRICATION AND MAINTENANCE The circulating air blower is equipped with bearings that are permanently lubricated by the motor manufacturer and require no lubrication. At the time of the monthly filter inspection clean the exte- rior of the circulating air motor, especially around the perimeter air holes to prevent the possibility of overheating due to an accumulation of dust or dirt on the windings and motor casing.

  • Page 17: Removing An Existing Appliance

    HEATING MODE • The furnace control checks for an open main limit (this limit is normally closed). If the main limit is open, the furnace will remain inoperable until the limit is closed. During an open limit the cir- culating air blower and vent blower will be energized. The status light will blink four (4) times. •...

  • Page 18: Inspecting And Cleaning The Heat Exchanger

    a) Seal any unused openings in the venting system; b) Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI Z223.1 or the CAN/CGA B149 Installation Codes and these instructions. Deter- mine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition;...

REMOVE THE FOUR PERIMETER SCREWS, ROTATE THE VENTER TO THE DESIRED POSITION AND REINSERT AND TIGHTEN THE SCREWS. THE ORIFICE PLATE MUST BE ROTATED ALONG WITH THE VENTER ASSEMBLY FOR PROPER COMBUSTION AND IGNITION.
  • Page 24 BLOWER OFF DELAY In the heating mode, the time period between the extinguishing of the burners and the circu- lating blower turning off, is known as the “Blower Off Delay.” This time is factory preset at 150 seconds. The 150 second delay can be changed to 120 or 90 seconds by changing the position of a jumper on the Ignition Control.

An exterior masonry chimney is defined as a “Masonry chimney exposed to the outdoors on one or more sides below the roof line.” The ability to use a clay lined masonry chimney depends on a parameter not associated with interior chimneys.
  • Page 29 GENERAL VENTING REQUIREMENTS The requirements contained herein apply to both Category I draft hood equipped and fan as- sisted combustion appliances. At no time should a venting system listed for a Category II, III, or IV appliance be sized with these tables.
