Gas Connection

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.
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.
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,

Clearances to Combustibles

When determining where to install the appliance
the clearances to combustibles shown in the
figure must be followed. Also refer to the Safety
Behaviors an d Practices section. The clearance

the piping shall be rinsed with water after
testing, unless it has been determined that the
leak test solution is non-corrosive.)
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.
