Bradford-White Corp BMT2H Manual De Usuario

Page 15

Gas piping should be supported by suitable 

hangers or floor stands, not by the appliance.

The Brute Deluxe’s gas train allows the user to 

pipe the gas from either the right side or the left side 

of the unit. As shipped, the right side of the gas train is 

capped off, and there is a manual valve on the left side. 

If desired, the manual valve on the left side of the gas 

train may be moved to the right side, and the cap on 

the right side may be moved to the left. 

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 

Deluxe appliances are equipped to operate at 

elevations up to 10,000 feet (3050m). Brute 

Deluxe appliances may be adjusted to operate 

properly at altitudes above 2500 feet (see Section 

6.5.2) and the input will be reduced if the heating 

value of the gas supply is below sea level values.

2.  The maximum inlet gas pressure must not 

exceed 13" w.c. (3.2kPa). The minimum inlet gas 

pressure is 5 in. w.c. (1.2 kPa).

3.  Refer to 

Table 7

, size supply.

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 0.5 psig (3.45 kpa).

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 0.5 psig (3.45 kpa).

10.  The appliance and its gas connection must be 

leak tested before placing it in operation.

11.  Purge all air from gas lines.

Do not use open flame to check for leaks. An open 

flame could lead to explosion, which could result in 

property damage, serious injury or death.

Ne recherchez pas les fuites avec une flamme nue. 

Une flamme nue peut provoquer une explosion qui 

peut causer des dommages matériels, de sérieuses 

blessures corporelles ou la mort.

NOTE: The Brute Deluxe 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.

2.  Check supply pressure and local code requirements before proceeding with work.

3.  Pipe fittings must be considered when determining gas pipe sizing
