9600 CB SECTION 1. Introduction and Unpacking 1.1 General Instructions It is important for you to take a few minutes to review this Installation and Operating Instructions manual before you begin installation. This will make installing and operating the unit easier and faster. Direct vent-sealed combustion: The 9600 CB boiler does not and should not take combustion air from inside the building. All of the air is drawn in from outdoors through a 3-inch diameter plastic pipe.

The CB unit and its individual shutoff valve must be disconnected from the gas supply piping during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45kpa). It must be isolated from the gas supply system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG (3.45kpa).

9600 CB Page 13 Do not use automotive anti-freeze. Maintaining a mixture of minimum 65% water and maximum 35% properly inhibited HVAC glycol, which contains an antifoamant, is the preferred method of freeze protection for CB boilers. Percentage of glycol used in the CB boiler must not exceed 35%. Typically, this mixture will serve as burst protection for temperatures down to approximately -35°F (30°C). IMPORTANT NOTES: Different glycol products may provide varying degrees of protection.

After it has been determined that each appliance remaining connected to the common venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to the previous conditions of use. Any improper operations of the common venting system should be corrected so the installation conforms with 1). the National Fuel Gas Code, ANSI Z223.1-latest edition or 2). CSA B149.1.
