INTRODUCTION This 95% efficient gas fired furnace series is CGA / AGA d vent pressure) non-direct or direct vent central forced air fur- nace. It is an upflow , downflow , horizontal left and right fur- nace suitable for residential and light commercial heating applications from 54,000 to 108,000 BTU/Hr .
DANGER WHA T TO DO IF YOU SMELL GAS: • DO NOT TRY TO LIGHT ANY APPLIANCE • DO NOT TOUCH ANY ELECTRICAL SWITCH; DO NOT USE ANY PHONE IN YOUR BUILDING • IMMEDIA TEL Y CALL YOUR GAS SUPPLIER FROM A N EIGHBOR’S PHONE, OR A CELLULAR PHONE FROM A LOCA TION WELL AW A Y FROM THE BUILDING.
CODES: This furnace must be installed: • In accordance with all local codes, bylaws and regulations by those authorities having jurisdiction • In the United States, this furnace must be installed in a ccordance with the current ANSI Z223.
FURNACE SIZING The maximum hourly heat loss for each heated space shall be calculated in accordance with the procedures described i n Manual J titled, "Load Calculation" published by the Air.
Other Considerations: 1. This furnace is not to be used for temporary heating of buildings or structures under construction. 2. If this furnace is to be used with air conditioning and is t o be instal.

DUCTWORK Proper airflow is required for the correct operation of this furnace. Insufficient airflow may cause erratic operation, c ould cause the furnace to cycle on the high temperature limit, and may damage the heat exchanger .
WARNING THERE MUST NOT BE ANY OPENINGS BETWEEN THE BLOWER DIVISION P ANEL AND THE COMBUSTION COMP ARTMENT . THE BLOWER COMP ARTMENT IS UNDER GREA TER SUCTION THEN THE COMBUSTION COMP AR TMENT AND CAN PULL COMBUSTION AIR FROM THE BURNERS AND CAUSE INCOMPLETE COMBUSTION AND ERRA TIC FURNACE OPERA TION.
Instructions for Re-orienting Air Inducer T his furnace comes assembled ready for left side or vertical venting. Rotate the inducer 180 degrees to exit the right hand side. 1. Disconnect inducer wire connections. 2. Remove pressure switch hoses. 3. Remove pressure switches.
10 C C A B A B A B Upflow Installation The combustion air and exhaust vent may exit through the top, left or right side of the cabinet when viewed in the upflow position. The inducer is installed so that the exhaust vent may exit the top and left sides without requiring rotation.
11 Downflow Installation When the furnace is installed in the downflow position the combustion air and exhaust vent may exit through the left or right side of the cabinet (when viewed in the upflow position.). The inducer is installed so that the left side exits require no rotation.
12 C A B A A B B B A C C The furnace must be installed level or sloping towards the front to facilitate proper drainage. IMPORT ANT It is not permissible to use a rear of the furnace as a return. NOTE The furnace must be installed level or sloping towards the front to facilitate proper drainage.
WARNING DO NOT ALLOW GAS PIPING TO BE ROUTED THROUGH JOIST SP ACES THA T ARE USED FOR RETURN AIR PUR - POSES. DO NOT USE JOIST SP ACES FOR RETURN AIR PURPOSES IF THE JOIST SP ACE ALREADY CONT AINS PLUMBING ST ACKS, CHIMNEY COMPONENTS, ETC.
FIGURE 1 DANGER The following types of installation sites (but not limited to the following) will require OUTDOOR AIR for combustion because of chemical exposures: commercial buildings, buildings with indoor swimming pools, furnaces installed in laundry rooms, furnaces in hobby o r craft rooms, furnaces installed near chemical storage areas.
WARNING READ AND FOLLOW ALL INSTRUCTIONS IN THIS SEC- TION. F AILURE TO PROPERL Y VENT THIS FURNACE CAN CAUSE CARBON MONOXIDE POISONING OR AN EXPLO- SION OR FIRE RESUL TING IN PROPERTY DAMAGE, PER- SONAL INJUR Y OR LOSS OF LIFE.
Guidelines • V enting may be vertical or horizontal. • • Horizontal piping must slope back towards the furnace at a minimum rate of 1/4” to the foot, so that • Horizontal runs must be supported at least every 3 feet.
PROCEDURE: This guide is intended specifically for PVC pipe; however , the general procedure applies to all plastic piping systems. MA TERIALS: PVC Cleaner / Primer and PVC Solvent Cement. After cutting pipe, remove all ragged edges and burrs. This will reduce restriction (pressure drop) throughout the venting and combustion air system.

C oncentric venting terminal kits may be used for this series f urnace. They provide a means of obtaining combustion air a nd exhausting products of combustion utilizing a single penetration through the exterior wall. This can be useful when there is limited wall space available.
If the required clearance to grade or anticipated snow level cannot be obtained with the “straight through” c onfiguration, the exhaust pipe may be “periscoped” up to 2 4” to gain extra height. (Figure 9) In this case, the flue gases may be expelled horizontally .

D E A B C CONDENSA TE NEUTRALIZERS Some local codes may require the use of a condensate neu- tralizer . If the furnace condensate is to be routed to a sep- tic system, it may be advisable to use a condensate neutral- izer . Condensate neutralizers such as the Ward Industries 90+ Neutralizer are available through heating supply whole- salers.
