PRESSURE DROP TABLE (See INDEX: “Gas Connections” for further details).
The BTU’s for each appliance are listed in the
tables below for reference. Find the maximum
BTU requirements for the appliance(s) purchased
adding the combined BTU’s together. Cross
reference the total BTU’s against “Table 3” to
determine the maximum allowable supply line
length for the BTU’s required. If the supply line
length available does not support the BTU
requirements, the pipe size will need to be
changed accordingly. Please contact a certified
gas technician for additional size options.
