Page 6: Handling & Installation
6. Materials for flue venting that cannot withstand 480 F (249 C) should not be installed with the Heatco HP Series furnaces. 7. A condensate drain fitting is provided in the flue box. If module is located downstream of the cooling system, a drain tube must be connected to this fitting to drain condensate formed in tubes during air conditioning operation. -
Page 7: Furnace Module Application & Airflow Distribution
Furnace Module Application & Airflow Distribution All HP product series heaters ship standard with a heat exchanger sheet metal wrapper that defines the air tunnel clearances around the heat exchanger. If the air tunnel opening is larger than heater profile, provide panels that fasten to the heat exchanger sheet metal wrapper to block by-pass air and direct all airflow over the heat exchanger as shown in Figure 2 below. -

The maximum temperature rise across any one unit in series must not exceed 125 F. This could cause nuisance safety trips or even failure of components. When installing units in series, the modulating unit should be located furthest downstream in the heating assembly. - Page 10 Pressure in the vent duct is positive up to the discharge opening and all vent connections in the vestibule area should have joints sealed to prevent leakage of flue gases into the combustion air supply. The vent discharge opening should be located to provide an unobstructed discharge to the outside and should be located as far from the combustion air inlet as possible but must always be located in the same pressure zone as the combustion air inlet.
