- Page 2 A Nameplate and Rating Plate are attached to the front shroud of the duct furnace assembly to identify the model and serial number of this product and ratings for this furnace assembly. These plates must be left attached when the furnace is installed in the product for identification purposes.
- Page 3 The “Listed” equipment manufacturer’s Installation and Operating Instructions should provide all necessary information as required by ANSI Z83.8-CSA 2.6 including but not limited to the following; Installation Codes, Hazard Warnings, operation in chemical environments, gas piping, electrical connection, Lighting Instructions, Sequence of Operation, proper adjustment of minimum firing rate, Manual reset switches, Wiring Diagrams, Clearance to Combustibles, Airflow and Rise ranges, Venting and troubleshooting, annual inspection and maintenance.
- Page 4 Outdoor Installation 1. Vent termination must be located in the same pressure zone as the combustion air inlet and should be located to prevent recirculation of flue gases into combustion air supply. 2. The vent discharge must be the same diameter as the integral vent connector. 3.

- Page 6 Burner Adjustment and Operation Manufacturer’s instructions for proper set-up, adjustment and operation of the power burner installed are provided with this furnace. The burner has been test fired at the factory after installation in the HE duct furnace, however final adjustment is the responsibility of the unit manufacturer.
- Page 7 In applications with constant volume airflow and a high percentage of outside air, it may be necessary to limit burner turndown (ei. minimum firing rate) in order to insure conditions that will avoid prolonged condensation in heat exchanger. These applications are most likely to result in low temperatures on secondary heat exchanger tubes. Bypass duct for these applications should be sized to reduce airflow over the heat exchanger to obtain the highest temperature rise possible (up to 100 F) across the heat exchanger and still provide the desired supply air temperature...
