CHECK GAS SUPPLY
The gas pipe to your boiler must be the correct size for the
length of the run and for the total Btu per hour input of all
gas utilization equipment
connected
to it. See Fig. 12 for
the proper size. Be sure your gas line complies with local
codes and gas company requirements.
The
boiler
and
its individual
shutoff
valve
must
be
disconnected
from the gas supply piping system during any
pressure testing of that system at test pressures in excess
of V2 psig (3.5 kPa).
The boiler must be isolated from the gas supply piping system
by closing its individual
manual shutoff valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than V2psig (3.5 kPa).
CONNECTING THEGASPIPING
Refer to Fig. 13 for the general layout at the boiler. It shows
the basic fittings you will need. The gas line enters the boiler
from the right side.
The following rules apply:
1. Use only those piping materials and joining methods
listed as acceptable by the authority having jurisdiction,
or in the absence of such requirements, by the National
Fuel Gas Code, ANSI Z223.1-latest revision.
2. Use pipe joint compound
suitable for LP gas on male
threads only.
3. Use ground joint unions.
4. Install a sediment trap upstream of gas controls,
5. Use two pipe wrenches when making the connection
to the gas valve to keep it from turning.
6. Install a manual shut-off valve in vertical pipe about 5
feet above floor.
7. Tighten all joints securely

CHECKING
THE GAS PIPING
Upon completion of piping, check immediately for gas leaks.
Open the manual shut-off valve. Test for leaks by applying
soap suds (or a liquid detergent) to each joint. Bubbles
forming indicate a leak. CORRECT EVEN THE SMALLEST
LEAK AT ONCE.
I
WARNING
Never use a match or open flame to test for leaks.
