• The gas supply line shall be gas tight, sized and so

installed as to provide a supply of a gas sufficient to

meet the maximum demand of the heater without

loss of pressure.

• A shut off valve and appliance connector valve

should be installed in the upstream of the gas line to

permit servicing.

• Flexible pipe and any appliance connector valve

used for gas piping shall be types approved by

nationally recognized agencies.

• Any compound used on the threaded joint of the gas

piping shall be a type which resists the action of

liquefied petroleum gas (propane / LPG).

• After completion of gas pipe connections all joints

including the heater must be checked for gas

tightness by means of leak detector solution, soap

and water, or an equivalent nonflammable solution,

as applicable. (Since some leak test solutions,

including soap and water, may cause corrosion or

stress cracking, the piping shall be rinsed with water

after testing, unless it has been determined that the

leak test solution is non-corrosive.)

• Check the gas supply pressure immediately

upstream at a location provided by the gas

company. Supplied gas pressure must be within the

limits shown in the Specifications section.

• Refer to an approved pipe sizing chart if in doubt

about the size of the gas line.

• Install manual gas cut-off valve so that it can be

accessed for easy operation. Do not conceal

manual cut-off valve behind back spacer.

WARNING

When connecting the gas valve or other gas

components in the gas line, use a backup wrench to

ensure the connection is gas tight.
