VENT PIPING AND DRAFT REGULATOR

A. Vent pipes must be installed having the same diameter as the boiler
outlet. (See page 2)
B. Vent pipes and Breaching must be pitched upward a minimum of
21 mm/m ( 1 / ") per foot.

C. Connect vent pipe to the chimney using as few elbows as possible.
D. Horizontal vent connector into the chimney should not be inserted
beyond the inside wall of the chimney.
E. Install barometric draft regulator on vertical or horizontal Breeching,
near chimney, with hinge horizontal and face vertical. See manufac
turer's instructions packed in carton with barometric draft regulator
and page 4.
F. If two or more appliances are used on the same chimney, see
CHIMNEY, page 3 and 4.
G. Make up all joints with minimum air leaks, secure with sheet metal
screws.

OPERATING INSTRUCTIONS

PRECAUTIONS BEFORE STARTING OIL BURNER
Make a positive check of A through H before starting burner:
A. Boiler and system are full of water. All air is vented from system.
See below.
B. All wiring is completed.
C. Oil supply is connected to the burner; nozzle is installed correctly;
oil valve is open at tank.
D. Smokepipe is connected to chimney.
E. All combustible materials are cleared away.
F. Combustion air supply is provided. See page 4.
G. Burner settings are adjusted as per pages 12 14 and as shown on
boiler jacket.
H. Main cast iron door on which burner is mounted is bolted shut and
fiberglass rope seal is making good contact.
* Draft is negative or suction pressure.
CAUTION: DO NOT START THE BOILER UNLESS ALL CLEAN
OUT DOORS ARE SECURED IN PLACE.
WARNING: NEVER OPERATE any natural draft* boiler
(TR Series boiler is a natural draft boiler) with zero draft or
overfire pressure: early failure of the burner, nozzle and
chamber is inevitable if you do. Use a draft gauge, and make
sure that overfire draft* is 0.5 mm (.02"), minimum, during all
operating conditions.
START-UP (COMBUSTION TEST INSTRUMENTS MUST BE USED)
A. Make sure the boiler is installed and wired properly and is full of
water.
B. Open the observation door (on the front, above the burner).
C. Start the oil burner (see burner instructions for bleeding air from oil,
etc.). IMMEDIATELY, set burner air bands to obtain a bright fire
without smoke or oil stain. Set the DRAFT REGULATOR to obtain
0.5 mm (.02") overfire draft*. Take draft reading through slot in
observation door.
D. Close the observation door. Allow the burner to fire for at least one
hour total firing time, to bake out the volatile binders in the combus
tion chamber before taking final combustion readings.
E. By alternate adjustment of the barometric draft regulator, the burner
air regulation and head regulation devices (whichever apply), set for
a trace of smoke and as close to 13% CO
the air bands or shutter (whichever apply) an additional 3 mm (
This should result in zero smoke with NO raw oil on the smoke
paper and a smooth light off. DO NOT ATTEMPT TO SET FIRE BY
EYE. Flame retention burners may appear efficient and smoke free
from an inefficient 7% up to an overly high 14% CO
very low CO can also result in poor ignition and raw (unburned) oil

entering the fire box. At very high CO
flow for any reason will cause incomplete combustion, with high
smoke and dry soot formation in the fire box.
F. If smoke reading is satisfactory, but CO
satisfactory level (12% or better) or overfire draft of 0.5 mm (0.02")
W.C. can not be obtained, check for proper sealing between sec
tions, between burner mounting plate and front section, around
as you can. Then open

. However, a

, any slight decrease in air

can not be increased to a

burner blast tube and around flue collector and collar. If seal is not
satisfactory, reseal with furnace putty or silicone with a temperature
rating of at least 204°C (400° F). (All safety precautions indicated on
material package must be followed.)
G. Once burner and draft have been set up, then smoke, CO
stack temperature should be checked and recorded. If smoke is
greater than trace, review the burner instructions; replace the nozzle
if necessary. Normal smoke to be expected at approximately 13%
CO is zero to a trace.

CLEANING AND FILLING A NEW WATER BOILER
I. BEFORE FILLING WATER BOILER
A. Check burner to be certain it is ready for firing. DO NOT FIRE
into an empty boiler.
B. Be prepared to heat raw water to at least 82°C (180°F). as soon
as it is introduced into the boiler. This procedure will remove
dissolved, corrosive gases.
C. Provide drain line, with valve, from boiler. Use a bottom tapping.
Line and drain must be suitable for handling caustic solution.
II. CLEANING WATER BOILER SYSTEM
A. Prepare a boil out solution of sodium hydroxide (caustic soda)
or tri sodium phosphate.
NOTE: Use caution in handling chemicals. Caustic soda is
harmful to skin, eyes and clothing.
1. Proportions: 2.25 kg per 190 L (1 lb per 50 gal) of system
water.
2. Stir chemical in water until dissolved and pour into the
boiler through a top tapping. Replace plug.
B. Fill the entire system with water.
C. Start the burner, using the start up procedure.
D. Circulate the water through the entire system.
E. Vent the system, including the radiation.
F. Allow boiler water to reach operating temperature, if possible.
G. Continue to circulate the water for a few hours.
H. Shut off the burner.
I. With CAUTION, drain the boiler solution to a safe location. DO
NOT LEAVE SOLUTION SITTING IN SYSTEM OVER 2
HOURS.
J. Wash the water side of the boiler thoroughly using a high pres
sure water stream. Fill and drain the boiler several times.
III. TREATING WATER FOR CORROSION CONTROL
(This is not scale control)
A. Prepare a solution of sodium chromate.
Proportions: 94cc/100L (6 oz. per 50 gallons) of system water.
B. Stir chemical into water until dissolved and pour into the boiler
through a top tapping. Replace plug.
IV. FILLING AND VENTING THE WATER BOILER
A. Refill the system with fresh water.
B. Bring water temperature to at least 82°C (180°F) promptly.
C. Circulate water through entire system.
D. Vent the system, including the radiation.
E. The boiler is now ready to be put into service or on standby.
F. If brand name air control devices are used, venting instructions
furnished with the devices should be followed.
V. SAFETY CHECK FOR CONTROL SYSTEM
High limit control test: Set thermostat high enough for boiler water
temperature to reach high limit control setting. When this tempera
ture is reached, the high limit switch should open, and the burner
should shut off automatically. If the high limit does not operate to
shut off the burner, the high limit or the wiring is faulty. Repair or
replace immediately.
CLEANING AND FILLING A NEW STEAM BOILER
I. BEFORE USING STEAM BOILER
A. Check burner to be certain it is ready for firing. DO NOT FIRE
into an empty boiler.
B. Be prepared to heat raw water to at least 82°C (180°F). as soon
as it is introduced into the boiler. This procedure will remove
dissolved, corrosive gases.
C. Provide drain line, with valve, from boiler. Use a bottom tapping.
Line and drain must be suitable for handling caustic solution.
D. Check for low water cut off operation, see section below for
check out.
