Suburban DYNAPACK S Series, Installation, Operating And Service Instructions

Page: 4 / 22

GAS PIPING
The Dynapack unit has a ½” pipe connection for the gas line. The size
of the gas piping must be based on the length of the run and not the
connection size. See table 5 for reference pipe sizing.
Consult with the local gas utility or code authority for gas piping instal-
lation.
If local codes allow the use of a flexible gas appliance connector,
always use a new listed connector. Do not use a connector which has
previously serviced another gas appliance.
The gas piping should contain a manual shut off valve with test port
near the furnace in addition to a drip leg and a ground joint union for
servicing. The test port needs to be upstream of the manual shut off
valve for leak testing and adjusting the supply pressure regulator.
The manual shut off valve must be rated for the gas piping test pressure.
If not, then the shut off valve must be removed from the piping system
during testing. Once the gas piping up to the shut off valve has been
tested, the remaining piping to the unit gas valve must be tested. Do
not exceed ½ psig or 14” water column for this test or the gas valve may
be damaged.
CAUTION: Suburban does not recommend the use of flex tubing to
make the gas connections to the unit unless the flex tubing is a high
quality stainless certified by CSA and approved for use by local code.
WARNING!
A pipe thread compound resistant to the action of liquefied petroleum (LP)
and natural gas must be used on all pipe joints.
WARNING!
The gas valve supplied with this furnace is rated at 1/2 psig maximum. Any
higher pressure may rupture the pressure regulator diaphragm and may cause over firing
of the burners and improper burner operation. The over firing may result in the creation of
carbon monoxide which could cause asphyxiation.
WARNING! FIRE OR EXPLOSION HAZARD!
Failure to follow the safety warning
exactly could result in serious injury, death, or property damage.
WARNING!
Never test for gas leaks with an open flame. Use a commercially available
soap solution made specifically for the detection of leaks to check all connections. A fire or
explosion may result causing property damage, personal injury, or loss of life.
CONTROL WIRING
The room thermostat should be installed on an interior wall and near the
return air for the unit. It is recommended that a 5 conductor thermostat
wire be used in case the room thermostat needs power from the unit
transformer.
The low voltage pigtails for the thermostat wiring must be routed to
the outside of the Dynapack unit for connection. The Dynapack unit
contains a second knockout above the control box for this purpose.
The National Electrical Code requires that low voltage wiring be kept
separate from high voltage wiring and cannot be routed through the
same knockout or conduit. Local codes may also require that an
electrical box be installed on the low voltage knockout to contain the
electrical connections.
Follow the thermostat manufacturers instructions for mounting and
wiring. The low voltage is grounded inside the unit control box. See the
attached wiring diagram on page 8.
