3.Insofar as it is practical, close all building doors and windows and all doors between the space in which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.

4.Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so the appliance will operate continuously.

5.Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle, or smoke from a cigarette, cigar or pipe.

6.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 their previous conditions of use.

7.Any improper operation of the common venting system should be corrected so that the installation conforms to the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, Installation Codes. When resizing any portion of the common venting system, the common venting system should be resized to approach the minimum size as deter- mined using the appropriate tables and guidelines in the National Fuel Gas Code, ANSI Z223.1 NFPA 54 and/or CSA B149.1, Installation Codes.

Gas Supply and Piping

4.1 Gas Supply and Piping

Gas piping should be supported by suitable hangers or floor stands, not the appliance.

Review the following instructions before proceeding with the installation.

1.Verify that the appliance is fitted for the proper type of gas by checking the rating plate. Brute Elite will function properly without the use of high altitude modification at elevations up to 10,000 feet (3050 m).

2.The maximum inlet gas pressure must not exceed 13" W.C. (3.2kPa). The minimum inlet gas pressure is 4" W.C. (1.0kPa).

3.Refer to Tables 6A, 6B, 6C and 6D to size piping.

4.Run gas supply line in accordance with all applicable codes.

5.Locate and install manual shutoff valves in accordance with state and local requirements.

6.A sediment trap must be provided upstream of the gas controls.

7.All threaded joints should be coated with piping compound resistant to action of liquefied petroleum gas.

8.The appliance 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).

9.The unit 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).

10.The appliance and its gas connection must be leak tested before placing it in operation.

11.Purge all air from gas lines.

4.1 Gas Supply and Piping WARNING:

Open flame can cause gas to ignite and result in property damage, severe injury, or loss of life.

NOTE: The Brute Elite appliance and all other gas appliances sharing the gas supply line must be firing at maximum capacity to properly measure the inlet supply pressure. The pressure can be measured at the supply pressure port on the gas valve. Low gas pressure could be an indication of an undersized gas meter, undersized gas supply lines and/or an obstructed gas supply line. Some Brute Elite units are equipped with low and high gas pressure switches that are integrally vent limited. These types of devices do not require venting to atmosphere.
