For safe, efficient operation, the vent damper and all flue
product carrying areas of the appliance
must be checked
annually by you, with particular attention given to deterioration
from corrosion or other sources. If you see corrosion or other
deterioration,
contact your heating contractor
for repairs.
Check vent damper operation as follows:
1. When the boiler is off, check that the vent damper position
indicator points to the closed position, Fig. 11.
2. Turn the thermostat or controller up to call for heat and
check that the vent damper indicator points to the open
position, Fig. 11.
3. Turn the thermostat or controller down again and check
that the vent damper position indicator returns to the closed
position.
4. If you have central air conditioning,
set the thermostat to
COOL and turn it down to call for cooling. Cooling system
should operate.
5. Return thermostat to desired position.
The vent damper must be Inspected
st least once a
year by a trained, experienced
service technician, The
name of the person who originally installed your vent
damper is shown on the installation
label.
MANUAL
OPERATION
OF THE VENT DAMPER
The Effikal vent damper may be placed in the open position
to permit burner operation
by using the "HOLD DAMPER
OPEN"
switch,
located
on the damper
controller.
The
thermostat will control the burner firing as before, while the
damper will remain open. DO NOT turn damper open manu-
ally or motor damage will result. Set switch to "AUTOMATIC
OPERATION" to close vent damper during burner off cycle.
For further information, and for a vent damper troubleshooting
guide, refer to the Effikal manual that was packaged with
the vent damper.

CHECK GAS SUPPLY
The gas pipe to your boiler must be the correct size for the
length of the run and for the 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 V2 psig (3.5 kPa).
CONNECTING THE GAS PIPING
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.
WARNING
1
Never use a match or open flame to test for leaks.
