LIGHTING INSTRUCTIONS
!
WARNING
Before lighting any type of pilot burner
(standing or intermittent), make certain the
hot water boiler and system are full of water
to minimum pressure of 12 lbs. per square
inch in the system, and also make certain
that the system is vented of air. Refer to the
following appropriate lighting instruction.
LIGHTING PROCEDURE FOR BOILER WITH
INTERMITTENT PILOT SYSTEM
!
WARNING
If you do not follow these instructions exactly,
a re or explosion may result causing property
damage, personal injury or loss of life.
This appliance is equipped with an ignition device which A.
automatically lights the pilot. Do not try to light the
appliance by hand.
Before operating, smell all around the appliance area B.
for gas. Be sure to smell next to the oor because
some gas is heavier than air and will settle on the oor.
Read "What To Do If You Smell Gas" on front page of
this manual.
Use only your hand to push in or turn the gas control C.
knob. Never use tools. If the knob will not push in
or turn by hand, don’t try to repair it, call a qualied
service technician. Force or attempted repair may
result in a re or explosion.
Do not use this appliance if any part has been under D.
water. Immediately call a qualied service technician
to inspect the appliance and to replace any part of the
control system and any gas control which has been
under water.

LIGHTING INSTRUCTIONS
To Turn Off Gas To Appliance
1. Set the thermostat to lowest setting.
2. Turn off all electric power to the appliance if
service is to be performed.
3. Push in gas control knob slightly and turn
clockwise to "OFF." DO NOT FORCE.
GENERAL INSTRUCTIONS
Before seasonal start-up, have a qualied service agency
check the boiler for soot and scale in the ues, clean
the burners and check the gas input rate to maintain
high operating efciency.
!
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
Verify proper operation after service.
The service agency or owner should make certain the
system is lled with water to minimum pressure and
open air vents, if used, to expel any air that may have
accumulated in the system. Check the entire piping
system and, if any leaks appear, have them repaired.
Figure 2 - Circulator
Many circulators like the one pictured in Figure 2
(above) require periodic servicing. The motor usually
has openings at each end to lubricate the bearings.
Put about one half teaspoon of SAE 20 or 30 non-
detergent motor oil in each opening twice a year.
!
CAUTION
Do Not Over Oil!!
Many circulators have an oil opening for the shaft
bearing. This should be oiled at the same time for quiet
operation. Follow the manufacturer's instructions for
oiling the shaft bearing.
The venting system should be inspected at the start
of each heating season. Check the vent pipe from the
boiler to the chimney for signs of deterioration by rust
or sagging joints. Repair if necessary. Remove the
vent pipe at the base of the chimney or ue and using
a mirror, check vent for obstruction and make certain
the vent is in good working order.

GENERAL INSTRUCTIONS
Before seasonal start up it is advisable to have a certied
service agency check the boiler for soot and scale in the
ues, clean the burners and check the gas input rate to
maintain high operating efciency. The service agency
should make certain the system is lled with water to
minimum pressure and open air vents - if used - to expel
any air that may have accumulated in the system. The
entire piping system should also be checked and if any
leaks appear, they should be repaired immediately.
The venting system should also be inspected at the start
of each heating season. The vent pipe from the boiler
should be checked for signs of deterioration or sagging
joints. Repair if necessary.
The following procedure should be followed to clean and
check the ue gas passageways:
Remove the burners from the combustion chamber 1.
by raising the burners 1. up from the manifold
orices and pulling toward the front of the boiler,
(See Figure 4)
Disconnect the vent pipe from the vent adapter.2.
Remove the jacket front panel. (See Figure 5)3.
Check venter assembly suction pressure.4.
Connect a slope manometer between the venter •
and the pressure switch with a tee and additional
tubing and connectors.
Turn the boiler on and read suction pressure on •
the manometer. Reading should be negative (-)
.55 ± .05 inches of water column or higher for
the DV50 thru 150 and negative (-) .65 ± .05
inches of water column or higher for the DV200.
If this reading is not attainable, contact a certied
service agency.
Remove the ue collector and venter assembly 5.
from the boiler castings by loosening the hold-down
bolts located on each side of the ue collector. (See
Figure 3)
Visually inspect the venter assembly for any unusual 6.
wear or dirt build up.
If venter has oil cups lubricate venter motor once a 7.
month during the heating season with a few drops
of nondetergent motor oil (SAE 20 or 30). Do not
over oil.
Place a sheet of heavy paper or similar material in 8.
the bottom of the combus8. tion chamber and brush
down the ue passageways. The soot and scale will
collect on the paper and is easily removed with the
paper.
A visual check of the main burner and pilot ames
should be made at the start of the heating season and
again in mid-season.
The main burner ame should have a well dened inner
blue mantel with a lighter blue outer mantel. (See
Figure 6) If the ame does not appear this way, check
the burner throats and burner orices for lint or dust
obstructions.
The pilot ame should envelop 3/8 to 1/2 inch of the
tip of the ignition electrode. To adjust the pilot ame,
remove the pilot adjustment cover screw on the gas valve
and turn the inner screw clockwise to decrease
or counterclockwise to increase the pilot ame.
See Figure 1. Be sure to replace the cover screw after
adjustment to prevent possible gas leakage.
The burners and pilot should be checked for signs of
corrosion, rust or scale build-up, and cleaned with a
nylon bristle brush.
The area around the boiler must be kept clear and free
of combustible materials, gasoline and other ammable
vapors and liquids.
The free ow of combustion and ventilating air to
the boiler and boiler room must not be restricted or
blocked.
In the event the ow of combustion products through
the ueways or the boiler venting system becomes
blocked, a ame roll-out safety switch will shut off the
main burner gas. See Figure 5. If this condition occurs,
do not attempt to place the boiler in operation. Contact
a qualied service agency.
It is suggested that a certied service agency be
employed to make an annual inspection of the boiler
and heating system. They are experienced in making
the inspection outlined above and in the event repairs
or corrections are necessary, they can make the proper
changes for safe operation of the boiler.
