SECTION 4.
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.
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.
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.
