SECTION 3.
Gas Supply and Piping
3.1 Gas Supply and Piping
Gas piping should be supported by suitable
hangers or oor 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 tted 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 liqueed
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.
WARNING
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.
AVERTISSEMENT
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.

Notes:
1. These gures are based on 1/2" (0.12 kPa) water column pressure drop.
2. Check supply pressure and local code requirements before proceeding with work.
3. Pipe ttings must be considered when determining gas pipe sizing.
