II. GENERAL INSTRUCTIONS A. VENTING: The OHC furnace venting system must be installed by a qualified service person in accordance with local installation codes and these instructions. In the absence of applicable local codes, conform to the National Fuel Gas Code, NFPA 54/ANSI Z223.1 or latest edition. Installation shall, at least, conform to the following requirements. 1. The exhaust vent/combustion air intake termination specified by Thermo Products, in this m

Care should be taken to design the shortest possible intake and exhaust systems. Each system should contain as few elbows as possible to insure the satisfactory operation of the furnace. However, system length should never be less than 8 ft of pipe with two (2), 90 deg. elbows. For best overall operation of the combustion system, we recommend the actual equivalent lengths for both the constructed intake and the ex

No clearance is required from the outer surface of the thermoplastic piping to combustible materials for fire hazard prevention. No clearance is required from the outer surface of the ventor assembly either. 14. When attaching the 3” PVC to the burner combustion air inlet collar, first apply a bead of RTV sealant to the burner inlet collar only to ensure an a

NOTICE: Ventor assembly must be installed so that it is level. If unit is not level, condensate will leak in to ventor box thru inducer and potentially freeze. 1. The OHC must be installed with the side-wall ventor/ blower assembly. Do Not attempt to operate the OHC without the ventor assembly as this could result in damage to the appliance or home. 2. No clearance is required from the outer surface of the ventor assembly to combustible materials for fire hazard

A. The exit termination of the draft system shall not be less than 7’ above grade when located adjacent to public walkways. B. The venting system shall terminate at least 3’ above any forced air inlet located within 10’ horizontally. C. The venting system shall terminate at least 4’ horizontally from, or 1’ above any door, window or gravity air inlet into the building. D. The vent termination shall be located at least 12” from any opening through which vented gases could enter t

C. Condensate Drain Line Connections: Fig-4 1. The trap/blocked drain switch assembly comes pre-mounted to the underside of blower pan just below the secondary drain port on the right side of the furnace. Prior to installing the drain, the PVC elbow must be sealed to the plastic trap with silicone and then the spring clamp applied. This 0 positioning of the elbow can be turned to right for exiting the right side casing or rotated 180 and exit t

4. A condensate pump may be required when: • a suitable drain is not present, • the drain is above the trap outlet level on the furnace, or • the drain line cannot be sloped downward its full length to the drain. If gravity drainage of the condensate from the furnace to a drain is impractical for any of these reasons, a condensate pump (part #350225) is available from Thermo Products. Follow the pump manufacturer’s instructions for proper installation. 5

If available, the use of ultra-low or low sulfur (less than 0.0015% S and 0.05% S, by weight, respectively), no. 2 fuel oil is highly recommended. Low sulfur fuel oil can help to significantly reduce instances of blockage and corrosion of the oil burner fuel delivery system (especially the nozzle), the furnace heat exchanger, and the flue gas venting system. Air pollutants emitted by the furnace and the typical malodorous smell of oil combustion will be reduced. 1. The use of black
