Butane or propane gas-fired machines:
Operate on 11” (3.6 oz.) water column pressure. These propane
(LP) gas machines are not equipped with a gas regulator.
Therefore, install on the LP tank a gas regulator (see Figure 3) of
sufficient size to allow for pressure drop from the tank to the
machine.
Figure 3:
Gas Regulator
Warning:
Maximum inlet gas pressure is 0.5 PSI (14” water column or
an 8.9 oz. per square inch).
Install a gas shutoff valve in back of the machine on the gas line with a union
between the valve and the gas regulator (see Figure 4). Prior to operating the
burner system, purge the new lines. If this is not done, starting the burner can
be difficult.

Gas Valve
Guide to gas line pipe size
See Table 2 for the minimum gas line iron pipe size required for gas supply per
length of gas line from the valve side of the meter (Natural Gas) or valve is
based on a pressure drop of 0.03-inch water column pressure and 0.60 specific
gravity. See your gas supplier for assistance if your system has many fittings or
unknown loads.
