7.1 General
Use piping materials and joining methods acceptable •
to authority having jurisdiction. In absence of such
requirements:
USA - National Fuel Gas Code, ANSI Z223.1/NFPA •
54
Canada - Natural Gas and Propane Installation Code,
•
CAN/CSA B149.1
Size and install gas piping system to provide suffi cient •
gas supply to meet maximum input at not less than
minimum supply pressure. See Table 5.
Support piping with hooks straps, bands, brackets,
•
hangers, or building structure components to prevent or
dampen excessive vibrations and prevent strain on gas
connection. Boiler will not support piping weight.
Use thread (joint) compound (pipe dope) suitable for
•
liquefi ed petroleum gas.
Provide sediment trap up stream of gas valve.
•
Install manual main shutoff valve outside of jacket. See •
fi gure 7-2.
7.2 Conversion Kit Instructions
See Gas Conversion Kit Instructions included with Boiler. •
CAUTION
WHAT TO DO IF YOU SMELL GAS
Do not try to light any appliance. •
Do not touch any electrical switch; do not use any •
phone in your building.
Immediately call your gas supplier from a neighbor’s
•
phone. Follow gas supplier’s instructions.
If you cannot reach your gas supplier, call the fi re
•
department.
